    Have any of you used Merit 75 WSP on Pecan Trees for Honeydew drop and have you applied it as a drench around the base?

    Nope, but Orthene works well cuz of its systemic properties.

    If the pecans are for edible use, you probably want to use a contact foliar spray.

    Plus, use an insecticide designed for "sucking" insects.

    Best your local land-grant university. They probably offer a "fruit/nut tree spraying schedule".

    Zinc is an important micronutrient you may also want to incorporate with the insecticide spray for pecans.

    Make sure you charge plenty.

    Also -- if you're just spraying for aphids on the foliage, you're merely fixing a cometic problem or limiting the amount of honeydew droppings on cars and decks. Aphids will not harm the tree.

    Case borers are a different story.

    Bottom line: contact your local extension office. Good luck, american.
