农药对害虫的药效除与药剂性能及施用剂量、害虫种类和虫态以及施药时的环境因素等密切相关外,施用技术和方法如喷雾类型也是一个重要方面。喷雾类型一般可分为3种,即高容量、低容量和微量喷雾,喷液量及雾滴直径依次从大到小。高容量喷雾(即常规喷雾)喷液用量一般为75—150升/亩,雾滴直径为250—1000微米,低容量喷雾一般分别为1—10升/宙和100—200微米,微量喷雾(即超低量喷雾)一般分别为100—250毫升/亩和15—75微米。药剂在靶体(虫体)上的沉积量显然与药效直接
Pesticide efficacy of pesticides in addition to the performance and application of pesticides dose, pest species and insect status and application of environmental factors are closely related, the application of techniques and methods such as spray type is also an important aspect. Spray types generally can be divided into three kinds, namely high-capacity, low volume and trace spray, spray volume and droplet diameter followed by descending order. High-volume spray (ie conventional spray) spray volume is generally 75-150 liters / acre, droplet diameter of 250-1000 microns, low-volume spray are generally 1-10 liters / universe and 100-200 microns, micro spray Namely ultra-low volume spray) are generally 100-250 ml / acre and 15-75 microns. The amount of agent deposited on the target (parasites) is clearly proportional to the efficacy
