How are the nematodes handled in preparation for application?
It is very important that the nematodes are living organisms so they must be kept out of direct sunlight and kept cool until they are applied. They should be stored in the refrigerator or a cold box at 50 to 65 F. from time of receipt until they are being prepared for application. Nematodes will settle to the bottom of applicator tanks so it is very important to agitate or shake the tank every 15 to 20 minutes to assure that the nematodes are uniformly suspended in the water. Commercial sprayers having by-pass pressure regulation provide very good agitation of the water and do not require shaking or further agitation. Nematodes are very hardy and can safely tolerate 100 to 150 pounds of pressure, but they can be damaged if pumped through filter screens that have mesh sizes smaller than 30. For best results, remove all filter screens. Nematodes can drown, so it is important to make sure that the entire volume of spray in a tank is applied without delay. Nematodes can safely tolerate a p
