Highlights of Brain Storming Session On “Insecticide Resistance Management in Horticultural Crops – Way Forward!”
Brain storming session on “Insecticide Resistance Management in Horticultural Crops – Way Forward!” was organized jointly by the Association for Advancement of Pest Management in Horticultural Ecosystems (AAPMHE) and the Indian Institute of Horticultural Research (IIHR) on 30th Aug, 2014 at IIHR, Hessaraghatta, Bengaluru. 65 participants comprising researchers from different ICAR institutes and State Agricultural Universities, representatives from private sector and students participated in the deliberations.
Dr. K. R. Kranthi, Director, CICR, Nagpur delivered the key note address on the overview of insecticide resistance in arthropods with special reference to cotton bollworms and Bt cotton. He spoke on the rationality behind the succession of transgenic cotton hybrids like Bollgard, I, II, etc. He expressed concern that in spite of several research efforts on IRM, the ground reality remains grim with commercial interests of pesticide firms and dealers determining the use or ban of insecticides. Dr. B. V. Patil, Ex-Vice-Chancellor, UAS, Raichur emphasized the role of young researchers in educating farmers. He mentioned that next to paddy, vegetables such as chili, brinjal and tomato receive more pesticides. Lack of knowledge on new molecules, mode of action, misuse/overuse of insecticides are the causes for emergence of resistance in arthropods especially in bollworms and sucking pests. He stated that new molecules with increased efficacy are available for managing resistance; there is a need to educate farmers to solve the resistance problem. Dr. T. Manjunatha Rao, Director, IIHR, in his presidential remarks mentioned that crop production and productivity is important for farmers. He stated lack of knowledge on appropriate usage of insecticide in a long way has led to the development of resistance. He requested the scientists to come out with knowledgeable publications that could reach policy makers and farmers for the betterment of the country.
Brain storming was conducted in four sessions, viz., Chemical interventions for IRM, Bt crops/Molecular genetics, Insecticide Resistance Management & Integrated Pest Management and IRM – New molecules: Industrial and Farmers perspectives comprising of 14 presentations by various speakers viz., Dr. Irani Mukerjee, IARI, New Delhi, Dr. T. Venkatesan, NBAII, Bengaluru, M. Mani, NBAII, Bengaluru, Dr. Debi Sharma, IIHR, Bengaluru, Dr. N. Srinivasa, GKVK, Bengaluru, Dr. K. S. Mohan, Monsanto, Bengaluru, Dr. G.M.V. Prasada Rao, ANGRAU, Guntur, Mrs. D. Lokeshwari, IIHR, Bengaluru and Mrs. Gandhi Gracy, NBAII, Bengaluru, Dr. B.V. Patil, UAS, Raichur, Karnataka, Dr. M. Mohan, NBAII, Bengaluru, Dr. S. Sriram, IIHR, Bengaluru, Dr. V. Sridhar, IIHR and Dr. M. R. Hegde, IIHR, Bengaluru. In the plenary session following recommendations were prescribed.
- Use of non-chemical strategies - pest exclusion, host-free periods, crop rotation, biological control, use of Bt, synergists and micronutrients was emphasized.
- The waiting period for pesticides on crops has to be furnished along with the label claim for residue free produce and for effective IRM.
- Compatibility studies involving insecticides, fungicides, fertilizers, weedicides etc. are urgently required.
- Improper disposal of left over pesticides into wetlands, water bodies should be strictly punished under the law.
- Clear guidelines may be provided for recommendations for crops where there is no label claim (Action: CIB, DPP, ICAR, Plant Protection Section).
- Studies on ready to use mixtures/cock-tail formulations have to be initiated as the composition of such cock tails is often unknown.
- The laws governing the manufacture, trade, movement/transportation and use should be strictly monitored by health authorities and the state government should take the initiative.
- Information on setting up and maintaining an IPM monitoring program has to be made available for the farming community through farm advisors to determine the best application timing for pesticides to minimizing pesticide use.
- A toll-free customer service telephone line has to be made available for farmers by state government to report unexpected levels of damage from the pests and control failures to monitor and combat resistance.
- Awareness on new molecules, formulations and applicators should be created among extension personal and then at the farming community level.
