Herbicide

A herbicide is a type of pesticide that is used to control or eliminate weeds and unwanted plants. Weeds can be a significant problem in agriculture, competing with crops for nutrients, water, and light, and reducing yields and quality.

How Herbicides Work?

After being absorbed by weeds roots and buds, herbicides act on specific sites and interfere with weeds physiological and biochemical metabolic reactions, resulting in weeds growth inhibition or death.

Now there are many different types of herbicides, but they are usually divided into two categories according to action characteristics: pre-emergence herbicides and post-emergence herbicides.

Pre-emergence herbicides are also called soil treatment herbicides, which can only be used before or during the emergence of weeds. If they are used after the emergence of weeds, they are basically ineffective for weeds.

Post-emergence herbicides is also called stem and leaf treatment herbicide, which are usually used in the vegetative growth period after the emergence of weeds, and are basically ineffective for weeds that have not yet germinated in the soil.
