Expert Advisory Details

Advisory from IMD Bihar

Monitoring of Brown Plant Hopper (BPH) in paddy crop is advised. This pest may be seen at the basal portion of the plant in the middle of the crop field. It is looking as mosquito type. If damage is more, spraying of Imidacloprid 17.8 % SC @ 1.0 ml / 3 lit of water is advised to save the crop. Gundhi bug may appear in early sown rice field during flowering to milky stage. It causes appreciable losses to crop during milky stage. As a result individual rice grain becomes white and chaffy. Apply Folidol dust@10-15 kg per hectare to control Gundhi bug in rice crop in the early morning or late evening.

Farmers are advised to apply 30 kg nitrogen/hectare in paddy crop.

RICE- Monitoring of gundhi bug is advised in early transplanted paddy crop, which is in milk stage. It causes appreciable damage during this stage. The nymph and adults of insect-pest suck the juice from the developing grains in the stage, causing incompletely filled panicles or panicle with empty grains causing them chaffy. Due to repugnant smell emitted from this pest, it could be easily identified in the field. If the number of pest exceeds ETL (Economic Threshold Limit) value, dusting of Folidol dust@10-15 kg per hectare is advised for suppressing the bug population in the crop field. The bunds and grasses around paddy crop may also be dusted. Farmers are advised to apply 30 kg nitrogen/hectare in paddy crop which reaches in panicle initiation stage and apply 40 kg/hectare nitrogen in late sown paddy crop which reaches in tillering stage.

PIGEON PEA- Farmers are advised to complete the sowing of pigeon pea crop as earliest. Pusa-9 and Sarad varieties are recommended.

GREEN GRAM- Monitoring is advised for yellow vein mosaic virus (YMV) disease in green gram and black gram. This disease is caused by white fly. If infestation is found, spraying of Imidacloprid @ 0.3ml/litre of water or Trizofos 40 EC @1 ml/litre of water are suggested to protect the crop. Affected plants are to be uprooted and destroyed before spray.

CAULIFLOWER- Nursery sowing of late varieties of cauliflower such as Maghi, Snoking, Pusa snoking-1, Pusa-2, Pusa snowball-16 and Pusa snowball K-1 is advised.Transplanting of mid duration varieties of cauliflower such as Pusaaghani, Pusi, Patna men, Pusa synthetic-1, Pusashubhra, Pusasarad, Pusamedhna, Kaasikuwari, and early snowball is advised. Monitoring of diamond back moth (DBM) in cauliflower is advised. The larva of insect-pest feeds on leaves makes bite holes and causes excessive defoliation mostly on the growing parts. Under severe damage, only network of veins remains left and head formation is rarely observed. If infestation is observed, spraying of Spinosad 1ml/4litres of water is advised.
