What are agri-chemicals?
Chemicals like herbicides, pesticides and fungicides, that are used on crops on farms.
How do farmers grow GM food?
GMO foods are grown very much like non-GMO that are not being grown organically. The big difference is that some of the crops have been engineered to have resistance to herbicides like Round-up. For those crops, the herbicide can be sprayed directly on the crop without killing it; whereas, it cannot be sprayed directly on the non-GMO crops. Other crops have been genetically engineered to produce a substance that kills insects when they eat the plant. In that case, those growing GMO crops theoretically would not need to use pesticides, or at least not as many pesticides, as those who grow non-GMO crops.
Is an organically grown crop really organic if seed is GMO or not from organic crop?
No. The National Organic Program guidelines prohibit use of GMO seeds for crops labeled "organic". GMO crops can't be sold as organic produce. However, if a crop is grown without synthetic fertilizers, pesticides, fungicides, or herbicides, it's "organic", it just can't be labeled or sold as organic.
What type of pesticides do chemistry design to protect crops?
Chemists design a variety of pesticides to protect crops, including insecticides to kill insects, herbicides to control weeds, fungicides to combat fungal diseases, and bactericides to control bacterial infections. They work to create effective and environmentally safe solutions to help farmers protect their crops from pests.
How does biological control and genetic modification be used instead of pesticides and herbicides to control pests that destroy crops?
Biological control involves using natural enemies of pests, such as predators or pathogens, to keep pest populations in check. Genetic modification can be used to engineer crops that are resistant to pests, reducing the need for chemical control methods. These approaches can be more environmentally friendly and sustainable than using pesticides and herbicides.
What are chemicals that kill crop-destroying organisms?
Pesticides such as insecticides, herbicides, and fungicides are chemicals commonly used to kill crop-destroying organisms like insects, weeds, and fungi. They are applied to crops to protect them against pests and diseases.
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".
What are some domestic uses for sprayers?
A sprayer is a device used to spray a liquid. It can be used in agriculture, a sprayer is a piece of equipment that spray nozzles to apply herbicides, pesticides and fertilizers to agricultural crops.
Should pesticides be used to produce more food?
no because pesticides can also kill some crops, they are also harmful to the human body
Pesticides are a family of chemicals?
Pesticides are substances used to control pests like insects, weeds, and fungi that can harm crops. They can include insecticides, herbicides, and fungicides, among others. These chemicals are designed to target specific pest populations while minimizing harm to other organisms and the environment.
What are the uses of herbicides?
herbicides are used to destroy weeds or fungi which may destroy or cause the crops to get diseases.
Name products which are made from organophosphorus compounds?
Some products made from organophosphorus compounds include pesticides, herbicides, and nerve agents. These compounds are commonly used in agriculture to protect crops from pests and weeds, as well as in chemical warfare.
