With both states asking growers to take remedial steps to prevent damage, whitefly infestation has come as major blow to farmers at a time when they had already faced huge financial loss when wheat crop got damage due to inclement weather conditions early this year.
In Punjab, whitefly attack on cotton crop even assumed political overtones as opposition Congress has sought CBI probe into the purchase of "spurious" insecticides for the cotton crop, leading to heavy loss to growers.
Total area under cotton in Punjab is about 4.50 lakh hectares with crop being grown in Bathinda, Abohar (Fazilka), Muktsar, Ferozepur and Mansa.
"Maximum impact of whitefly attack is seen in Abohar, Fazilka and Muktsar districts," the minister said adding that surveys have been launched to assess the damage to cotton crop due to whitefly.

"At about 6,000 acres of area have witnessed 100 per cent loss because of whitefly attack," said the state agriculture minister.
Punjab Agriculture Commissioner B S Sidhu said the widespread attack of whitefly was last witnessed way back in the year 1977 when heavy crop damage was seen on cotton in the state.
In Haryana, the situation is no better. An official of Haryana Agriculture department said that more than 80 per cent of 5.80 lakh hectares of area have witnessed pest attack in 12 districts including Sirsa, Hisar of the state.
Farm experts have advised growers that late sown crop are at greater risk for whitefly attack on cotton while high temperature and scanty rainfall situations aggravate the severity of the pest.
