The tolerant and intolerant crop lists may have changed
The use sites may have changed
It’s the law.
All of the above

Correct Answer

A. All of the above

Explanation

Reading the label each time you use a Plant Protection Product is important because the directions for use, rates, tolerant and intolerant crop lists, and use sites may have changed. Additionally, it is also a legal requirement to read the label before using any such product.

What is the #1 reason people describe their pre-emergent program as a failure?

It costs too much
It injures the crop
They don’t get good weed control because they applied it to existing weeds.
It’s more expensive than hand weeding.

Correct Answer

A. They don’t get good weed control because they applied it to existing weeds.

Explanation

The #1 reason people describe their pre-emergent program as a failure is because they applied it to existing weeds. Pre-emergent herbicides are designed to prevent the growth of weeds by inhibiting seed germination. If the herbicide is applied after the weeds have already emerged, it will not be effective in controlling them. Therefore, it is important to apply pre-emergent herbicides before the weeds have a chance to germinate in order to achieve optimal weed control.

Which of the following should be used to manage weeds?

Pre-Emergent herbicide Sprays
Pre-Emergent herbicide Granules
Non-Selective Post-Emergent herbicide sprays
Selective Post-Emergent herbicide sprays
Hand weeding
All of the above

Correct Answer

A. All of the above

Explanation

All of the above options should be used to manage weeds. Pre-emergent herbicide sprays and granules are used to prevent weed seeds from germinating. Non-selective post-emergent herbicide sprays are used to kill existing weeds. Selective post-emergent herbicide sprays target specific types of weeds. Hand weeding is a manual method of removing weeds. Using all of these methods together can effectively manage and control weeds in a given area.

What is the best source of information about a herbicide’s mode of action?

MSDS
Herbicide Resistance Action Committee website
Label
USA Today

Correct Answer

A. Herbicide Resistance Action Committee website

Explanation

The best source of information about a herbicide's mode of action is the Herbicide Resistance Action Committee website. This website is dedicated to providing accurate and up-to-date information about herbicides and their modes of action. It is specifically focused on herbicide resistance and provides comprehensive details about how herbicides work, their target weeds, and any potential resistance issues. The website is a reliable source for professionals in the field of herbicide use and can provide valuable information for understanding the mode of action of specific herbicides.

When choosing a broad spectrum granular herbicide, which of the following properties should you consider.

Does it control both broadleaf and grass weeds.
Are the most problematic weeds you face on the label?
Are most of my crops tolerant (do they appear on the tolerant list)
All of the above

Correct Answer

A. All of the above

Explanation

When choosing a broad spectrum granular herbicide, it is important to consider all of the above properties. A broad spectrum herbicide should be able to control both broadleaf and grass weeds, as these are the most common types of weeds that can cause damage to crops. Additionally, it is crucial to ensure that the most problematic weeds faced by the farmer are listed on the label of the herbicide, indicating that it is effective against those specific weeds. Lastly, it is essential to check if the crops being grown are tolerant to the herbicide, as using a herbicide that is not crop-tolerant can result in crop damage.

If herbicide A costs a grower $100/bag and its supposed to be applied at 2 bags to the acre, but herbicide B costs $75/bag and must be applied at 3 bags to the acre, which has the higher cost in use?

Herbicide A
Herbicide B

Correct Answer

A. Herbicide B

Explanation

Herbicide B has the higher cost in use because even though the cost per bag is lower compared to herbicide A, it needs to be applied at 3 bags per acre. This means that for every acre, the grower would need to spend $225 (3 bags x $75 per bag) on herbicide B, whereas for herbicide A, the cost would be $200 (2 bags x $100 per bag). Therefore, herbicide B has a higher cost in use.

Which is/are reason(s) to use Granular formulations of Pre-Emergent Herbicides

Granular formulations are, generally, less likely to cause Phytotoxicity to crop plants than sprayable formulations of the same active ingredient.
Granular herbicides give growers the option to use active ingredients that might not be useful if they came only in a sprayable formulation
Granular herbicides are less expensive to apply
Granular herbicides frequently contain more than one active ingredient so that they control many different weed species.
A, B, D
B, C, D
All of the above

Correct Answer

A. A, B, D

Explanation

Granular formulations of pre-emergent herbicides are preferred for several reasons. Firstly, they are less likely to cause phytotoxicity to crop plants compared to sprayable formulations of the same active ingredient. This ensures that the herbicide effectively targets weeds without harming the crops. Secondly, granular herbicides provide growers with the flexibility to use active ingredients that may not be available in sprayable formulations. This allows for a wider range of options to control different weed species. Lastly, granular herbicides are generally less expensive to apply, making them a cost-effective choice for weed management. Therefore, options A, B, and D are the reasons to use granular formulations of pre-emergent herbicides.

Which are reasons to use Sprayable formulations of Pre-Emergent Herbicides?

Sprayable pre-emergent herbicides may kill seedlings that granular pre-emergent herbicides with the same active ingredient would not kill.
Sprayable Pre-emergent herbicides are less expensive to apply
Sprayable Pre-emergent herbicides can be used to increase the number of active ingredients beyond what’s available in granular pre-emergent herbicides alone.
Sprayable Pre-emergent herbicides are known to give longer control than Granular herbicides.
A, B, C
A, C, D
All of the above

Correct Answer

A. A, B, C

Explanation

Sprayable formulations of pre-emergent herbicides are preferred for several reasons. Firstly, they have the ability to kill seedlings that granular pre-emergent herbicides with the same active ingredient may not be able to kill. This ensures more effective control of weeds. Secondly, sprayable pre-emergent herbicides are less expensive to apply, making them a cost-effective option for weed management. Lastly, sprayable formulations allow for the addition of multiple active ingredients, which can enhance their effectiveness compared to granular herbicides alone. Therefore, the correct answer includes options A, B, and C.
