*-PHI varies with crop and/or use

table continues below...

Earwigs: apply pesticides to the trunk and base of tree.

Grasshoppers, Mormon crickets: See Special Programs (http://jenny.tfrec.wsu.edu/eb0419/web/Special_Programs)

Leafrollers, Oriental fruit moth: to minimize the development of resistance to any unique class of insecticide products in the class should not be used against consecutive generations. Examples of pesticides in the same class are Delegate, Success, and Entrust (spinosyns, Group 5) and Belt and Altacor (diamides, Group 28). A sound resistance management program therefore requires the use of different classes of insecticide against consecutive generations.


Delegate, Success, Entrust and Bt: primarily or exclusively stomach poisons so complete coverage is very important for efficacy. Repeat applications of any product should be based on pest pressure and the efficacy of the initial treatments based on sampling.

Bacillus thuringiensis subsp. kurstaki: apply when warm weather is predicted for 3 or more days. Two or three applications per pest generation may be required to achieve adequate control.

Delegate, Entrust, Success: PHI is 14 d on apricot, 1 d for peach and nectarine, and 7 d on plum. Entrust is a spinosad formulation registered for organic production

Intrepid 2F: Some leafroller populations have developed resistance to methoxyfenozide so continued use may result in reduced control.

Sevin 4F: do not apply on blooming cover crops because of hazard to bees.

Success 2F: Some leafroller populations have developed resistance to spinosad products and repeated use of these products during the growing season could result in reduced levels of control.

*-PHI varies with crop and/or use

table continues below...

Peach twig borer: use the phenology model (available at http://das.wsu.edu) for optimum timing of sprays.

Peachtree borer: apply pesticides as a trunk spray, using a handgun directed at the trunk and soil at the base of the trees.

Shothole borer: Good sanitation (removing large wood pruning and wood piles from the orchard) is the best management tactic. Insecticides are only effective against adults. The second generation flight begins in late July or early August. Yellow sticky traps placed on orchard borders will detect activity of the adult beetles. Spraying the border trees (rows) with high water volumes will protect the remainder of the orchard in many situations where external sources are the primary problem.


Delegate, Success, Entrust and Bt: primarily or exclusively stomach poisons so complete coverage is very important for efficacy. Repeat applications of any product should be based on pest pressure and the efficacy of the initial treatments based on sampling.

Delegate, Entrust, Success: PHI is 14 d on apricot, 1 d for peach and nectarine, and 7 d on plum. Entrust is a spinosad formulation registered for organic production

Intrepid 2F: Some leafroller populations have developed resistance to methoxyfenozide so continued use may result in reduced control.

Peach Tree Borer pheromone: Peachtree borer pheromone, apply dispensers in late June or when the first moths are caught in pheromone traps. Place dispensers in upper half of canopy.

Success 2F: Some leafroller populations have developed resistance to spinosad products and repeated use of these products during the growing season could result in reduced levels of control.
