Depends on what you want to use them for. I have used lavender and or tea tea to wash my hands after gardening for years. When you work in the dirt and around plants your skin sustains lots of small superficial scratches and gouges, since I started using the lavender wash I have not had a single problem with the scratches swelling and/or turning red.
Herbicides work by disrupting essential processes in plants, such as photosynthesis or growth regulation, leading to their death. They are designed to selectively target plants while being safe for non-target organisms. Herbicides can be applied directly to the plant or to the soil to prevent weed growth.
Herbicide is a 'chemical or biological agent which kills plants or inhibits their growth' (The Macquarie concise dictionary, 3rd Ed.)
For herbicides there are two methods to consider,
1. Contact herbicides kill the living plant tissue they come in contact with, they are fast acting.
2. Translocated herbicides are absorbed into the plant and move through-out the plant disrupting different functions with in the plant. These chemicals are slow acting.
3. Physiologically, most of the herbicides inhibit ALS (Aceto lactae synthase) thereby disrupt the synthesis of vital aminoacids that are important for the cell division and growth of cells. The plant gradually dies due to this
The chemical inhibits or interrupts the weed's biological processes or enzyme production. The way they work is referred to as "mode of action," and there are 11 primary modes of action which would include most herbicides commonly used in the US. See the related link below for more information.

The chemicals which prevent the growth of unwanted plants are?
These chemicals are called herbicides. They work by disrupting essential plant processes, such as photosynthesis or growth regulation, effectively killing or inhibiting the growth of unwanted plants without harming desired crops or vegetation.
What are the commercial uses of auxins?
they are sometimes used as herbicides ...
How are herbicides classified?
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.
How are herbicides designed to harm plant cells but not human cells?
Systemic and target-specific formulations are ways in which herbicides are designed to harm plant -- not human -- cells. But in reality, it is difficult to comprehend and control all of the after- and side-effects of herbicides so environmentalists tend to speak of degrees of ambient residue and of harm to non-target organisms.
Examples of insecticides?
Some common examples of insecticides are pyrethroids (e.g. permethrin), organophosphates (e.g. malathion), carbamates (e.g. carbaryl), and neonicotinoids (e.g. imidacloprid). These insecticides are used to control pests on crops, in homes, and for public health purposes.
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 some of the most effective herbicides available?
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.

What are chemical herbicides?
Chemical herbicides are weed killers made in the laboratory, not from nature.
The chemicals which prevent the growth of unwanted plants are?
These chemicals are called herbicides. They work by disrupting essential plant processes, such as photosynthesis or growth regulation, effectively killing or inhibiting the growth of unwanted plants without harming desired crops or vegetation.
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 use herbicides?
People use herbicides to control or eliminate unwanted vegetation, such as weeds, in agricultural fields, gardens, and lawns. Herbicides help increase crop yields by reducing competition for nutrients, water, and sunlight.
