The use of toxic pesticides to manage pest problems has become a common practice around the world. Pesticides are used almost everywhere — not only in agricultural fields, but also in homes, parks, schools, buildings, forests, and roads. It is difficult to find somewhere where pesticides aren’t used — from the can of bug spray under the kitchen sink to the airplane crop dusting acres of farmland, our world is filled with pesticides.
Pests live where they are not wanted or cause harm to crops, people, or animals. Pesticides can help get rid of them. Pesticides are not just insect killers. They also include chemicals to control weeds, rodents, mildew, germs, and more. Many household products contain pesticides.
Pesticides can protect your health by killing germs, animals, or plants that could hurt you. However, they can also be harmful to people or pets.
From the ridge overlooking fields his family has tilled for 120 years, Ken Tschumper surveys the lush crops of alfalfa and corn he raised this summer without pesticides or chemical fertilizers.When he stopped using chemicals six years ago on his 230-acre dairy farm, neighbors ridiculed Mr. Tschumper’s inexpensive system of spreading manure and rotating crops to nourish his soil and repel insects, weeds and diseases.
Integrating predatory insects into a farm, such as ladybugs or predatory mites, can help kill off pests. Jules Pretty found that farms that provide habitats for pest predators have averaged a 79 percent increase in crop yields over previous agricultural systems that did not use pests to fight pests.Organic pesticides are not only healthier for people and the environment but they allow farmers and producers to make the most out of their resources by turning agricultural outputs into natural pesticides.
The science — and the people — had spoken: Methyl iodide as a proposed replacement for the fumigant methyl bromide, an ozone depleter being phased out by an international treaty, was not really a worthy alternative at all. But the road to toxic-free farming is a long one and this battle was only the beginning.
Organic farming is an alternative agricultural system which originated early in the 20th century in reaction to rapidly changing farming practices. Organic agriculture continues to be developed by various organic agriculture organizations today. It relies on fertilizers of organic origin such as compost, manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting. Biological pest control, mixed cropping and the fostering of insect predators are encouraged.
