Abstract
The invention relates to a sterilization composition containing fluazinam and sulphur and application thereof. The composition contains fluazinam and sulphur, wherein the weight ratio between the fluazinam and the sulphur is 1-40: 1-60. The composition can be applied to disease control of cereal crops, melons or vegetables. The composition is wide in application scope, good in effect, low in cost, small in residue and safe for human, livestock, the environment and the like.
Description
(1) technical field
The present invention relates to a kind of bactericidal composition and uses thereof, relate in particular to a kind of bactericidal composition that contains fluazinam and sulphur, be mainly used in the control of cereal crop disease.
(2) background technology
Fluazinam (Fluazinam) is the phenyl amines wide-spectrum bactericide, and its mechanism of action is that mitochondrial oxidation phosphorus is extremely dissolved coupling agent, by the inhibition spore, gives sprouting, mycelia breakthrough, growth and sporulation and suppresses infecting of pathogen.The fluazinam applicable crops is wide in grape, apple, pears, oranges and tangerines, wheat, soybean, potato, tomato, cucumber, paddy rice, tea, lawn etc., to interlink spore genus, Botrytis, Phytophthora, Plasmopara, Sclerotinia and Venturia bacterium are very effective, as gray mold of cucumber, rot, downy mildew, anthracnose, powdery mildew, stem's pestilence of rotting, tomato late blight, apple scab, leaf spot, Pear black spot, rust, paddy rice slightly pain is sick, banded sclerotial blight, the oat hat lures disease, grape grey mould, downy mildew, citrus scab, gray mold, potato late blight, the lawn spot disease.Botrytis cinerea to anti-benzimidazole type and dicarboximide class biocide agent also has good result.Resistance of rainwater washing against, the lasting period is long.Except bactericidal activity, fluazinam also has certain acaricidal activity, engraves mite, kamisawa tetranychus etc. as citrus red mite, China pink.
Though fluazinam has above-mentioned advantage, because cost is higher, application is very limited at home at present.
The sulphur application is very extensive, in agricultural production, also can be used for the control of corps diseases, its mechanism of action is respiration inhibitor, acts on electron transfer process between germ helium reduction system cytochrome b and c, capture electronics, disturb normal " oxidation-reduction ".Have protection and therapeutic action, but there is no systemic activity.Can be used for wheat, beet, vegetables such as cucumber, eggplant etc., fruit tree such as apple, Lee, peach, grape, oranges and tangerines, the control of the crop pests such as matrimony vine.Controlling object is for preventing and treating wheat powdery mildew, rust, smut, head blight, cucurbits powdery mildew, and apple is bright, pears, peach scab, grape powdery mildew etc., except having bactericidal activity, sulphur also has acaricidal action, as be used to preventing and treating phyllocoptruta oleivora etc.
Absorption protective fungicide in the sulphur right and wrong, do not have result for the treatment of, not absorption in tool.
(3) summary of the invention
One of purpose of the present invention is to overcome above-mentioned deficiency, and a kind of applied widely, effective, cost is low, the lasting period is long bactericidal composition that contains fluazinam and sulphur is provided.
Two of purpose of the present invention is to provide a kind of purposes that contains the bactericidal composition of fluazinam and sulphur.
The object of the present invention is achieved like this:
A kind of bactericidal composition that contains fluazinam and sulphur, described composition contains fluazinam and sulphur, and the weight ratio of described fluazinam and sulphur is 1～40: 1～60.
The preferred weight ratio of described fluazinam and sulphur is 5～30: 10～45.
Described combination dosage form is any one formulation allowed on agricultural chemicals.Such as wetting powder, water dispersible granules, suspending agent, aqueous emulsion, missible oil or seed coat agent etc.
Described fluazinam and the sulphur mass percent in above-mentioned formulation is 5～90%.
A kind of purposes that contains the bactericidal composition of fluazinam and sulphur, for the control as the cereal crop disease.
The present composition can be used for rice sheath blight disease, rice blast, false smut, paddy rice sheath maize ear rot, paddy rice glume blight, wheat powdery mildew, wheat rust, wheat scab, take-all, the corn northern leaf blight, maize head smut, the corn loose kernel smut, corn smut, barley leaf blotch, net blotch of barley, leaf rust of barley, the triticale rust, the Chinese sorghum stripe disease, the Chinese sorghum spot disease, Chinese sorghum smut, the millet downy mildew, millet blast, rice sheath blight disease, oat sheath maize ear rot, the Oat Red leaf disease, the Grain Production of Amaranthus fusarium wilt, Grain Production of Amaranthus anthracnose, broomcorn millet is checked the control of the cereal crop diseases such as head smut.Be preferred for the control of rice blast, net blotch of barley, jowar smut, wheat scab, corn smut.
Compared with prior art, the invention has the beneficial effects as follows:
(1) present composition synergistic effect of doing well in certain ratio range, the bactericidal effect of composition has had and has significantly improved than single dose, has reduced simultaneously agricultural chemicals using dosage and cost, has reduced residually, has also alleviated the harmful effect to environment;
(2) the mechanism of action difference of two kinds of active components in the present invention, the application of composition can delay or overcome the resistance of pathogen, extends the service life of product;
(3) present composition is good to the cereal crop diseases control, in addition, also can be used for the control of its corps diseases.
