The invention discloses a kind of composition and application process that pepper anthracnose is treated based on guaiacol, guaiacol is applied to agriculture field, composition is made by a certain percentage with Difenoconazole, for treating pepper anthracnose, guaiacol new application is developed, pepper anthracnose can effectively be treated, the resistance against diseases of crop is improved, and it is compared with other existing agricultural chemicals single doses, and prevention effect is more preferable, production cost is relatively low, is worthy to be popularized.

Description

A kind of composition and application process that pepper anthracnose 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 pepper anthracnose 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 pepper anthracnose 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 phenyl ether methyl cyclic Composition is made in azoles, and phase composition includes guaiacol and Difenoconazole, the mass ratio of the guaiacol and Difenoconazole For 1/10-10.

Preferably, the guaiacol and Difenoconazole ratio are 1/3-3.

Preferably, wherein Determination of Guaiacol is 30%, Difenoconazole content is 10%.

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

Preferably, the Difenoconazole 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 pepper anthracnose based on guaiacol；Comprise the following steps：

S1., the Difenoconazole 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 paddy rice.

Preferably, spray value is 200~500L/ 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 pepper anthracnose, can be made into conventional The formulations of pesticide, it is mashed up in proportion with Difenoconazole, 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 Difenoconazole are made to the composition for the treatment of pepper anthracnose, its composition includes guaiacol and phenylate Methyl cyclic-azole, the mass ratio of the guaiacol and Difenoconazole is 1/10-10.

More specifically, the guaiacol and Difenoconazole mass ratio are 1/3-3.

More specifically, wherein Determination of Guaiacol is 30%, and Difenoconazole content is 10%.

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, Difenoconazole 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 pepper anthracnose is treated based on guaiacol；Comprise the following steps：

More specifically, spray value is 200~500L/ hm in the step S2², atomisation pressure is 0.3~0.8kPa, Spraying times are 1~2 time.

Embodiment two

Guaiacol, Difenoconazole single dose are determined using Plating, and two kinds of single doses are by 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 pepper anthracnose pathogenic bacteria mycelial growth, Record and compare the bacteriostasis rate that each drug concentration suppresses pepper anthracnose pathogenic bacteria mycelial growth.

Result of the test shows that Difenoconazole has preferable antibacterial work to the mycelial growth of pepper anthracnose pathogenic bacteria Property, and guaiacol is relatively low to the bacteriostatic activity of pepper anthracnose pathogenic bacteria.Difenoconazole is to pepper anthracnose pathogenic bacteria Bacteriostatic activity is significantly higher than the bacteriostatic activity of guaiacol.

With probit analysis, calculate Difenoconazole, guaiacol and its mixture and suppress pepper anthracnose pathogenic bacteria bacterium The toxicity regression formula of silk growth.Result of calculation shows that Difenoconazole has preferably to the mycelial growth of pepper anthracnose pathogenic bacteria Inhibitory activity, guaiacol is substantially less than Difenoconazole to the inhibitory activity of pepper anthracnose 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 Difenoconazole is with being cured When the wooden phenol of wound is with 1: 10 mixture, the CTC values of its mixture are less than 80, illustrate that its mixture Difenoconazole is mixed by 1: 10 with guaiacol The bacteriostatic activity of pairing pepper anthracnose pathogenic bacteria shows as antagonism；When Difenoconazole and guaiacol with 1: 5,1: 3, 1: 2,1: 1,2: 1,3: 1,5: 1 mixture when, the CTC values of its mixture are all higher than 120, and are highest with 1: 3, illustrate Difenoconazole Synergistic effect is shown as to the bacteriostatic activity of pepper anthracnose pathogenic bacteria in these ratio mixtures with guaiacol；Work as phenyl ether methyl cyclic When azoles and guaiacol are with 10: 1 mixture, the CTC values of its mixture are more than 80 and less than 120, illustrate Difenoconazole and guaiaci lignum Phenol shows as summation action in 10: 1 ratio mixtures to the bacteriostatic activity of pepper anthracnose pathogenic bacteria, therefore, configures guaiaci lignum Both the composition of phenol Difenoconazole treatment pepper anthracnose ratios are among 1: 5,1: 3,1: 2,1: 1,2: 1,3: 1,5: 1 Choose, bactericidal activity is higher, wherein being optimum proportioning with 1: 3.

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.
