Description
Technical field
The present invention relates to a kind of medicament of anti-tobacco diseases, more particularly to a kind of anti-tobacco weather-fleck combination agent.
Background technology
Tobacco is referred to as weather pinta or weather spot disease by the cause harm noninfectious disease of initiation of ozone.Cigarette strain seedling stage,
Adult plant can fall ill.Blade easily occurs when entering fast-growth to physiological maturity and changeable weather anomaly.Scab is normal
Master pulse and lateral vein both sides are concentrated on, on the blade extended, is appeared near blade tip more, is just occurred in face of blade many
Intensive irregular water stain shape stigma.In susceptible flue-cured tobacco cultivars, intensive spot can cause blade large area is withered to come off,
It is aggrieved heavier to approach the blade of physiological maturity.The disease generally occurs in recent years, and especially south occurs more, and harm is serious.Should
Although disease does not infect, the influence sometimes to tobacco production and quality is even bigger than the infectious disease on tobacco leaf.
Effectively control the sick medicament imperative therefore, finding.
The content of the invention
It is an object of the invention to provide a kind of anti-tobacco weather-fleck combination agent, the incidence of disease and the state of an illness can be significantly reduced
Index, while the chlorophyll content in tobacco leaf can be improved.
The present invention is achieved through the following technical solutions：
Anti- tobacco weather-fleck combination agent, include the raw material of following weight proportioning：
Diethyl aminoethyl hexanoate 70-90 parts, Difenoconazole 45-65 parts, purslane extract 18-30 parts, HUICAI extract 12-26 parts；Its
Production technology is：
1）Diethyl aminoethyl hexanoate and Difenoconazole 900-1000 parts by weight of ethanol are dissolved；
2）Purslane extract and HUICAI extract 520-595 parts by weight mixed solvent are dissolved；
3）By step 2）Obtained mixed solution is added to step 1）In obtained mixed solution, stir, produce.
The preparation method of the purslane extract is：By the quality point of 200 parts by weight of dried purslane herb
Number is extracted for 15-30% ethanol solution, and Extracting temperature is 60-70 DEG C, is extracted 2-3 times, each 3-5h, merges extract solution,
Filter cleaner, filtrate are concentrated and dried after standing 24-30h, obtain powdered purslane extract；
The preparation method of the HUICAI extract is：Dried grey dish herb is crushed, then the mass fraction with 200 parts by weight
4-6d, leaching liquor filtering are soaked in closed container for 5-12% ethanol solution, filtrate obtains powdered ash after being concentrated and dried
Dish extract；
The quality group of the mixed solvent turns into the ethanol solution that mass fraction is 24.8%：Methanol：Chloroform=1：（1.2-1.9）：
（15.3-17.4）；
Diethyl aminoethyl hexanoate is a kind of high energy plant growth regulator, can improve the activity of plant peroxidases and nitrate reductase, carry
The content of high chlorophyll, accelerate photosynthetic speed, promote the division and elongation of plant cell, promote the development of root system, regulation is in vivo
The balance of nutrient.Difenoconazole is that security is higher in triazole bactericidal agent, is widely used in the work such as fruit tree, vegetables
Thing, it can effectively prevent and treat scab, anthrachose of grape, white rot, spot defoliation, powdery mildew, brown spot, rust, stripe rust, head blight
Deng.We have found that diethyl aminoethyl hexanoate and Difenoconazole, which are used in combination, has certain preventive effect to tobacco weather-fleck, purslane carries
Take thing and HUICAI extract to improve the prevention effect of diethyl aminoethyl hexanoate and Difenoconazole to tobacco weather-fleck, but can drop simultaneously
Chlorophyll content in low tobacco leaf.By using the mixed solvent of special ratios to purslane extract and HUICAI extract
Dissolved, while adjust purslane extract, HUICAI extract mixed solution and diethyl aminoethyl hexanoate, Difenoconazole mixed solution
Addition sequence, can solve the problems, such as that tobacco leaf Determination of Chlorophyll content is relatively low.
The advantage of the invention is that：It is preferable to the prevention effect of tobacco weather-fleck, the incidence of disease and disease can be significantly reduced
Feelings index, while the chlorophyll content in tobacco leaf can be improved.

Test example：Proving ground is located at Jiangxi Province Yuean County Dai Fang towns village of Zhushan County, and the ground occurs more tight toward year-climate spot disease
Weight.Experiment uses RANDOMIZED BLOCK DESIGN, if totally 6 processing of 5 experimental groups and 1 clear water control group, each handle 3 repetitions.
Each cell plants the row of cigarette 2, often 30 plants of row, 60 plants, the ㎡ of the cell gross area 1400 is closed per cell, experimental plot surrounding sets protection row.5
Individual experimental group gives anti-tobacco weather-fleck combination agent made from embodiment 1-5 respectively, is K326 for examination tobacco bred.
Each processing dispenser in three times, first time dispenser are being transplanted latter week, and second of dispenser at the initial stage of a disease, is fallen ill one week
Third time dispenser is carried out afterwards.Each dispenser determines liquid dose according to the size of cigarette strain, it is ensured that every leaf of cigarette strain can
It is enough to be covered by decoction.The 7th day after the third time dispenser incidence of disease for investigating each cell whole cigarette strain weather spot disease and each cell
Disease index.In the maturity period with the 10th leaf in the middle part of SPAD-502 Chlorophyll meters measure cigarette strain and from the 2nd leaf of top number
The chlorophyll relative content of leaf central part.It the results are shown in Table 1 and table 2.
Severity Scaling standard:
0 grade:It is disease-free;
1 grade:Lesion area accounts for the blade gross area below 3%；
2 grades:Lesion area accounts for blade gross area 3-10%；
3 grades:Lesion area accounts for blade gross area 11-25%；
