Paecilomyces fumosoroseus, is considered a very promising biological pesticide due to its extensive host range which includes insects in over 25 different families, including the diamondback moth (Plutella xyllostella), Russian wheat aphid (Diuraphis noxia), silver leaf whitefly (Bemisia argentifolii) and wide range of mites (Spotted Spider Mite, Red Mite, Brown Mite, and Rust Mite).
When P. fumosorosea lands on a suitable host, it produces enzymes to penetrate the insects cuticle. A germ tube then grows into the bug and the fungus proliferates inside the insect’s body. The fungus can also enter through the spiracles themouth or the anal opening The mycelia spread in the circulatory system and tissues, eventually emerging from the insect and producing conida. Mortality of the insect has been ascribed to the drainage of its nutrients, the destruction of its tissues and the release of toxin
Dextrose carrier eliminates need to pre-dilute and filter. Add 5-10 grams per gallon of H20. Spray until run-off. Good coverage essential.
