| Leaffooted plant bug on pomegranate with babies (nymphs) |
Q. Several months ago you answered my question as to what was affecting the loss of all my almonds in my almond trees. You said I should apply the insecticide Sevin for pest control. But when do I apply the Sevin? My almonds are doing well now but they always do well now and then later I see something ozzing out of the nuts and a yellowish design on the inside. Then the nuts drop from the tree. So when do I spray with this insecticide?
A. If I told you to apply Sevin insecticide I must have thought you had leaf footed plant bug in your almonds. My personal philosophy is to use pesticides as a last resort for insect control whenever possible. This would be the only reason I would recommend the use of a pesticide in almonds.
You would apply it when you see the insect present on the leaves. This insect has overwintered in yours or your neighbors landscape plants. I have seen them overwinter in our climate in these locations. When leaves emerge, this insect will begin feeding and laying eggs. The first thing you will see are herds of the immature called nymphs on the undersides of leaves. You might see some adults as well but the babies are much more numerous. You should start to see them around late April or early May so start looking then. When you see them, begin spraying immediately according to the label mixing rate. Wear protective clothing.
