棉油乳剂的性能,常因制造方法不一样,所以它们的效果也不相同。书本上的记载和现今群众所用的棉油乳剂,种类很多,在这些棉油乳剂当中,究竟以那一种的性能最好?杀虫效力大小如何?有没有药害作用?这都是些需要明确的问题。因此我们采用了六种乳剂,做了一个性能比较试验,目的在测定固体棉油乳剂在各种棉油乳剂中的地位和它的前途,结果如下列四表:
The performance of cotton oil emulsion, often due to different manufacturing methods, so their effect is not the same. There are many types of cotton oil emulsions used in today’s books and books. What is the best performance among these cotton oil emulsions? How effective are insecticidal effects? Is there any harm to medicine? Clear question. Therefore, we used six emulsions and made a performance comparison test to determine the status of solid cotton oil emulsion in various cotton oil emulsions and its future. The results are shown in the following four tables:
