Description

A kind of composition and application process that wheat powdery mildew is treated based on guaiacol

Technical field

The present invention relates to pesticide field, more particularly to application and administration side of the guaiacol mixture in preventing and treating wheat powdery mildew Method.

Background technology

Guaiacol is a kind of white or slightly yellow crystallization or colourless to pale yellow transparent oily liquids, there is special aroma Taste, scientific name guaiacol, glycerin ether, guaiacol glycerol ether, adjacent hydroxyl glycerin ether etc., guaiaci lignum is present in nature It is a kind of important fine-chemical intermediate in resin, pine tar and hardwood empyreumatic oil, is widely used in medicine, spices and dyestuff Synthesis, rarely have the document and technology for using it for other field in existing production and living.

The content of the invention

The present invention develops guaiacol in agriculture field, the especially application in terms of wheat powdery mildew is prevented and treated, and There is provided its application process, blank of the guaiacol in the field purposes has been filled up, it is of the invention by guaiacol and pyrazoles ether bacterium Composition is made in ester, and phase composition includes guaiacol and pyraclostrobin, the mass ratio of the guaiacol and pyraclostrobin For 1/10-10.

Preferably, the guaiacol and pyraclostrobin ratio are 1/2-2.

Preferably, wherein Determination of Guaiacol is 10%, pyraclostrobin content is 20%.

Preferably, also including the one or more in dispersant, sticker, bleeding agent, emulsifying agent, preservative, antifreezing agent.

Preferably, the pyraclostrobin and guaiacol mixture are processed into one in suspending agent, aqua, soluble liquid Kind.

Preferably, the suspending agent includes sodium alginate 0.1%-25%, anion surfactant；The anion table Face activating agent includes lignosulfonates 0.1%-25%.

Preferably, treating the application process of the composition of wheat powdery mildew based on guaiacol；Comprise the following steps：

S1., the pyraclostrobin and guaiacol mixture are processed into one kind in suspending agent, aqua, soluble liquid；

S2. dispenser, takes the guaiacol decoction that step S1 is configured to carry out spray pesticide to wheat.

Preferably, spray value is 300~600L/ hm in the step S2², atomisation pressure is 0.3~0.8kPa, dispenser Number of times is 1~2 time.

The guaiacol decoction mechanism of action：

（1）Suppress RNA reverse transcriptase RTASE activity, prevent virion from synthesizing；

（2）Absorption of the virion on cell is prevented, virus is reduced and contaminates probability；

(3) oxidation resistance in enhancing plant, reduces injury of the virus dip-dye to plant；

(4) resistance against diseases of plant is improved.

The present invention develops guaiacol in preventive and therapeutic effect of the agriculture field particularly with wheat powdery mildew, can be made into conventional The formulations of pesticide, it is mashed up in proportion with pyraclostrobin, prevention effect more more preferable than single dose is reached, while adding chitosan and other Auxiliary agent makes the increase of guaiacol decoction viscosity, can preferably be attached to crop surface, beneficial to drug absorption, meanwhile, chitosan There is certain auxiliary antibacterial, the effect of desinsection, and moderate cost, it is worthy to be popularized.

Embodiment

Embodiment one

Guaiacol and pyraclostrobin are made to the composition for the treatment of wheat powdery mildew, its composition includes guaiacol and pyrazoles Kresoxim-methyl, the mass ratio of the guaiacol and pyraclostrobin is 1/10-10.

More specifically, the guaiacol and pyraclostrobin mass ratio are 1/2-2.

More specifically, wherein Determination of Guaiacol is 10%, and pyraclostrobin content is 20%.

More specifically, in addition to one kind in dispersant, sticker, bleeding agent, emulsifying agent, preservative, antifreezing agent or It is a variety of.

More specifically, pyraclostrobin and the guaiacol mixture is processed into suspending agent, aqua, soluble liquid One kind.

More specifically, the suspending agent includes sodium alginate 0.1%-25%, anion surfactant；It is described it is cloudy from Sub- surfactant includes lignosulfonates 0.1%-25%.

More specifically, the application process of the composition of wheat powdery mildew is treated based on guaiacol；Comprise the following steps：

More specifically, spray value is 300~600L/ hm in the step S2², atomisation pressure is 0.3~0.8kPa, Spraying times are 1~2 time.

Embodiment two

Guaiacol, pyraclostrobin single dose are determined using Plating, and two kinds of single doses press 1: 10,1: 5,1:3、1:2、1∶1、 9 kinds of mixture samples of 2: 1,3: 1,5: 1,10: 1 ratio composition to the Antibacterial Activity of wheat powdery mildew pathogenic bacteria mycelial growth, Record and compare the bacteriostasis rate that each drug concentration suppresses wheat powdery mildew pathogenic bacteria mycelial growth.

Result of the test shows that pyraclostrobin has preferable antibacterial work to the mycelial growth of wheat powdery mildew pathogenic bacteria Property, and guaiacol is relatively low to the bacteriostatic activity of wheat powdery mildew pathogenic bacteria.Pyraclostrobin is to wheat powdery mildew pathogenic bacteria Bacteriostatic activity is significantly higher than the bacteriostatic activity of guaiacol.

With probit analysis, calculate pyraclostrobin, guaiacol and its mixture and suppress wheat powdery mildew pathogenic bacteria bacterium The toxicity regression formula of silk growth.Result of calculation shows that pyraclostrobin has preferably to the mycelial growth of wheat powdery mildew pathogenic bacteria Inhibitory activity, guaiacol is substantially less than pyraclostrobin to the inhibitory activity of wheat powdery mildew pathogenic bacteria mycelial growth.

With the EC of each mixture₅₀Value is calculated the co-toxicity coefficient of mixture by the abundant methods of Sun Yun, is as a result shown, when pyraclostrobin is with being cured The wooden phenol of wound is with 1: 10,1: 5,1:During 3 mixture, the CTC values of its mixture are less than 80, illustrate its mixture pyraclostrobin and guaiacol By 1: 10,1: 5,1:3 mixtures show as antagonism to the bacteriostatic activity of wheat powdery mildew pathogenic bacteria；When pyraclostrobin is with being cured The wooden phenol of wound is with 1:2nd, 1: 1, during 2: 1 mixture, the CTC values of its mixture are all higher than 120, and with 2:1 is highest, illustrates pyraclostrobin Synergistic effect is shown as to the bacteriostatic activity of wheat powdery mildew pathogenic bacteria in these ratio mixtures with guaiacol；When pyrazoles ether bacterium Ester is with guaiacol with 10: 1,5:1st, during 3: 1 mixture, the CTC values of its mixture are more than 80 and less than 120, illustrate pyraclostrobin 10: 1,5 are pressed with guaiacol:1st, 3: 1 ratio mixtures show as summation action to the bacteriostatic activity of wheat powdery mildew pathogenic bacteria, because This, both composition pyraclostrobin and guaiacol of configuration guaiacol pyraclostrobin treatment wheat powdery mildew ratio 1:2nd, choose among 1: 1,2: 1, bactericidal activity is higher, wherein with 2:1 is optimum proportioning.

Preferred embodiments of the present invention are these are only, therefore the scope that the present invention is implemented can not be limited according to this, i.e., according to the present invention Equivalence changes and decoration that description is made, should all belong in the range of present invention covering.
