How do pesticides increase food production?

How do pesticides increase food production?

Because the animals tend to eat lots of organisms from the level below in food chains, the concentration of pesticide in the bodies of organisms increases at higher levels of food chains. This build-up of toxic substances in living organisms is known as bioaccumulation.

How do pesticides help in increasing the produce?

With the introduction of pesticides, farmers have been able to produce bigger crops on less land, Increasing crop productivity by between 20 and 50 percent. In addition, pesticides allow farmers to maximize the benefits of other valuable agricultural tools, such as high quality seeds, fertilizers and water resources.

How does pesticides affect the food chain?

Beyond direct toxicity, pesticides can significantly reduce, change the behavior of, or destroy populations of plants and animals. These effects can ripple up and down food chains, causing what is known as a trophic cascade. A trophic cascade is one easily-understood example of ecosystem-mediated pesticide effects.

Why do the developing countries prefer using insecticides more than pesticides?

By applying chemicals designed to kill, reduce or repel insects, weeds and diseases harmful to crops, developing countries are producing and exporting more food than ever before. And so is crop intensification: Boosting yields by growing more food on the same area of land inevitably leads to more pesticide use.

How much do pesticides increase crop yield?

Pesticides are used worldwide and increase crop yield on average by 30% as well as improving crop quality.

Do pesticides increase crop yields?

Pesticides—including herbicides, insecticides, and fungicides—have contributed to substantial increases in crop yields over the past five decades. Properly applied, pesticides contribute to higher yields and improved product quality by controlling weeds, insects, nematodes, and plant pathogens.

Do pesticides reduce overall food production?

To date, there is no scientific evidence to show that there is a health risk from eating conventionally grown produce because of pesticide residues, or that organic foods are safer to eat than conventionally produced foods.

Do developing countries use pesticides?

Many developing countries are importing industrial processes that make use of toxic chemicals. By the same token, pesticides, which are toxic by design, are also used increasingly in agriculture and in public health programs to control pests and vector-borne diseases.

How can pesticides help in food preservation?

Pesticides are used to protect crops against insects, weeds, fungi and other pests. Pesticides play a significant role in food production. They protect or increase yields and the number of times per year a crop can be grown on the same land. This is particularly important in countries that face food shortages.

Why do farmers use pesticides on their crops?

Farmers use pesticides to: 1 protect crops from insect pests, weeds and fungal diseases while they are growing 2 prevent rats, mice, flies and other insects from contaminating foods whilst they are being stored 3 safeguard human health, by stopping food crops being contaminated by fungi

How are pesticides used in the transport sector?

The transport sector makes extensive use of pesticides, particularly herbicides. Herbicides and insecticides are used to maintain the turf on sports pitches, cricket grounds and golf courses. Insecticides protect buildings and other wooden structures from damage by termites and woodboring insects.

Who is responsible for food imports and exports?

Food Imports & Exports Under provisions of the U.S. law contained in the U.S. Federal Food, Drug and Cosmetic Act, importers of food products intended for introduction into U.S. interstate commerce are responsible for ensuring that the products are safe, sanitary, and labeled according to U.S. requirements.

Why are farmers forced to export their crops?

Farmers have been likewise forced to switch to export crops when local prices in staples and traditional crops have plummeted as a result of cheap subsidized imports often from the industrialized countries flooding the local markets. For the majority of small farmers, the process has been one of systematic impoverishment.
