Why do farmers who use chemical pesticides to control pests have to increase the amount applied to their fields each year?
Farmers may need to increase the amount of chemical pesticides due to the development of resistance in pest populations. Over time, pests can adapt to the chemicals used, becoming less susceptible and requiring higher doses for effective control. Additionally, prolonged pesticide use can disturb ecological balance, leading to more severe pest outbreaks that require increased doses to manage.

What is chemical control?
Chemical control is the use of chemical substances (such as pesticides or herbicides) to manage and control pests, diseases, or weeds in agricultural or urban settings. It is a common method of pest management but can have negative environmental impacts if not used properly.

One common chemical used for pest control is pesticides, which are substances that kill or control pests like insects, rodents, or weeds. Pesticides can be synthetic (man-made) or natural (derived from plants or microorganisms) and are regulated to ensure they are used safely and effectively in controlling pests.

What reason might a farmer have for using biological control instead of chemical pesticides?
A farmer might choose biological control over chemical pesticides to minimize negative impacts on the environment and human health, reduce chemical residues on produce, and promote sustainable agricultural practices. Biological control methods also have the potential for long-term pest management and are often more target-specific.
Type of farming that doesn't use pesticides?
* Organic agriculture actually organic farming does use pesticides, what you're looking for is "biological control" which means it allows the use of synthetic fertilizers but trades chemical pest control with biological pest control. in biological control one applies parasitic wasps, entomophagic fungie and other such agents in much the same way one would apply chemical pesticides.
What is chemical control?
Chemical control is the use of chemical substances (such as pesticides or herbicides) to manage and control pests, diseases, or weeds in agricultural or urban settings. It is a common method of pest management but can have negative environmental impacts if not used properly.
What are some biological alternatives to chemical pesticides?
Some biological alternatives to chemical pesticides include introducing natural predators or parasites to control pest populations, using insecticidal soaps or oils derived from plants, and planting trap crops to attract pests away from main crops. Crop rotation and intercropping with pest-repellent plants can also help reduce the need for chemical pesticides.
What is a chemical used to prevent destroy or repel pests?

What is the definition of pesticides?
A pesticide is a chemical substance sprayed on crops to kill insects, pests and bacteria. The chemical agents called pesticides include herbicides (for weed control), insecticides, and fungicides. More than half the pesticides used in the United States are herbicides that control weeds. The United States Department of Agriculture (USDA) estimates indicate that 86 percent of U.S. agricultural land areas are treated with herbicides, 18 percent with insecticides, and 3 percent with fungicides. The amount of pesticide used on different crops also varies. For example, in the United States, about 67 percent of the insecticides used in agriculture are applied to two crops, cotton and corn; about 70 percent of the herbicides are applied to corn and soybeans, and most of the fungicides are applied to fruit and vegetable crops.They kill "pests".
Should chemical pesticides be banned?
Chemical pesticides harm the ecosystem, the environment, and could be harmful to humans; however, without them, we would not be able to produce enough food for the current population. The best alternative is to put more energy into finding natural pesticides (such as garlic oil) which don't harm the environment, but keep insects from ruining the crops, and to make those natural pesticides available before banning chemical pesticides.
Why do agricultural use pesticides?
Agricultural pesticides are used to control pests such as insects, weeds, and diseases that can damage crops and reduce yields. Pesticides help farmers protect their crops and ensure a higher quality and quantity of produce. Proper use of pesticides can help increase agricultural productivity and ensure food security.
What are the advantage in using chemical pesticides?
The chemicals that kill the pests sometimes have side-effects. They may do harm to creatures that you do not want to kill . Legal pesticides are tested to minimize the danger, but mistakes can be made . You get better tasting veggies and fruit!
What are four ways that chemists control the rates of chemical reactions?
Increase in Surface area,Increase in temperature,Increase in concentration,and the presence of catalysts or inhibitors.
