Description
Technical field
The present invention relates to the pharmaceutical composition and preparation of a kind of compounding, and in particular to a kind of pyraclostrobin-containing and 6- benzyl ammonia
The composition of base purine and dispersible oil-suspending agent.Belong to agricultural chemicals technical field.
Background technology
Canker of apple fruit, is commonly called as bark rot, and smelly skin disease, is the important disease of north of China apple tree.The sick main harm 6 years
The bearing-age tree of the raw above, causes that tree vigo(u)r is weak, limb is withered, dead tree, or even ruins garden.North China, northeast, the Northwest's generation are general
Time.Valsa mali is weak parasite, every to can result in the factor that tree vigo(u)r dies down and induce canker of apple fruit.This disease one
There are two extension peak periods year.That is 3~April and 8~September, spring overweight autumn.When tree vigo(u)r is healthy and strong, nutritional condition is good, morbidity
Slightly.When tree vigo(u)r is weak, fertilizer deficiency arid, as a result excessively, after freeze injury and the big generation of red spider, the big generation of rot causes fruit
Moisture is reduced.
The type of disease 3 that canker of apple fruit has ulcer, branch withered and surface is burst.Ulcer type occurs on early spring trunk, branch bark
Bronzing, water stain shape, micro- protuberance, circle to Long Circle scab.Quality is soft, easily tear, hand pressure depression, flows out yellowish-brown juice,
There is vinasse taste.There is crack at drying shrinkage afterwards, edge, and sick skin grows pore.Pore sprays golden yellow tendril thing when moist.Branch
There is scab on 2~5 years spring raw branch in withered type, and blur margin is clear, does not swell, and not in water stain shape, rear dehydration is dried up, and close life is small
Black grain point.Superficial ulcer type occurs slightly with bronzing, the aphtha spot for slightly moistening on summer and autumn rhytidome.Edge is irregular, and one
As 2~3 centimetres it is deep, thumbnail to tens centimetres, rot.Drying shrinkage is in pie afterwards.Ulceration is formed after late fall.
The preventing and treating of current apple branch valsa canker it is main using scrape control and coating by the way of, scrape and thoroughly scraped when controlling most sick portion's group
(carry disease germs xylem) is knitted, 0.5~1 centimetre of good skin is scraped off around it, scab spreads to fusiformis, and shaving is smooth.Exist immediately after scraping
Sick portion's coating, coating exceeds 5~8 centimetres outside sick scar, applies 1 medicine after one month again.Sick skin is packed up in time, is taken orchard out of and is burnt.
Trunk whitewashing.With early spring trunk whitewashing before winter, there is the reduction bark temperature difference, reduce the effect that freeze injury and day burn, to preventing and treating limb corruption
Rotten disease has certain effect.When due to consistent for many years, waste time and energy, germ resistance to the action of a drug enhancing, prevention effect is poor, high recurrence rate.

Above-mentioned pyraclostrobin -6-benzyl aminopurine dispersibles the application method of oil-suspending agent, 10 before spring rudiment~
20 days, if being scraped the shallow wound in arterial highway in length and breadth to scab, 50~100 times of oil-suspending agent dilute with water then is dispersibled by described,
Branches of fruit trees spraying is used.
The mechanism of action of the invention：
Pyraclostrobin has the bactericidal activity of wide spectrum, is mitochondrial respiratory inhibitor, is passed with protection, treatment, infiltration
Lead effect.Simultaneously with good protection and therapeutic action.The bactericide no interactions resistance conventional with other, and killed than conventional
The microbial inoculum lasting period is long.Selectivity with height, it is substantially pollution-free to environment to crop, people and animals and beneficial organism safety.6- benzyls
Adenine phosphate is a kind of basic element of cell division, and its physiological action has：One is to promote cell division and regulate and control its differentiation, promotes wound
Healing；Two is the degraded for delaying protein and chlorophyll, delay senility.
Through lab screening, pyraclostrobin is compounded to have apple branch valsa canker and significantly cooperates with work with 6-benzyl aminopurine
With.Specific test method is as follows：A number of apple branch valsa canker scar is selected, if being scraped the shallow wound in arterial highway in length and breadth to scab
Mouthful, single dose and mixture reagent spray are carried out respectively, scab Cure is observed after 60 days, with the logarithm value of drug concentration (mg/L)
It is independent variable X, is dependent variable Y with the probit value of prevention effect, virulence regression equation is set up respectively, calculates single dose and each proportioning
The EC of mixture50、EC90And its mixture co-toxicity coefficient, compare synergy situation, the results are shown in Table 1.
The pyraclostrobin of table 1. and 6-benzyl aminopurine compounding preventing and treating apple branch valsa canker toxicity test effect
As it can be seen from table 1 pyraclostrobin has obvious increasing to apple branch valsa canker with 6-benzyl aminopurine compounding
Effect is acted on.Especially pyraclostrobin and the mass ratio of both 6-benzyl aminopurines are with 10：0.001~0.025 synergy is notable.
Beneficial effects of the present invention：
Composition of the invention and preparation (including dispersibling oil-suspending agent), pyraclostrobin is cooperateed with 6-benzyl aminopurine
Effect is obvious, can increase substantially preventive effect, overcomes the shortcomings of original preparation preventive effect is poor, the lasting period is short, reduces access times
With the consumption of pyraclostrobin.Composition of the invention and dispersible oil-suspending agent and can be applied to the anti-of apple branch valsa canker
Control.
The oil-suspending agent that dispersibles of the invention is easy to use, overcome the coating of original method using work efficiency it is low, healing time is slow,
The shortcomings of high recurrence rate, retention time of the extension active ingredient on branch, the consumption of pyraclostrobin is reduced, reduce recurrence
Rate, is easy to use, and the using effect of pyraclostrobin greatly improved.
