Inappropriate pesticide use, including the overuse of pesticides, is still widespread. The overuse of pesticides can lead to higher production costs for the farmer and may adversely impact both food safety and the environment. It is, therefore, important that farmers and agricultural service providers practice rational pesticide use.

In addition, the app helps users to calculate the total amount of pesticide required so that they do not have pesticide leftover, which would cost the farmer money unnecessarily, as well as pose challenges with pesticide disposal
