While paddy farmers are struggling to find a way out of the huge losses incurred by the ‘root-knot nematode’ disease that affected their nurseries in the district, case worms and blast diseases have also done their bit for the standing paddy crops in the district.
While the case worms hit paddy fields at several parts in Mandya, diseases such as ‘neck blast’ and ‘leaf blast’ have been affecting the paddy crops in Mandya and Mysore districts since the past few weeks. Researchers and plant pathologists at the Zonal Agricultural Research Station (ZARS), V.C. Farm, say that the diseases could have severe impacts on Mandya’s rice production this year.
Blast diseases have been noticed at a large area of paddy fields in several taluks in the district, M.P. Rajanna, Senior Rice Breeder and Head (Rice), V.C. Farm, told The Hindu on Sunday. “It was observed that a vast area of paddy fields in Mandya and Mysore district is was in the panicle emergence and grain filling stage. The symptoms of leaf and neck blast have already appeared in a few varieties such as MTU 1001, IR 64 and KCP-1,” Mr. Rajanna said.
Blast diseases are commonly observed especially during cloudy weather and light rain, H.M. Atheek ur Rehaman, Subject Matter Specialist at V.C. Farm (Agronomy), said. The symptoms of neck blast and leaf blast diseases have also been observed in Tumkur, Ramanagaram, Davangere, Chitradurga and a few other districts.
V.C. Farm noticed the outbreak of ‘root-knot nematode’ disease in K.R. Pet taluk recently. The disease had severely affected crop growth. Farmers should be very vigilant about their standing crops.
They should immediately initiate measures to tackle diseases as they could cause severe damage to the crop and yield, D.K. Siddegowda, Entomologist (Rice, V.C. Farm), said.
