Random 5 points of samplings per cell in one week, per takes 1m duplicate rows and investigates total spike number and dead ears number, is repeated 4 times.
Dead ears rate=dead ears number/total spike number × 100%；
Prevention effect=（Control dead ears rate one processes dead ears rate）/ control dead ears rate × 100%.
Prevention effect of 1 embodiment of the present invention 1-9 antibacterial of table to take-all
As shown in Table 1, compared to positive control, each raw material Synergistic of antibacterial of the present invention, embodiment of the present invention 1-9 antibacterial
To take-all preventive effect up to 80%, comparative example 1 is added without plant extraction liquid, and comparative example 2 does not adopt CGA-173506 original
Medicine, comparative example 3 does not adopt (-)-Stemoninine and tea saponin, and prevention effect is then decreased obviously, and illustrates that each raw material collaboration of the present invention is made
Use effect is significant.
