KLEA is a drone service designed to provide farmers with a non-chemical approach to pest control. The project provides the user with multispectral analysis that can be used for early detection of insect infestations. Based on this analysis, farmers can define a targeted application of biological pest control, based on the release of natural predators, thus avoiding the need for chemical pesticides. KLEA combines two services that are, until now, separated: the analysis of a field and an immediate response to the results through the release of beneficial insects. It could help small farming businesses to cultivate without the use of pesticides: by using the service, farmers can enjoy the benefits of high tech, precision farming without the need for expensive large-scale equipment.
