Pest Control Services And Technology
Conservation strategies such as mixed plantings and the provision of flowering borders can be more difficult to accommodate in large-scale crop production. There may also be some conflict with pest control for the large producer, because of the difficulty of targeting the pest species, also refuges may be utilised by the pest insects as well as by natural enemies. Some plants that are attractive to natural enemies may also be hosts for certain plant diseases, especially plant viruses that could be vectored by insect pests to the crop.
4. Establish action threshold (economic, health or aesthetic) - How many are too many? In some cases, there is a standardized number of pests that can be tolerated. Soybeans are quite tolerant of defoliation, so if there are a few caterpillars in the field and their population is not increasing dramatically, there is not necessarily any action necessary. Conversely, there is a point at which action <i>must</i> be taken to control cost. For the farmer, that point is the one at which the cost of damage by the pest is <i>more</i> than the cost of control. This is an economic threshold. Tolerance of pests varies also by whether or not they are a health hazard (low tolerance) or merely a cosmetic damage (high tolerance in a non-commercial situation).
Many of the chemicals that are used in the pest control industry are restricted by various laws. The industry has seen many shady business operations over the years where a supposed pest control technician would come in and spray your house with kerosene for $100 dollars and claim they had solved your problem.
In the past entomologists working on pest insects attempted to <i>eradicate</i> species. This has rarely worked except in islands or controlled environments and raises ethical issues. Over time the language has changed to terms like <i>control</i> and <i>management</i>. The indiscriminate use of toxic and persistent chemicals and the resurgence of pests in the history of cotton growing in the US has been particularly well studied.For More Information please click here pest control chula vista ca
