Abstract:

The study was conducted during kharif 2014 at College of Agriculture, Indore under All India Coordinated Cotton Improvement Project in Randomized Block Design (RBD) with eight treatments and three replications on Bt cotton hybrid NCS 927, sown on 27th July with 0.6x0.6 m spacing. All the recommended agronomical practices were adopted. Treatments were planned for alternate use of two insecticides during six sprays. The spraying was done at 10 days interval with 500 litre water per hectare, using knapsack sprayer fitted with a duromist nozzle. These treatments were prepared as T1- Imidacloprid (70%WG) @ 24.5 gai/ha & Oxydmeton methyl (25%EC) @ 250 gai/ha, T2- Thiaclorprid (21.7%SC) @ 30 gai/ha & Dimethoate (30%EC) @ 250 gai/ha, T3- Imidacloprid (17.8%SL) @ 25 gai/ha & Acephate (75%SP) @ 250 gai/ha, T4- Imidacloprid (30.5%SC) @ 26.25 gai/ha & Thiamethoxam (25%WG) @ 37.5 gai/ha, T5- Spiromesifen (22.9%SC) @ 144 gai/ha & Deltamethrin (2.8%EC) @ 15 gai/ha, T6-Fipronil (5%SC) @ 100 gai/ha & Lambdacyhalothrin (4.9%EC) @ 15 gai/ha, T7- Acetamiprid (20%SP) @ 30 gai/ha & Difenthiuran (50%WP) @ 300 gai/ha and T8- Untreated check. All the treatments Exhibited a significant reduction in jassid population over untreated check. Treatment T6- Fipronil (5%SC) @ 100 gai/ha & Lambdacyhalothrin (4.9%EC) @ 15 gai/ha showed least pest population in each spray and expressed no significant difference with T5- Spiromesifen (22.9%SC) @ 144 gai/ha & Deltamethrin (2.8%EC) @ 15 gai/ha. Similarly the overall jassid population reduction was recorded highest in treatment T6 (80.56%) followed by T5 (74.88%) and other treatments in which T1- Imidacloprid (70%WG) @ 24.5 gai/ha & Oxydmeton methyl (25%EC) @ 250 gai/ha (61.21%) showed least population reduction. Similar trend of efficacy was observed against aphid where treatment T6 showed least pest population in each spray and expressed no significant difference with T5. Again T6 showed highest aphid population reduction (80.56%) and followed with T5 (74.88%).
