    Where do Fungus Gnats cause the most damage?

    • Young cuttings

    • 1st transplant

    • Flowers

    Correct Answer
    A. Young cuttings
    Explanation
    Fungus gnats cause the most damage to young cuttings. This is because the larvae of fungus gnats feed on the roots of plants, which can lead to stunted growth, root rot, and even death. Young cuttings have delicate and vulnerable root systems, making them an ideal target for these pests. Additionally, the presence of fungus gnats can also attract other harmful insects and diseases, further exacerbating the damage caused to the young cuttings.

    Which mite feeding injury resembles a nutrition deficiency?

    • Two spotted mite

    • Lewis mite

    • Cyclamen mite

    • Vegi mite

    Correct Answer
    A. Lewis mite
    Explanation
    The Lewis mite feeding injury resembles a nutrition deficiency because these mites feed on plant sap, which can result in yellowing and discoloration of the leaves. This can be mistaken for a nutrition deficiency because the plant may not be receiving the necessary nutrients from the damaged leaves.

    • All of the above

    Correct Answer
    A. Flagship
    Explanation
    Flagship belongs to class A4 MoA insecticide because it is mentioned alongside Orthene and Duraguard, which are also listed as options. Therefore, since all three products are mentioned, it can be inferred that all of them belong to class A4 MoA insecticide.

    • Avid

    • Floramite

    • Judo

    • A & C

    • All of the above

    Correct Answer
    A. A & C
    Explanation
    Avid and Judo have shown activity on Whiteflies. This means that these two miticides have been proven to be effective in controlling or eliminating whiteflies. Floramite, on the other hand, may not have shown the same level of activity on whiteflies. Therefore, the correct answer is A & C, which means Avid and Judo have shown activity on whiteflies.

    Correct Answer
    A. Erwinia carotovora

It infects the roots and causes them to decay, leading to root cutting. Water deficiency, Thielaviopsis basicola, and Pepsicola versus cocacola are not associated with root cutting in the given context.

This fungus is commonly known as gray mold and it affects a wide range of plants, causing decay and rot. The V shaped lesions with a yellow margin are characteristic symptoms of Botrytis cinerea infection, making it the correct answer to the question.

Therefore, the correct answer is Alternaria alternata, as it is a common leaf spot disease on Poinsettia.
