多年来,在果树生产中,特别是6～8月份多雨季节,是果实发病率最高、虫害最严重的时期,因此雨季合理使用农药至关重要。一、选用速效性、杀伤率高、击倒力强的农药。如灭扫利、来福灵、速灭杀丁等。使用2～4小时后便可杀死害虫,可避免慢性农药因雨天药效流失的弊端。二、选用内吸性较高的农药。如氧化乐果、久效磷、辛硫磷、甲胺磷等杀虫剂和甲基托布津、速保利、粉锈宁、三环唑等杀菌剂,这些农药使用后4～6小时便有60%以上的有效成份被果树吸收到组织器官
Over the years, the fruit tree production, especially in June-August rainy season, is the highest incidence of fruit, pests most serious period, so the rational use of pesticides during the rainy season is crucial. First, the selection of quick, killing rate, knockdown pesticides. Such as exterminating Lee, Laifouring, speed kill Kill and so on. Use 2 to 4 hours to kill pests, to avoid the shortcomings of chronic pesticide loss due to rainy days. Second, the use of higher absorption of pesticides. Such as omethoate, monocrotophos, phoxim, methamidophos and other insecticides and thiophanate-methyl, speed poly, triadimefon triadimefon and other fungicides, these pesticides 4 to 6 hours after the use of 60% The above active ingredients are absorbed into the tissues and organs of fruit trees
