Abstract
The invention relates to hexaconazole and methyl composition bactericide, belonging to a spot defoliation prevention and treatment medicament of vegetable and fruit plants. In the practical process of agricultural production, the best prevention and treatment effect can not be achieved by singly using one medicament and one of the most economical and effective method for overcoming the defect is to mix the effective ingredients of different breeds. By using the hexaconazole and methyl based on the weight ratio of 1:2-5 in addition with a proper amount of auxiliaries to prepare the bactericide, the invention improves the medicament synergistic effect and the prevention and treatment effect. The invention has the advantages of good integrated prevention and treatment effect, little drug consumption, high overall benefit of products, and the like.
Description
Technical field
The composition pesticide that this invention relates to is to be that active ingredient is prepared through special ratios with the pure and mild kresoxim-methyl of own azoles, in order to the control alternaria leaf spot of apple, belongs to the pesticide chemical technical field.
Background technology
Own azoles alcohol: belong to azoles fungicide, sterol demethylation inhibitor, the disease that fungi especially Basidiomycota and Ascomycota are caused has the protection and the therapeutic action of broad spectrum activity.Destroy and stop the biosynthesis of the cell membrane important composition composition ergosterol of germ, cause cell membrane not form, make germ death.Have interior suction, protection and therapeutic activity.
Kresoxim-methyl: be a kind of efficient, wide spectrum, new type bactericide.The bactericidal activity that not only has wide spectrum is simultaneously with excellent protection and therapeutic action.There is not cross resistance with other bactericide commonly used, and longer than the conventional sterilization agent lasting period.Have the selectivity of height, to crop, people and animals and beneficial organism safety, pollution-free substantially to environment.
In growing process, a kind of plant disease is often by due to several germs, and list can not be obtained the best with a kind of effect of chemical control, and is easy to generate resistance problem again.It is composite that one of most economical effective method that overcomes is that the active ingredient of different kind is carried out, according to the actual tests effect judge certain composite be synergy, add and, or antagonism.Filter out and have the good prescription of synergistic effect,, reduced dosage, thereby reduced the agricultural chemicals use cost, delayed the generation of disease drug resistance simultaneously greatly, improved product economy and social benefit owing to obviously improved integrated control effect.
Summary of the invention
For the control alternaria leaf spot of apple, the invention provides a kind of own azoles alcohol, kresoxim-methyl composition fungicide.
To achieve these goals, component of the present invention is own azoles alcohol, kresoxim-methyl, N, compositions such as dinethylformamide, Tween 80, pure water.The pure and mild kresoxim-methyl weight ratio of the own azoles of solid is 1: 2～5 in its preferred forms, and kresoxim-methyl and own azoles alcohol accumulating weight is 15%～80% in the combination agent.Its technology is for will fully mixing under own azoles alcohol, the kresoxim-methyl composition normal temperature.
It is remarkable that the present invention has synergy, and integrated control effect is good, and dosage is little, low cost and other advantages.
Embodiment
Use N, dinethylformamide and Tween 80 with kresoxim-methyl and former medicine dissolving of own azoles alcohol and emulsification, add an amount of pure water again and are made into mother liquor respectively.Proportioning pure according to own azoles and that the kresoxim-methyl weight ratio was respectively 1: 1.5,1: 2,1: 2.5 is moved with mother liquor and is disposed 3 groups altogether, every group of soup that is formulated as 5-7 variable concentrations again.Get respectively 2 milliliters of above-mentioned soups, move into respectively in the culture dish of 9 centimetres of diameters, the PSA medium of adding thawing respectively in each ware is each 10 milliliters again, contrasts with clear water and the water treatment of adding tween.Each concentration of each proportioning is handled each ware, repeats 4 times.Soup and medium is full and uniform, after treating that medium solidifies fully, insert in every ware central authorities and to cultivate good in advance and respectively one of alternaria leaf spot of apple bacterium bacterium cake (5 millimeters of diameters), put then in the PYX-250Q-A climatic cabinate, cultivated 6 days down at 26 ℃, intersect and measure each bacterium colony of handling expansion diameter.Calculate preventive effect, obtain EC
50, EC
90, virulence regression equation, correlation coefficient and co-toxicity coefficient, judge the co-toxicity effect of kresoxim-methyl and own azoles alcohol with the co-toxicity coefficient value to alternaria leaf spot of apple, the co-toxicity coefficient value is a summation action about 100, and being significantly less than at 100 o'clock is antagonism, is synergistic effect greater than 100 o'clock obviously.
Own azoles alcohol, kresoxim-methyl are to the indoor formulation screening test result of alternaria leaf spot of apple
Application example one: alternaria leaf spot of apple
By own azoles alcohol 10%, kresoxim-methyl 20% adds an amount of auxiliary agent and filler, makes 30% suspending agent.Press 7.5mg/Kg concentration and handle alternaria leaf spot of apple, control efficiency is 96.4%.Contrast medicine kresoxim-methyl and own azoles alcohol use after the same method, and preventive effect is respectively 95.6% and 92.6%.
Application example two: alternaria leaf spot of apple
By own azoles alcohol 10%, kresoxim-methyl 25% adds an amount of auxiliary agent and filler, makes 35% suspending agent.Press 7.5mg/Kg concentration and handle alternaria leaf spot of apple, control efficiency is 98.1%.Contrast medicine kresoxim-methyl and own azoles alcohol use after the same method, and preventive effect is respectively 95.6% and 92.6%.
Claims (2)
1. the pure and mild kresoxim-methyl composition fungicide of own azoles it is characterized in that described bactericide is the pure and mild kresoxim-methyl composition of the own azoles of solid, and the combination weight ratio is 1: 2～5.
2. the pure and mild kresoxim-methyl composition fungicide of the own azoles described in the claim 1, its feature are that also the quality percentage composition of the pure and mild kresoxim-methyl accumulation of own azoles in the combination agent is at 15%-80%.
