Merit 75 water soluble packet (WSP) is a liquid insecticide concentrate which can be used at very low rates and applied as a foliar spray, soil broadcast spray, soil injection or soil drench to control grubs, weevils, and other soil and turf inhabiting pests. Soil applications are taken up by plant, ornamental, and tree roots into twigs, stems, and foliage. Merit 75 WSP includes detailed instructions for application to turfgrass, ornamentals, trees, shrubs, flowers, groundcovers, and in and around commercial or residential buildings. Most applications of Merit 75 WSP require the use of a one or two gallon pressurized sprayer. There are 4 x 1.6 oz water soluble packets in each envelope.
Merit 75 Water Soluble Packet (WSP) attacks the nervous system in insects and prevents normal transmission of nerve impulses. This mode of action results in disruption of normal behavior; treated insects stop feeding, do not reproduce and eventually die. Merit 75 Water Soluble Packet (WSP) is most effective when applied prior to, or just after, egg lay. In most cases, adult emergence occurs in early summer, often after significant rainfall or irrigation, followed by mating and egg laying. This usually continues for four to six weeks. Under normal circumstances, Merit 75 Water Soluble Packet (WSP) will provide residual white grub control for four months or longer in turf.
Target pests: Ground and ornamental pests including Aphids, grubs and Chinch Bugs. See label for complete list.
