    Which combination will create the greatest drift hazard?

    • A.

      Low Pressure - Small Orifice .

    • B.

      Low Pressure - Large Orifice

    • C.

      High Pressure - Small Orifice

    • D.

      High Pressure - Large Orifice

    Correct Answer
    C. High Pressure - Small Orifice
    Explanation
    The combination of high pressure and a small orifice will create the greatest drift hazard. This is because high pressure will result in a faster flow rate of the liquid, and a small orifice will restrict the flow, causing the liquid to be released at a higher velocity. The higher velocity of the liquid particles will make them more prone to drifting and being carried away by wind or air currents, increasing the potential for drift and causing a greater hazard.

    You must know the persistence of pesticides you apply to ornamental and turf areas, especially where:

    • A.

      Humans, pets, or other animals are present

    • B.

      Powder is applied

    • C.

      A garden is nearby

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    The persistence of pesticides is important to consider in areas where humans, pets, or other animals are present because they may come into contact with the pesticides and be exposed to their potentially harmful effects. Similarly, if powder is applied, it can easily be spread by wind or other means and may contaminate nearby gardens or areas. Therefore, all of the given options are valid reasons to be aware of the persistence of pesticides in ornamental and turf areas.

    The minimum period of time to keep children, adults, pets, and domestic animals from contact with sprayed turf is:

    • A.

      24 hours

    • B.

      48 hours

    • C.

      After washing the turf

    • D.

      Until the turf is dry

    Correct Answer
    D. Until the turf is dry
    Explanation
    The correct answer is "Until the turf is dry." This means that children, adults, pets, and domestic animals should not have contact with the sprayed turf until it is completely dry. This is important because the chemicals in the spray could be harmful if they come into contact with skin or are ingested. Waiting until the turf is dry ensures that any residue or chemicals have evaporated or been absorbed into the soil, reducing the risk of exposure.

    The control of pink and gray snow mold involves:

    • A.

      Heavy nitrogen fertilizer applications in late fall

    • B.

      Cutting the turf to a height lower than recommended

    • C.

      Allowing the turf to grow to a height of 4 inches before cold weather

    • D.

      The construction of snow barriers to minimize accumulation of snow in problem areas

    Correct Answer
    D. The construction of snow barriers to minimize accumulation of snow in problem areas
    Explanation
    The control of pink and gray snow mold involves the construction of snow barriers to minimize the accumulation of snow in problem areas. This is because snow mold thrives in areas where snow accumulates and remains for extended periods of time. By constructing snow barriers, the amount of snow that accumulates in these problem areas can be reduced, thereby reducing the risk of snow mold development. The other options, such as heavy nitrogen fertilizer applications, cutting the turf too low, or allowing the turf to grow excessively before cold weather, do not specifically address the control of snow mold.

    Factors that contribute to pesticide phytotoxicity are:

    • A.

      Uneven distribution of pesticides

    • B.

      High air temperatures

    • C.

      Excessive application rates of pesticides

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    The factors that contribute to pesticide phytotoxicity include uneven distribution of pesticides, high air temperatures, and excessive application rates of pesticides. These factors can all have negative effects on plants and can lead to phytotoxicity. Uneven distribution can result in some areas receiving too much pesticide, while others receive too little. High air temperatures can increase the volatility of pesticides, making them more likely to cause damage to plants. Excessive application rates can overwhelm plants and lead to toxicity. Therefore, all of these factors contribute to pesticide phytotoxicity.

    How many fluid ounces would be required on 4000 sq ft of turf with a label rate of 2 ounces per 1000 sq ft? How many teaspoons would be required for the 4000 sq ft? One fluid ounce equals 2 table­spoons, one tablespoon equals 3 teaspoons.

    • A.

      100 ounces or 200 teaspoons

    • B.

      8 ounces or 48 teaspoons

    • C.

      8 ounces or 20 teaspoons

    • D.

      15 ounces or 60 teaspoons

    Correct Answer
    B. 8 ounces or 48 teaspoons
    Explanation
    To calculate the amount of fluid ounces required for 4000 sq ft with a label rate of 2 ounces per 1000 sq ft, we can set up a proportion:2 ounces / 1000 sq ft = x ounces / 4000 sq ftx = (2 \* 4000) / 1000x = 8 ouncesNow, let's convert ounces to teaspoons. We know that 1 fluid ounce equals 2 tablespoons, and 1 tablespoon equals 3 teaspoons:8 ounces \* 2 tablespoons/ounce \* 3 teaspoons/tablespoon = 48 teaspoonsSo, for 4000 sq ft of turf, you would need 8 ounces of the product, which is equivalent to 48 teaspoons.

    The label requirement for treating billbugs on turf is 1.0 pounds of diazinon per 1000 sq ft when the total square footage is 9,400 sq ft. How many pounds of diazinon will be required?

    • A.

      15.6 pounds

    • B.

      13.8 pounds

    • C.

      12.3 pounds

    • D.

      9.4 pounds

    Correct Answer
    D. 9.4 pounds
    Explanation
    The correct answer is 9,400 sq ft and 9.4 pounds. This is because the label requirement is 1.0 pounds of diazinon per 1000 sq ft. So, to calculate the amount of diazinon required, we need to divide the total square footage (9,400 sq ft) by 1000 and then multiply it by 1.0. This gives us 9.4 pounds of diazinon required.

    • D.

      Common chickweed, henbit, field pennycress

    Correct Answer
    D. Common chickweed, henbit, field pennycress
    Explanation
    Winter annuals are weeds that germinate in the fall, overwinter, and complete their life cycle in the spring. The correct answer, "Common chickweed, henbit, field pennycress," consists of three weeds that are known to be winter annuals. Violets and shepherd's purse are not winter annuals, while large crabgrass and dandelions are summer annuals.

    Disease management in ornamentals can be improved by:

    • A.

      Dormant pruning, disease resistant varieties, bed rotation

    • B.

      Close plant spacing

    • C.

      Increasing water supply

    • D.

      All of the above

    Correct Answer
    A. Dormant pruning, disease resistant varieties, bed rotation
    Explanation
    Disease management in ornamentals can be improved by implementing several strategies. Dormant pruning helps remove infected or diseased branches, reducing the spread of diseases. Disease-resistant varieties are plants that have been bred to be less susceptible to certain diseases, reducing the need for chemical treatments. Bed rotation involves changing the location of ornamentals each year, which helps prevent the buildup of disease-causing organisms in the soil. Close plant spacing can create a favorable environment for disease development, so it is not a recommended strategy. Increasing water supply may actually promote the growth of certain diseases, so it is not an effective method for disease management. Therefore, the correct answer is dormant pruning, disease resistant varieties, and bed rotation.

      Cultural, chemical, mechanical, biological

    • C.

      Fertilizer, mowing, watering, dormatology

    • D.

      Identification, mowing, chemical, biological

    Correct Answer
    B. Cultural, chemical, mechanical, biological
    Explanation
    The correct answer is Cultural, chemical, mechanical, biological. These four methods are commonly used for weed control. Cultural methods involve practices such as crop rotation, proper irrigation, and mulching to prevent weed growth. Chemical methods involve the use of herbicides to kill or suppress weeds. Mechanical methods involve physically removing weeds through methods like hand-pulling or using tools like weed trimmers. Biological methods involve using natural enemies of weeds, such as insects or pathogens, to control their population. These four methods together provide a comprehensive approach to weed control.

    The presence of sod webworms in a turf area is relatively easy to determine by:

    • A.

      Drenching the suspected area with water to force the webworms to the surface.

    • B.

      Visual inspection of trees and shrubs in the suspected area.

    • C.

      Using a pyrethrum flushing agent to force the webworms to the surface.

    • D.

      Both A and B

    Correct Answer
    C. Using a pyrethrum flushing agent to force the webworms to the surface.
    Explanation
    The presence of sod webworms in a turf area can indeed be determined by using a pyrethrum-based flushing agent. This method involves applying the agent to the turf, which irritates the webworms and forces them to come to the surface, making them easy to spot. Drenching the area with water might not be as effective for this purpose. While visual inspection of trees and shrubs can help identify other pest issues, it's not the most effective method for detecting sod webworms in the turf. Therefore, the correct option is using a pyrethrum flushing agent.

    You are to apply a granular insecticide for sod webworm control. The recommended rate is 2 pounds of the granules per 1000 sq ft. How many pounds are needed for one acre? [Remember: 43,560 sq ft per acre]

    • A.

      308 pounds

    • B.

      87 pounds

    • C.

      130 pounds

    • D.

      218 pounds

    Correct Answer
    B. 87 pounds
    Explanation
    To find the number of pounds needed for one acre, we need to convert the recommended rate from square feet to acres. Since there are 43,560 square feet in one acre, we can divide the recommended rate of 2 pounds per 1000 square feet by 43.56 to get the rate per acre. This gives us a rate of approximately 0.046 pounds per acre. Multiplying this rate by 1 acre gives us the amount of insecticide needed, which is approximately 0.046 pounds. However, since we need a whole number of pounds, we round up to the nearest whole pound, which is 1 pound. Therefore, the correct answer is 87 pounds.

    The recommended method for controlling fire blight is:

    • A.

      Dormant pruning and antibiotic treatment

    • B.

      Summer pruning and antibiotic treatment

    • C.

      Summer pruning and dormant antibiotic treatment

    • D.

      Dormant pruning and antibiotic treatment at flowering

    Correct Answer
    D. Dormant pruning and antibiotic treatment at flowering
    Explanation
    Dormant pruning and antibiotic treatment at flowering is the recommended method for controlling fire blight. Fire blight is a bacterial disease that affects fruit trees, and dormant pruning helps remove infected branches before the bacteria can spread. Antibiotic treatment at flowering is also effective in controlling the disease as it targets the bacteria during their active growth phase. Summer pruning and dormant antibiotic treatment may not be as effective as they do not specifically target the bacteria at the right time.

    Control diplodia tip blight in pines by:

    • A.

      Winter pruning and summer bordeaux treatment

    • B.

      Summer pruning and two summer bordeaux treatments

    • C.

      Two bordeaux treatments in the spring

    • D.

      Pruning and burning stunned tips as they appear

    Correct Answer
    C. Two bordeaux treatments in the spring
    Explanation
    The correct answer is two bordeaux treatments in the spring. Bordeaux mixture is a fungicide that is commonly used to control diplodia tip blight in pines. It is most effective when applied in the spring, before the fungal infection becomes severe. By applying two treatments in the spring, it helps to prevent the spread and growth of the fungus, reducing the damage caused by diplodia tip blight. Pruning and burning stunned tips as they appear may help to remove infected plant material, but it is not as effective as using a fungicide like bordeaux mixture. Winter pruning and summer bordeaux treatment, as well as summer pruning and two summer bordeaux treatments, are not the most effective methods for controlling diplodia tip blight.

    Cultural control of bagworms can be effective if the bags are removed and destroyed by:

    • A.

      Spraying the bags during the winter

    • B.

      Spraying the bags in late summer

    • C.

      Hand picking the bags by mid May

    • D.

      Selecting resistant plants

    Correct Answer
    C. Hand picking the bags by mid May
    Explanation
    Hand picking the bags by mid May is an effective cultural control method for bagworms because it allows for the removal and destruction of the bags before the larvae inside have a chance to emerge and cause damage to plants. By removing the bags before mid May, the bagworm population can be significantly reduced, preventing further damage to plants. Spraying the bags during the winter or in late summer may not be as effective because the larvae are already inside the bags and may not be affected by the spray. Selecting resistant plants can help prevent bagworm infestations, but it is not a method for controlling existing infestations.

     Which type of herbicide application is most effective for annual grassy weeds?

    • A.

      Fall postemergence

    • B.

      Spring postemergence

    • C.

      Spring preemergence

    • D.

      Fall preemergence

    Correct Answer
    C. Spring preemergence
    Explanation
    Spring preemergence herbicide application is the most effective for annual grassy weeds because it targets the weeds before they emerge from the soil. By applying the herbicide in the spring, before the weeds have a chance to germinate and grow, it can prevent their growth altogether. This method is particularly effective for annual grassy weeds, as they tend to germinate and grow in the spring. Applying the herbicide in the fall may not be as effective because the weeds may have already germinated and established themselves by that time.

    Spider mites damage conifers by:

    • A.

      Eating needles

    • B.

      Sucking sap

    • C.

      Eating cambium layer

    • D.

      Girdling twigs

    Correct Answer
    B. Sucking sap
    Explanation
    Spider mites damage conifers by sucking sap. Spider mites are tiny pests that feed on the sap of plants, including conifers. They use their piercing mouthparts to extract the sap from the needles and stems of the conifers. This feeding behavior deprives the plants of essential nutrients and can weaken them, leading to stunted growth, yellowing or browning of needles, and even death in severe infestations. Therefore, sucking sap is the correct answer as it accurately describes the damage caused by spider mites to conifers.

    The best time to apply an insecticide to scale insects is in which stage of development?

    • A.

      Egg

    • B.

      Crawler

    • C.

      Pupa

    • D.

      Adult

    Correct Answer
    B. Crawler
    Explanation
    Scale insects go through several stages of development, including egg, crawler, pupa, and adult. The crawler stage is the best time to apply an insecticide because this is when the insects are most vulnerable and actively moving around. In this stage, the insects are small and mobile, making them easier to target and control with insecticides. Applying the insecticide during the crawler stage ensures that it reaches and kills the majority of the population, effectively managing the scale insect infestation.

    Leaf spot occurs during which of the following weather conditions?

    • A.

      Warm, dry weather

    • B.

      Cold, dry weather

    • C.

      Cool, wet weather

    • D.

      Weather has no effect

    Correct Answer
    C. Cool, wet weather
    Explanation
    Leaf spot is a common fungal disease that affects plants. It is caused by various types of fungi that thrive in cool, wet conditions. These fungi are most active when the weather is cool and there is an abundance of moisture, such as from rain or dew. In these conditions, the fungi can easily infect the leaves and cause the characteristic spots. Warm, dry weather is not conducive to the growth and spread of the fungi, so leaf spot is less likely to occur in these conditions. Cold, dry weather also does not provide the ideal conditions for the fungi to thrive.

    The ester form of 2,4-D is more hazardous than some other chemicals because its_______may cause it to drift onto nontarget plants

    Correct Answer
    Volatility, volatilization
    Explanation
    The ester form of 2,4-D is more hazardous than some other chemicals because its volatility may cause it to drift onto nontarget plants. Volatility refers to the tendency of a substance to vaporize or evaporate at a given temperature. In the case of the ester form of 2,4-D, its high volatility means that it is more likely to turn into a gas and be carried by air currents, potentially reaching and affecting plants that were not intended to be targeted. This makes it more hazardous as it can cause unintended damage to nontarget plants.

    A practical technique to reduce potential drift damage to ornamentals when spraying turf for weed control is:

    • A.

      Use a smaller nozzle with high pressure

    • B.

      Use a larger nozzle with low pressure

    • C.

      Apply the herbicide in very small droplets

    • D.

      Any of the above

    Correct Answer
    B. Use a larger nozzle with low pressure
    Explanation
    Using a larger nozzle with low pressure is a practical technique to reduce potential drift damage to ornamentals when spraying turf for weed control. This is because a larger nozzle produces larger droplets, which are less likely to be carried by the wind and drift onto ornamental plants. Additionally, using low pressure helps to reduce the force at which the herbicide is sprayed, further minimizing the potential for drift and damage to ornamentals.

    _________pesticides are most likely to cause harm to wildlife

    Correct Answer
    Accumulative, Accumulating
    Explanation
    Accumulative pesticides are likely to cause harm to wildlife because they can build up in the environment over time, leading to higher concentrations in the bodies of animals. This can result in toxic effects, such as reproductive problems, immune system suppression, and even death. Accumulative pesticides are persistent and do not break down easily, so they can continue to pose a threat to wildlife for long periods.

    To reduce drift of pesticides:

    • A.

      Use smaller droplets

    • B.

      Use dusts rather than sprays

    • C.

      Keep nozzles close to the target pest or site

    • D.

      All of the above

    Correct Answer
    C. Keep nozzles close to the target pest or site
    Explanation
    To reduce drift of pesticides, keeping nozzles close to the target pest or site is the most effective method. This ensures that the pesticides are applied directly to the intended area and minimizes the chances of them drifting away with wind or air currents. Using smaller droplets and dusts rather than sprays can also help reduce drift to some extent, but keeping the nozzles close to the target is the most important factor in preventing drift.

    Which of the following turf herbicides is an example of a selective, translocated, and post-emergence type?

    • A.

      Roundup

    • B.

      2,4-D

    • C.

      Dacthal

    • D.

      Paraquat

    Correct Answer
    B. 2,4-D
    Explanation
    2,4-D is an example of a selective, translocated, and post-emergence herbicide. Selective herbicides target specific types of plants while leaving others unharmed. Translocated herbicides are absorbed by the plant and move throughout its system, killing the entire plant. Post-emergence herbicides are applied to weeds after they have emerged from the soil. 2,4-D meets all of these criteria, making it the correct answer.

    The chance for drift will be increased by:

    • A.

      An over-application of pesticides

    • B.

      Using mist-like (fine) spray droplets

    • C.

      Both B and D

    • D.

      Vaporization of the pesticide

    Correct Answer
    C. Both B and D
    Explanation
    Both an over-application of pesticides and using mist-like (fine) spray droplets can increase the chance for drift. Over-application of pesticides can lead to excess spray that can easily be carried away by wind, causing drift. Mist-like spray droplets are smaller in size and can be easily carried by wind, increasing the chance for drift. Vaporization of the pesticide can also contribute to drift as it can turn into a gas and be carried away by wind. Therefore, both options B and D can increase the chance for drift.

    Which formulation is most likely to cause phytotoxic injury?

    • A.

      Emulsifiable concentrate

    • B.

      Wettable powder

    • C.

      Granular

    • D.

      Dust

    Correct Answer
    A. Emulsifiable concentrate
    Explanation
    Emulsifiable concentrate formulations are most likely to cause phytotoxic injury because they contain solvents that can directly damage plant tissues. These solvents help in the dispersion of the active ingredient in water, but they can also penetrate plant cells and disrupt their structure and function. In contrast, wettable powder, granular, and dust formulations do not typically contain solvents that can directly harm plants, making them less likely to cause phytotoxic injury.
