Herbicides kill plants and insecticides kill insects. Sometimes they kill other things such as animals and fish as well.
As they travel downstream they may harm wildlife and wild animals. If they get into the water supply used by humans they could be poisoned too.
We rely on the balance of nature for many predators to be killed off. Many insects naturally prey on other insects. If an insect that damages plants does not have its numbers limited by the insect that preys on it it will carry our more damage than usual and may do more damage than the plants can recover from. Once the balance of nature is lost it is difficult to exactly work out what the consequences might be.
Some problems are:
- contamination of soils and waters
- contamination of foods
- killing non selective some useful plants or sometimes insects
- intoxication of workers and animals

What are the benefits of using herbicides?
weeds compete with the crop for water, nutrients, sunlight and space. using herbecides gives your crops a better chance for survval

What is the negative consequence of using pesticides and herbicides?
It doesn't taste nearly as good, even after you wash it, and it's not as healthy for you or the environment.
What are chemical herbicides?
Chemical herbicides are weed killers made in the laboratory, not from nature.
How do you kill gorse bushes?
To kill gorse bushes, you can physically remove them by cutting them at the base or using machinery to uproot them. Chemical herbicides can also be used, but this method requires caution and follow-up monitoring to prevent regrowth. Make sure to check local regulations before using herbicides.
What is the source of herbicides?
Herbicides can be synthetic chemicals or natural substances derived from plants. Synthetic herbicides are typically manufactured in laboratories, while natural herbicides may come from sources like vinegar, citrus oils, or plant extracts. Herbicides work by targeting and killing unwanted plants, helping to control weeds in agricultural or landscaping settings.
What are the uses of herbicides?
herbicides are used to destroy weeds or fungi which may destroy or cause the crops to get diseases.

What do general herbicides do?
Herbicides are members of the group of pesticides; thet are used to kill plants unwanted by the human beings.
Why do people think non-organic food are bad?
Non-organic agriculture causes environmental and health problems. This is because these crops are grown using toxic insecticides, herbicides, and fertilizers. The chemicals enter the environment, poisoning many organisms. When we eat these foods, we end up eating trace amounts of these chemicals, which accumulate over time and can cause a multitude of health problems, including cancer.
