1 Residual life of this material is short; extend effectiveness by combining with 1/2 rate of 2. Available for nectarines by 24(c) label in Virginia and West Virginia.

2 PC and C require control in limited areas. Consult the spray-to-harvest interval when selecting chemicals for application.

3 Sevin application is likely to result in increase in mites. Eliminate blooming weeds in order to protect bees. See note on Sevin XLR PLUS on p. 65.

4 Use the higher rate for TSM.

5 Although summer applications of pyrethroids are not recommended, they are the most effective materials for the control of SB.  Additional pyrethroiods are listed under Peach first cover.
