<p>Red nets are better at keeping away a common agricultural insect pest than typical black or white nets, according to a new study. Researchers experimented with the effect of red, white, black and combination-colored nets on deterring onion thrips from eating Kujo leeks, also called Welsh onions. In both lab and field tests, red nets were significantly better at deterring the insect than other colors. Also, in field tests, onion crops which were either partially or fully covered by red netting required 25-50% less insecticide than was needed for a totally uncovered field. Changing agricultural nets from black or white to red could help reduce pesticide use and the related negative impact it can have on the environment, while supporting more sustainable and effective agricultural practices. </p>
