Weather based Agromet Advisories (for the period ending on 24th September, 2017)

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


1.    Mostly paddy crop in panicle initiation stage which is 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.

2.   At this time paddy crop in panicle initiation stage. Farmers are advised to monitor crop regularly, if population of stem borer is above ETL than broadcastof Cartap 4% granules or carbofuran 3% G @ 10 kg/acre for effective control is recommended. Farmers are advised to install pest specific pheromone traps @ 3-4/acre in the paddy fields for monitoring of stem borer.

3.   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 spray of Imidacloprid 17.8 % SC@ 1.0 ml / 3 lit or fenobucarb 50 EC @ 1 ml/ litre or buprofezin 25 EC @ 2 ml/ litre of water is recommended.

4.      Farmers are advised to transplant green onion seedling in the prepared fields. Nurseries should be prepared in raised bed.

5.      Planting of early potato is advised to the farmers. The crop matures in 80-90 days. Recommended varieties: - Kufri Badshah, Kufri Surya. Thereafter, sowing of other rabi crop such as late wheat can be taken up.

6.    Field preparation should be started for earlypea and arrangement for quality seeds should be done (cultivars- Pusa pragati, Pant matar-3, Arkil etc.).

7.      Sowing of carrot can be done in raised bed. Recommended cultivars: - Pusa Rudhira. Seed rate-4.0 kg/ acre. Application of FYM and phosphorus fertilizer is recommended. Seed treatment with Captan @ 2 gm per kilogram is advised. For good germination moisture should be optimum in the soil.

8.   In vegetables (brinjal, chilli, cauliflower, cabbage, tomato etc), for monitoring of borer insect, farmers are advised to use pheromone trap @ 3-4/acre. If insect population is above ETL than, spraying of Spinosad 1.0 ml/4 litre of water is advised against fruit borer, diamond back moth.

9.   This is suitable time for sowing of Sarson Saag- Pusa Saag-1; Bathua- Pusa Bathua-1; Radish- Japani White, Hill queen, French  Radish; Spinach- All Green, Pusa Bharti; Fenugreek-Pusa Kasuri;Coriander- Pant Haritama, Hybrids; Turnip- Pusa Swati, Local Red variety.

10.  Monitoring of cucurbitaceous crops against attack of fruit fly should be done by the use of ‘Methyl Eugenol trap. Protection of cucurbitaceous crops against fruit fly by use of bait trap (mixing juggary 10 % with Malathion 0.1 % and putting at different corners of the field) is advised.

11.  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.

12.  Constant monitoring of ladyfinger, brinjal and chilli crop against attack of mite, jassid and hopper is advised. To control mite, spraying of phosmite @ 2 ml per litre of water is advised while spraying of Dimethoate 30 EC @ 2 ml/liter of water is advised against jassid and hopper.

13.  Field preparation should be started for sowing of early mustard. Arrangement of quality seeds should be done, recommended cultivars- Pusa Sarson-25, Pusa Sarson-26, Pusa Agrni, Pusa Taraka, Pusa Mahak.

14.  Termites may damage crops and vegetables in the present weather. Farmers are advised to spray Chlorpyriphos 20 EC @ 4 ml/litre of water.

15.  Farmers are advised to use light trap to keep a check on pest population. This causes less 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 Rogor or kerosene oil. The insects get attracted towards the light, fall in the solution and die.

16.  Marigold plantation should be done in present weather conditions.
