Important Fact about Herbicides Herbicides are further divided into three broad categories of pre-emergence, pre-plant and post emergence on the basis of time of application. Depending upon the chemical nature of herbicide, age and characteristics of weeds, and other factors, timing of herbicide application is decided. Pre-plant herbicides are applied before the crops are grown. Pre-emergence herbicides are applied before the emergence of weeds and after the plantation of the crops and post emergence herbicides are used after the weeds have emerged.
