英文原文阅读

Farmers all over the world are suffering from a "pesticides treadmill". Pests are growing resistant to their sprays. So farmers have to spray ever more to have any effect, or buy new, more expensive chemicals. But at the same time world cotton prices have stagnated. So farmers face a serious squeeze on their profits, combined with growing threats to their health from the pesticides. Is there another way?

Maharashtra state is a centre of India''s cotton growing -- much of it on small farms such as those in Wardha district. Here many insects live in the cotton fields. The most destructive, the American bollworm, is spreading and growing resistant to pyrethroids and other cheap pesticides. To save their crops, farmers are spraying typically 10-12 times in a single growing season. One farmer, Vittal Rao Karamore, says he sprayed his fields 14 times.

Partly as a result, cotton farmers have become the biggest users of pesticides inIndia. Cotton occupies just 5% of the country''s fields, says NRI entomologist Derek Russell, but those fields use more than half of the country''s pesticides.

This repeated spraying is very expensive, forcing many farmers into debt. And it is counter-productive, encouraging resistance to the chemicals among the pests. So the next year the farmer must spray even more. Spraying often pollutes drinking water and neighbouring crops, and is a health hazard for farmers and their families. It is also hard labour. To spray a hectare of cotton, the farmer carries equipment weighing about 40 kilograms for 10 kilometres up and down the rows in the hot sun. No wonder women such as Bindutai Bhoge, a widow from thevillageofKaranji Bhoge, employ men to do their spraying.

So heavy spraying increases the vulnerability of farming communities to debt and poor health, while reducing the money the farmers have for other vital needs, such as educating their children. Farmers like Sulochana Balpande from Karanji Kaji village, who grows cotton partly to provide money to educate her two daughters.
