Chemical herbicides are weed killers made in the laboratory, not from nature.

A herbicde is a chemical that kills plants (wedkillers etc.). Herbicides are generally manufactured by chemical industries, not grown as crops. Herbicides are used worldide for peaceful (pest control) and war oriented (defoliants) purposes.
"Chemical method" is another way of saying to use appropriate herbicides for weed control.
Herbicides are classified based off many different qualities and properties. These qualities and properties include activity, use, chemical family, mode of action, and controlled vegetation type.

To general of a question. So the answer is no. Not every chemical is hazardous to plants. ---------------------------------------------- Some chemical are good for plants and some are bad - you need to tell us which you want to know about. There are some chemical (weedkillers) that are specifically designed to kill plants.
Organic foods have been grown since the beginning of time, long before chemical fertilizers, herbicides, pesticides, and other chemical pest controls were introduced.
Herbicide is a chemical substance used to kill unwanted plants or weeds. When herbicides enter water sources through runoff or leaching, they can contaminate the water and harm aquatic plants and animals. Herbicides can disrupt ecosystems and affect water quality.
No a caterpillar is not a herbicide it is the common term for the larval stage of a moth or a butterfly. A herbicide is a chemical or substance that kills plant materials. Normally if you wanted to kill caterpillars you would use an insecticide.
The most effective herbicides available are systemic herbicides. These herbicides travel all the throughout the plant, including to its roots. They tend to take a slightly longer time than other herbicides but are much more effective.
Some herbicides can be harmful to pets. In fact, herbicides account for two of the top ten accidental poisonings for pets. Some of the most dangerous herbicides are ones that contain ���disulfoton�۝. Disulfoton pesticides can cause vomiting, diarrhea, seizures, and potentially death. What makes it worse is that dogs are drawn to disulfoton pesticides and will eat as much of it as they can get a hold of. Slug and snail bait can cause tremors, seizures, and death and they also tastes good to dogs. Other types of chemical herbicides can be less dangerous but are still risky for pets to consume and will often cause your pet to vomit.
