The invention relates to a compound pesticide for protecting and curing rice sheath blight, which belongs to the technical field of compound pesticides. The compound pesticide is characterized by containing 0.15-25 percent of thifluzamide and 1-50 percent of validamycin. The compound pesticide for protecting and curing the rice sheath blight is prepared by compounding the thifluzamide and the validamycin and has good protecting and curing effect; and field trials shows that the protecting and curing rate of the compound pesticide can reach 98 percent. The compound pesticide has strong persistence and prolongs the period of validity of protecting and curing the rice sheath blight to be 30 days; and the production cost of the compound pesticide is lower and is reduced by more than 50 percent compared with a pesticide which singly uses the thifluzamide.
