In the following discussion, pesticides that have been dispersed within the polymer in some way or encapsulated as a solution within a polymeric "skin will be discussed under the "Physically Bonded" topics. These systems are those that physically hold the pesticide within the polymeric matrix. On the other hand, the "Chemically Bonded" systems bind the pesticide or pesticidal ligand to part of the molecule of the polymer itself. Their action is due to either the action of the polymer itself or to the gradual breakdown of the molecule leaving a smaller molecule having pesticidal action. Specialized uses will be found in the sections on "Flocculation Control" and "Spray Drift Control". References that emphasize the incorporation of pesticide-polymers as "Polymeric Devices" and those that control insects and weeds through "Plastic Mulches" will be discussed last. 

E. Plastic Mulch. The use of plain plastic sheeting, with and without a separate application of a pesticide, has many gardening uses. Black plastic mulch has effectively controlled weeds in the vicinity of musk melons and has also served as a barrier for additional herbicide applications to spread to the areas protected by the plastic. Clear plastic mulch raised the soil temperature and when the soil was moist served to kill weed seeds without chemical treatment. The clear plastic also increased growth earliness. ...
