- Lawn and Garden Blend Nematodes is an organic pest control that is lethal to pests yet safe for plants, people and pets. It contains the beneficial nematodes Steinernema carpocapsae and Heterorhabditis bacteriophora. S. carpocapsae is relatively sedentary and tends to remain near the soil surface to 'ambush' its host. They work best in soil temperatures over 70F.
- A complete life cycle takes 12 to 15 days at room temperature. The beneficial nematodes enter the insect pest through body openings. Once inside they reproduce and release a symbiotic bacterium which is toxic to the host. The pests are killed within a few days and a second generation of infective juvenile nematodes exit the host and begin the cycle again. Use as part of your IPM program.
- Entomopathogenic nematodes are supplied as infective juveniles, which are easily applied as a soil drench and kill insects within 24 to 48 hours. Not all nematodes are alike. They specialize in which pests they attack and kill and are effective at different temperatures. Feel safe with this chemical free pest control.
- Beneficial nematodes come in two forms. Sponges that are pre-inoculated with infective juveniles in quantities of 1 million, 6 million and 24 million. Generally, in a greenhouse setting, apply these beneficial nematodes at a rate of 1 million per 1,000 sq. ft. The sponge product has a completely unique application rate as the bacterial level is much higher because they are produced in vivo.
Trays that contain 50 million or 250 million. Release every 2-3 weeks at a rate of 50 million/1100 sq. ft. or every 4-6 weeks at a rate of 50 million/550 sq. ft. Use 30-50 gallons of water/1000 sq. ft. for applications onto soil or growing media.
- Apply nematodes with a sprayer, injector, hose end sprayer or even a watering can. Plug trays can be dipped in a nematode solution. If using an injector, set the dilution to 1:100. It is important to remove all filters or screens (50 mesh or finer) in any spray lines so that the nematodes can pass through unimpeded and undamaged. Keep spray pressure below 300 psi. For every square foot you will need .66 gallons of water as the carrier. Saturate soil or potting media to a depth of 2". See Nematode Tech Sheet for further information. Broad spectrum pest control without harmful pesticides. Shipped fresh, quality guaranteed.
