About
WeedOUT is an Israeli ag-tech startup that has developed a novel biological herbicide to combat herbicide-resistant weeds. The company's solution utilizes proprietary weed pollen derived from male plants, which fertilizes female weed ovules, resulting in nonviable seeds and effectively inhibiting the growth of a new generation of resistant weeds. This green solution offers an alternative to traditional chemical herbicides, which have become less effective due to weed resistance. WeedOUT's technology is designed to be species-specific, with its first product targeting the Palmer amaranth weed, a major threat to crops in the US, Brazil, and Argentina. The company's approach is inspired by sterility techniques used in controlling unwanted insects and aims to provide a sustainable, long-term solution for weed management.
