Entity of the month
Insects destroy a very large fraction (thought to be up to 40%) of the global agricultural output and necessitate use of millions of tons of toxic insecticides and insect repellents that are environmentally unfriendly and can be harmful to other species including humans. Finding safe and effective repellents is, therefore, a top priority for agrochemical companies.
