Developed Water Dispersible Powder (WDP) formulation of Bacillus thuringiensis var. kurstaki against Helicoverpa armigera (Hubner) by using 8 carriers, 2 dispersing agents and two wetting agents. One recipe was found more effective (LC50: 0.025%) compared to commercial formulation Halt 5%WP (LC50 : 0.043). (Pesticide Research Journal.18 (2): 179-182)
Developed a viable efficient sex pheromone trap for mass trapping of groundnut leaf miner, Aproaerema modicella Dev. Designed and modified sex pheromone trap based on the behaviour and return movements of leaf miner male moths. Wota- T trap (consists of an adaptor, basin to hold water and a lure holder with canopy with trapping area of 1584 cm2) was efficient in mass trapping of male moths of leaf miner. Among the various trapping materials tried, castor oil as glue or water mixed with kerosene was found equally better trapping 197 and 195 male moths/trap/day respectively. (International Pest Control, London 48(2): 83-85)
Developed an efficient trap for monitoring of the cowpea aphid, Aphis craccivora Koch in groundnut ecosystem. Based on the average aphid population trapped, cylindrical yellow sticky trap was found efficient recording higher population (220.1 aphids /week) compared to sticky trap (75.1 aphids /week).

Studied the compatibility of sex pheromones of Spodoptera litura (F.), Helicoverpa armigera (Hub.) and Aproaerema modicella in cotton and groundnut ecosystem. (Indian Journal of Plant Protection. 33 (1): 143-144)
Studied the effect of intercropping on the yield and yield parameters of groundnut. Groundnut + pigeonpea and groundnut + castor intercropping treatments were found significantly superior in respects of total production and monetary returns than sole cropping of groundnut. Intercropping has no significant effect on shelling per cent, sound mature kernels (SMK) (%) and oil content (%) of groundnut. (Indian Journal of Agricultural Sciences. 77 (8) : 515 – 518)
Developed module of Integrated Pest Management (IPM) in groundnut. Farmers achieved higher groundnut pod and haulm yield of 2416 and 3463 kg/ha, respectively with IPM module compared to their own practice (2050 kg/ha and 3114 kg/ha) due to the effective control of insect-pests and diseases. (Krishi Chayanika, 3: 21-22)
Studied the impact of farmer participatory assessment of integrated pest management (Indian Journal of Extension Education. 44 (3&4): 58-61)
Taken up studies on the development and validation of forewarning models for major insect pests of groundnut such as Spodoptera litura, leafhopper, Balclutha hortensis L. thrips, Caliothrips indicus Bagnell and Aphis craccivora Koch. Regression equations were worked out based on weather data and pest incidence during different seasons over years. The information will be useful for predicting pest occurrence for need based pest management strategy.

Conducted experiments on artificial defoliation simulating pest damage during different growth stages to assess the yield losses in groundnut. These studies will be useful for the development of Economic Threshold Levels (ETLs). (Indian Journal of Agricultural Sciences. 77 (9): 574 – 578; Journal of Oilseeds Research 24 (2): 283-285)
Developed an efficient sex pheromone trap for eggplant fruit and shoot borer, Leucinodes orbonalis Guennee. Wota- T trap developed by Pest Control India (PCI) (Pvt) Ltd., Mumbai, caught significantly higher number of male moths (21.49 mean male moths/ 3 nights/trap) compared to other traps. (Indian Journal of Entomology)
Studied the life- table of Caryedon serratus reared on three different hosts such as Bengal gram, tamarind and groundnut and at various temperatures such as 250C, 300C, 350C and 400C degrees centigrade. (Indian Journal of Entomology 70(3): 246-249 and Indian Journal of Agricultural Sciences 81 (6): 550–54)
Studied the effect of egg density on weight loss and adult emergence of Caryedon serratus in groundnut pods (one, two and three seeded) and kernels (bold and wrinkled). (Indian Journal of Agricultural Sciences 78 (5): 479-481; Indian Journal of Entomology 70 (2): 131-135).
Studied the relative efficacy of different imidacloprid schedules and new insecticides against sucking pests of groundnut
Identified sources of resistance of groundnut against leafhoppers, thrips and bruchid, Caryedon serratus (Abstracts of National Symposium on Recent Developments in the Management of Plant Genetic Resources)
Studied the factors affecting spinosad toxicity to the lesser grain borer, Rhyzopertha dominica (Conference of the IOBC/WPRS (OILB/SROP) Working Group on “Integrated Protection of Stored Products”)
