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.
