The early prevention and treatment method of ornamental plant droop and the treatment method of middle and later periods
Technical field
The present invention relates to Ornamental Diseases prevention and control field, more particularly to the early prevention and treatment method of ornamental plant droop and
The treatment method of middle and later periods.
Background technology
Droop is a kind of Gardens strain systematicness contagious disease, is propagated with anemophily, rain matchmaker.The pathogenic bacteria master of droop
To be sickle-like bacteria, and infectiousness is strong, pathogenicity rate is high.Pathogen can retain in the invalid tissue of soil and with soil bacteria, by plant
Wound invades, and causes plant branches and leaves to be wilted, and bad spot flow liquid occurs in dry hide, and last whole strain is dead.Droop can be with faster speed
Periphery trees are transmitted to, such as preventing and treating not in time, can cause large area disease.Especially planting trees tree vigo(u)r is weaker, easily infected, makes
Into disease it is even more serious.Mostly at 6783 months, high temperature, high humidity are advantageous to the breeding of pathogen and invaded disease time
Enter;Heavy rain, irrigation can promote the diffusion of pathogen, increase the infection chance of trees.
Cultivation of the preventing and treating for droop typically by selecting the strong kind of disease resistance, selecting suitable growth in the prior art
Ground is planted, wound formation is reduced, reduces the means such as the former infection of bacterium and chemicals treatment to carry out.However, be limited by weather, plantation and
The factor such as growing environment and environmental protection, in practice, chemicals treatment are the most frequently used and effective droop prevention and controls.It is previously used for
Because its toxicity is big, the consideration for environmental protection has stopped production the medicament of droop preventing and treating mostly, and some conventional medicaments are
Using for many years, germ is to which creating the resistance to the action of a drug, and alternative product effect is also undesirable.For example, early stage Landscape Industry is treated
Silk tree droop uses agricultural chemicals ambam, and it is strength systemics, severe toxicity, has stopped production.In droop early stage, Dai Sen is used
Aqueous ammonium pouring root, there is obvious therapeutic effect.With the stopping production of ambam, into substitute, these are replaced for normal sterile agent
Although there is certain systemic action for product, it is impossible to which control droop completely causes harm.Summary reason, the droop of ornamental trees and shrubs
There is unmanageable trend in recent years.
