A pesticide may refer to a particular compound or chemical substance. It can be a fungicide, herbicide, insecticide, mulluscicide, nematicide, rodenticide, and others that are used to target certain unwanted living organism.
Since the 1900s, people have been using different types of pesticides and the environment is filled with various levels of these chemicals. These include organochlorine, organophosphate, carbamates, and pyrethroids, which all became successful in controlling pests. However, consumers have to be aware of the positive and negative impact of these chemicals on the environment.
There are positive effects of using pesticides and the environment actually benefits from the direct or indirect results of pesticide application.
One major benefit of pesticide use is the eradication of certain species that pose threats to forest trees. For example, budworms or loopers can kill thousands of trees due to defoliation. To address this, scientists have studied the Bacillus thuringiensis var. Kurstaki or Btk, a bacterium that naturally occurs in the environment. It can kill insects, hemlock looper, larvae, and budworms.
