Abstract:
The field trials were carried out at A.N.D.U.A.T. Crop Research Station, Masodha Ayodhya, during kharif 2019 and 2020 to evaluate the efficacy of four combination modules/treatments consisting of three insecticides Chlorantraniliprole 20% SC, Cartap hydrochloride 50% SC and Triflumezopyrim 10% SC, one commercial neem formulation - Neemazal and two oils - Neem and Eucalyptus oil procured from IIRR, Hyderabad (Telangana) were compared along with untreated control (only water spray). There were significant differences in dead heart damage among the treatments. All insecticides treatment module recorded the lowest mean damage of white ears 1.3% when compared to 28.8% in untreated control. Among other treatments, neemazal, eucalyptus oil and cartap hydrochloride combination showed lowest mean infestation of 4.1% DH. Among modules, all insecticides module was found to be the best with 1.3% mean white ear damage followed by neemazal, eucalyptus oil and cartap hydrochloride module with 4.1% WE. All insecticides module was the most effective treatment showing mean leaf damage of 2.45% followed by treatment with neemazl, Eucalyptus oil and cartap hydrochloride (4.95% DL) when compared to untreated control (17.2% DL). All insecticides combination was the most effective treatment of Green leafhopper showing mean population of 3.0 followed by neeamazal, eucalyptus oil and cartap hydrochloride combination (17.7)) and were superior to control (61.7 hoppers/10 hills). All insecticides treatment Chlorantraniliprole, Cartap hydrochloride, Triflumezopyrim recorded the highest grain yield of 3260 kg/ha with 237.1% increase over control followed by neemazal, neem oil and cartap hydrochloride with 2350 kg/ha (143.01% IOC). All the treatments were significantly superior to control plot which showed a yield of 967 kg/ha. All insecticides combination minimized the yield loss in basmati rice.
