<p>PROBLEM TO BE SOLVED: To provide a safer and high performance perishing and defoliation agent composition to solve various problems such as that a perishing and defoliation effect and an immediate effect are not sufficient since a process dosage is large by a conventional agent, thereby burden to an atmosphere is very large, and an immediate perishing effect is not sufficient, thereby a long time is taken to be perished, and considerable days are required until harvest of a crop.SOLUTION: Even by dosages in which a sufficient perishing and defoliation effect and an immediate effect cannot be obtained each independently, pyraflufen ethyl and carfentrazone-ethyl are used to be combined, thereby unpredictable remarkable synergetic effect is realized, thereby an immediate perishing effect is possessed, and sufficient safety to a crop is possessed by a process dosage that is far lower than respective standard use dosages.</p> |
