Face activating agent includes lignosulfonates 0.1%-25%.
Preferably, treating the application process of the composition of alternaria leaf spot of crucifers based on guaiacol；Comprise the following steps：
S1., the Mancozeb 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 brassicaceous vegetable.
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 alternaria leaf spot of crucifers, can be made into
Common pesticides formulation, it is mashed up in proportion with Mancozeb, prevention effect more more preferable than single dose is reached, while adding chitosan and its
His auxiliary agent makes the increase of guaiacol decoction viscosity, can preferably be attached to crop surface, beneficial to drug absorption, meanwhile, chitosan
Also there is certain auxiliary antibacterial, the effect of desinsection, and moderate cost, it is worthy to be popularized.
Embodiment
Embodiment one
Guaiacol and Mancozeb are made to the composition for the treatment of alternaria leaf spot of crucifers, its composition includes guaiacol and generation
Gloomy MnZn, the mass ratio of the guaiacol and Mancozeb is 1/10-10.
More specifically, the guaiacol and Mancozeb mass ratio are 1/3-3.
More specifically, wherein Determination of Guaiacol is 30%, and Mancozeb content is 10%.
More specifically, also including one kind in dispersant, sticker, bleeding agent, emulsifying agent, preservative, antifreezing agent or
It is a variety of.
More specifically, Mancozeb and the guaiacol mixture is processed into suspending agent, aqua, soluble liquid
It is a kind of.
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 alternaria leaf spot of crucifers is treated based on guaiacol；Including following
Step：
S1., the Mancozeb 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 brassicaceous vegetable.
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, Mancozeb single dose are determined using Plating, and two kinds of single doses press 1: 10,1: 5,1: 3,1: 2,1: 1,2:
1st, antibacterial work of the 9 kinds of mixture samples of 3: 1,5: 1,10: 1 ratio composition to alternaria leaf spot of crucifers pathogenic bacteria mycelial growth
Power, records and compares the bacteriostasis rate that each drug concentration suppresses alternaria leaf spot of crucifers pathogenic bacteria mycelial growth.
Result of the test shows that Mancozeb has preferable antibacterial work to the mycelial growth of alternaria leaf spot of crucifers pathogenic bacteria
Property, and guaiacol is relatively low to the bacteriostatic activity of alternaria leaf spot of crucifers pathogenic bacteria.Mancozeb is caused to alternaria leaf spot of crucifers
The bacteriostatic activity of germ is significantly higher than the bacteriostatic activity of guaiacol.
With probit analysis, calculate Mancozeb, guaiacol and its mixture and suppress alternaria leaf spot of crucifers pathogenic bacteria
The toxicity regression formula of mycelial growth.Result of calculation shows that Mancozeb has to the mycelial growth of alternaria leaf spot of crucifers pathogenic bacteria
Preferable inhibitory activity, guaiacol is substantially less than maneb to the inhibitory activity of alternaria leaf spot of crucifers pathogenic bacteria mycelial growth
Zinc.
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 Mancozeb is with more creating
When wooden phenol is with 1: 10 mixture, the CTC values of its mixture are less than 80, illustrate its mixture Mancozeb with guaiacol by 1: 10 mixture pair
The bacteriostatic activity of alternaria leaf spot of crucifers pathogenic bacteria shows as antagonism；When Mancozeb and guaiacol are with 1: 5,1: 3,1:
2nd, 1: 1,2: 1,3: 1, during 5: 1 mixture, the CTC values of its mixture are all higher than 120, and are highest with 1: 3, illustrate Mancozeb with more
The wooden phenol of wound shows as synergistic effect in these ratio mixtures to the bacteriostatic activity of alternaria leaf spot of crucifers pathogenic bacteria；Work as Mancozeb
During with guaiacol with 10: 1 mixture, the CTC values of its mixture are more than 80 and less than 120, illustrate that Mancozeb is pressed with guaiacol
10: 1 ratio mixtures show as summation action to the bacteriostatic activity of alternaria leaf spot of crucifers pathogenic bacteria, therefore, configure guaiaci lignum
Both compositions ratio of phenol Mancozeb treatment alternaria leaf spot of crucifers 1: 5,1: 3,1: 2,1: 1,2: 1,3: 1,5: 1 it
Middle to 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.
