On the other hand, the disadvantages of widespread use of pesticides are significant. They include pollution and death of domestic animals, loss of natural pest antagonists, resistance to pesticides, decrease in honey bees and pollination, losses to adjacent crops, losses of fisheries and birds, and pollution of groundwater. Excessive use of chemical pest control promotes the evolution of pesticide resistance. When pesticides are applied, people who are more resistant are more likely to survive.
If their resistance to the chemical has a genetic basis, they will in turn pass these genes to their progeny so that the population becomes more resistant over time. In other words, chemical pest control acts as a type of artificial selection for pesticide resistance. According to Essential Environment, in 2000 there were more than 2,700 known cases of resistance of 540 pest species to more than 300 pesticides, including the diamond-backed moth and the green peach aphid, which are agricultural pests. There are disadvantages to pest management.
While it may seem like a good idea to destroy all pests as soon as you see them, some people should realize that a pest does not equal an infestation. Therefore, if only one pest is seen, it may not make sense to spray. In addition, pest spraying is extremely expensive. Some pests are resistant to common insecticides and require multiple sprays and constant monitoring of the area to keep them at bay.
Some companies use toxic chemicals to kill pests that are harmful to both living things and the environment. Pest spraying is also an inconvenience, with many hours of lost productivity as a result of having to move to a different floor or building while spraying the area. Another disadvantage of chemical pest control is non-target effects and toxicity. Many chemicals kill even beneficial insects such as bees and natural predators.
If misused or mishandled, chemicals can poison and even kill humans. Pesticides that cause hypercalcemia are chemicals such as calciferols, cholecalciferol, and ergocalciferol. On the other hand, chemicals are disadvantageous as a means of controlling pests because they promote the evolution of pests. However, despite the clear disadvantages of pest control, there are also many clear advantages to using them.
Companies that offer this type of pest control are usually well aware of the habits of local pests and have an arsenal of techniques to completely eliminate them and prohibit their return. This is because a farmer only needs to identify the pest and then look for a chemical that kills that particular pest without harming the beneficial insects. If you choose ecological pest control, you run the risk of guaranteeing a little longer time to see the results. The right combination of control measures can often suppress pests already present and prevent them from accumulating again to a level where they are causing unacceptable damage.
The use of this chemical pesticide is very important for potato crops due to soil-borne nematodes. University of the West Indies (UWI) * Provide undergraduate training in agriculture and related fields* Conduct agricultural research to improve cultivation methods and control pests and diseases. Pests and their predators are temporarily eradicated and when pests begin to increase in number, there are not enough predators to treat them, which means that pests are allowed to increase severely in number, which has an undeniably worse effect on the environment than if pesticides were not used and consequently, kill the predators of the plague. Pesticides present in the environment lead to their entry into the biosystem, which accumulates in organisms.
The use of many different tactics to control a pest problem tends to cause the least disruption to living organisms and non-living environments at the treatment site. Because of these potential health risks, the cost of developing new pesticides has increased dramatically in recent years. The government has engaged and slowed the progress and development of pesticides and the rising costs of new products. Relying on pesticides alone for pest control can cause pests to develop resistance to pesticides, cause outbreaks of other pests, and damage surfaces or non-target organisms.
Chemical pesticides based on emulsifiable concentrates have no residual effect on fruits and vegetables. . .
