Abstract
The invention relates to a sterilizing composition containing azoxystrobin and zineb and application thereof. The composition comprises the azoxystrobin and the zineb, wherein the weight ratio of the azoxystrobin to the zineb is 1-50:1-50. The composition can be used for preventing and controlling crop diseases such as cereal crops, melons and fruits or vegetables and the like. The composition has a wide applicable range, good effect, low cost and low residue and is safe to human, livestock, environment and the like.
Description
(1) technical field
The present invention relates to a kind of bactericidal composition and purposes, relate in particular to a kind of bactericidal composition that contains Fluoxastrobin and zineb and uses thereof.
(2) background technology
Fluoxastrobin (Azoxystrobin) is first commercial methoxy acrylic bactericide, and fungicidal spectrum is wide, and the bactericidal activity height has protection, roots out, systemic activity.The mechanism of action of Fluoxastrobin is to stop the ATP of cell synthetic by the electronics transmission that suppresses between cytochrome b and the c1, thereby suppresses mitochondrial respiratory.Nearly all mycota (Ascomycotina, Basidiomycotina, Mastigomycotina and Deuteromycotina) disease such as powdery mildew, rust, glume blight, net blotch, downy mildew, rice blast etc. all there is good activity.It does not have cross tolerance to 14-demethoxylation enzyme inhibitor, benzamides, dicarboxylic dihydrazides amine and benzimidazole.Fluoxastrobin can be used for cauline leaf spraying, seed treatment, also can carry out soil treatment, be mainly used in cereal, paddy rice, peanut, grape, potato, fruit tree, vegetables, coffee, lawn etc., can effectively prevent and treat powdery mildew, rust, glume blight, net blotch, downy mildew, rice blast, anthracnose, banded sclerotial blight, alternaria leaf spot of apple, pear scab or the like various crop disease.
At present this product list agent use cost is too high, not general as yet large tracts of land and promoting the use of.
Zineb (Zineb) is a protection bactericide, and its mechanism of action is to destroy coacetylase, thereby influences oxidation of fatty acids.Many germs such as Pseudoperonospora cubensis, late disease bacteria and anthrax bacteria etc. there is stronger action of contace poison.The active ingredient chemical property is more active, in water, easily be oxidized to different thiocyanation compound, to the cause of disease thalline contain-enzyme of SH base has stronger inhibitory action, and the direct kill pathogens spore of energy, suppress the germination of spore, stop in the germ invaded plants body, but less to the mycelial lethal effect of cause of disease in the invaded plants body.
Because the service time of zineb is very long, many crop pests have produced resistance to it, make drug cost increase gradually, but drug effect are really more and more undesirable.
(3) summary of the invention
One of purpose of the present invention is to overcome above-mentioned deficiency, provide a kind of applied widely, effective, cost is low, the residual low bactericidal composition that contains Fluoxastrobin and zineb.
Two of purpose of the present invention is to provide a kind of purposes that contains the bactericidal composition of Fluoxastrobin and zineb.
The object of the present invention is achieved like this:
A kind of bactericidal composition that contains Fluoxastrobin and zineb, described composition contains Fluoxastrobin and zineb, and the weight ratio of described Fluoxastrobin and zineb is 1～50: 1～50.
The optimization weight ratio of described Fluoxastrobin and zineb is 5～30: 5～40.
The weight ratio of described Fluoxastrobin and zineb is 1: 5,1: 10,1: 15,1: 20,1: 25,5: 1,10: 1 or 15: 1.
Described combination dosage form is any one formulation that allows on the agricultural chemicals.
Described combination dosage form is wetting powder, water dispersible granules, suspending agent, aqueous emulsion or missible oil.
Described Fluoxastrobin and the zineb mass percent in composition is 5～90%.
A kind of purposes that contains the bactericidal composition of Fluoxastrobin and zineb is used for the medicine as cereal crop, melon and fruit or vegetable crop disease.
Be used for medicine as apple anthracnose.
Compared with prior art, the invention has the beneficial effects as follows:
(1) present composition good synergistic effect of performance in certain ratio range;
(2) the mechanism of action difference of two kinds of active components among the present invention, the application of composition can delay or overcome the resistance of pathogen, prolongs the service life of product;
(3) present composition fungicidal spectrum has enlarged, can be used for preventing and treating the disease of crops such as cereal crop, various melon and fruit, vegetables, crop pests such as paddy rice, wheat, tomato, banana, apple, watermelon particularly are as rice blast, wheat powdery mildew, early blight of tomato, sigatoka, alternaria leaf spot of apple etc.;
(4) bactericidal effect of the present composition has had than single agent and has significantly improved, and has reduced agricultural chemicals using dosage and cost simultaneously, has reduced residually, has also alleviated the harmful effect to environment.
(4) embodiment
Clearer in order to be purpose of the present invention, technical scheme and advantage, the present invention describes with following instantiation, but the present invention is not limited to these examples.
The present composition is an active ingredient with Fluoxastrobin and zineb, finds through the indoor bioassay test, and antagonistic drug venereal disease evil had obvious role in synergism after both were composite, specifically was illustrated with following biologicall test example.
The example of measuring in kind: the composite toxicity test of Fluoxastrobin and zineb to apple anthracnose
1, subjects: apple anthracnose
2, test method:, adopt the pastille medium therapy with reference to " pesticide bioassay test rule NY/T1156.2-2006 ".
3, data statistic analysis: analyze with the SAS6.12 statistical software.Calculate mycelial growth inhibition rate (%) according to test data, obtain virulence regression equation formula, correlation coefficient (r), EC
50And co-toxicity coefficient.
4, evaluation method: with reference to " pesticide bioassay test rule NY/T1156.2-2006 ", according to Sun﹠amp; The co-toxicity coefficient method (CTC) of Johnson (1960) is estimated the synergistic effect of pharmacy mix, and promptly CTC≤80 are antagonism, and 80＜CTC＜120 are summation action, and CTC 〉=120 are synergistic effect.
5, result and analysis
The toxicity test that makes up apple anthrax bacteria that is mixed of Fluoxastrobin and zineb and the two different proportion thereof the results are shown in Table 1, and " phonetic: generation " is writing a Chinese character in simplified form of " Fluoxastrobin: zineb " in the table 1.
Table 1 Fluoxastrobin and zineb are mixed to the toxicity test result of apple anthrax bacteria
Indoor biometrics is the result show: Fluoxastrobin and zineb are mixed with 1: 1,1: 5,1: 10,1: 15,1: 20,1: 25,5: 1,10: 1,15: 1 and 20: 1 ratios, it shows synergistic effect to apple anthrax bacteria, and is wherein better with the synergistic effect of 1: 10,1: 15,1: 20 and 5: 1.Therefore can look 1: 10,1: 15,1: 20 and 5: 1 is the best proportioning that Fluoxastrobin and zineb are mixed.As for which kind of ratio being mixed in the production reality, still needing and take all factors into consideration decision in conjunction with synergy virulence, Financial cost, processing technology and toxicity etc.
