It is interesting that some pesticide active ingredients are also used as medicines to control human pathogens. The first step in using a pesticide correctly is to identify the pest. Because pesticide products can be very specific in their pest-control spectrum, it is vital to identify the pest correctly. Further, an incorrect identification of the pest followed by a prescription pesticide application could harm beneficial plants or animals, pollute the soil, water or air, and promote the buildup of other pests previously controlled by their natural enemies. After the pest has been positively identified, an evaluation should be made to determine whether the pest population is at an injurious level to the crop, animal or substance that is to be protected.
Pestcontrol measures can sometimes cost more than pest damage.
The next step is to determine the most appropriate methods of pest control. For example, a fly swatter is an excellent nonpesticidal tool to control a few houseflies or crickets that might be invading a homestead. After the decision has been made to use a pesticide, based upon the correct identification of a pest at an injurious level, selection of an appropriate product is the next step in using pesticides correctly. Recommendations for appropriate pesticides to control specific pests are available from your county Extension office. The following step in using a pesticide correctly is the most important.
