When should I put down Merit 0.5 Insecticide?


The application timing for Merit 0.5 G Insecticide Granules will depend on the insects you are targeting but typically most effective when applied prior to, or just after, egg lay. Please review the product label for more information on the target pest for your application.  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 and under normal circumstances, Merit 0.5G Granules will provide residual white grub control for 4 months or longer in the soil. This product should be applied with a drop-type and rotary-type spreader.
