WEATHER BASED AGRO-ADVISORIES
Rice
· Heavy rains at maturity may leads to lodging of the crop. To control germination of grains on panicle spray 5% salt solution (50 g per liter of water).
· The threshed wet paddy grains should be sundried on tarpaulins.
· Prevailing weather conditions are congenial for incidence of grainspot disease in rice. To control, spray Propiconazole @ 1 ml or Carbandazim + Mancozeb @ 2.5 g or Tricyclozole + Tebuconazole @ 0.4 g per liter of water twice at 7-10 days interval.
· In case of incidence of panicle mite observed along with grain spot disease spray Spiromesifin @ 1 ml or Dicofol @ 5 ml or Profenophos @ 2 ml per liter of water in combination with fungicides recommended under grainspot disease twice at 7-10 days interval.
· Prevailing weather conditions are favorable for flare up of blast (leaf, neck and spikelet) disease in rice. To control, spray Isoprothiolane @ 1.5 ml or Kasugamycin @ 2.5 ml or Tricyclozole @ 0.5 g per litre of water twice at 7-10 days interval.
· Incidence of leaf folder was observed in rice. To control, spray Cartaphydrochloride @ 2 g or Clorantraniliprole @ 0.3 ml per liter of water.
· The probability of incidence of BPH would be more in late planted rice crop. To control, spary Acephate @ 1.5 g + Bufrofuzin @ 1.6 ml per liter of water. In case of severe infestation spray Dinotefuron @ 0.4 g or Paimitrozine @ 0.6 g or Ethiprol + Imidachloprid @ 0.25 g per litre of water twice at 7-10 days interval.
· Avoid spray of Chlorpyriphos, Profenophos, Synthetic Pairathroids in BPH infested fields.
Maize
· The optimum time for sowing of maize is 15th October to 15th November. It is recommended to sow the crop during clear weather situation (rain free) to ensure better germination.
· Under prevailing rainy situation postpone harvest of maize crop and take up harvesting during clear weather situation (rain free).
· In case of harvested maize crop, de-husk and go for shade drying.
Cotton
· Prevailing weather conditions are congenial for incidence of bacterial leaf spot and boll rot diseases in cotton. To control, spray Copper-Oxy-Chloride @ 30g and Plantamycin @ 2 g or Streptomycin @ 1 g per 10 litres of water or Mancozeb + Carbendazim @ 2.5 g per litre of water.
· Prevailing weather conditions are congenial for incidence of leaf spot diseases in cotton. To control, spray Mancozeb + Carbendazim @ 2.5 g per litre of water.
· Prevailing weather conditions are congenial for incidence of sucking pests in Cotton. If noticed, go for stem application with Monocrotophos and water in 1:4 ratio or Imidaclopridand water @ 1:20 ratio using soft brush on tender part of the stem at 40 and 60days after sowing.
· Incidence of Spodoptera is noticed in cotton. To control, spray Thiodicarb @ 1.5 g or Novoluron @ 1 ml per litre of water.
Redgram
· At present the crop is at bud initiation to flowering stage which is more favorable for incidence of maruca flower Webber. The larvae web the flower and cause damage to the crop. To control at initial stage, spray 0.5% NSKP or 5 ml neem oil / liter of water. Based on the severity, spray chlorpyriphos @ 2.0 ml + diclorovas @ 1.0 ml or flubendamide @ 0.2 ml or spinosad @ 0.3 ml or clorantraniliprol @0.3 ml per litre of water.
· Incidence of Spodoptera is noticed. To control, adopt the following IPM measures
- Arrange birds perches @ 20 per acre
- Spray 5% NSKPE (neem seed kernal powder extract) or Chlorpyriphos @ 2.5 ml or Acephate @ 1.5 g or Novoluron @ 1 ml or Thiodicarb @ 1.5 g or Indoxacarb @ 1.0 ml per litre of water.
Castor
· Prevailing weather conditions are congenial for the incidence of gray mold. To control, spray Carbendazim @ 1g or Propiconazole @ 1 ml per litre of water by wetting all the plant parts 6-8 hours before occurrence of rains and after 6-8 hours of cessation of rains as a prophylactic measure.
· Incidence of Spodoptera is noticed. To control, adopt the following IPM measures
- Arrange birds perches @ 10 per acre
- Spray Acephate @ 1.5 g or Novoluron @ 1 ml or 1.5 g Thiodicarb per litre of water.
Vegetables
· Prevailing weather conditions are congenial for incidence of sucking pests in Bhendi, Brinjal and Tomato crops. To control keep 10-20 sticky traps. If incidence is severe spray Dimethoate or Methyl Demeton or Fipronil @ 2 ml per litre of water.
· Weather conditions are favorable for incidence of fruit borer in Brinjal and Bhendi. To control, erect 40 pheromone traps per acre to trap female insect. If incidence is severe, spray Flubendamide @ 0.4 ml or Profenophos @ 2 ml per litre of water in Brinjal. Spray Thiodicarb @ 1 g or Novoluran @ 1 ml per liter of water in Bhendi.
· Prevailing weather conditions are favorable for incidence of flea beetle in Gourds. To control, spray Chlorophyrphos @ 2 ml per litre of water.
· Prevailing weather conditions are congenial for incidence of leaf spots diseases in vegetables. To prevent the incidence, spray Carbendazim @ 1 g or SAAF @ 2 ml perlitre of water.
Cattle and buffaloes
· Prevailing weather conditions are congenial for the occurrence of
- Ranikhet disease in poultry, ET,sheep pox and blue tongue in Sheep
- Hemorrhagic Septicemia, Foot and mouth disease in cattle and Buffaloes. To prevent the diseases, vaccinate the animals
