LIFE SCIENCE

Detailed explanation-1: -They work fast. They can be removed quickly in critical situations. Herbicides are relatively cheap, and most of the time cheaper than manual weeding. They can destroy plants bearing diseases.

Detailed explanation-2: -For example, exposure to herbicides may lead to elevated internal herbicide concentrations and decreased photosynthesis, cell division, and amino acid production in plants. Effects on aquatic plants can indirectly affect fish and invertebrates by modifying habitat and food availability.

Detailed explanation-3: -herbicide, an agent, usually chemical, for killing or inhibiting the growth of unwanted plants, such as residential or agricultural weeds and invasive species. A great advantage of chemical herbicides over mechanical weed control is the ease of application, which often saves on the cost of labour.

Detailed explanation-4: -They are more resistant to disease. They produce toxins that kill insects but are harmless to humans. They allow farmers to use as much herbicide as they want without worrying about harming the crops.
