Abstract

The invention discloses a use method of a drug for treating cucumber downy mildew. The use method includes the steps: A, preparing stock solution; B, adding water into the stock solution and mixing the stock solution and the water into dilution solution with 400-500 mass times; C, uniformly and thoroughly spraying the dilution solution to the front and the back of each leaf, focally spraying the dilution solution to back mildew layers of the diseased leaves and protecting upper healthy leaves by spraying; D, maintaining the temperature in a greenhouse at 33-34 DEG C after spraying. The stock solution comprises 30% of oxadixyl, polygonum cuspidatum, fresh ginger, cream bell, cinnamyl aldehyde and azoxystrobin. 3-3.75kg of dilution solution is used per hectare. After the drug is sprayed for three days, the temperature in the greenhouse is not lower than 16 DEG C at night and not lower than 10 DEG C in the early morning, ventilation and moisture removal are performed, and the air humidity in the greenhouse is reduced, so that environmental conditions are adverse to forming, germinating and disseminating sporangia of the cucumber downy mildew. The use method is simple, the used drug is simple to match and convenient to use, and the effect of treating the cucumber downy mildew is fine.

Description

A kind of using method for the treatment of the medicine of dry cucumber leaf

 

Technical field:

The present invention relates to vegetables medicine, particularly a kind of using method for the treatment of the medicine of dry cucumber leaf.

 

Background technology:

The morbidity of cucumber downy mildew Seedling Stage, the irregular chlorisis yellowish-brown spot of the positive generation of cotyledon, the straight cucumber downy mildew of scab footpath 0.2-0.5 centimetre, when moist, the scab back side produces taupe mustiness thing, and when serious, cotyledons turn yellow is withered.Strain morbidity, how, from forward position, greenhouse, there is water stain shape, light green fleck in morbidity strain before this middle and lower part blade reverse side, and front is aobvious, and rear scab expands gradually, front exposed, scab flavescence brown, is limited by vein, and scab is polygonal.Under wet condition, there is puce or the sparse mould layer of taupe in the scab back side.When serious, scab joins together, and blade is withered.Downy mildew is modal a kind of disease on cucumber, and seedling stage, strain phase all can catch an illness.Conventionally first by plant middle part blade, start morbidity,, there is chlorisis spot in portion's expansion up and down gradually on their early stage blade, forms the irregular shape scab of yellowish-brown after expansion.When humidity is high, vacuum side of blade is first water soaking mode, then produces the mould layer of grey black.Necrosis place of blade back scab can be oozed out colourless or light yellow droplet.Scab is expanded very soon, and l～2 its expansion of day internal cause is subject to vein restriction and is polygonal, and especially the most obvious with the water soaking mode horn shape scab in morning, live in retirement noon a little.In the later stage, scab and near mesophyll are rust.When seriously ill, blade is covered with scab, mutually in flakes, causes leaf margin curling withered, and last blade is withered and yellow.Slowly, scab is less for the expansion of disease-resistant variety blade chlorisis spot, is polygonal even circular, and the mould layer in the scab back side is sparse or there is no mould layer.Its pathogen claims Cuba artificial downy mildew, belongs to Mastigomycotina fungi.Sporangiophore stretches out from pore, single raw or 2～4 Shu Sheng, and colourless, base portion slightly expands, and top is acute angle branch 3～5 times, and branch end a raw sporangium, the avette or lemon shape of sporangium, top tool papilla, filbert, unit cell.For being bacterial parasite, only can be parasitic on life plant, there is Differentiation of Pathogenicity phenomenon.Between China's bacterial strain of cucumber downy mildew bacteria, there is pathogenic strong and weak difference, but not yet clearly distinguish biological strain.The present invention is based on prior art, aim to provide a kind of manufacture method simple, the product proportioning of use is simple, easy to use, effective a kind of using method for the treatment of the medicine of dry cucumber leaf for the treatment of cucumber downy mildew.

Summary of the invention:

The object of the invention is to overcome the shortcoming existing in prior art, provide a kind of manufacture method simple, the product proportioning of use is simple, easy to use, effective a kind of using method for the treatment of the medicine of dry cucumber leaf for the treatment of cucumber downy mildew.

To achieve these goals, the invention provides a kind of using method for the treatment of the medicine of dry cucumber leaf, wherein, comprise the steps:

A, preparation stoste: the component of stoste is 30% Wakil, giant knotweed, ginger, white Bel, cinnamic acid, phonetic copper bacterium ester;

B, stoste add water and allocate to the dilution of 400-500 quality multiple ratio;

C, per hectare mu consumption 3～3.75kg, it is evenly thoughtful that spray is wanted during medicine, and leaf is just, the back side evenly sprays, and emphasis is the mould layer of the blade back of disease leaf, and top healthy leaves is sprayed to medicine protection;

D, maintain temperature of shed at 33--34 ℃ after spraying, after three days, control room temperature night and be not less than 16 ℃, indoor temperature was not less than 10 ℃ and was limited early morning, ventilation dewetting, reduces indoor air humidity, makes environmental condition be unfavorable for the sporangial formation of cucumber downy mildew and sprout and contaminate.

The medicine of the treatment dry cucumber leaf using through using method of the present invention, wherein, comprises the component of following unit of weight:

30% Wakil 10-15 part, giant knotweed 8-12 part, ginger 3-6 part, white Bel 3-6 part, cinnamic acid 6-9 part, phonetic copper bacterium ester 2-4 part.

Or, comprise the component of following unit of weight:

30% Wakil 10-12 part, giant knotweed 8-10 part, ginger 3-5 part, white Bel 3-5 part, cinnamic acid 6-8 part, phonetic copper bacterium ester 2-3 part.

Or, comprise the component of following unit of weight:

30% Wakil 12-15 part, giant knotweed 10-12 part, ginger 4-6 part, white Bel 4-6 part, cinnamic acid 7-9 part, phonetic copper bacterium ester 3-4 part.

During use, after said components is mixed, be configured to 400-500 times of liquid of quality multiple, carry out spraying operation.

30% Wakil is mass percent.

Advantage of the present invention is, manufacture method is simple, and the product proportioning of use is simple, easy to use, and treatment cucumber downy mildew effective is specially:

When the present invention uses, 30% Wakil, giant knotweed, ginger, white Bel, cinnamic acid, phonetic copper bacterium ester.After being mixed, be configured to 400-500 times of liquid of quality multiple, carry out spraying operation.(when giant knotweed and ginger are used, use alcohol leach extraction method to extract extract, what during mixing, use is extract.) through experimental test, the 400-500 of mixture times liquid, has obvious deactivation to Cuba artificial downy mildew, bactericidal effect is good.
