Water in grub treatments immediately after application. During periods of drought, pre-treatment watering several hours or the day before application may be necessary to move the grubs into the contact zone. Keeping track of grub-infested areas may enable the management to reduce area treatments. Mapping is done by extensive smapling with a greens cup cutter and recording the presence or absence of grubs on a map of the area. Treating only mapped areas of grub activity reduces the areas treated and, therefore, the amount of pesticide used.
Japanese beetles are pests of northern and east central Alabama.
Grub treatments are the same as for other 1-year life cycle pests. Good penetration of grub controls into the soil is essential. Water before treatment if dry conditions exist, ans water after application. See label for amount of water to use when mixing sprays. DO NOT pre-water.
