Management of White Grub in Groundnut
The white grub is an important soil pest, which causes severe damage to the groundnut. The larvae feed on decaying vegetables in early stage but damages roots during later phase. Although damage occurs in the patches and often leaving gaps and severely attacked entire field may devastated. Therefore, follow proper management practices as follows:
Management: • Follow regular pruning of the trees present around the fields. • After first heavy rain, the adult beetles feeding on leaves of Babul, Ber, Drumstick, and Neem need to be removed by shaking the branches and destroying it. • Spray Quinalphos 25 EC@ 20 ml in 10 lit of water on these trees present around the fields. • Summer ploughing may help in reducing their population. • Install light traps and destroy the beetles, which are attracted by light trap. • Seed treatment with Chlorpyriphos 20 EC @ 25 ml or Thiamethoxam 30 FS @ 10 g per kg of seed before sowing should be done. Use these treated seed for sowing after shade drying of 3 hours. • Apply Bouveria bassiana or Metarhizium anisopliae, fungus base powder (5 kg/ha) along with castor cake (300 kg/ha) in soil before sowing as well as drenching of the same powders (40 g/ 10 lit of water) in row after 30 days. • In standing crop, apply Chlorpyriphos 20 EC 4 lit/ ha through drip irrigation method or apply Phorate 10 G @ 10 kg/ha in soil.
