In December 2016, the Ministry of Agriculture, Cooperation and Farmers Welfare, Government of India (GoI) in a notification endorsed the implementation of ‘refuge-in-bag’ (RIB) for Bt cotton and specified Bt trait purity standards and proportion of non-Bt refuge seeds in the blend. A subsequent notification directed the Bt seed companies to implement RIB with isogenic refuge, wherever available, and implement a complete shift to isogenic refuge by December 2019. This is a welcome move with the clear intentions of phased replacement of structured refuge, which was never adopted by the cotton farmers, with RIB.Full Text

The refuge deployment for Bt-cotton will undergo a sea change from the planting season of 2020. Stepping back, the Genetic Engineering Appraisal Committee (GEAC), Ministry of environment, Forest and Climate Change, Government of India (GoI) had approved the first transgenic single-gene Bt-cotton hybrids in India in 2002 and the next-generation cotton transgenics with stacked Bt genes (Bollgard II®) in 2006, and had recommended sowing of 20% area with non-Bt cotton as ‘structured’ refuge for both types of Bt-cotton. Over time, refuge planting became voluntary and cotton farmers ignored planting of refuge to maximize their returns from a field of 100% Bt-cotton.Full Text

In an article on ‘hybrid Bt-cotton’, Gutierrez1 concludes that government agencies should encourage development of high-density short-season (HDSS) varieties as a straightforward solution to stabilize cotton production in India which, in his view, has suffered due to the many ills of cultivating Bt-cotton hybrids since 2002. While HDSS varieties of Gossypium hirsutum could provide another option to the Indian cotton farmer under subsistence farming conditions, technology stakeholders need to be watchful and factor in the hard lessons learnt from the pre- and post-Bt cotton eras.Full Text

Growing a refuge crop is an integral part of transgenic crops with gene(s) from Bacillus thuringiensis (Bt) and a key requirement to delay evolution of Bt resistance in target pests. Poor refuge planting with Bt-cotton in India, for many years, is a major reason for the outbreak of Bt resistance in pink bollworm and consequent erosion in the efficacy of Bt-cotton technology. As a remedial measure, the Ministry of Agriculture, Government of India has directed complete shift to the marketing of Bt-cotton seeds blended with non-Bt refuge cotton seeds (refuge-in-bag; RIB) from this (2020) season onwards. The strengths, weaknesses, opportunities and threats of RIB Bt-cotton combination in the context of known behaviour of cotton lepidopteran pests and prior exposure to the same Bt toxins since 2002, is discussed. Bt-cotton with RIB, if implemented with strong stewardship, will have far-reaching benefits and is expected to delay Bt resistance development in target lepidopteran cotton pests. However, the relevance of RIB for Bt-resistant pink bollworm could be in question.Keywords
