Insects Don't Develop Resistance

Despite the many advantages that chemical pesticides provide in controlling plant pests, most have serious limitations as well. Not only do they have to be applied carefully because of possible hazards to humans and animals, but insects often develop resistance to them very quickly And yet there is an insecticide available that has neither of these drawbacks. It is safe and effective, and it has been in use for years without any sign of insect resistance developing. And new means are being devised for improving it and making it more effective.

The insecticide is natural pyrethrum, extracted from a daisy grown mainly in Kenya, it has been in use in the West since the early twentieth century. At one time pyrethrum powder was mixed with kerosene to create a spray liquid insecticide. Today pyrethrum flowers are processed into extracts to serve domestic, industrial and agricultural needs. Insecticides using natural pyrethrum as active ingredient include Fairfield American's Pyrenone.
