Abstract

The invention discloses a disease resistant drug for greenhouse cucumber plantation. The drug comprises, by weight, 10-15 parts of a 72% cymoxanilmancozeb wettable pulvis, 8-12 parts of honeysuckle flower, 3-6 parts of Achyranthes aspera, 3-6 parts of a substance named Shuangbeier, 6-9 parts of clove oil and 2-4 parts of chlorothalonil. The drug has the advantages of simple burdening, use convenience, and good cucumber downy mildew treatment effect. When the drug is used, the 72% cymoxanilmancozeb wettable pulvis, the honeysuckle flower, the Achyranthes aspera, the substance named Shuangbeier, the clove oil and the chlorothalonil are mixed to prepare a liquid having a mass 400-500 times the total amount of the above raw materials, and the liquid is sprinkled, wherein when the honeysuckle flower and the Achyranthes aspera are used, the honeysuckle flower and the Achyranthes aspera are subjected to alcohol extraction to obtain extract liquids, and the extract liquids are used when the honeysuckle flower Achyranthes aspera are mixed. A result of tests show that the liquid having a mass 400-500 times the mass of the above obtained mixture has an obvious inactivation effect on Pseudoperonospora cubensis Rostov., and has a good sterilization effect.

Description

The disease-resistant medicine of a kind of greenhouse gardening cucumber

 

Technical field:

The present invention relates to vegetables medicine, particularly the disease-resistant medicine of a kind of greenhouse gardening cucumber.

 

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 proportioning simple, easy to use, the effective disease-resistant medicine of a kind of greenhouse gardening cucumber 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 proportioning simple, easy to use, the effective disease-resistant medicine of a kind of greenhouse gardening cucumber for the treatment of cucumber downy mildew.

To achieve these goals, the invention provides the disease-resistant medicine of a kind of greenhouse gardening cucumber, wherein, comprise the component of following unit of weight:
