Pest control agents, economic plants

Examples 3 and 4 illustrate a potential application of allelo-pathic chemicals in today s agricultural practices, as illustrated in Figure 3 to plant allelopathlc plants as a cover crop in the field, especially for tree crops such as peach and citrus. Such plants produce allelopathlc chemicals to control soil pests such as nematodes. This approach will be appreciated today, because there is no effective agent to control soil pests on a field scale and, as has been noted, there is no economic incentive for a chemical company to develop a minor-crop pesticide.
