The chemicals are produced in different plant parts depending on the plant species, like the seeds of the neem tree and the flowers of chrysanthemums. Although natural botanical extracts can be very effective insecticides, they are not typically used in large-scale managed ecosystems, as the extraction process is often costly continued see video........
