Description
Technical field
The present invention relates to pesticide field, more specifically relate to the using method of a kind of novel agrochemical auxiliary agent in mancozeb class wetting powder and the preparation method of this wetting powder.
Background technology
Mancozeb is the co-ordination complex of maneb and zinc ion, is the wider protective fungicide of a kind of fungicidal spectrum.Also be the kind most widely used in same series bactericidal agent, consumption is maximum, its mechanism of action is mainly to suppress the oxidation of pyruvic acid in thalline and reach bactericidal object.Be mainly used in preventing and treating the multiple diseases of various crop, effective to multiple diseases such as the downy mildew on fruit tree, vegetables, anthracnose, early blight, its normal and multiple systemic fungicide mixture, to expand fungicidal spectrum, delays pathogen bactericide is produced to resistance simultaneously.
Pesticide wettable is a kind of very important formulation in pesticidal preparations.Agricultural chemicals will be brought into play high service efficiency, first will make pesticide solution on target substance, fully sprawl and be detained.This just requires liquid to have lower surface tension, has good wetability and permeability on target surface.Otherwise will cause fluid loss, will inevitably affect like this drug effect, directly environment caused to serious pollution.Meanwhile, if drug effect is not high, peasant will inevitably strengthen dispenser dynamics and intensity, has both caused the increase of agricultural chemicals use cost, has also caused the severe overweight of residue of pesticide.Therefore, improving agricultural chemicals availability is to reduce drug cost, reduces environmental pollution, reduces the basic of residue of pesticide.
Organosilicon table surfactant is existing more patent report in other field, but in pesticide field, uses three patents such as only having at present a kind of liquid pesticidal formulations that contains avermectins and organic silicon surfactant of applicant application and preparation method thereof, a kind of pesticide water dispersible granules that contains organic silicon surfactant and preparation method thereof, a kind of agricultural chemicals suspension agent that contains organic silicon surfactant and preparation method thereof open.Compared with conventional surfactant, organic silicon surfactant can effectively reduce the surface tension of water, reduces the contact angle of liquid and biological target, has the infiltration capacity that good wetability, stronger adhesion, superpower extended capability are become reconciled.Can make liquid arrive the place that is difficult to soak, increase spraying coverage rate, promote that liquid absorbs fast.Can improve the resistance of rainwater washing against ability of liquid, improve the effective rate of utilization of agricultural chemicals, reduce agricultural chemicals injected volume simultaneously.As a kind of novel, efficient insecticides adjuvant, it has broad application prospects in pesticide industry.
Therefore, in the present invention novel surfactant-organic silicon surfactant is joined in pesticide wettable, made a kind of physical stability, chemical stability, all good pesticide wettables of preparation effect.

embodiment five: preparation physicochemical property Efficiency assessment
To adding the preparation of organic silicon surfactant described in the present invention, the assay method of every evaluation index is as follows: (in following experiment, CK all adopts the white carbon of equivalent to substitute organic silicon surfactant, all the other recipe ingredients and of the present invention same)
1, surface tension ()
The mensuration of medical liquid surface tension adopts platinum plate method.The surface tension of liquid is during lower than the surface free energy of target, and liquid is just likely at target moistened surface with sprawl.
2, dynamic contact angle (q)
Dynamic contact angle adopts contact angle measurement to measure, and adopts video method.The liquid that dynamic contact angle is little is strong to wettability on selected target.
3, drop expanding area (S)
The mensuration of drop expanding area adopts integration method.Drop expanding area has directly represented the extended capability of liquid on target surface, and drop expanding area is large, shows that preparation spreadability is good.
Table 1 preparation Efficiency assessment of the present invention (dilution 1000 ×)
| Mensuration project | CK | FORMULATION EXAMPLE 1 |
| Surface tension (mN/m) | 37.3 | 22.1 |
| Contact angle when 30s (°) | 56.2 | 30.8 |
| Expansion radius (mm) when 30s | 2.35 | 4.31 |
The Efficiency assessment (dilution 1000 ×) of table 2 preparation of the present invention
| Mensuration project | CK | FORMULATION EXAMPLE 2 |
| Surface tension (mN/m) | 37.9 | 22.3 |
| Contact angle when 30s (°) | 60.5 | 34.2 |
| Expansion radius (mm) when 30s | 2.86 | 4.28 |
The Efficiency assessment (dilution 1000 ×) of table 3 preparation of the present invention
| Mensuration project | CK | FORMULATION EXAMPLE 3 |
| Surface tension (mN/m) | 38.6 | 22.7 |
| Contact angle when 30s (°) | 61.4 | 33.8 |

six: 69% mancozeb dimethomorph wetting powder field efficacy control efficiency of embodiment are evaluated
To adopt the agricultural chemicals wettability pulvis of the present invention's production to compare the advance of the pesticide wettable that does not add organic silicon surfactant production in order further verifying, to have carried out respectively field control effectiveness test, described in employing method and result are exemplified below.Below, in experiment, CK adopts the white carbon of equivalent to substitute organic silicon surfactant, all the other recipe ingredients and of the present invention same.
Trial crops is cucumber, and controlling object is downy mildew, by 600 times of preparation dilutions, by 100 grams of even spraying of amount of formulation for mu, in the dispenser of downy mildew their early stage once, after 7 days, executes medicine for the second time, executes medicine for the third time, altogether dispenser three times after 14 days.Each processing in triplicate, is investigated for the third time 7 days preventive effects after medicine, the results are shown in following table.Because the formula that does not exist mancozeb isoreactivity composition to contain organic silicon surfactant (active component adopts the white carbon of equivalent to replace) does not have preventive effect, so organic silicon surfactant can be worked in coordination with the preventive effect that increases mancozeb isoreactivity composition.
Table 4 69% mancozeb dimethomorph wetting powder is prevented and treated the comparison of downy mildew effect
