Description
Technical field
The invention belongs to technical field of plant disease biological control.Specifically, the present invention relates to one plant of lichens gemma bars
Bacterium and its application in prevention and treatment grape root rot, and the biological control agent using bacillus licheniformis preparation.
Background technique
Grape root rot, also known as grape round spot root rot.European grape root starts i.e. by this evil of being critically ill after sprouting, generally from plant
Fibrous root morbidity, makes old complaint browning rot, and gradually spreads to meat lateral root, and form a bronzing round spot around fibrous root base portion,
Scab constantly expands, and often rots to reach xylem, and number spot is fused together, and makes cortex easily with woody part from old complaint is gradually
Become dark brown and dead.Since plant callus ability itself is strong, old complaint after death can also sprout new root out, and causing disease, this plays that
Volt.Overground part, which is sprouted, after the onset of usual grapevine seedling root postpones, and the part branch or complete stool after sprouting grow also weaker, leaf
It is small and color is light;When root morbidity is serious, 4~7 leaves of young sprout can wither suddenly, later withered death.
Grape root rot is mainly caused by three kinds of pathogens, respectively Fusarium solani, Fusarium oxysporum and bent angle reaping hook
Bacterium.These types of sickle-like bacteria is all soil inhabitant, saprophytic in the soil, and subterranean pest-insect, the soil to carry disease germs, garden tool set can bands
Disease is propagated.Prevention and treatment to grape root rot, the conventional method of use include traditional chemical prevention, cultivate disease-resistant variety and life
Object prevention and treatment.Chemical prevention such as Bordeaux mixture, improper use will lead to copper ion murder by poisoning or lime phytotoxicity, reduce fruit quality and production
Amount;And disease-resistant variety cultivation period is long, resistance is single, and investment is big;Biological control mainly utilizes beneficial microorganism, passes through life
Competition, antibacterial action, hyperparasitism, cross-protection and induced resistance between object etc. inhibit certain pathogens
Survival and activity, have the advantages that it is nontoxic, pollution-free, do not develop drug resistance, be efficient, show wide application prospect.
Bacillus licheniformis is a kind of Gram-positive bacillus, can produce endogenous spore, heat-resisting resistance is strong, in soil
Earth and plant surface are generally existing.Bacillus licheniformis is a kind of endophyte common in plant, nontoxic to people and animals, no
Pollute environment.The speed of growth is fast, and nutritional need is simple, is easy to survive on the surface of plant, colonizes and breed, production technology letter
Single, preparation stabilization is easy to use, and Storage period is long.Bacillus licheniformis is various to the mechanism of action and mode of phytopathogen.
It mainly include the several respects such as Competition, antibiosis, bacteriolysis and promotion plant growth.It therefore is a kind of ideal biological and ecological methods to prevent plant disease, pests, and erosion
Microorganism.
Summary of the invention

1.5.2 drug effect and security survey
Efficacy survey: investigation 1 time in total, carrying out for 90 days after administration, records each processing group grape root rot morbidity number,
Calculate diseased plant rate and control efficiency.
Drug effect following formula calculates:
1.6 result
(1) control efficiency of the reagent agent to grape root rot
90 days investigation diseased plant numbers after pouring root, table 1 the results show that clear water control diseased plant rate be up to 35.75%, each processing
Diseased plant rate be below clear water control.The biological control agent of the 08220414 bacterium powder containing bacillus licheniformis dilute respectively 500 times,
750 times, the diseased plant rate after 1000 times of pouring roots be respectively 2.68%, 6.72%, 9.32%, 50% multiple-effect spirit wettable powder dilution agent
The diseased plant rate of pouring root is 6.86% after 800 times;The each processing of the biological control agent of 08220414 original powder containing bacillus licheniformis
Control efficiency be respectively 92.50%, 81.20%, 73.93%, wherein dilution 500 times control efficiency it is best.Other processing
There is significant difference in the level of P < 0.05,50% multiple-effect spirit wettable powder is to the control efficiency of grape root rot
80.81%.The harm of grape root rot can be effectively controlled in 08220414 biological control agent of bacillus licheniformis.
The disease incidence and control efficiency of grape root rot after each processing of table 1
Note: with there is same letter to indicate that difference is not significant (P < 0.05) after Duncan Multiple range test after data line.
(2) grape security survey: it is observed that each chemicals treatment district, compared with check plot, grape is generated without phytotoxicity, explanation
08220414 biological control agent of bacillus licheniformis is safe to grape for examination concentration.
Therefore, from the point of view of disease incidence and control efficiency, the biological control of the invention containing bacillus licheniformis 08220414
Preparation has preferable control efficiency to grape root rot, and control efficiency is up to 90% or more after diluting 500 times of applications, hence it is evident that good
In comparison medicament, significant difference.In terms of grape growing way, 08220414 biological control agent of bacillus licheniformis does not have grape growth
