Description

Selective herbicides have become an integral component of modem crop production systems. These herbicides are selected for their ability to control important weeds without causing significant injury to the crop. Although the margin of crop safety varies widely among products on the market, it has generally been accepted that these products will not impact crop yield potential when used according to label and under 'favorable' environmental conditions. However, increasing numbers of persons are beginning to question the validity of this assumption. Several factors are responsible for these concerns, including changes in herbicide use patterns, introduction of herbicide resistant crops that may have the potential to eliminate injury concerns, and the growing popularity of yield monitors which provide an easy means to make yield comparisons. This paper will discuss some of the recent issues concerning herbicide injury.
