Fungicidal composition of the present invention has the following advantages: have good synergistic function, improve the control efficiency to corps diseases, can also enlarge fungicidal spectrum, delay the pathogen pesticide resistance and occur.
Embodiment
The present composition can illustrate by following example the synergistic function of harmful fungoid, but the present invention only limits to absolutely not these embodiment.
Method of testing:
Take by weighing an amount of reactive compound acetone solution, water is mixed with each compound the solution (content of acetone is not more than 10% in the solution) of described concentration.The emulsifier Tween 80 of 0.1% (volume) is added in this solution, by described proportioning each reactive compound equal proportion is mixed, obtain described proportioning and concentration.
Infect percentage evaluation by measuring leaf area.These percentages are changed into effectiveness.Use the Abbot formula to calculate and render a service (W), namely obtain the effectiveness of observing:
W＝(1-α/β)×100
In the formula:
α: the fungal infection percentage of processing plant;
β: the fungal infection percentage of (blank) plant of being untreated;
Render a service as " 0 " and represent that the level that infects of processing plant is identical with the level that infects of untreated control plant; Render a service as " 100 " represent to process plant and infected.
The expection of composition render a service use the Colby formula (see R.S.Colby, weeds (Weeds), 1967,15,20-22) determine and with the effectiveness of observing relatively:
E＝x+y-xy/100
In the formula:
E: (effectiveness of the calculating in following each table) is renderd a service in the expection when working concentration is the composition of the active component A of a and b and B, represents with the % of untreated control;
X: the effectiveness when working concentration is the active component A of a represents with the % of untreated control;
Y: the effectiveness when working concentration is the active component B of b represents with the % of untreated control.

Application Example 4 control wheat sharp eyespot (Rhizoctonia cerealis) tests, conservation treatment
Cultivar is sprayed to the drip point for the potted plant wheat seedling leaf of " temperature six " with active component concentration aqueous suspension as described below.After 24 hours, be inoculated in test plants with the rhizoctonia cerealis cake.Place 22～24 ℃ to be that 85～90% climatic chambers are regulated 7 days with relative atmospheric humidity test plants.Then naked eyes are measured the development degree of infection process on the leaf.The activity data of the active component that each is independent and present composition control wheat sharp eyespot the results are shown in Table 7 and table 8.
