Current responsibilities:

  • Investigations on shoot bug and maize stripe virus in sorghum
  • Development of crop management options for key production constraints in target millets production ecologies.
  • Promotion of sorghum cultivation in rice-fallows and millets cultivation in non traditional areas of India.
  • Development of Integrated Pest Management technologies for millet crops.

Recent 3 major contributions:

  • Identified the mechanisms of resistance for shoot bug in sorghum: The high quantities of polyphenols and chlorophyll imparted tolerance to shoot bug nymphs and its adults population.
  • Antibiosis mechanism played a major role in reducing the shoot bug nymphs and its adult population. Total polyphenols and chlorophyll present in sorghum genotypes acted as defense mechanisms which are integral part of antibiosis to develop resistance to shoot bug.
  • Developed the cost-effective Integrated Pest Management (IPM) technology for the shoot fly, stem borer and shoot bug. Sorghum seed (resistant cv. CSV 15) treated with imidacloprid @14 ml/ kg of seed, sprayed the neem oil @ 5 % at 10 days after germination, applied Carbofuran 3 G granules @ 15 kg/ha in whorls at one month after germination and sprayed methyl demeton 25 EC @ 0.07 % at two months after germination reduced the incidence.
  • IPM technology was found cost effective i.e. by investment of one rupee, farmer could able to reap the profit of Rs. 2.80 (C : B = 1: 2.8) (net returns of Rs. 43,100/ha).
  • Disseminated the sorghum cost-effective technologies (IPM based plant protection, zero-tillage, dual purpose, production etc.) in rice-fallows of Andhra Pradesh resulted in the productivity of six tonnes per hectare. This technology spread in 25000 ha of sorghum in western coastal districts of Andhra Pradesh.
  • Identified two strains (kusmi and rangeeni) on the basisi of amino acids content in lac insect. Found the toxicity of Cypermethrin (0.001 %), Decamethrin (0.003 %), Fenvalerate (0.005 %) and Dicholorvos (0.01, 0.02, 0.04 and 0.08 %) were toxic to lac insects.
  • 21 F3 progenies generated and found promising for shoot bug in rabi varietal development.
  • Developed the IPM Technology for shoot fly for rabi season in dryland situation.

Recent awards and recognitions:

  • Rythu Bandhu Award : Received from Nest Foundation, 3-6-747/2, Street No.12, Near Oxford Grammar School, Himayathnagar, Hyderabad – 500029, Rythu Mitra Groups, in 2014 during 2014
  • Received the “OUTSTANDING SCIENTIST AWARD” for development and dissemination of sorghum cost effective production technologies from Dept. of Agriculture, Andhra Pradesh State Government and Farmers Welfare Societies and Rythu Mitra Groups of Guntur district in 2012.
  • The Best Entomologist Award : Received from the Nightingale Social Welfare Society, about outstanding contributions on overall development and dissemination of cost-effective integrated pest management technologies for shoot fly in sorghum on 30th May, 2013.
  • Andhra Pradesh State, Hon’ble Minister for Agriculture and Agriculture Technology Mission, Sri. Kanna Lakshmi Narayana Garu given the appreciation letter on 24th February, 2014 for the commendable work on promotion of sorghum crop cost- effective technologies (zero-tillage, dual purpose sorghum and protection, etc) in rice-fallows of Coastal A.P
  • The “Best Popularization Effort” to promote sorghum cultivation in rice-fallows under zero-tillage in Andhra Pradesh during 2009-10 by Directorate of Sorghum Research, Hyderabad.

Current collaborative activities:

  • Transfer of technologies to different end users (Agricultural Universities, State & Central government Organizations and NGOs etc)
  • Training giving to seed producers, farmers, agricultural officers, etc on cost effective plant protection technologies for sorghum cultivation and its related technologies in collaboration with state dept of Agriculture.
  • Promotion of cost - effective IPM technologies for sorghum cultivation in rice - fallows under non traditional areas under private-public partnership.
