Abstract

The present invention discloses one kind of germicide composition containing pyraclostrobin and chlorothalonil and its application. The composition contains pyraclostrobin and chlorothalonil in the weight ratio of 1-30 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 pyraclostrobin and tpn
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 pyraclostrobin and tpn.
Technical background
Pyraclostrobin (pyraclostrobin) is a kind of broad-spectrum high efficacy bactericide, and the multiple diseases that can prevent and treat cereal, citrus, paddy rice, banana, cucurbit, grape, peanut, potato, beet, tomato and turf is is especially prevented and treated soybean rust.But domestic now do not have a former medicine manufacturing enterprise, and its product mainly is by abroad providing, and product price is higher, and the peasant is difficult to receive, and is relatively poor in the ability that Chinese large tracts of land is promoted.
Tpn (Chlorothalonil) is a kind of broad spectrum activity protective fungicide punishment, and the various crop fungal disease is had prevention effect.Efficacy stability, the longevity of residure is long.Can be used for crops such as wheat class, paddy rice, vegetables, fruit tree, peanut, tealeaves.Tpn is domestic bactericide relatively more commonly used, and the time of especially using on crops is long, and this some bacterium that makes has produced certain resistance to tpn, and prevention and control capability is descended.
Summary of the invention
The objective of the invention is provides a kind of applied widely, plant sterilization composition that contains pyraclostrobin and tpn that cost is low, effective at above-mentioned technical problem.
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, it contains pyraclostrobin and tpn, and wherein the weight ratio of pyraclostrobin and tpn is 1~30: 1~60.
Described bactericidal composition, wherein the weight ratio of pyraclostrobin and tpn is 5~25: 5~50.
Described bactericidal composition, wherein pyraclostrobin and tpn 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, its formulation are pulvis, wetting powder, suspension emulsion, emulsifiable concentrate or granule.
The application of described bactericidal composition aspect control cereal class, melon and fruit or vegetable crop disease.
Beneficial effect of the present invention:
1, the used pyraclostrobin of the present invention is an acid amide fungicides, and tpn 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 the crop pest of control cereal class, various melon and fruit, vegetables, particularly prevent and treat crop pests such as paddy rice, wheat, capsicum, banana, mango, pineapple, cucumber, tomato, tobacco, as wheat powdery mildew, sclerotinia rot of colza, pepper anthracnose, balsam pear scab, scutellum rot of orange, powdery mildew of cucumber, early blight of tomato and late blight.

Application Example:
Prevent and treat the early blight of tomato test with the preparation that the foregoing description makes.Experimental condition and the results are shown in following table:
1, test is handled: this test medicine consumption is established three concentration of treatment respectively according to the difference of each composition, and the contrast medicament is respectively commercially available agricultural chemicals 75% tpn wetting powder and 25% pyraclostrobin aqueous suspension agent and the test of blank clear water.
2, the test method test and Selection is carried out in the more serious plot of early blight of tomato over the years, repeats 4 times; Inspection drug effect method before the dispenser after investigation and the control is: investigate whole blades from top to bottom.Check the early blight occurrence degree.
3, result of the test sees the following form:
