What are some tips for using biological control nematodes?
1) Use them as soon as possible after they arrive. Remember, the nematodes must be alive to work and they die off during prolonged storage. 2) Store them in a cool place until use. Most species should be refrigerated, but some need higher temperatures. Check with the manufacturer for the optimal storage temperature. The nematodes are in a dormant state while they are cool. If they get warm they will become more active and die quicker. Also, do not let them freeze as that can kill them. 3) Do not expose them to heat or sunlight. Heat kills nematodes rapidly. Nematodes are also sensitive to U.V. light from the sun. 4) Early morning or evening is usually the best time to apply them. During light rain can also be a good time. These are times when it is cool and light intensity is low. 5) Water the soil before and after you apply nematodes. Nematodes need water to move and survive. The water will also help get the nematodes into the ground out of the sunlight, and to where the insects are.
