Paecilomyces fumosoroseus Isaria fumosorosea is an entomopathogenic fungus, formerly known as Paecilomyces fumosoroseus. It shows promise as a biological pesticide with an extensive host range.

When a conidium or blastospore of Isaria fumosorosea lands on a suitable host, it produces enzymes to penetrate the insect’s cuticle. A germ tube then grows into the haemocoel [4] and the fungus proliferates inside the insect’s body. The fungus can also enter through the spiracles, the mouth or the anal opening. The mycelia spread in the haemolymph and tissues, eventually emerging from the insect and producing conidia. Mortality of the insect has been ascribed to the drainage of its nutrients, the destruction of its tissues and the release of toxins.

Isaria fumosorosea has been used to control insect pests of plants grown for the production of cut flowers, ornamentals growing in greenhouses and nurseries, vegetable and cole crops, cotton, maize, rice and plantation crops.

It has also been found to reduce the development and spread of powdery mildew, Sphaerotheca fuliginea, on cucumbers

A comparison made between several entomopathogenic hyphomycetes showed that Paecilomyces fumosoroseus provided more effective control of the cabbage-heart caterpillar, Crocidolomia binotalis, than did either Beauveria bassiana or Metarhizium anisopliae

Target Pest: Tea mosquito bug (Helopeltis thievors), Mealy Bug, Grasshopper, White Fly, Aphid, Beetle, Caterpillar, Thrips etc.

Time & condition of the spray: High humidity and low temperature (below 35ºC) will enhance the efficacy of Bio-protector. Do not spray any chemical after this. Bio-protector can be used after 7 days of chemical spray.
