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 tobacco leaf spot 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 kresoxim-methyl system
Into composition, phase composition includes guaiacol and kresoxim-methyl, and the mass ratio of the guaiacol and kresoxim-methyl is 1/10-10.
Preferably, the guaiacol and kresoxim-methyl ratio are 1-3.
Preferably, wherein Determination of Guaiacol is 20%, kresoxim-methyl content is 10%.
Preferably, also including the one or more in dispersant, sticker, bleeding agent, emulsifying agent, preservative, antifreezing agent.
Preferably, the kresoxim-methyl and guaiacol mixture are processed into one kind in suspending agent, aqua, soluble liquid.
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 tobacco leaf spot based on guaiacol；Comprise the following steps：
S1., the kresoxim-methyl 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 tobacco.
Preferably, spray value is 300~400L/ hm in the step S22, atomisation pressure is 0.3~0.8kPa, dispenser
Number of times is 1~3 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 tobacco leaf spot, can be made into conventional
The formulations of pesticide, it is mashed up in proportion with kresoxim-methyl, prevention effect more more preferable than single dose is reached, while adding chitosan and other auxiliary agents
Make the increase of guaiacol decoction viscosity, can preferably be attached to crop surface, beneficial to drug absorption, meanwhile, chitosan also has one
Fixed auxiliary is antibacterial, the effect of desinsection, and moderate cost, is worthy to be popularized.
Embodiment
Embodiment one
Guaiacol and kresoxim-methyl are made to the composition for the treatment of tobacco leaf spot, its composition includes guaiacol and kresoxim-methyl,
The mass ratio of the guaiacol and kresoxim-methyl is 1/10-10.
More specifically, the guaiacol and kresoxim-methyl mass ratio are 1-3.
More specifically, wherein Determination of Guaiacol is 20%, and kresoxim-methyl 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, kresoxim-methyl and the guaiacol mixture is processed into one in suspending agent, aqua, soluble liquid
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 tobacco leaf spot is treated based on guaiacol；Comprise the following steps：
S1., the kresoxim-methyl 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 tobacco.
More specifically, spray value is 300~400L/ hm in the step S22, atomisation pressure is 0.3~0.8kPa,
Spraying times are 1~3 time.
Embodiment two
Guaiacol, kresoxim-methyl single dose are determined using Plating, and two kinds of single doses press 1: 10,1: 5,1:3、1:2、1∶1、2∶1、
9 kinds of mixture samples of 3: 1,5: 1,10: 1 ratio composition are to the Antibacterial Activity of tobacco leaf spot pathogenic bacteria mycelial growth, record
And relatively more each drug concentration suppresses the bacteriostasis rate of tobacco leaf spot pathogenic bacteria mycelial growth.
Result of the test shows that kresoxim-methyl has preferable bacteriostatic activity to the mycelial growth of tobacco leaf spot pathogenic bacteria, and
Guaiacol is relatively low to the bacteriostatic activity of tobacco leaf spot pathogenic bacteria.Kresoxim-methyl shows to the bacteriostatic activity of tobacco leaf spot pathogenic bacteria
Write the bacteriostatic activity higher than guaiacol.
With probit analysis, calculate kresoxim-methyl, guaiacol and its mixture and suppress the life of tobacco leaf spot pathogenic bacteria mycelia
Long toxicity regression formula.Result of calculation shows that kresoxim-methyl has to the mycelial growth of tobacco leaf spot pathogenic bacteria preferably to be suppressed to live
Property, guaiacol is substantially less than kresoxim-methyl to the inhibitory activity of tobacco leaf spot 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 kresoxim-methyl and guaiaci lignum
When phenol is with 1: 10,1: 5 mixture, the CTC values of its mixture are less than 80, illustrate its mixture kresoxim-methyl with guaiacol by 1: 10 mixture pair
The bacteriostatic activity of tobacco leaf spot pathogenic bacteria shows as antagonism；When kresoxim-methyl and guaiacol are with 1:3、1:2nd, 1: 1 mixture
When, the CTC values of its mixture are all higher than 120, and with 1:2 be highest, illustrates kresoxim-methyl and guaiacol in these ratio mixtures pair
The bacteriostatic activity of tobacco leaf spot pathogenic bacteria shows as synergistic effect；When kresoxim-methyl and guaiacol are with 10: 1 mixture, it is mixed
The CTC values of agent are more than 80 and less than 120, illustrate kresoxim-methyl with guaiacol by 10: 1,2: 1,3:1、5:1 ratio mixture is to tobacco
The bacteriostatic activity of leaf spot pathogenic bacteria shows as summation action, therefore, configuration guaiacol kresoxim-methyl treatment tobacco leaf spot
Composition kresoxim-methyl and both guaiacol ratio 1:3、1:2nd, choose among 1: 1, bactericidal activity is higher, wherein with 1:2
For 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.
