This was published in Eng Life Sci. 2020;20:525-534 Scientists have uncovered why a food-ingredient-based pesticide made from safflower and cottonseed oils is effective against two-spotted spider mites that attack over a thousand species of plants while sparing the mites' natural predators. An international team of scientists has uncovered how a bio-pesticide works against spider mites while sparing their natural predators. The findings, published in the journal Engineering in Life Sciences on October 7, 2020, could present farmers and gardeners with an eco-friendly alternative to synthetic pesticides.
