PAU's expert's advice for sowing of cotton crop

Complete the sowing of cotton in the first fortnight 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, waste lands, 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 timely management of whitefly on these crops. Regular surveillance of whitefly on cotton should also be done. In situations, where Itsit emerges after first irrigation or with the rain shower, Stomp 30 EC @ 1.0 litre/acre can also be applied as post-emergence after first irrigation to cotton. Spray herbicide uniformly by dissolving in 200 litres of water. If some weeds emerge before the application of herbicide, those should be control by hoeing or interculture as stomp does not control germinated weeds. Give one hoeing/interculture about 45 days after sowing to control the weeds.
