Abstract

Herbicides affect not only the weeds present in a crop, but also the crop itself. In the absence of weeds, both positive and negative responses to herbicides have been reported in the literature. The negative responses are the most important, especially if yield is decreased below the economic threshold for herbicide use. Factors which are important in determining the level of crop response to a herbicide include the crop species and variety, the timing of the herbicide, the rate of herbicide and the environmental conditions under which the crop is growing.
