Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola was established on 20th October, 1969 with its head-quarter at Akola. 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.

    EVALUATION OF VARIOUS MODULES AGAINST MAJOR PESTS OF OKRA.

    A field experiment entitled “Evaluation of various modules against major pests of okra: Field and simulation study” was conducted during Summer and kharif season of 2014-15 and 2015-16 at the Chilli and Vegetable Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (MS.).An experiment was laid in randomized block design consisting of eight modules viz., M1 (fully organic), M2, M3 and M4 (Chemical module with sequential use of insecticides), M5, M6 and M7 (IPM based module having ST, Soil application, YST and sequential use of chemical insecticides) and untreated module M8 to find out effective modules against major pests and its effect on natural enemies and also to study the abundance of major pests and predators during both the seasons and incidence of YMV in various modules and their economics. The results revealed that Module M6 and M4 were found most effective in reducing the population of leafhopper, whitefly, mites, shoot and fruit borer and incidence of yellow vein mosaic and in obtaining higher yield of okra fruits. However module M7 was significantly superior for arresting the population of aphids. The population of thrips was significantly reduced in module M6 and M5. All modules were found equal in maintaining predator population on summer and kharif season on okra indicating safety to natural enemies. Peak incidence of sucking pests (aphid, leafhopper, whitefly, thrips and mites) fruit borer and predators (LBB, Chrysoperla and Spider) was observed on okra from 9th April to 20th May (15-20th MW) and 2nd Sept to 7th Oct. (35- 40th MW) during summer 2014-15 and kharif season 2015-16, respectively. The module M6 followed by M4 and M5 were found significantly most effective in recording minimum incidence of YMV transmitted by whitefly at 60 to 95 DAS. The module M2 was found to be the least effective and at par with M7 and M3 in recording the minimum incidence of YMV. The module M4 followed by M2 and M6 were proved most economical by registering higher ICBR and NMR. However highest first rank NMR and third higher rank of ICBR recorded in module M6 which is twice more NMR than in module M2. Hence out of all module tested in present investigation module M6 was found IPM based most effective and economical against all major pests and YMV disease of okra. Maximum incidence of YMV (i.e. 10.90% and 22.22% ) was observed during 14th to 20th May (20th MW) and 1st to 22th Oct (40-43rd MW ) preceding the incidence of whitefly ( i.e. 5.71-6.86 and 6.54 to 6.88 whitefly/leaf ) during 18-19th MW and 37-38th MW in summer and kharif season. Yellow Sticky Trap at 15 cm height above the crop canopy was found most suitable for trapping maximum number of adults sucking pests (aphid, leafhopper, thrips and whitefly) during both summer and kharif seasons. Amongst the different chemicals tested in laboratory against leafhopperA.biguttulla biguttula., the treatment with thiamethoxam 25 WG @ 0.2g/Lproved most effective in recording highest (1649.94) persistence toxicity followed by cypermethrin 25 EC @ 0.4ml (933.26), dimethoate 30EC @ 2ml/L (833.28) and lambda cyhalothrin 5 EC @1ml/L (633.28) PT values, respectively. Overall among various modules module M6 (ST, SA, YST, Cyper, Tria, Feno, Ace+Spir) was found significantly most effective and economical followed by module M5 (SA, YST, Thia, Fenpo, Lamb, Tria+Dico) and M4 (Tria, Fenv, Qin+Spir, Fenpo, Lamb ) in minimizing the all sucking pests, shoot and fruit borer infestation, yellow vein mosaic diseases and in obtaining the highest ICBR and net monitoring return.
