Chandigarh: After floods damaging considerable tracts of paddy fields in Punjab, now two diseases sheath blight’ and ‘foot rot’ have attacked the crop in the state, which have the potential of adversely affecting crop yield if preventive measures are not taken at the earliest.

Punjab Agricultural University (PAU) have found the diseases attacking paddy fields in Ropar, Patiala, Ludhiana and Amritsar districts of the state on all varieties, with current weather conditions remaining favourable for spreading of these fungus diseases.

The incidence of sheath blight attack on paddy fields remained up to 20 per cent while incidence of foot rot disease found to be as high of 40 per cent.

“The intermittent rains provide conditions favourable for disease development. Both these diseases can have a negative impact on the crop yield if these are not controlled," PAU Plant Pathologist Department Head T S Thind said today.

“Sheath blight can be recognised from light green to straw coloured lesions with purple margins on the lower part of the leaf sheath near the water level. When weather conditions are favourable for the disease, it can spread to upper leaves and inflorescence thus affecting yield reaching panicle emergence stage,” said Thind.

Farm experts advised farmers to clean rice fields as pathogen can survive on grassy weeds.
