If co-toxicity coefficient is more than 120, it was shown that have potentiation; If lower than 100, it was shown that for antagonism; Between 100 ~ 120, it was shown that for summation action.
Table 2
From the data of table 1 it can be seen that when the proportioning of pyraclostrobin and inabenfide is within the scope of 1:100 ~ 100:1, co-toxicity coefficient is all higher than 120, this shows that both compound drugs are preventing and treating the effect achieving gain in wheat rust.
(3) anti-fall volume increase test
For planting experimentally son: corn seed (Zheng Dan 958)
Reagent agent: inabenfide, pyraclostrobin
Test method: average division of cells, every plot area about 100 square metres, maize planting, controls line-spacing and is about 40-50cm, spacing in the rows 30-40cm. At the Semen Maydis jointing initial stage, pharmaceutical agent combinations shown in table 3 processes and Semen Maydis is carried out spraying process respectively, and spray liquor consumption controls about 40 liters/mu. In harvest time, measure average height and the per mu yield of each process Semen Maydis respectively. Result is shown in table 3 below.
Table 3 corn trials
As can be seen from Table 3, compareing relative to clear water, Semen Maydis plant height is had certain control action by inabenfide, and pyraclostrobin is without obvious control action; And after inabenfide is mixed with pyraclostrobin spraying, relative to inabenfide, it is possible to substantially reduce Semen Maydis plant height further, this lodging tolerance being conducive to improving Semen Maydis. Same, inabenfide mixes application with pyraclostrobin, compares relative to each single dose and clear water, it is possible to substantially increase Semen Maydis per mu yield.
The composition pesticide of the present invention is described already by specific embodiment. But examples detailed above is only being explained further the present invention, is not limitation of the invention, by the scheme simply adjusted by such scheme and then obtain, it does not have depart from the spirit of the present invention, be regarded as being included within the scope of the present invention.
