Next, it is used to determine the synergism of the bioinsecticide mixture and field tests. Field tests compared the efficacy of bioinecticide on the population and intensity attacks and crop yields. The results of the research were: bioinsecticide, a mixture of neem and lemongrass leaf extracts, was more toxic than those used alone, and has a synergistic impact. The population, intensity of attacks  and yields compared to Imdakloprid were not significantly different.
