Let us know, Reason for outbreak of white grub in the fields

13/05/2022Posted on

  • In the Kharif season, there is an outbreak of white grub in the crops and fields.

  • The reason for its outbreak is the raw cow dung used in the empty fields during summer.

  • The cow dung that is used is not fully decomposed.

  • Many harmful insects and fungi are found in this dung, which is the reason for the attack of white grub.

  • The white grub definitely lays eggs on such a dung heap and when the cow dung is broadcast in the field, the white grub starts damaging the crops by going inside of the soil.

  • To avoid the damage of this pest, use only after decomposing the dung completely or use the decomposer after dung manure has been broadcasted in the empty field.

How to protect our crops from White Grubs

22/04/2019Posted on

White Grub management is a challenge for farmers, a severe attack has the potential of damaging 80 to 100% of the crop. A minuscule count of 2 to 14 grubs is enough to damage 64.7% of the crop.

Life cycle:-

1. After the lash of first rains, adult white grub comes out of the pupa stage and for the next month, it starts laying eggs 8 inches below soil level.

2. Next 3-4 weeks the gestation period sets in and the eggs grow to form larvae.

3. This larvae stage is most damaging for the crop as the larvae feed on the nutrients available in soil and crop for the next 4 to 5 months and just before the onset of incremental temperatures they once again attain the pupa stage.

White grubs management:-How to control

Chemical control:- Soil application of fenpropathrin 10% EC 10% EC @ 500ml per acre, fipronil 40 + imidacloprid 40% WG   @100 Gm/acre OR chlorpyrifos 20% EC @ 500 ml/acre.

Biological control:-  Apply Matarizum spp. @ 1kg/acre and Beauveria+Matarizum spp. @ 2kg/acre. Fungal formulation along with  first dose of fertilizers.

Mechanical control:- Use a light trap.

26/07/2018Posted on

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.
