BT cotton is a widely planted and controversial crop of India. It produces its insecticides. In the year 2002, these seeds were introduced in India and are hugely grown in the Indian market up to 90%. Many of its supporters have stressed that the increase in its yields has reduced pesticide usage, which is untrue found in the study on the impact of BT cotton in India.
An analysis co-authored by anthropologist of Washington University published in the Journal called Nature Plants says this cotton has tripled the production since the year of its introduction.
Glenn Davis Stone, a professor of sociocultural anthropology, mentioned that India has experienced much larger production gains before the introduction of BT cotton and so it is time to rethink the strategies of fertilization and other pest population dynamics. There are mixed reactions about the BT cotton among the users. This study is carried out for a time duration of 20 years. India has two devastating caterpillars’ pests: among which BT cotton is one that is American Bollworm, and the second one is the pink bollworm, but it is worse than the previous. He further added,” BT plants were highly vulnerable to other insect pests that proliferated as more and more farmers adopted the crop. Farmers are now spending much more on insecticides than before they had ever heard of BT cotton. And the situation is worsening.”
His partner in the research is K.R.Kranthi, the former director of India’s Institute of Cotton Research. He is presently serving as a Head of technical division at the Washington International Cotton Advisory Committee. He further briefed about the situation in India about how farmers are spending more on seeds, fertilizer, and insecticides. However, he concluded that the impact of this cotton on agriculture will lead to expensive farming.
