Cotton sowing ends in the first fortnight of this month

Cotton: Complete the sowing of cotton 15th of this month and follow clean cultivation, destroy Kanghi buti (Sida sp.) and Peeli buti (Abutilon sp.) which act as collateral host of cotton leaf curl virus.

  • Eradicate the weeds like kanghi buti, peeli buti, puth kanda etc. growing on field bunds, wastelands, road side and irrigation channels/canals to avoid further spread of whitefly to cotton fields.
  • Whitefly also attacks other alternate host crops like brinjal, potato, tomato, okra, moong, mash and guar. Regular surveillance should be done for the timely management of whitefly on these crops.
  • In situations, where It emerges after first irrigation or with the rain shower, Stomp 30 EC @ 1.0 liter/acre can also be applied as post-emergence after first irrigation to cotton. Spray herbicide uniformly by dissolving in 200 liters of water. If some weeds emerge before the application of herbicide, those should be controlled by hoeing or interculture as stomp does not control germinated weeds. Give one hoeing/intercultural about 45 days after sowing to control the weeds.
