Fruit tree root rot pesticide control and method
Technical field
The invention belongs to technical field of plant protection, and in particular to a kind of fruit tree root rot pesticide control and method.
Background technology
Root rot is a kind of destructive disease for endangering the fruit trees such as apple, pears, peach, grape.Due in the last few years part fruit
Agriculture fertilising is not scientific and reasonable enough, causes excessive P elements in soil to be absorbed by fruit tree, also produces one to nitrogen
Fixed antagonism, aggravates soil hardening, and permeability is destroyed, and causes fruit tree resistance against diseases significantly to decline.Plus portion
Divide orchard worker to be excessively used and easily cause ammonium hydrogen carbonate and the human and animal excreta without fermentation maturity, stalk for burning root phenomenon etc., also all
Exacerbate a large amount of generations of root rot.
Fruit tree root rot mainly has five kinds of fungus-caused purple striae plumage, lineae ablicantes plumage, Root―rot disease, southern blight and round spot root rot
With bacterial root knot and hairy root disease.Morbidity sticks weight, the orchard of impeded drainage with old orchard, beach or soil property, and arid lacks
Fertilizer, soil hardening, liquid manure are easy to run off, biennial bearing phenomenon serious and the orchard of extensive management is attached most importance to.In addition, other disease pests are endangered
The orchard of evil weight, root rot occurs also serious.The sick main harm root, is occur disease since indivedual supporting roots and fibrous root first
Become, and gradually extend to main root, butt rot degree aggravation over time, the function of root absorption moisture and nutrient by
Decrescence weak, ground nutrient is not enough, shows as wilting, blue or green dry, shrivelled.Root rot is set for fruit tree particularly apple, pears, peach etc.
Wooden is very harmful, and fruit tree once suffers from this after being ill, and gently then side shoot is withered, it is weak to grow(It is commonly called as small old man tree), heavy then whole strain is dead
Die.
At present, root rot preventing and treating is carried out by strengthening orchard management, isolation and the measure such as soil disinfection, medicament pouring root more,
For example, strengthen orchard management including:(1)Applying organic manure, it is to avoid inclined nitrogen fertilizer application;(2)Hypsography low-lying, the viscous weight of soil and underground water
Position orchard high is it is noted that draining;(3)Science is pruned, and sensible load makes tree crown ventilation and penetrating light, prevents biennial bearing phenomenon, is kept
Tree vigo(u)r is healthy and strong;(4)Other pest and disease damages are prevented and treated, prevents day from burning and freeze injury;But the measure can only prevent or reduce the generation of root rot,
Disease plant can not be treated.The method of isolation and soil disinfection is used for preventing and treating the fruit tree for having occurred and that disease, including:
(1)Isolation:The zanjon of more than 1m is dug around lesion, prevents germ from spreading;(2)Soil disinfection:The soil disinfection time with early spring,
Late summer germ is advisable when coming into play, centered on trunk dig 3~5 radiation ditches, depth depending on Main root depth, about 80cm,
By in medicament uniformly dispersing soil, lime sulfur, ambam etc. can be used;But the measure is such as applied using serious poisoning is easily caused accidentally
Fruit tree is caused largely to fall leaves with copper sulphate, ambam etc., and application process is cumbersome.Mancozeb, enemy's sulphur can be used in period of disease
The bactericide pouring root such as sodium, thiophanate methyl, Bravo, but its therapeutic effect is not thorough, and the later stage easily recurs, and fruit product after preventing and treating
Matter declines, and some drug toxicities are strong, and the residual hazard time is long, careless slightly meeting do harm to huamn body in orchard worker's operating process.
