Composition of the present invention can be by the user before use through dilution or directly use.Its preparation can be by the preparation of common processing method, is about to active substance and after liquid flux and/or solid carrier mix, and adds in surfactant such as emulsifier, dispersant, stabilizing agent, wetting agent, adhesive, the defoamer etc. one or more again.
Bactericidal composition of the present invention can be processed into acceptable forms on any agricultural on demand.For example can be suspending agent, aqueous emulsion, wetting powder, colloidal suspending agent, (aqueous dispersion) granula.Wherein preferred dosage form is suspending agent, wetting powder, (aqueous dispersion) granula.The compound method of several formulations of bactericidal composition of the present invention is exemplified below:
The preparation of suspending agent: active component content is 5%～35% in the common prescription.With water is medium, and former medicine, dispersant, suspending agent and antifreeze etc. are added in the sand mill, grinds, and makes suspending agent.
The preparation of aqueous emulsion: former medicine, solvent added with emulsifier be in the same place, make and be dissolved into even oil phase.Water, antifreeze etc. is mixed, becomes the homogeneous water.Under high-speed stirred, water is joined oil phase or oil phase is joined water, form the aqueous emulsion of favorable dispersibility.Aqueous emulsion active component content of the present invention is generally 5%-15%.Be the preparation emulsifiable concentrate, compound of the present invention is dissolvable in water a kind of or several mixed solvents, adds emulsifier again and strengthens the dispersion effect of compound in water.
The preparation of wetting powder: by the prescription requirement, former medicine, various surfactant and solid diluent etc. are fully mixed, after ultrafine crusher is pulverized, promptly obtain the wetting powder product of predetermined content (for example 10%-40%).For preparation is suitable for spraying the wetting powder of usefulness, compound of the present invention can with pressed powder such as clay, inorganic silicate, carbonate and wetting agent, adhesive and/or the dispersant composition mixture of porphyrize.
The preparation of water-dispersible granules: former medicine and powdery solid thinner, wetting spreader-sticker and adhesive etc. are mixed pulverizing; after adding the water kneading again; add in the comminutor that the certain specification screen cloth is housed and carry out granulation, and then drying, screening (pressing the screen cloth scope).Also former medicine, dispersant, disintegrant and wetting agent and solid diluent can be added in the sand mill, be medium milling with water, makes suspending agent, carries out spray drying granulation then, and formulation content is 20%～30% granular product usually.
Composition of the present invention also can contain other component, for example other compound with weeding, desinsection or bactericidal property protective fungicide particularly.Also can mix, can produce additional advantage and effect thus with nematocide, protective agent, growth regulator, nutrient for plants or soil conditioner.
The present invention is interested especially to be the duration of improving the protection activity of The compounds of this invention.Use a kind of carrier that can shift to the also slow release Fungicidal compounds of being protected of plant, the preparation of this slow release can be put near the soil the trailing plant root; Or comprise a kind of adhesion component, so that can be applied directly on the stem of trailing plant.
Composition of the present invention can be used by common method, as cast, injection, spraying, dusting, scatter or be fuming.Amount of application of the present invention is with weather condition or crop state variation.Time of application can be before or after infecting.This point is very important, because in fact the infection of Fa Shenging can not be realized immediately.The duration of protection is relevant with selected individualized compound, also relevant with many extraneous factors usually, and for example weather can slow down climatic influences usually by using suitable formulation.
Microbicide compositions of the present invention has protection concurrently; treat and root out activity; can be used for for example cucumber of many kinds of crops; wheat; tomato; corn; peanut; paddy rice; grape; capsicum; pimento; eggplant; tomato; lettuce; Chinese cabbage; strawberry; custard squash; and flowers; traditional Chinese medicine and lawn, control is by Oomycete; Phycomycetes; Ascomycetes and microbial plant disease of deuteromycetes cause of disease such as powdery mildew; downy mildew; early blight; late blight; scab; rust; glume blight; verticillium wilt; leaf mold; brown spot; anthracnose; net blotch; leaf spot; damping off; rice blast; gray mold; the frost eqpidemic disease; rotten mildew; damping off; black stem; canker; white blister; (millet) poliosis etc.
The invention allows for the application of bactericidal composition of above-mentioned meaning and the method for catching and killing fungi at the scene, comprise with said composition and handle this place that it can be the plant that for example is subjected to fungal attack, the seed of this plant or the medium of this plant growing.
Therefore, composition of the present invention has following three advantages: the one, and said composition shows significant synergistic effect in certain ratio range, both improved protection effect, has reduced the mu use cost, has enlarged fungicidal spectrum again.The 2nd, because the mechanism of action difference of each single agent in the said composition, the problem that does not have cross resistance is so the application of said composition can reach and delay drug-fast generation of pathogen and development, help to prolong the result of use of this medicament, reduce the purpose that pesticide resistance produces probability.The 3rd, improved safety, being mixed will be lower to the influence of environment, safer.
