Annotate: the malicious factor 〉=+20 expressions have synergistic effect altogether, and≤-20 expressions have antagonism ,-20～+ 20 expression summation actions.
Reagent agent the results are shown in following table 1 to the Toxicity Determination of Spodoptera litura larvae:
Table 1
The result of indoor bioassay shows that the common malicious factor behind two kinds of composite reagents of Spodoptera litura nucleopolyhedrosis virus and worm hydrazides is 56.32, and the lethal concentration of 50 (LC of its mixture preparation
50) obviously little than the agent of pure worm hydrazides list, show significant synergistic effect.From table, it can also be seen that the LT of embodiment 1 and 2 medicament
50LT than viral single agent
50Two days have been shortened.Illustrate that the present invention both can reduce dosage, can quicken the quick-acting of medicament again.
Biological Examples 2:
Field efficacy for checking embodiment medicament 1 and 2, respectively on August 10th, 2008 in Mt vegetables field, Baiyun District, Guangzhou City with carried out the field control effectiveness test of these two kinds of medicaments on August 14th, 2008 in the pure and fresh vegetables of Qingyuan City base, adopt five point samplings, investigation in 3 days, 5 days, 7 days, 14 days borer population alive adopts following formula to calculate control efficiency behind medicine.
The embodiment medicament sees Table 2 to the field efficacy measurement result of Spodoptera litura larvae:
Table 2
As can be seen from the above table, Spodoptera litura nucleopolyhedrosis virus and worm hydrazides are composite shows very outstanding control action to prodenia litura.Behind the medicine 3 days, embodiment 1 and 2 medicament reached 65.4%, 67.3% respectively to the preventive effect of prodenia litura, a little less than the preventive effect of worm hydrazides list agent, but obviously are better than the single agent of prodenia litura virus; Behind the medicine 5 days, embodiment 1 and 2 drug effect reached the highest, and its preventive effect is respectively 85.6% and 83.2%, is significantly higher than the preventive effect of list agent of worm hydrazides and the agent of Spodoptera litura nucleopolyhedrosis virus list.Behind the medicine 14 days, embodiment medicament 1 and 2 drug effect still remained on more than 60%.
