Belt, Altacor: these pesticides are in the same chemical class and are very effective on peach twig borer larvae.

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

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.
