Malathion is also effective against immature scale insects (crawler stage) and catfacing insects (stink bugs and plant bugs) and will help control oriental fruit moths and lesser peach tree borers. You can reduce fungicide sprays by applying fewer cover sprays during periods of dry weather. While fungicide sprays are necessary to grow peaches in the Deep South, much of the real protection from these diseases will come from removing and destroying the inoculum (or seed-producing structures) of these diseases.
