    Pansies have a higher demand for Boron and Iron than Geraniums

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Pansies have a higher demand for boron and iron compared to geraniums. This means that pansies require more of these nutrients in order to grow and thrive. Boron is important for cell division and carbohydrate metabolism, while iron is necessary for chlorophyll production and overall plant health. Therefore, it is true that pansies have a higher demand for boron and iron than geraniums.

  • 3. 

    Which facts are TRUE regarding Plantex 17-5-19 Poinsettia Feed

    • A.

      Iron is chelated with DTPA

    • B.

      The magnesium level is elevated

      Sufficient Molybdenum is added if fertigated constantly at 300ppm

    • D.

      All of the above are true

    • E.

      All of the above are false

    Correct Answer
    D. All of the above are true
    Explanation
    The given correct answer is "All of the above are true." This means that all three statements mentioned in the question are true. Iron is chelated with DTPA in Plantex 17-5-19 Poinsettia Feed, the magnesium level is elevated, and sufficient Molybdenum is added if fertigated constantly at 300ppm.

    Plantex 24-8-16 Foliage should be use in hot weather for Garden mums

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Plantex 24-8-16 Foliage should not be used in hot weather for Garden mums. This is because the high nitrogen content in the fertilizer can promote excessive leaf growth, making the plants more susceptible to heat stress. In hot weather, it is better to use a fertilizer with a lower nitrogen content and a higher phosphorus and potassium content, which will help the plants to develop stronger roots and improve their overall heat tolerance.

  • 5. 

    What is/are the greatest feature(s) of Plantex fertilizer(s)?

    • A.

      High solubility and superior micro package

    • B.

      High EC levels

    • C.

      Concentrations of Ca & Mg

    • D.

      Plastic bag

    • E.

      Sheilah Graham

    Correct Answer
    A. High solubility and superior micro package
    Explanation
    The greatest features of Plantex fertilizer(s) are high solubility and superior micro package. This means that the fertilizer can dissolve easily in water, making it readily available for plants to absorb. Additionally, the superior micro package indicates that the fertilizer contains a balanced blend of essential micronutrients, providing plants with all the necessary elements for healthy growth and development.

    Poinsettias require Calcium for growth from start to finish.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Poinsettias require calcium for growth because calcium is an essential nutrient for plant development. It helps in cell wall formation, root development, and overall plant structure. Calcium deficiency can lead to stunted growth, weak stems, and leaf deformation in poinsettias. Therefore, providing an adequate supply of calcium is necessary for the healthy growth and development of poinsettias.

    Rate this question:

  • 7. 

    Mums and Poinsettias have the folowing characteristics:

    • A.

      Both need higher levels of Boron

    • B.

      Both need higher levels of Molybdenum

    • C.

      Both are heavy feeders

    • D.

      All of the above

    • E.

      None of the above

    Correct Answer
    C. Both are heavy feeders
    Explanation
    Both mums and poinsettias are heavy feeders, meaning they require a significant amount of nutrients to thrive. This suggests that they have a high nutrient demand and may require frequent fertilization or a nutrient-rich growing medium. The other characteristics mentioned, such as the need for higher levels of boron and molybdenum, are not relevant to the question as they are not included in the answer.

    Rate this question:

  • 8. 

    Pansies which show clubbing are a result of?

    • A.

      High EC levels

    • B.

      High Calcium levels

    • C.

      High Nitrate levels

    • D.

      Low Boron levels

    • E.

      None of the above

    Correct Answer
    D. Low Boron levels
    Explanation
    Pansies that show clubbing are a result of low boron levels. Boron is an essential micronutrient for plant growth and development. It plays a crucial role in cell wall formation and stability. When boron levels are insufficient, it can lead to abnormalities in cell division and elongation, resulting in clubbing or distortion of plant tissues. Therefore, low boron levels can cause pansies to exhibit clubbing symptoms.

    Plantex Solutions 19-2-19 can be used on Pansies to help correct Iron deficiencies.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Plantex Solutions 19-2-19 is a fertilizer that contains a high concentration of iron. Iron deficiency is a common problem in pansies, causing yellowing of leaves and poor growth. By using Plantex Solutions 19-2-19, which is specifically formulated to correct iron deficiencies, the plants can receive the necessary iron nutrients to thrive and overcome this issue. Therefore, the statement is true.
