多年来,苹果生长期防治炭疽病的常用农药大多是保护剂,不耐雨水冲刷,防治效果不太理想,苹果炭疽病的发生危害仍较严重。我们经1983—1985年田间药效试验证明:80%大富丹可湿性粉剂是防治苹果炭疽病较为理想的药剂。大富丹是由美国雪弗龙化学公司研制,日本东棉株式会社经销的果树、蔬菜等作物的保护杀菌剂。此药对人畜和植物安全(对鱼类有毒),无慢性毒性,能与多种农药混合,但不能与强碱性农药混用。其最大特点是药液不易被雨水冲刷,反而有利于药
Over the years, most of the commonly used pesticides for preventing and curing anthracnose in the apple growing season are protective agents, which are not resistant to the erosion of the rain water. The control effect is not very satisfactory and the occurrence of apple anthracnose is still more serious. Our 1983 to 1985 field efficacy trials proved that: 80% of the DUDAN wettable powder is an ideal agent to control apple anthracnose. Dafu Dan is the United States Chevron Chemical Company developed by the Japanese East Cotton Co., Ltd. distribution of fruit trees, vegetables and other crops fungicides. It is safe for humans, animals and plants (toxic to fish), is not chronically toxic, can be mixed with multiple pesticides, but can not be used with strong base pesticides. Its most prominent feature is the liquid is not easy to be washed away by rain, but is conducive to medicine
