Weather based Agromet-Advisories (for the period ending on 26th September, 2021)

Advisory based on advices received from the subject matter specialists of agromet-advisory committee:

  • Keeping in view of threat of COVID-19 spread farmers are advised to follow the government guidelines, personal hygiene, use mask, ensure hand washing with soap at reasonable interval, social distancing during picking of vegetables and other agricultural operation in all crops.
  • In present weather condition, field preparation should be started for rabi crops. Ploughing and planking should be done properly to conserve the moisture in the soil.
  • Keeping in view of rainfall during next days, farmers are advised to do proper arrangement for drainage in all vegetables, pulse, maize and nurseries of the crops. Farmers are also advised not to do any type of spray in the crops.
  • Present weather conditions are suitable for sowing of early pea. Recommended cultivars: - Pusa Pragati, Pusa Shree. Seed should be treated with fungicides,Captan or Thiram @ 2 gm/ kilogram and after that with crop-specific Rhizobium  A solution of jaggary and water after boiling should be allowed to cool down and then seeds along with Rhizobium should be thoroughly mixed. The mixture should be allowed to dry in a shade. It is highly recommended that the treated seeds should be sown after 24 hours of treatment.
  • Field preparation should be done for early mustard- Pusa Sarson-25, Pusa Sarson-26, Pusa Sarson-28, Pusa Agrni, Pusa Taraka, Pusa Mahak and start sowing in already prepared fields.
  • Sowing of carrot can be done in raised bed. Recommended cultivars: - Pusa Rudhira. Seed rate-0 kg/ acre. Application of FYM, potash and phosphorus fertilizer is recommended. Seed treatment with Captan @ 2 gm per kilogram is advised. Now day’s machine for sowing of carrot is available. Farmers can do sowing by machine because it reduces the seed rate, improve the quality of produces and increase the yield.
  • In present weather conditions termites may damage crops and vegetables in the present weather. Farmers are advised to spray Chlorpyriphos 20 EC @ 4 ml/litre of water with irrigation water.
  • Keeping present weather in view, farmers are advised to monitor their fields regularly. Spray of Imidacloprid 17.8 % SC@ 1.0 ml / 3 lit. of water is recommended against white flies and other sucking pests in all crop and vegetables when sky remains clear.
  • Present weather conditions are highly favorable for infection of blast disease in rice. Monitoring at 2-3 days interval is advised. Early symptoms include development of eye shaped spot in the leaf sheath with light centre and dark boundaries. At later stage these spots coalesce to form big spots.
  • In present weather conditions, false smut may appear in paddy in present weather conditions. Symptoms include increase in grains size with brown colored fungus inside. Spraying of Blitox 50 @ 500 grams per acre at 10 days interval (2-3 times) is advised.
  • In present weather condition, constant monitoring for brown plant hopper(BPH) in paddy field is advised. Farmers are advised to enter into the middle of the crop field and see mosquito like insect at the basal portion of the plant. If insect population is above ETL than spray of imidacloprid @ 0.3 ml per litre of water is advised when sky remains clear.
  • In paddy crop constant monitoring of stem borer by using pheromone traps 4-6 per acre is advised, If insect population is above ETL, broadcast Cartap 4% granules @ 10 kg/acre for effective control.
  • In vegetables (brinjal, tomato etc) constant monitoring of borers by using pheromone traps 4-6 per acre is advised, If insect population is above ETL than spraying of Spinosad 1.0 ml/4 litre of water is advised against fruit borer and diamond back moth in cauliflower and cabbage when sky remains clear.
  • Sowing of sarson saag- Pusa saag-1; Radish- Summer long, long chetaki; Spinach- All green; Coriander- pant Haritama or other hybrids should be done on raised bed.
  • In present weather conditions, rouging of viral infested crop should be done in chilli and tomato. Infected plants should be uprooted and buried in the soil. If infection is more than spray of imidacloprid @ 0.3 ml per litre of water is advised for control the vector when sky remains clear.
  • Keeping present weather in view, farmers are advised to use light trap to keep a check on pest population. This causesless damage to useful insects. For making a light trap, a bulb should be fixed above a tumbler (either plastic or tin) having a mixture of water and few drops of any insecticide. The insects get attracted towards the light, fall in the solution and die.
