SUSTAINED-RELEASE AGRICULTURAL FORMULATION AND CONTROLLING METHOD OF DISEASE AND PEST FOR PADDY RICE USING THE SAME

摘要

The present invention provides a method for controlling the major disease and pest injuries during the paddy rice culture period just one dose of the pesticide before transplant, resulting in the reduction of the farmers' labor and the discharge amount of chemical materials to the environment.
