Weeds cause yield losses in desired crops through competition for sunlight, water, space, and nutrients. It is important to manage weeds in crop fields and aqua bodies using various management strategies. One of the most effective and efficient ways of managing weeds is through the use of herbicides. However, there is a need to understand the effec...

... herbicides form a seal zone and weed seeds within that seal zone will either not germinate or be killed by the herbicide during germination. The mechanism is called "position/depth protection selectivity" as shown in Figure 1. Selectivity is achieved provided the soil-applied herbicide does not leach easily into the root zone of the crop seed. ...
