Steinernema feltiae (NemaShield Sf Invivo)

Controls:

Steinernema feltiae (NemaShield Sf Invivo) is a beneficial nematode that is effective against certain nursery and greenhouse pests, especially fungus gnats. It is also used to combat thrips pupae in the soil. The nematodes enter the insect host through body openings. They multiply within the host and release a symbiotic bacterium whose toxin kills the fungus gnats. The larvae are killed in one to two days by blood poisoning. More than one generation of nematodes may develop in dead host insects in the media. The infective juveniles then exit the dead body and search for new hosts to infect. Best known for their ability to control fungus gnats, soil-dwelling stages of thrips.

Application Rate Recommendations for Steinernema feltiae (NemaShield Sf Invivo):

• Preventative: 10 million nematodes per 1000 square feet.
• Moderate Infestation: 20 million nematodes per 1000 square feet.
• Heavy Infestation: 50 million nematodes per 1000 square feet.

How-To Use Steinernema feltiae (NemaShield Sf Invivo) For Best Results:

• For best results, check nematode viability before application. Place a small amount of the product in a small clear container or petri dish. Add one or two drops of room-temperature water. Wait a few minutes and look for actively moving nematodes. They have a slight J-shaped curvature at the end of their bodies.
• Use a black background and a hand lens or field microscope to observe the nematodes.
• Dead nematodes will be straight and still
• Check nematode viability before application.
• Apply immediately after receiving them.
• If you must store the nematodes, store them in a refrigerator at 38-42° F.
• Avoid placing them in a small refrigerator where they may freeze.
• Check the expiration date on the package for the length of time it can be stored.
• Treat as soon as possible (two or three days) after sticking cuttings, planting plugs, or starting seeds.

Features & Benefits:

• Effective against certain nursery and greenhouse pests, especially fungus gnats.
• Can be used to combat thrips pupae in the soil.
• No restricted entry interval (REI), an added bonus in propagation houses.
• No possibility that the target pest will develop resistance.
• No adverse effects on non-target organisms have been observed in field studies.
