Abstract
The invention discloses a fungicidal composition for prevention and treatment of crop diseases. The fungicidal composition contains two active components, i.e. zincpolyanemine and pyraclostrobin, wherein the weight ratio of the zincpolyanemine to the pyraclostrobin is (10-30): (1-30). The invention also discloses the applications of the fungicidal composition for the prevention and treatment of crop diseases in preventing and treating diseases such as wheat powdery mildew, anthracnose of tomato, grape anthracnose, powdery mildew and rice blast. The fungicidal composition can produce a good synergistic effect and overcome and delay the disease resistance of diseases, the prevention and treatment spectrum is expanded, the drug cost is lowered, and the environment pollution is reduced.

Experimental example 1:
This experimental example is field efficacy Application Example.
Raw survey adopts mycelial growth rate method, and observed result after 5d, calculates the indexs such as the EC50 of each formula, co-toxicity coefficient, the co-toxicity coefficient method representation that the co-toxicity of mixture preparation adopts Sun Yun abundant:
The theoretical toxicity index A=∑ of mixture preparation (percentage of this pharmaceutically active ingredient of the toxicity index of certain medicine × in mixture)
Be synergistic effect when CTC is greater than 120, being antagonism when being less than 80, is addition during 80-120.
Table 1 pyrithione zinc, pyraclostrobin and different the raw of pairing comparison wheat powdery mildew thereof survey result
As can be seen from the above-mentioned raw data result surveyed, pyrithione zinc and pyraclostrobin composite time all have synergistic effect, the co-toxicity coefficient (CTC) of formula is all greater than 120, illustrate pyrithione zinc 10%-40% and pyraclostrobin 5%-20% scope in composite, have obvious synergistic effect.
For verifying the practical effect of complex preparation control corps diseases further, with wheat powdery mildew, anthracnose of tomato, bitter rot or anthracnose of grape, powdery mildew, rice blast is that controlling object carries out field trial.Concrete diluted concentration is arranged: embodiment one 1000 times of liquid, embodiment 2 1500 times of liquid, embodiment 3 1000 times of liquid, embodiment 4 3000 times of liquid, 25% pyraclostrobin missible oil 2000 times liquid, 30% pyrithione zinc wetting powder 800 times liquid, separately establish blank totally 7 process, often process repetition 2 times, repeat area 100 square metres, respectively at the their early stage of each disease of crops, with above each embodiment and the extension rate contrasting medicament, every 666.7 square metres of amount of liquid medicine are 50 kilograms, thin spraying is watered with backpack mist sprayer, after one week, medication is once again, within 7 days after second time medicine, investigate each process disease index, and calculate relative control efficiency with the disease index of check plot.Its result is as table 2:
Embodiment one, embodiment two, embodiment three, embodiment four all obtain good control efficiency, and preventive effect is all high than 30% pyrithione zinc, 25% pyraclostrobin.
The field test effect of table 2 pyrithione zinc and pyraclostrobin and different ratio thereof
As can be seen from above-mentioned data, the field efficacy of embodiment one, example two, example three, example four all higher than or be equal to 25% pyraclostrobin, be significantly higher than the result of use of 30% pyrithione zinc single dose, not only there is a medicine control more, expand fungicidal spectrum, and can prevent or delay the drug-fast generation of pyraclostrobin single dose, more obviously reduce the pesticide cost using pyraclostrobin single dose, cost performance is high, the present invention with water or kaolin etc. for matrix, environmentally safe.So R&D and promotion of the present invention has great importance.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
