Proper management of the plants, the fish and other organisms that make up the aquatic ecosystem increase the value of the water body to all users. Fisheries depend on plants for several things. The most widely recognized need is that the plants provide cover for small fish from predators. At the same time, the aquatic habitat supports an array of organisms that all of the fish utilize as a food source. Plants provide oxygen that the fish and other organisms need to survive.
Plants also provide a filtering capability that contributes to the clarity of the water.
Cerexagri further believes that it is environmentally irresponsible to routinely conduct whole-lake herbicide treatment, regardless of how serious the aquatic plant problem. This provides the advantage of being able to control the area of plants where the application is placed. This is important when the amount, type and location of the plant populations must be managed to preserve their value to many interests. Because of the nature of their actions, systemic herbicides often control significantly more area than initially applied. Selectivity Cerexagri has conducted research in both southern and northern latitudes to determine the selectivity of its products.
