The embodiment of the present invention is the method adopting Toxicity Determination and field trial to combine.First pass through Toxicity Determination, co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC < 80 is antagonism, 80≤CTC≤120 are summation action, CTC > 120 is synergistic effect, on this basis, then carry out field trial.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration during test, is placed in beaker respectively for subsequent use.Adopt the method connecing worm after first soaking leaf, take out after the blade of the same size not contacting any medicament is soaked 5s in the liquid configured, naturally dry, put into insect box, then connect for examination larva, raise under 25 DEG C of conditions, often process and repeat for 3 times, often repeating examination borer population used is 50, establishes blank simultaneously, checks dead borer population in 72h, calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC
50value.If contrast lethality is greater than 10%, be then considered as invalid test.Computing formula is as follows:
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, and calculate the value of often kind of medicament thus with method of least squares.Co-toxicity coefficient CTC is calculated according to the abundant equation of Sun Yun.Computing formula following (with spiral shell worm ethyl ester for standard agent, its toxicity index is 100):
TI × the P of theoretical toxicity index (the TTI)=spiral shell worm ethyl ester of M
spiral shell worm ethyl estertI × the P of+active component B
active component B
In formula: M is the mixture of different ratio;
P
active component Bfor the ratio that dimehypo is shared in the composition;
P
spiral shell worm ethyl esterfor the ratio that spiral shell worm ethyl ester is shared in the composition.
Note: active component B is arbitrary a kind of in dimehypo, Cupric sulfate, thiocyclam.
Application Example two:
For examination insect: white-backed planthopper.
Experimental scheme: through effective lethal concentration scope of preliminary experiment determination spiral shell worm ethyl ester, the former medicine of dimehypo and the two different ratio mixture.
Toxicity test result one
The toxicity test of table 1 spiral shell worm ethyl ester and dimehypo different ratio Whitebacked Planthopper
As shown in Table 1, spiral shell worm ethyl ester and the composite proportioning of preventing and treating white-backed planthopper of dimehypo exist: when 80: 1 to 1: 80, co-toxicity coefficient is all greater than 120, both explanations mixture in 80: 1 to 1: 80 scopes all shows synergistic effect, especially when spiral shell worm ethyl ester and dimehypo obtain proportioning 10: 1 to 1: 15 time, synergistic effect is more obviously given prominence to, wherein when spiral shell worm ethyl ester and dimehypo weight ratio are 1: 7, co-toxicity coefficient is maximum, synergistic effect is the most obvious, find, spiral shell worm ethyl ester and dimehypo proportioning are 10: 1 simultaneously, 9: 1, 8: 1, 7: 1, 6: 1, 5: 1, 4: 1, 3: 1, 2: 1, 1: 1, 1: 2, 1: 3, 1: 4, 1: 5, 1: 6, 1: 7, 1: 8, 1: 9, 1: 10, 1: 11, 1: 12, 1: 13, 1: 14, composite to control brown planthopper when 1: 15, white-backed planthopper, small brown rice planthopper, trialeurodes vaporariorum, Bemisia tabaci, aphid, scale insect, thrips, rice leaf roller, striped rice borer, paddy stem borer, twill diamond-back moth, cabbage caterpillar, apple leaf miner, beet armyworm, tetranychid, goitre mite, yellow tea mite, the insects such as cotton bollworm also have good synergistic effect, and co-toxicity coefficient is all greater than 170.
