在喷洒农药时,一定会遇到药液配制问题。考虑到既安全又有效,在使用一种药剂时或者限定药液浓度,或者限定单位面积上的药量。为此,在使用说明中有以下几种规定。针对成药规定稀释倍数如:防治茄青枯病用14%络氨铜水剂300倍液或50%琥珀酸铜(DT)可湿性粉剂500倍液灌根。即用1升的14%络氨铜水剂加300公斤水或1公斤50%琥珀酸铜可湿性粉剂加500公斤水。由于1公斤水可以等同1升容量,络氨铜是按容量比例配制的,琥珀酸铜是按重量比例配制的。虽然它们都会有一点点误差,但在
Spraying pesticides, we will encounter liquid preparation problems. Taking into account both safe and effective, when using a pharmaceutical agent or to limit the concentration of liquid, or to define the dose per unit area. To this end, there are the following provisions in the use of instructions. Provisions for the drug dilution ratio such as: prevention and control of tomato bacterial wilt with 14% copper aqua regia 300 times or 50% copper succinate (DT) WP 500 times irrigated. That is, with 1 liter of 14% copper aqua ammonia agent plus 300 kg of water or 1 kg of 50% copper succinate WP plus 500 kg of water. As 1 kg of water can be equivalent to 1 liter capacity, copper ammonia is prepared according to the proportion of capacity, copper succinate is formulated by weight. Although they all have a little bit of error, but
