Significant Weather Features (IMD)
- Dense fog observed at isolated places over West Bengal and Bihar; Moderate fog at isolated places over Delhi, Uttar Pradesh, Bihar, Assam & Meghalaya, Tripura and Odisha.
- A series of Western Disturbances is likely to move across the northern most parts of India during the forecast period. Isolated to scattered precipitation is likely over Western Himalayan region. Likely amplification of an easterly wave may cause further rise in night minimum temperatures over major parts of India. Thus cold wave conditions are not likely to occur except Punjab. Scattered to fairly widespread thundershowers are likely over south peninsula on 6th & 7th February.

- Rabi crop: For chemical weed control in wheat, spray isoproturon (75WP) @ 70 gm + 2,4D (80WP) @ 50 gm or clodinafop @ 24 g (10WP)or 16 g (15 WP) per kanal after 35-40 days of sowing i.e. 2-3 leaf stage of weed. After 2-3 days of clodinafop spray, apply 2,4-D @50 gm/Kanal. Use 30 litres of water for making a solution for one hectare.
- Thinning and weeding is recommended in timely sown mustard crop. For control of aphid in mustard crop. If insect population above ETL than spraying of Rogar or Quinalphos @ 2.0 ml\litre water is recommended.
- In wheat crop, if symptoms of termite are appear than application of mixture of 20 kg sand with Chlorpyriphos 20 EC @ 2.0 litre should be done in evening hours and subsequent irrigation is recommended.In areas where symptoms of yellow rust are appearing in the wheat crop in the form of yellow powder/stripes on the leaves, then the farmers are advised to spray the fungicides with the appearance of the symptoms.These are tilt (Propiconazole) 25 EC/folicure (Tebuconazole) 25 EC/bayletan 25 WP @0.1% i.e. 30ml or 30 g per 30 litres of water per kanal and repeat the spray after 15 days interval.
- Keeping in view of relative humidity farmers are advised for monitoring of mustard crop against attack of white rust.
