Beauveria is a biological insecticide based on a selective strain of naturalitty- occurring entomopathogenic fungus Beauveria bassiana.
Mode of Action
The spore of the fungus when comes in contact with the cuticle (skin) of the target pest insect in germinates and grows directly through the spiracle in the cuticle into the inner body of the host. The fungus by taking nutrients from the insect proliferates and colonizes the entire insect and thus drains the insect of nutrients and the infected insects eventually dies.
Method of Application
Foliar Spray (Borer & Cutworm): Mix Beauveria 3 liters or 4 kg. / ha in 500 liters of water (i.e., 6 ml or 8 gm per liter of water). The product should be sprayed on growing plants using hand. Ground or aerial equipment targeting the insects. The spray volume depends upon the crop canopy.
Soil Application (for root grubs): Mix Beauveria 3 liters or 4 kg. / ha in 500 liters of water (i.e., 6 ml or 8 gm per liter of water). Beauveria can be sprinkled around the root zone and incorporated into the soil either mechanically or through profuse watering of the plant roots. Alternatively, at the recommended rate can be mixed with 1000 kgs of organic fertilizer or field soil and can be applied uniformly.
Drip System: Beauveria can be mixed W 6ml or 8 gm/ liter of water. After filtering it can be incorporated into the soil through the drip irrigation system during the pre or post plant stage.
