Farmers and gardeners don't have to worry about poisoning themselves, their families, or their pets when they treat their crops or plants. There are no toxic chemicals to store or worry about children or animals discovering stored pesticides. Compared to chemical pest control, the advantages of biological control are numerous. Biological control is a natural mechanism that does not employ pesticides and therefore leaves no xenobiotic residues after treatment (Chapters 21 and 23212).
The first attempts at biological control using soil microbes followed Waksman's discovery of antibiotic-producing microbes in soil. Unfortunately, most, if not all, of those attempts failed outright. While chemical controls are usually effective, they are usually seasonal and need to be reapplied in each growing season. Biological controls may take longer to deliver the desired results, but the benefits can last well beyond your initial investment.
Many chemical pesticides persist in the environment and pest populations can increase their resistance to chemicals over time. However, many invasive pests were imported and lack natural predators in their new environment, making biological control difficult in some cases. Chemical pesticides are often used to control diseases, pests, or weeds. Chemical control is based on substances that are toxic (poisonous) to the pests involved.
When chemical pesticides are applied to protect plants from pests, diseases, or weed overgrowth, we talk about plant protection products. Of course, it is important that the plant in need of protection does not suffer from the toxic effects of protective products on its own. When pests need to be controlled over large areas of land, pesticides prove to be very cost-effective, even when less human labor is needed to maintain the pesticide process. Rodenticides are chemical pesticides, designed specifically for the extermination of rodents such as rats and mice.
To be more elaborate, some positive alternative methods have already been developed, such as physical barriers, cultivation practices, genetic improvements, semiochemical use and biological control options with beneficial insects and mycopesticides (Hubert de Bon et al. A number of beneficial microorganisms can also be used to improve plant health and control pests and diseases. Chemical pesticides, often based on artificial substances, are designed to reduce the vitality of pest populations and leave plants unharmed. After World War II, the use of real chemical pesticides began, and today there are hundreds of chemical pesticides available for use in agriculture and horticulture.
The use of this chemical pesticide is very important for potato crops due to soil-borne nematodes. Controlling pests with their natural enemies, including parasites, predators, diseases and competing organisms, is called biological control. Scientific advances have created many new chemical pesticides that mimic and, in some cases, improve the effectiveness of natural substances. The modern era of pesticides began with the discovery of chemicals such as dichlorodiphenyltrichloroethylene and organophosphorus (OP) insecticides that were highly effective against insects.
In terms of biotechnology, humans use biological control agents for the protection of the resources they want. These controls are often administered as emergency measures to suppress blooms that threaten aquaculture facilities or other spatially restricted regions, and their use can significantly accelerate the disappearance of a bloom or eliminate toxins from the water. Improvement of the factor (s) that limit the growth or survival of control agents is necessary for biological control to work. .
