Pesticides Uses

Insect have more species (over one million already described) than any other form of animal life and are in many ways the most indestructible form. About 1 percent of the species offer hazard to human and animals. Human and pests fight a continuous battle for food and shelter. Insects alone claim about 10 % of our crops in US, and about 14 percent in worldwide, various misery causing diseases are carried by insect malaria, yellow fever, typhus, and plague to name a few. For us to survive at current population levels, pesticides must be used and new ones constantly developed. When insecticide applied widely, all but a few of the local insects are destroyed, but the remaining ones are those most resistant to the destroying agent. After destroying generation, this selection makes the surviving insects increasingly resistant to the destroying agent. Eventually, complete resistance may occur. This phenomenon is seen with medical product, and all types of pesticides. In an effort to retard the rate at which such resistance develops, the concept of integrated pest management has been developed, which will be more fully discussed later.

The annual loss attributed to agricultural pest nears 10 percent of the total agricultural production value per year, perhaps $15 billion in the united states alone. Without chemical control and accompanying means such as IPM, the losses would be impossibly large and the quality of products unacceptably low. Every citizen must be concerned with this tremendous loss and take part in the warfare against normal and constant enemies. Without pesticide use, we starve. Use of pesticides is a most important step in the conservation of our resources and in increasing the productivity of our soil. The low cost manufacture of increasingly complex chemical agent offers an exception challenge to processing specialists.

Chemistry pervades every of agribusiness. The use of chemicals was limited to about 50 compounds in 1940, now several hundred are used in perhaps 50,000 commercial formulations. Effectiveness and economical production are important, but safety to farmers, consumers, and the general public is so important that federal laws strictly demand it.
