Common Fruit Tree Chemicals for Control of Insects and Disease

Common Fruit Tree Insect and Disease Problems and There Control

With many fruit trees blooming and preparing to set fruit, now is the time to be spraying fungicide to eliminate fruit problems, in the future. Many people around the parish have blueberries, mayhaws, plums, Muscadines, blackberries, apples, figs, peaches and pears planted around their homes for fruit production. It is important to spray fungicides during the bloom period to reduce the transmission of disease by insects and other means of disease transmission. Fungicide will not affect your pollination by bee and other pollinators. This is why you wait until petal fall to start using pesticides.

Below are some examples of some simplified spray schedules for the home owner to use during fruit production. You, as a producer, need to remember to follow the label directions on the chemical you are using because the label is the law.

Spray Schedule for following fruits:

Insecticides Fungicides

Plum/peaches Malathion 57%EC Captan

Carbaryl (Sevin 50%) Fungonil
