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).
Mode of action
The spores of this fungus when comes in contact with the cuticle (skin) of the pest insect, they germinate and grow directly through the cuticle to the inner body of their host. The fungus proliferates throughout the insect’s body, draining the insect of nutrients and eventually killing it.
Cut flowers, Ornamentals in greenhouses and Nurseries, Vegetables, Maize, Rice, Cotton, Cole crops and Plantation crops.
Tetranychus urticae (Two – spotted Spider Mite), Panonychus ulmi (European Red Mite), Byrobia rubrioculus (Brown Mite), Aculus schlectendali (Apple Rust Mite).
The product should be sprayed on growing plants using hand, ground or aerial spray equipment. It works best at temperatures between 22.C and 30.C and requires high humidity.
Frequency of application
Applications should be repeated at least once in a week for four weeks. For greenhouse pest problems, applications in every 10-15 days are recommended. All applications should be based on monitoring of pest populations.
Foliar spray: 2.5 kg / hectare in 500 litres of water i.e., 5 gm per litre of water. The spray volume depends on the crop canopy.
Drip and Sprinkler system: 5 gm / litre of water. The resultant solution after mixing should be filtered with appropriate filters to remove the extraneous particle if any before injecting this final solution into the drip/sprinkler mother tank.
