Scientists Create Pesticide Sunscreen

Chinese agricultural scientists say they've developed a sunscreen for pesticides that allows the chemicals to remain effective for longer periods of time.

The scientists say the sunscreen will become increasingly important as global warming continues.

A team of scientists, led by Li-Xiong Wen of the Beijing University of Chemical Technology, says the technology shields pesticides from ultraviolet light. The research shows the pesticides, when protected by the sunscreen, can be exposed to sunlight for at least twice as long without degrading.

Wen and colleagues believe such pesticides will be more effective, reducing the amount required and costs to farmers. It could also mean cleaner water, as the risks of excess pesticide contamination will be lowered.

The research appears in the current issue of the journal Pest Management Science.
