Item Chemical control of thrips stenchaetothrips biformis Bagnall using synthetic pyrethroids in rice nursery(Kerala Agricultural University, 1988) Reghunath, P; Premila, K S; Thomas Biju Mathew; Nandakumar, CItem Compatibility of insecticides and fungicides on the mortality of Nilaparvata lugens (Stall.) and on the inhibition of rhizoctonia solani kuhn.(Kerala Agricultural University, 1993) Babu, K; Reghunath, P; Mohandas, N; Wilson, K IThe compatibility of insecticides and fungicides commonly used for the control of insect pest and disease of rice was studied in the laboratory using Nilaparvata lugens and Rhizocfonia sdanl as lest organisms. By fixing the proportion of constituents in the insecticidal, fungicidal mixture judiciously, it may be possible to reduce the field dose of insecticide as there was synergism in the insecticidal activities of lower dose of quinalphos when combined with different doses of fungicides. The fungicidal effectsof the three fungicides were signifcantly altered when combined with insecticides. Combination with fungicides showed an antagonistic effect at higher levels of captofol, ediphenphosand carbendazim, while at lower concentrations there was enhancement of fungicidal effect.Item Eco-friendly management of important sucking pests of chilli(Department of Agricultural Entomology, College of Agriculture, Vellayani, 1999) Santhosh Kumar, T; Reghunath, PItem Efficiency of paraquat in relation to its time of application(Kerala Agricultural University, 1985) Reghunath, P
