Abstract
The invention relates to a compound drug for preventing and treating powdery mildew of Radix Astragali, which belongs to the technical fields of plant protection and pesticides. The compound drug is characterized by comprising the following effective components: 15 to 20% of sulphur and 5 to 10% of triadimefon, more preferably, 15 to 20% of sulphur and 8 to 10% of triadimefon. A preparation method for the compound drug comprises the following steps: adding sulphur in alcohol; then adding triadimefon powder, phenethyl phenol polyoxyethylene ether, glycol and water; and carrying out uniform mixing in the reaction vessel under stirring to prepare missible oil. The compound drug can reduce prevention and treatment frequency, improve prevention and treatment efficiency, decrease environmental pollution and enhance product safety.
Description
Technical field
The present invention relates to plant protection and technical field of pesticide, specifically a kind of compound drug preventing and treating Radix Astragali powdery mildew.
Background technology
At the beginning of the Radix Astragali powdery mildew during morbidity leaf just, the back of the body two look unfamiliar white powder mildew, petiole, stem catch an illness also raw white mildew or mildew, and time serious, completeblade is covered by white lead, cause that blade is withered or Herb is withered.Pathogenic bacteria survives the winter on sick leaf with cleistothecium, and the next spring produces ascospore and carries out its spread in china；The mycelia survived the winter on this external bud, next year also can fall ill.
Because Radix Astragali controlling powdery mildew is more difficult, preventing and treating and use substantial amounts of pesticide in process, not only make pathogen create Drug resistance, and the persticide residue of the Radix Astragali increases, the quality of the Radix Astragali is greatly lowered.
Triazolone belongs to hypotoxicity antibacterial.Former medicine rat acute LD50 of passing through mouth is 1000-1500 mg/kg, rat percutaneous LD50 > 1000 mg/kg, be a kind of efficiently, low toxicity, low-residual, lasting period length, triazole bactericidal agent that interior absorption is strong.After being absorbed by each several part of plant, can conduct in plant.Rust and powdery mildew had prevention, root out, the effect such as treatment.
Sulfur has parasite killing, kills demodicid mite and bactericidal action.The fungal spore of Erysiphaceae is had selection toxicity by it, is therefore used as the protective fungicide of this section's disease for many years.Demodicid mite class is also had selection toxicity by sulfur, so being also commonly used for killing demodicid mite.
Summary of the invention
It is an object of the invention to provide a kind of compound drug preventing and treating Radix Astragali powdery mildew, solve the blindness use situation to chemical pesticide.
For solving the problems referred to above, concrete scheme is proposed:
A kind of Recompounded pesticide, its effective ingredient is, sulfur 15%-20%, triazolone 5%-10%；
Its preferred version is: sulfur 15%-20%, triazolone 8%-10%；
Described triazolone sulfur compounded pesticide: sulfur 18%, triazolone 10%；
Described triazolone sulfur compounded pesticide: sulfur 20%, triazolone 8%；
Triazolone chemical formula is 1 one (4 monochloro-benzene oxygen base) one 3,3 one dimethyl 1 (1H-1,2,4 one triazole-l-base)-α-butanone, for known substance；Sulfur is known substance.
Recompounded pesticide preparation method of the present invention, weighs each former medicine in the desired amount, adds sulfur in ethanol to dissolve and adds triazolone powder, phenethyl phenol polyethenoxy ether, ethylene glycol and water, after stirring, makes cream in reactor.
The beneficial effects of the present invention is:
1, it is a kind of Recompounded pesticide, has obvious potentiation, use this medicine can reduce preventing and treating number of times, improve control rate.
2, water of the present invention makees solvent, replaces the organic solvents such as benzene, decreases environmental pollution, improve the safety of product.
Detailed description of the invention
Below the implementation of the present invention being described in detail, this example is carried out under premised on technical solution of the present invention, gives detailed embodiment and concrete operating process.
Formula one: sulfur 18%, triazolone 10%；
Formula two: sulfur 20%, triazolone 8%；
Formula three: sulfur 15%, triazolone 8%；
Formula four: sulfur 15%, triazolone 10%；
Formula five: sulfur 18%, triazolone 8%.
Preparation method, weighs each former medicine in the desired amount, adds phenethyl phenol polyethenoxy ether, anti-ethylene glycol and water, after stirring, makes cream in reactor.
Test one, the Chemicals of above-mentioned Recompounded pesticide
(1) Recompounded pesticide formula one, formula two, formula three, formula four, formula five, triazolone are taken
(2) preparation of Powdery Mildew
Purify Powdery Mildew with tissue isolation separation, make 5 × 106Individual/ml spore suspension.
(3) screening pesticide control
Take the Radix Astragali blade of the consistent healthy growth of upgrowth situation, it is cut into the rectangle of 60mm × 40mm, then Recompounded pesticide formula one, formula two, formula three, formula four, formula five, triazolone it are immersed in, contrast with clear water, take out after 10min, the spore suspension that will prepare, is uniformly sprayed on the positive and negative of blade, and 3 repetitions are done in each process；When the lesion area that clear water processes reaches more than 90%, measure lesion area with scab analyzer.
(4) the drug effect significance of difference compares
Calculate prevention effect: prevention effect=(the average lesion area that the average lesion area of 1-chemicals treatment/clear water processes) × 100；The significance of difference with the more each medicament of spss method.
Result shows:
Test two: the above-mentioned Recompounded pesticide field efficacy to Radix Astragali powdery mildew
(1) medicament kind
Formula one (sulfur 18% triazolone 10%), formula two (sulfur 20% triazolone 8%), formula three (sulfur 15% triazolone 8%), formula four (sulfur 15% triazolone 10), formula five (sulfur 18% triazolone 8%)；
(2) process
In Radix Astragali powdery mildew generation in August field test in serious period, every kind of medicament sprays 18ml every mu, and three repetitions are done in every kind of test, do contrast test with clear water, and August 1 sprayed once, and August 11 sprayed once again, and a situation arises to observe powdery mildew August 20.
(3) result and analysis
Adopt 5 point samplings, collecting sample, viewing test result, as shown in the table:
Result represents: with the Recompounded pesticide of sulfur 18% triazolone 10% and sulfur 20% triazolone 8%, prevention effect reaches 86.67% and 86.01%, and its prevention effect is best.
