Abstract
The invention relates to a fungicide composition applied in agriculture or gardening, wherein the plant disease-controlling effect, particularly the effect of plant disease prevention and/or treatment, is greatly improved, and the invention also relates to a method for using the composition to control plant diseases. The agricultural or gardening fungicide composition is characterized in that: the composition contains dimethomorph and copper calcium sulphate, wherein the weight ratio of the dimethomorph to the copper calcium sulphate is 1:100 to 100:1. The dimethomorph and the copper calcium sulphate account for 5 to 90 percent of the weight of the fungicide composition. The agent forms of the fungicide composition are water-dispersible granules, wettable powder, coated granules, suspending agent, effervescent tablets, emulsion in water and microemulsion. The combination of the dimethomorph and the copper calcium sulphate is used for preventing or controlling plant diseases, and the plant diseases are chosen from the downy mildew and epidemic diseases of a variety of crops including melons, tomato, grape, lichee, potato and tobacco. The method for preventing or controlling the plant diseases includes the joint application of the dimethomorph and the copper calcium sulphate.
Description
Technical field
The present invention relates to the Fungicidal composition of agricultural or horticultural applications, the effect of controlling plant disease wherein especially prevents and/or treats the effect of plant disease, and remarkable improvement is arranged, and the invention still further relates to the method with said composition controlling plant disease.
Background technology
Chemical control is the important means that agricultural goes up prevention and controlling plant disease.Yet; Because the long-time agricultural chemicals that uses; A lot of plant diseases have produced resistance to common pesticides; On the other hand, the medicament of current use is still satisfied inadequately to the effect of certain plants disease, particularly to various crop downy mildew, eqpidemic diseases such as melon, the tomato that caused by oomycetes such as Peronospora, Phytophthoras, grape, lichee, potato, tobaccos.
Therefore, press for and develop new method and the medicine that is used to prevent and treat these plant diseases.In addition, current requirement on environment and economic aspect also improves constantly for agricultural chemicals, for example action spectrum, toxicity, selectivity, rate of application, residue of pesticide and favourable preparation ability etc.Therefore, exploitation is new has just become a permanent task at the for example above-mentioned novel agrochemical that has advantage with respect to existing medicine aspect certain or some at least.
Dimethomorph (dimethomorph, and chemical name (E, Z)-4-[3-(4-chlorphenyl) 3-(3, the 4-Dimethoxyphenyl) acryloyl] morpholine.Be the single-minded Oomycete fungi bactericide that kills, its effect characteristics are to destroy the formation of cell envelope, and all there is effect in each stage of oomycetes history of life, in formation stage of sporangiophore and egg spore particularly sensitivity.Be widely used in vegetables downy mildew, eqpidemic disease, seedling stage damping off, black shank etc. by the fungus-caused disease control of Mastigomycotina Oomycete, the tool systemic activity.Dimethomorph uses separately to be had than higher resistance risk, thus the composite uses of protective fungicide such as normal and mancozeb, with the generation of delaying drug resistance.The chemical structural formula of dimethomorph is following:
Copper sulphate calcium, English name copper calcium sulphate is a kind ofly known crop to be had the compound of protective effect, it can be used for resisting various bacteria and fungi, but does not have systemic action.Copper sulphate calcium is widely used in control citrus ulcer, cucumber downy mildew, downy mildew of garpe, early blight of tomato, ring rot of apple, spot defoliation, white rot, peronophythora litchi etc.Copper sulphate calcium is Bordeaux's powder of suitability for industrialized production, is protective fungicide, is sprayed at plant surface and forms layer protecting film, prevents the germ infringement, and its fungicidal spectrum is wider, can be used to prevent and treat the multiple fungi and the bacteriosis of agricultural, gardening.There is 77% wetting powder the commercially available prod.The molecular structural formula of copper sulphate calcium is: CuSO43Cu (OH) 23CaSO47H2O.
At present, also do not have any about report with dimethomorph and copper sulphate calcium Combination application.
Summary of the invention
For solving above-mentioned at least one problem or its at least one aspect; In particular for effective controlling plant disease; And/or reduce cost or application dosage; Through large number of biological test screening, the inventor finds unexpectedly and can dimethomorph and the combination of copper sulphate calcium are used for effectively preventing or the controlling plant disease, various crop downy mildew, eqpidemic diseases such as melon, the tomato that is especially caused by oomycetes such as Peronospora, Phytophthoras, grape, lichee, potato, tobacco; This effect of Combination is unexpected good, for example can delay the resistance that dimethomorph uses separately; Reduce the application dose of dimethomorph list agent greatly, thereby reduce cost; Can enlarge plant disease control spectrum; And can bring synergy or the like.
