Part V: IPM Spray Programs

This section offers specific suggestions for pesticide use on apples, pears, peaches, nectarines, apricots, cherries, and plums. Remember that the pesticide label is the document that ultimately prescribes how a chemical can be used, and that labels can change. When applying a chemical, have a copy of the label in hand.

The pesticide recommendation tables in this section display two rates for each pesticide, based on two application methods. The first column (dilute rate/100 gal) shows the amount of formulated pesticide to be added to the spray tank for every 100 gallons of water. This rate assumes a total spray-mixture volume of 300 to 400 gallons per acre for apples, pears, and cherries and 300 gallons per acre for other stone fruits. The second column displays the recommended rate of formulated pesticide to be applied on a sprayed-acre basis regardless of the total amount of spray mixture. We recommend that at least 50 gallons per acre be applied in most situations and that at least 100 gallons per acre be applied for particularly serious situations, such as heavy mite populations, potentials for severe scab infection, and high probability of fruit damage from the the leafrollers and internal fruit feeders (e.g., Oriental fruit moth, codling moth). Note that the amount per sprayed acre is equivalent to spraying one acre of orchard if both sides of the tree are sprayed and two acres of orchard if alternate sides of the tree are sprayed.
