Also, nematodes shouldn't be stored in hot vehicles, or left in spray tanks for long periods of time. Watering the insect-infested area before and after applying nematodes keeps the soil moist and helps move them deeper into the soil. Care should be taken not to soak the area because nematodes in too much water cannot infect. Exposure to UV light or very high temperatures can kill nematodes . Nematodes function best with soil temperatures between 60F and 93F .
Application is usually easy.
In most cases, there is no need for special application equipment. Hose-end sprayers, pump sprayers, and watering cans are effective applicators as well. Nematodes are even applied through irrigation systems on some crops. Check the label of the nematode species to use the best application method. Repeat applications if the insect is in the soil for a longer period of time.
