The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Earlier by Toxicity Determination, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC＜80 are antagonism, and 80≤CTC≤120 are summation action, and CTC＞120 are synergistic effect, on this basis, carry out field trial again.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration during test, places beaker standby respectively.Adopt and to soak the method that connects worm behind the leaf earlier, the blade of the same size that does not contact any medicament soaked in the soup that configures behind the 5s take out, dry naturally, put into insect box, connect then for the examination larva, under 25 ℃ of conditions, raise, every processing repeats for 3 times, every to repeat used examination borer population be 50, establishes blank simultaneously, checks dead borer population in 72h, calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate the LC50 value.If the contrast lethality then is considered as invalid test greater than 10%.Computing formula is as follows:
The insect corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (be standard medicament with the Tolfenpyrad, its toxicity index is 100):
TI * the P of theoretical toxicity index (TTI)=Tolfenpyrad of M
TolfenpyradTI * P of+effective active composition B
Effective active composition B
In the formula: M is the mixture of different proportionings
P

As can be seen from Table 4, can effectively prevent and treat rice hoppers after Tolfenpyrad and butyl ether urea are composite, control efficiency all is better than the preventive effect of single agent, and the preventive effect time is long.In the test scope of medication, the target crop is had no adverse effects.
After draw through different local throughout the country tests, Tolfenpyrad and butyl ether urea composite afterwards to the preventive effect of insect pests such as rice fulgorid, aphid, Bemisia tabaci, trialeurodes vaporariorum, tea lesser leafhopper, two spotted spider mite all more than 95%, be better than single agent preventive effect, synergistic effect is obvious.
