Abstract:
Cross-linking starch xanthate in the presence of biologically active agents such as herbicides, insecticides, fungicides, and nematicides provides particulate products in which the active agent is entrapped within a starch matrix. Active agents can be liquids, solids, or solids dissolved in solvents. Products containing up to 50% by weight of liquid pesticides and more of solid ones have been prepared. By simple modification of the encapsulation process, plastic or elastomeric polymers can be incorporated along with starch xanthate to form products with different release characteristics. Rate of release of the active agents also depends on other selected process variables.
