Abstract

The present invention discloses one kind of germicide composition containing propamidine and thiophanate-methyl and its application. The composition contains propamidine and thiophanate-methyl in the weight ratio of 5-30 to 1-60. The composition may be used in preventing and controlling diseases of grain crop, melons, fruits and vegetable, and has wide application range, low cost and high plant disease preventing and controlling effect.

Description

A kind of bactericidal composition and application thereof that contains propamidine and thiophanate-methyl
Technical field
The present invention relates to a kind of bactericidal composition and uses thereof, especially a kind of is the bactericidal composition and the application thereof of main active with propamidine and thiophanate-methyl.
Technical background
Propamidine (propamidine) is a wide-spectrum bactericide, has protection and therapeutic action.The result shows through field control effectiveness test, and the gray mold of tomato, cucumber is had preventive effect preferably.Spraying times is decided on the state of an illness, and general 7 days spray medicines at interval once.This product is being prevented and treated aspect the lasting period of disease shortlyer, causes the medication number of repetition more.And do not see to have on corps diseases such as wheat powdery mildew etc. and use.
Thiophanate-methyl (thiophanate-methyl) is a kind of efficient, low toxicity sterilization punishment, and tool prevention and systemic action are because of medicament can change into carbendazim after entering in the plant corpus, so also belong to benzimidazole.Can be widely used in multiple diseases such as grain, cotton, oil, vegetables, fruit tree.Can prevent and treat gibberella zeaze petch of wheat and barley, stinking smut, wheat powdery mildew, leaf blast disease, the rice sheath blight, sclerotinia rot of colza etc.Can be used for sweet potato black rot, the big leaf spot of corn, rice purple stalk disease, head smut of sorghum in addition.Thiophanate-methyl for a long time, repeatedly uses on Crop in China, and this makes the target germ strengthen gradually its resistance, and the cost that makes thiophanate-methyl prevent and treat disease increases and drug effect reduces greatly.
Summary of the invention
The objective of the invention is at above-mentioned technical problem provide a kind of applied widely, cost is low, the effective plant sterilization composition that contains propiconazole and thiophanate-methyl.
A further object of the invention provides the purposes of this bactericidal composition.
The objective of the invention is to realize by following measures:
A kind of bactericidal composition is characterized in that containing propamidine and thiophanate-methyl, and wherein the weight ratio of propamidine and thiophanate-methyl is: 5~30: 1~60.
Described bactericidal composition, wherein the weight ratio of propamidine and thiophanate-methyl is 5~20: 10~50.
Described bactericidal composition, wherein propamidine and thiophanate-methyl and known auxiliary agent and excipient are re-dubbed any one formulation that allows on the agricultural chemicals.These known auxiliary agents, excipients have dispersant, diffusant, defoamer, wetting agent, disintegrant etc.
Described bactericidal composition is characterized in that its formulation is pulvis, wetting powder, suspension emulsion, missible oil or granule.
The application of described bactericidal composition aspect control cereal class, melon and fruit or vegetable crop damage by disease and insect.
Beneficial effect of the present invention:
1, the used propamidine of the present invention is an acid amide fungicides, and thiophanate-methyl is an azoles fungicide, and both are mixed mutually and can produce conflict, but Synergistic reduces dosage, reduces cost.
2, the present composition scope of application increases, be applicable to crop pests such as control cereal class, vegetables, banana, capsicum, paddy rice, mango, pineapple, as wheat powdery mildew, pepper anthracnose, balsam pear scab, scutellum rot of orange, powdery mildew of cucumber, early blight of tomato and late blight.
