This Agricultural University was named after the illustrious son of Vidarbha Dr. Panjabrao (alias Bhausaheb) Deshmukh, who was the Minister for Agriculture,Govt. of India. The jurisdiction of this university is spread over the eleven districts of Vidarbha. According to the University Act 1983 (of the Government of Maharashtra), the University is entrusted with the responsibility of agricultural education, research and extension education alongwith breeder and foundation seed programme. The University has its main campus at Akola. The instructional programmes at main campus are spread over in 5 Colleges namely, College of Agriculture, College of Agricultural Engineering & Technology, College of Forestry, College of Horticulture and Post Graduate Institute. At this campus 4 degree programmes namely B.Sc.(Agri.) B.Sc. (Hort.), B.Sc. (Forestry) and B.Tech. (Ag. Engg.) , two Master’s Degree Programmes viz. M.Sc.(Agri.) and M.Tech. (Agri.Engg.) and Doctoral Degree Programmes in the faculties of Agriculture and Agril. Engineering are offered. The University has its sub-campus at Nagpur with constituent College, College of Agriculture which offers B.Sc.(Agri.) and M.Sc.(Agri.) degree programmes. The Nagpur Campus is accomplished with a garden, surrounded by its natural beauty and a well established Zoo which attract the general public and visitors to the city. A separate botanic Garden is being maintained on 22 hectares with a green house for the benefit of research workers. In addition there are 2 affiliated grant-in-aid colleges and 14 private non-grant-in-aid colleges under the umbrella of this University A Central Research Station is situated at the main Campus which caters to the need of research projects undertaken by Crop Scientists of the principle crops of the region are Cotton, Sorghum, Oilseeds and Pulses.

    The present investigation entitled “Evaluation of ready mix insecticides against bollworm complex of cotton” was conducted on the farm of Department of Agricultural Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, during kharif season of 2016-17. The experiment was laid in randomized block design with seven treatments, replicated thrice. The treatments included were, Pyriproxifen 5% + Fenpropathrin 1.5% EC, Cypermethrin 3% + Quinalphos 20% EC, Novaluron 5.25% + Indoxacarb 4.5% SC, Thiamethoxam 12.6% + Lambda cyhalothrin 9.5% ZC, Indoxacarb 14.5% + Acetamiprid 7.7% SC and Profenofos 40% + Cypermethrin 4% EC along with untreated control. Three sprays of treatments were applied at 15 days interval to study the comparative efficacy of ready mix insecticides against bollworm complex of cotton. The observations were recorded at interval of 7 and 14 days after spraying. Similarly, the observations on natural enemies i.e. predators like, lady bird beetles, chrysoperla and spiders were also recorded. Besides, pink bollworm damage and larval population were recorded at 125 and 140 days after germination. Also open boll damage due to bollworm complex was observed at each picking. Seed cotton yield data was also recorded from each of the net plot to find out most economical and effective treatment for the management of bollworm complex of cotton. The application of Indoxacarb 14.5% + Acetamiprid 7.7% SC proved effective in recording minimum green fruiting bodies damage, which was closely followed by Profenofos 40% + Cypermethrin 4% EC, Novaluron 5.25% + Indoxacarb 4.5% SC and Thiamethoxam 12.6% + Lambda cyhalothrin 9.5% ZC. The data of present studies revealed non significant effect of different treatments on the population of natural enemies as well as the incidence of pink bollworm in the green bolls. Significantly, minimum open boll damage due to bollworms at harvest was recorded in the insecticidal treatment Indoxacarb 14.5% + Acetamiprid 7.7% SC which was followed by Profenofos 40% + Cypermethrin 4% EC, Novaluron 5.25% + Indoxacarb 4.5% SC, Thiamethoxam 12.6% + Lambda cyhalothrin 9.5% ZC and Cypermethrin 3% + Quinalphos 20% EC. Whereas, the treatment of Pyriproxifen 5% + Fenpropathrin 1.5% EC proved relatively less effective in this respect. Similarly, the yield data indicated that all the treatments recorded significant increase in the seed cotton yield compared to control plot. The highest seed cotton yield was recorded in the plot sprayed with Indoxacarb 14.5% + Acetamiprid 7.7% SC, which was closely followed by Profenofos 40% + Cypermethrin 4% EC, Novaluron 5.25% + Indoxacarb 4.5% SC Thiamethoxam 12.6% + Lambda cyhalothrin 9.5% ZC and Cypermethrin 3% + Quinalphos 20% EC. On the basis of economics, Profenofos 40% + Cypermethrin 4% EC proved to be the most economically viable treatment followed by Thiamethoxam 12.6% + Lambda cyhalothrin 9.5% ZC, Cypermethrin 3% + Quinalphos 20% EC, Indoxacarb 14.5% + Acetamiprid 7.7% SC, Novaluron 5.25% + Indoxacarb 4.5% SC and Pyriproxifen 5% + Fenpropathrin 1.5% EC. The present finding indicates that these insecticides can be suitably incorporated in an integrated management programme of bollworm complex in cotton.
