Organic farming to mitigate biotic stresses under climate change scenario

Background Climate change is inevitable owing from modern-day chemical agriculture, exerting detrimental impacts on sustainable crop production. Global agriculture is now facing serious threats from biotic stresses like weeds, pests, diseases, etc. These stresses not only hamper growth and production but also reduce crop quality. Main body of the abstract Exclusive reliance on synthetic inputs to tackle biotic stresses has created resistance, resurgence, residues, etc., leading to environmental pollution. Although plants adopt defensive mechansims, such biotic stresses need to be addressed properly with various eco-friendly organic farming approaches. Suitable modification and adoption of various organic agronomic practices (manual, mechanical, cultural, and biological) such as soil solarization, crop rotation, intercropping, tillage, sowing time and method, nutrient, water and intercultural operations, organic formulations, selection of resistant/tolerant varieties, etc., can mitigate the negative impacts of biotic stresses to a high extent resulting in uplift in crop production as well as the quality of produce. Microorganisms not only alter soil health positively for high crop production but also alleviate biotic stresses through bio-stimulant properties. Various indigenous technical knowledge approaches show great promise to tackle biotic stresses further. Short conclusion Adequate research, integration of multiple technologies, build-up of awareness, etc., are the keys for successful organic plant protection under changing climate scenario.
