About this deal
For ornamentals under cover, spray onto soil around plant roots and after growing media application, the treated area should be lightly irrigated from above to wash the nematodes into the growing media. Whilst the application of Beneficial Nematodes is easy, the correct handling of the product and timing of the application is critical to its success. But the 7 million active units in each container will hunt down, penetrate, and kill fungus gnat larvae. They are completely compatible with beneficial insects such as ladybugs, lacewings, and praying mantids and do not harm earthworms.
Adults are able to find their way from outside into growing areas through gaps in protection, and can continually re-infest in this way. Beneficial Nematodes can be applied as a preventative treatment (before damage is noticed), throughout the year.
Plant Parasitic Nematodes have a stylet or spear at their head end, rather like a hypodermic syringe, which is used to pierce plant cells and then suck out fluids from within the cells. The effectiveness may be improved by adding a wetting agent and try to apply them in high humidity conditions for foliar applications.
Steinernema carpocapsae (Rhabditida: Steinernematidae) as a biological control agent against the fungus gnat Bradysia agrestis (Diptera: Sciaridae) in propogation houses. miles) helps break up the life cycle and eventually controls fungus gnat infestations by feeding on larvae and pupae. Remove the sponge from the kit and you will notice a light brown patch on it , those are the nematodes. This solution can be sprayed on the substrate or mixed into the water container of a aero or hydro system.No, for example fungus gnat nematodes can be applied to a single plant pot with a minimal fungus gnat infestation to stamp it out early.
