Cotton Pesticides Impacting Bee Population
Like many other plants, the cotton plant too has been benefitting from bees. While bees feed on the cotton plant, they play a leading role in pollination. This mutually beneficial relationship is proving to be fatal to the bees ever since insecticide sprays have been resorted to. Cotton spraying is the major cause of bee deaths – more than from spraying of other crops.
Why are bees being killed without any concern for their role in pollination? The main reason is non-adherence to specific label directions concerning bees. Insecticides that are toxic to bees have label directions for use to minimize harm to them. The continuous decline in the population of one of the finest natural pollinators is a cause of concern for the environmentalists. And, all this can be avoided if cotton farmers adhere to the label directions in letter and spirit. It will help to educate the cotton growers that in the long-term, they will be the ones who will suffer from the dwindling bee population. What most people have come to recognize is the huge impact that bees have on our food supply. Beekeepers are doing a great service by domesticating bees and contributing to pollination in a great way.
