Herbicides work in many different ways. If we understand a herbicide’s mode of action, we will know what symptoms it produces at lethal or sub-lethal doses. Other problems such as disease, nutrient deficien-cy, and insect damage may mimic the effects of her-bicides.

Herbicides are chemicals that kill plants or inhibit their normal growth. Their means of doing this are varied and theoretically as numerous as the processes essential to plant life. Herbicides are most often and most effectively used together with good cultural practices in a turf weed management program.

They work in many different ways. In order to be effective, herbicides must first be applied to a plant. After the herbicide is applied, it must then be retained on the leaf's surface. Then it must move through the water filled space that is around the cell.

How herbicides work?; Herbicides work in many different ways. In order to be effective, herbicides must first be applied to a plant. After the herbicide is applied, it must then be retained on the leaf and penetrate the waxy cuticular layer that is on the leaf’s surface.

Depending on the situation, early treatment of cereals can help to avoid work peaks later in the season. Resistance; Limiting the rotation to one or two crops, and intensive use of herbicides with identical or similar modes of action, favour the development of resistance in weeds.
