Abstract
The present invention provides a kind of bactericidal composition and its application for being used to prevent and treat crop droop, and active component 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 preventing and treating of watermelon, muskmelon, cotton, banana, tomato, cucumber, potatoes and other crops droop.
Description
Technical field
The invention belongs to pesticide field, and in particular to it is a kind of be used for prevent and treat crop droop bactericidal composition and its should
With.
Background technology
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 to infect root wound and Gen Mao growing points by Fusarium oxysporum f. sp. niveum, and then is destroyed
The vascular bundle of its root, stem and leaf, watermelon plant is absorbed and transport moisture function and lose, it is withered dead to ultimately cause watermelon plant
Die.Graft technology is to prevent and treat one of most economical effective method of the disease.But in recent years, increase with the continuous cropping of Grafted Watermelon
Add, the generation of Grafted Watermelon droop is also increasingly severe, and the local incidence of disease for weight of falling ill is up to 30%-50%.Due to western at present
Cucurbit wilt means of prevention is unable to efficient sterilizing, and disease-resistant variety seed selection difficulty is big, the continuous differentiation of pathogen biological strain, anti-medicine
Property, pathogenicity enhancing, the reasons such as agro-farming technical merit 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 preventing and treating watermelon blight is extremely urgent.
Hymexazol is a kind of systemic fungicide, has interior suction and conduction, while is a kind of soil sterilants again, right
There is good prevention effect by various plant soil-borne diseases such as pythium spp, seedling corruption bacterium, sickle-like bacteria, rhizoctonia, root shell bacterium, apply
After in soil, it can be combined with the iron in soil, aluminium ion, the sprouting of germ spore can be suppressed, can be by the Root Absorption of plant simultaneously
Moved in root system, 2 kinds of glucosides are produced in plant intracellular metabolite, be improved plant physiology activity, the tiller for promoting root, increase root hair
The effect of quantity and plant strain growth.
Benzothiostrobin is a kind of new Strobilurins series bactericidal agents, and its mode of action with mitochondria mainly by answering
In compound III the Qo sites of cytochrome b (cytb) with reference to and prevent the electron transmission in mitochondria, suppress the breathing of pathogen
Effect.Benzothiostrobin has wider fungicidal spectrum, and the bacterial strain to producing resistance is effective, has efficient, less toxic, environment-friendly etc.
Feature.
In pesticide research, the active component of different cultivars is compounded, is that preventing and treating the very common of resistance disease is done
Method.Compound synergic is formulated well, due to significantly improving actual prevention effect, reduces the usage amount of agricultural chemicals, so as to significantly
The generation for having delayed disease drug resistance, be integrated control disease important means.
The content of the invention
To solve problems of the prior art, present invention offer is a kind of to be made with synergistic function for preventing and treating
The bactericidal composition of thing droop and its application.
Technical scheme provided by the invention is as follows：
A kind of bactericidal composition for being used to prevent and treat crop droop, active component include 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 component described in bactericidal composition of the present invention is 1-90%.It is preferred that 10-
60%.
Bactericidal composition formulation 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, dispersant, emulsifying agent, wetting agent, stabilizer, antifreeze
Agent, thickener, defoamer and adhesive, and other be beneficial to active ingredient in the formulation stablize and drug effect play material, can
For one of which or several.
Bactericidal composition of the present invention is used for the purposes for preventing and treating crop droop.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 present invention has the advantages that：
Two kinds of bactericide of hymexazol and benzothiostrobin are compounded, because structure difference therebetween is larger, effect
Mechanism is different, and the application of complex preparation can delay generation and development of the germ to single dose resistance.The combination of the two compounding simultaneously
Thing shows preferable synergistic effect in certain ratio range, and the bactericidal effect of mixed composition has substantially compared with single dose
Improve, so as to reduce medicament usage amount, reduce peasant household's drug cost, reduce the harmful effect to environment.
