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 the mitochondria phosphorous oxide is extremely dissolved coupling agent, gives sprouting, mycelia breakthrough, growth and sporulation through the inhibition spore 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., and is very effective to interlink spore genus, Botrytis, Phytophthora, Plasmopara, Sclerotinia and Venturia bacterium, like gray mold of cucumber, rot, downy mildew, anthracnose, powdery mildew, the rotten pestilence of stem; Tomato late blight, apple scab, leaf spot, pears black spot, rust; Paddy rice is sick, the banded sclerotial blight of pain slightly; 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. like citrus red mite, China pink.
Though fluazinam has above-mentioned advantage,, use very limited at present at home because cost is higher.
The sulphur application very extensively; 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 the c; Capture electronics, disturb normal " OR ".Have protection and therapeutic action, but do not have 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 crop pests such as matrimony vine.Controlling object is used to prevent and treat 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 is used to prevent and treat phyllocoptruta oleivora etc.
Absorption protective fungicide in the sulphur right and wrong, readily good therapeutic effect, not absorption in the tool.
(3) summary of the invention
One of the object of the 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 the object of the invention is to provide a kind of purposes that contains the bactericidal composition of fluazinam and sulphur.
The objective of the invention is to realize like this:
A kind of bactericidal composition that contains fluazinam and sulphur, said composition contains fluazinam and sulphur, and the weight ratio of said fluazinam and sulphur is 1～40: 1～60.
The preferred weight ratio of said fluazinam and sulphur is 5～30: 10～45.
Said combination dosage form is any one formulation that allows on the agricultural chemicals.For example wetting powder, water dispersible granules, suspending agent, aqueous emulsion, missible oil or the agent of kind clothing etc.
Said 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 is used for the control as the cereal crop disease.
The present composition can be used for rice sheath blight disease, rice blast, false smut, rotten sick, the paddy rice glume blight of paddy rice sheath; Wheat powdery mildew, wheat rust, wheat scab, take-all, the corn northern leaf blight, maize head smut, corn loose kernel smut, corn smut, barley leaf blotch, net blotch of barley, leaf rust of barley; The triticale rust; Chinese sorghum stripe disease, Chinese sorghum spot disease, Chinese sorghum smut, the millet downy mildew, millet blast, rice sheath blight disease, rotten sick, the oat red-leaf disease of oat sheath; Grain Production of Amaranthus fusarium wilt, Grain Production of Amaranthus anthracnose, broomcorn millet is checked the control of 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 in certain ratio range, doing well, the bactericidal effect of composition have had than single agent and have significantly improved, and have reduced agricultural chemicals using dosage and cost simultaneously, have reduced residually, have also alleviated the harmful effect to environment;
(2) mechanism of action of two kinds of active components is different among the present invention, and the application of composition can delay or overcome the resistance of pathogen, prolongs 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.
