Control of white grubs in Soybean and Groundnut

Symptoms of damage:

The grubs feed roots. Grubs feed on fine rootlets, resulting in pale wilted plants, dying in patches.

Management of White grubs:-

Bio-Control:- Soil application- For soil insect pest like White Grubs,Termite, Agrotis species etc Mix 2.0 kg to 4.0 kg Metarhizium anisopliae with 50 kg of well decomposed fym/compost/field soil and broadcast in the field of 1 acre at the time of field preparation or in standing crop. Foliar spray – Mix 2.0 kg Metarhizium anisopliae, in 150 – 200 litre of water for spray on insect pest in the standing crop of 1 acre.
Spray should be undertaken as a community approach and should be repeated after every rainfall till the middle of July.
Spraying the trees close to the field with Chlorpyriphos 20 EC @ 2 ml/lit of water soon after first monsoon showers for 3-4 days in the late evening hours kills the adult beetles and reduces root grub infestation.
Seed treatment with chlorpyriphos 20 EC ( 6.5 to 12.5 ml/kg seed) is found effective.
In case of severe infestation apply Carbofuran 3% @ 10 kg/ Acre or Chlorpyrifos 20% EC @ 500 ml/acre or Phorate 10% G @ 10 kg/ha.
