The benefits of using pesticides are larger harvests for farmers. This makes farming more efficient, and fewer acres need to be cultivated. food and fiber are subject to damage by pests in every stage of production, transportation and storage. Weeds cause extensive crop losses (see http://www.smallgrains.org/springwh/June03/survey/survey.htm).
During the last 50 years or so, chemical synthesis of pesticides has increased considerably. Now, there are more than 55 classes and 1,500 individual substances produced for pesticide use. Pesticides can be classified as insecticides, fungicides, herbicides, rodenticides, bactericides, algacides, etc. depending on the pests they target.
The risk of using a pesticide depends on what type it is. Pest controls fall into three major categories: chemical, physical, and biological. Chemical is by far the most widely used, primarily because of its affordability. Chemical controls can be classified into three groups: inorganic, synthetic organic, and natural organic.
Note the different uses of the words "organic" here, which can be confusing. Organic farming is a component of sustainable living, and generally uses no pesticides at all. However when it does, these are "natural" such as neem oil. "Organic" is also a chemistry term, which is the way it is meant with the term "synthetic organic." ...
Pest control for destructive beetles of vegetable crops
You are a farmer growing vegetable crops that depend on a very delicate species of bee for pollination. Your crops have been invaded by a destructive beetle that reproduces rapidly. In past years this type of beetle has destroyed up to 60 percent of your harvest. Which form of pest control would you choose to save your crops? Detail why you would choose this method. Is there any method you would not use? Explain your answer.View Full Posting Details
