Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, the embodiment
It is only used for explaining the present invention, is not intended to limit the scope of the present invention..
The toxicity test of the paichongding of embodiment 1 and rotenone single dose and both mixtures to planthopper
Subjects：Planthopper
Test method：Test method refers to《Magnificent people's republic's agricultural industry criteria NY/T1154.7-2006》.Experiment
Planthopper used is planthopper (brown paddy plant hopper) pupa for picking up from field, and the indoor rice seedlings of temperature raised for 3 generations, selected uniformity
Four-age larva, it is put into the culture dish (diameter 12cm) for having put rice seedling (being handled with cotton ball moisturizing), is connect per ware numb
Liquor-saturated larva 30, often processing connect 4 culture dishes, the dispenser into culture dish in a manner of spraying by single dose and mixture, are sprayed per ware
Liquid 3ml, after insect revives, by treated culture dish be put into 27 DEG C, the photoperiod be to be cultivated in 16h/8h incubators, 72 hours
Dead borer population is checked, calculates the death rate, blank control spray equivalent clear water, 72h checks death toll, and it is dead to calculate correction with Abbott formula
Rate is died, calculates the LC of each medicament50Value, activity of the reagent agent to larva is evaluated with this.Specific calculation formula is under this：
Single dose paichongding is set as standard single dose, it is 100 to specify its toxicity index (TI), then single dose rotenone, bigcatkin willow oxime
The toxicity index (TI) of acid and mixture (paichongding, rotenone and bigcatkin willow oxime acid) is respectively：
Percentage of the TI × single dose of the theoretical toxicity index (TTI) of mixture=each single doses of Σ in mixture
Pesticidal combination containing paichongding the results are shown in Table 1 to the virulence of planthopper.
Table 1
As it can be seen from table 1 paichongding：The proportioning of rotenone is in 75-90：When in 10-15 scope, it is to planthopper
Co-toxicity coefficient is all higher than 120, illustrates that both show as gain effect at mixture in the range of this.
Synergistic effect of the bigcatkin willow oxime of embodiment 2 acid (SHAM) to mixture
Table 2
| Medicament | LC50(ug/mL) |
| Active component (paichongding：Rotenone=80：12). | 9.79 |
| Active component (paichongding：Rotenone=80：12)：Bigcatkin willow oxime acid=95：5 | 6.91 |
| Active component (paichongding：Rotenone=80：12)：Bigcatkin willow oxime acid=99：1 | 8.34 |
