Abstract
The present invention provides a kind of bactericidal composition for preventing and treating crop wilt disease and its application, and active constituent includes hymexazol and benzothiostrobin, and the weight proportion of hymexazol and benzothiostrobin is 1: 70-70: 1；The bactericidal composition can be used for the prevention and treatment of watermelon, muskmelon, cotton, banana, tomato, cucumber, potatoes and other crops wilt disease.
Description
Technical field
The invention belongs to pesticide fields, and in particular to a kind of bactericidal composition for preventing and treating crop wilt disease and its answer
With.
Background technique
China is watermelon largest production state, but disease is serious in process of production for watermelon, is especially caused harm with watermelon blight
It is the most serious.Watermelon blight is root wound and Gen Mao growing point to be infected by Fusarium oxysporum f. sp. niveum, and then destroy
The vascular bundle of its root, stem and leaf makes watermelon plant absorb and transport moisture function and loses, it is withered dead to ultimately cause watermelon plant
It dies.Graft technology is one of prevention and treatment most economical effective method of the disease.But in recent years, as the continuous cropping of Grafted Watermelon increases
Add, the generation of Grafted Watermelon wilt disease is also increasingly severe, and the local disease incidence of severe disease is up to 30%-50%.Due to western at present
Cucurbit wilt means of prevention is unable to efficient sterilizing, and disease-resistant variety breeding difficulty is big, the continuous differentiation of pathogen biological strain, anti-medicine
Property, pathogenicity enhancing, the reasons such as agro-farming technical level is low make a big impact to the production of China's watermelon, serious contusion life
The enthusiasm of production person.Therefore the effective agent of screening prevention and treatment watermelon blight is extremely urgent.
Hymexazol is a kind of systemic fungicide, has interior suction and conduction, while being a kind of soil sterilants again, right
There is good control efficiency by various plant soil-borne diseases such as pythium spp, seedling corruption bacterium, sickle-like bacteria, rhizoctonia, root shell bacterium, apply
After in soil, can in soil iron, in conjunction with aluminium ion, the sprouting of germ spore can be inhibited, can be absorbed simultaneously by the root system of plant
It is moved in root system, generates 2 kinds of glucosides in plant intracellular metabolite, be improved plant physiology activity, the tiller of promotion root, increase root hair
The effect of quantity and plant strain growth.
Benzothiostrobin is a kind of novel Strobilurins class fungicide, and the mode of action is mainly by multiple with mitochondria
Close object III in cytochrome b (cytb) the site Qo in conjunction with and prevent the electron transmission in mitochondria, inhibit the breathing of pathogen
Effect.Benzothiostrobin has wider fungicidal spectrum, and effective to the bacterial strain for generating resistance, has efficient, less toxic, environmental-friendly etc.
Feature.
In pesticide research, the active constituent of different cultivars is compounded, is that prevention and treatment the very common of resistance disease is done
Method.Compound synergic is formulated well, due to significantly improving practical control efficiency, the usage amount of pesticide is reduced, thus significantly
The generation for having delayed disease drug resistance, be the important means of integrated control disease.
Summary of the invention
To solve problems of the prior art, the present invention provide it is a kind of with synergistic function for prevent and treat make
The bactericidal composition of object wilt disease and its application.
Technical solution provided by the invention is as follows:
It is a kind of that for preventing and treating the bactericidal composition of crop wilt disease, active constituent includes hymexazol and benzothiostrobin, and
The weight proportion of hymexazol and benzothiostrobin is 1: 70-70: 1.It is preferred that 1: 35-50: 1.More select 1: 5-15: 1.
The weight percentage of active constituent described in bactericidal composition of the present invention is 1-90%.It is preferred that 10-
60%.
Bactericidal composition dosage form of the present invention can be missible oil, wettable powder, suspending agent, aqueous emulsion, water-dispersible grain
Agent, granule etc..
Auxiliary element in bactericidal composition preparation can be solvent, dispersing agent, emulsifier, wetting agent, stabilizer, antifreeze
Agent, thickener, defoaming agent and adhesive and other be beneficial to the effective component substance that stable and drug effect plays in the formulation, can
It is one of or several.
Bactericidal composition of the present invention is used to prevent and treat the purposes of crop wilt disease.It is preferred for watermelon, muskmelon, cotton
Flower, banana, tomato, cucumber, potatoes and other crops.It is more preferably used for watermelon blight.
Compared with prior art, the invention has the following beneficial effects:
Two kinds of fungicide of hymexazol and benzothiostrobin are compounded, since structure difference between the two is larger, effect
Mechanism is different, and the application of compound preparation can delay generation and development of the germ to single dose resistance.The combination of the two compounding simultaneously
Object shows preferable synergistic effect in certain ratio range, and the bactericidal effect of mixed composition has obviously compared with single dose
It improves, to reduce pharmaceutical use, reduces peasant household's drug cost, reduce the adverse effect to environment.
