What are the advantages and disadvantages of chemical controls?

Advantages and Disadvantages of Chemical Pest Control

• Efficiency. Pesticides offer a fast-acting and often highly effective means to kill or control a specific type of pest.
• Evolution. Overuse of chemical pest control promotes the evolution of pesticide resistance.
• Toxicity and Non-Target Effects.

What are some negative effects of using pesticides to control insects?

Pesticide exposure can be linked to cancer, endocrine disruption, reproductive effects, neurotoxicity, kidney and liver damage, birth defects, and developmental changes in a wide range of species. Exposure to pesticides can also alter an organism’s behavior, impacting its ability to survive.

What are the disadvantages of insecticide?

Disadvantages of insecticides Non-target organisms – Insecticides can kill more than intended organisms and are risky to humans. Resistance – Insects when repeatedly exposed to insecticides build up resistance until finally, they have little or no effect at all.

What is the disadvantage of chemical control?

Controlling pests becomes more efficient when chemical method is used. Another disadvantage of chemical pest control is non-target effects and toxicity. Many chemicals kill even the beneficial insects such as bees and natural predators. If misused or mishandled, chemicals can intoxicate and even kill humans.

What are the disadvantages of physical pest control?

Some disadvantages of integrated pest management, or IPM, are that its use requires regular monitoring, it cannot be used for all pests, it can be hard to determine when to use sprays, it doesn’t work with all environments and practitioners have to understand how IPM works and follow practices consistently.

What are the disadvantages of using chemicals in agriculture?

Disadvantage: Unsustainable Soil Conditions Nitrogen is often regarded as a highly effective and cheap fertilizer. However, repeated use of the chemical can cause an imbalance in the pH of the soil, eventually rendering it useless for growth of any kind.

What are the advantages of chemical pest control?

Using chemicals can help a farmer eliminate the entire pest population almost instantaneously by simply administering the chemical in the environment occupied by the pest. A major advantage of chemical pest control is its efficiency.

What are the pros and cons of pesticides?

In other words, pesticide safety is not taken lightly. It is easy to knock the use of chemicals, until you really examine the pesticide and herbicide pros, now and in the past. They prevent spread of disease. It is estimated that since 1945, the use of pesticides has prevented about seven million deaths from insect spread diseases.

What are the different types of pest control?

Chemical pesticides include three different classes of chemicals: herbicides, insecticides and fungicides. Each controls a specific type of pest and each has its own advantages and disadvantages.

How many pests are resistant to chemical pest control?

In other words, chemical pest control acts as a type of artificial selection for pesticide resistance. According to “Essential Environment,” by 2000 there were over 2,700 known cases of resistance by 540 species of pests to over 300 pesticides, including the diamondback moth and the green peach aphid, both of which are agricultural pests.
