Description
Technical field
The present invention relates to a kind of bactericidal composition, especially a kind of binary built bactericidal composition that contains tetraconazole.
Background technology
Tetraconazole (tetraconazole) has another name called fluorine ether azoles, is triazole bactericidal agent, is sterol demethylation inhibitor, inhales conduction in having, and good protection and therapeutic activity are arranged.This medicament all has application on cereal crop, fruit tree, vegetables and ornamental plants, can prevent and treat wheat powdery mildew, loose smut of wheat, wheat rust, the bunt of wheat, wheat glume blight, barley leaf blotch, loose smut of barley, barley banded sclerotial blight, maize head smut, head smut of sorghum, melon and fruit powdery mildew, sigatoka, alternaria leaf spot of apple, pear scab and grape powdery mildew etc.
In the real process of agricultural production, preventing and treating the most incidental problem of disease is the drug-fast generation of germ.The agent of chronic administration agricultural chemicals list lures that easily disease produces serious resistance into.Carrying out compositely through tetraconazole and other active ingredient, is to avoid one of effective way that the resistance germ produces.Composite between the different active ingredients, according to the effect of practical application, judge that composite is synergy or antagonism.The prescription that compound synergic is good can significantly improve actual control efficiency, reduces the usage amount and the access times of agricultural chemicals, thereby delays the generation speed of germ resistance.
In view of this, develop the synergistic composition that contains tetraconazole and have important application value.
Summary of the invention
The bactericidal composition that the purpose of this invention is to provide a kind of efficient, safety, environmental protection is to satisfy the needs of agricultural production, and composition has synergistic effect, can improve preventive effect and is of value to and delays the drug-fast generation of germ.
In order to address the above problem; The inventor has carried out a large amount of tests; It is unexpected that tetraconazole and the phonetic phenol of second found be mixed in the certain proportion scope, has obvious synergistic effect, and the control efficiency that can obviously improve corps diseases also can delay the drug-fast generation of germ.
The phonetic phenol of said second is a kind of miazines bactericide, can absorb through blade and root.Because its action site is different fully with other series bactericidal agents, thus for to the germ of benzimidazole and triazole bactericidal agent generation resistance, prevention and result of treatment that the phonetic phenol of second is all done well.Be mainly used in the control crop powdery mildew at present.
Technical scheme of the present invention is following:
A kind of bactericidal composition that contains tetraconazole; The active component that it is characterized in that composition is tetraconazole and the phonetic phenol of second; The weight ratio of tetraconazole and the phonetic phenol of second is 80: 1～1: 80; Two kinds of active component gross weight percentage compositions are 1～80% in the composition, and all the other are to allow in the agricultural chemicals to use and the acceptable auxiliary element.
As a kind of improvement of the present invention, in the composition the phonetic phenol of active component tetraconazole and second preferably weight ratio be 20: 1～1: 20, two kinds of active component gross weight percentage compositions are 1～50% in the composition.
Composition pesticide of the present invention can be prepared into known method and be fit to any one formulation that agricultural is used, and reasonable formulation is wetting powder, suspending agent, water dispersible granules, missible oil.
The auxiliary agent that uses in the composition of the present invention comprises that solvent, dispersant, emulsifier, stabilizing agent, antifreezing agent, thickener etc. and other are of value to the known substance that active component is stablized and drug effect is brought into play in preparation; All be the various compositions of using or allow use in the pesticidal preparations always; Do not have special qualification, concrete composition and consumption require to confirm through simple experiment according to prescription.
Bactericidal composition of the present invention can be prevented and treated the plurality of plant diseases that is caused by disease funguses such as sac fungi, basidiomycetes, imperfect funguss; Be applicable to control cereal class, various melon and fruit and vegetable disease; Particularly prevent and treat crop pests such as paddy rice, wheat, capsicum, apple, banana, mango, cucumber, tomato, embroider disease, cladosporium leaf and fruit mould of tomato, mango anthracnose, powdery mildew of cucumber, banana freckle, citrus scab, leaf spot of peanut etc. like wheat powdery mildew, apple.
Compared with prior art, beneficial effect of the present invention is:
1, synergistic effect is remarkable.Composition is compared bactericidal effect with single agent and is obviously improved owing to increased the action site to the target fungi,
2, after drug effect improved, the amount of application of active ingredient and the minimizing of medication number of times had reduced drug cost, had reduced residue of pesticide and to the pollution of environment.
3, help resistance management.The mechanism of action of two active ingredients is different fully in the composition, has reduced the single selection pressure to germ, does not have mutual pesticide resistance, therefore can avoid and delay the drug-fast generation of germ.
