Uses of the biological insecticide Metarhizium anisopliae

Metarhizium anisopliae is a fungus-based organic insecticide. It is found freely in the soil and it is commonly found as a parasite in insects. 

When the spores of Metarhizium anisopliae come in contact with the target insect, they attach to their covering and Spores germinate when there is proper temperature and humidity. Their germinal tubes enter the insect’s body through the respiratory holes (spiracles), sensory organs and other soft parts.

This fungus increases itself by absorbing the physical food substances of the insect by making a fungal trap in the entire body of the insect. Metarhizium anisopliae produces spores even at less than 50% moisture. Because of this it works in all circumstances.

Metarhizium anisopliae is used for the control of beetles, white grubs, termites, caterpillars, semi-loopers, cutworms, mealybugs and aphids.

Method of use:

  • For soil application, Metarhizium anisopliae at the rate of 1 kg per acre mixed with about 75 kg of farm yard manure and should be used at the time of last ploughing.

  • For pest control in standing crops spray 1 kg per acre in 400-500 litres of water.
