An outbreak of sterility mosaic infection has been spotted on the tur crop in some districts of Karnataka. The infection is caused by an insect attack and humid weather is conducive for its spread. Agrimet has advised farmers to uproot the infected plant and spray insecticide to control its spread. Karnataka is the second largest producer of tur in the country after Maharashtra. Farmers in the state have sown the crop over 878,000 ha as of Sep 7, down 26% from last year.
