Abstract
The invention relates to a synergy sterilizing composition containing tetraconazole and tricyclazole. The weight ratio of tetraconazole to tricyclazole is (1-30): (1-70). The composition is mainly used for preventing and controlling rice diseases, especially rice blast and also has a good effect on preventing and controlling the diseases of other crops. The composition has he advantages of wide applicable range, good effect, low cost, low residue and obvious crop production increase effect within the recommended dose range and is safe to people, livestock, environment and the like.
Description
Technical field
What the present invention relates to is a kind of Synergistic bactericidal composition that contains tetraconazole and tricyclazole, belongs to the Pesticidal products field.
Background technology
Rice blast is claimed rice blast again, is worldwide disease, and each paddy fields of the world that extensively distributes is to endanger severe diseases in the Rice Production.In the popular time, generally can cause the paddy rice underproduction 10～20%, seriously can reach more than 40～50%.Chemical control is the main means of control rice blast; Medicament commonly used at present has rice blast, iprobenfos, kitazine etc.; But because use for many years, these medicaments all seriously produce resistance, and tricyclazole is widelyd popularize and used in recent years; But resistance has appearred in many areas; Control efficiency obviously descends, and the tricyclazole action site is single, is the protective fungicide warp; Do not have a therapeutic action, the lasting period is shorter.
Tetraconazole is the triazole bactericidal agent of developing in recent years, and the mechanism of action is sterol demethylation inhibitor, because absorption in having well, therefore can be promptly by plant absorbing, and in conducted inside; Have good protection and therapeutic activity.Lasting period is longer, generally about 6 weeks.This medicament fungicidal spectrum is wide, can be used for the control of diseases such as paddy rice, cereal crop, fruit, vegetables, horticultural crop.And under recommended dose, can promote plant growth, make it well developed root system, strengthen photosynthesis, increase the plant effective tiller, strengthen 'Gulibao ' plant growth regulator solidity and thousand kernel weight, thereby output is provided.But, use very limited because this product cost is higher.
Summary of the invention
One of the object of the invention is to overcome above-mentioned deficiency, provide a kind of applied widely, effect is good, cost is low, residual low, the Synergistic bactericidal composition that contains tetraconazole and tricyclazole with synergistic effect.
Two of the object of the invention is to provide a kind of purposes that contains the bactericidal composition of tetraconazole and tricyclazole.
The objective of the invention is to realize like this:
A kind of Synergistic bactericidal composition that contains tetraconazole and tricyclazole, said composition contains tetraconazole and tricyclazole, and the weight ratio of said tetraconazole and tricyclazole is 1 ~ 30:1 ~ 70.
The optimization weight ratio of said tetraconazole and tricyclazole is 1 ~ 25:5 ~ 50.
The weight ratio of said tetraconazole and tricyclazole is 1: 1,1: 5,1: 10,1: 15,1: 20,1: 30,5: 1,10: 1 or 20: 1.
Said combination dosage form is any one formulation that allows on the agricultural chemicals.
Said combination dosage form is wetting powder, water dispersible granules, suspending agent, aqueous emulsion or missible oil.
Said tetraconazole and the tricyclazole mass percent in composition is 1 ~ 90%.
A kind of purposes that contains the bactericidal composition of tetraconazole and tricyclazole is used for the medicine as cereal crop, melon and fruit or vegetable crop disease.
Be mainly used in the control of rice blast, especially the control of rice blast.
Compared with prior art, the invention has the beneficial effects as follows:
(1) present composition synergistic effect of in certain ratio range, doing well, the bactericidal effect of composition have had than single agent and have significantly improved;
(2) mechanism of action of two kinds of active components is different in the present composition, and the application of composition can delay or overcome the resistance of pathogen, prolongs the service life of product;
(3) present composition has enlarged fungicidal spectrum; Can be used for preventing and treating the disease of crops such as cereal crop, various melon and fruit, vegetables; Diseases such as paddy rice, watermelon, tomato, potato, apple, pears, pear tree particularly are like rice blast, wheat powdery mildew, early blight of tomato, alternaria leaf spot of apple, pear scab etc.;
(4) present composition has not only reduced use cost, has alleviated the harm to crop, environment etc. again.
Embodiment
Clearer in order to be the object of the 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 tetraconazole and tricyclazole, finds through the indoor bioassay test, and antagonistic drug venereal disease evil had obvious role in synergism after both were composite, specifically illustrated with following biologicall test instance.
The instance of measuring in kind: the composite toxicity test of tetraconazole and tricyclazole to rice blast
1, subjects: rice Pyricularia grisea
2, test method:, adopt to contain pot-culture method with reference to " pesticide bioassay test rule NY/T 1156.8-2007 ".
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/T 1156.8-2007 "; Estimate the synergistic effect of pharmacy mix according to the co-toxicity coefficient method (CTC) of Sun&Johnson (1960); Be that CTC≤80 are antagonism; 80<CTC<120 is summation action, and CTC>=120 are synergistic effect.
5, result and analysis
The toxicity test result who makes up rice Pyricularia grisea that is mixed of tetraconazole, tricyclazole and the two different proportion thereof sees table 1, and " fluorine: azoles " is writing a Chinese character in simplified form of " tetraconazole: tricyclazole " in the table 1.
Table 1 tetraconazole and tricyclazole are mixed to the toxicity test result of rice Pyricularia grisea
The indoor biometrics result of the test shows: tetraconazole and tricyclazole are mixed with 1: 1,1: 5,1: 10,1: 15,1: 20,1: 30,5: 1,10: 1,15: 1 and 20: 1 ratios rice Pyricularia grisea are shown addition or synergistic effect, and wherein the two is the most obvious with the ratio mixed synergies of 1: 5,1: 15 and 1: 20.Therefore, only from the synergy virulence relatively, can look 1: 5,1: 15 and 1: 20 is the best proportioning that tetraconazole and tricyclazole are mixed.As for which kind of ratio being mixed in the production reality, still needing combines synergy virulence, Financial cost, processing technology and toxicity etc. to take all factors into consideration decision.
