Abstract

The invention discloses an application method of a combination for treating anthracnose, comprising the following steps: A, a stock solution is prepared: the stock solution is a mixture of zingerone, astragalus polysaccharide, baicalein, 38% oxadixyl azoxystrobin, Centella asiatica, duckweed and 20% imazalil water-emulsion mixture; B, water is added into the stock solution to prepare a diluent which accounts for 400-800 times the mass of the stock solution; C, use dosage per mu is 4-4.5kg; the medicine is sprayed uniformly; front and back sides of a leaf are sprayed uniformly; the key point is to spray the eggplant; and spraying is carried out at 4-5 pm on sunny days; and D, as for weak eggplants, a leaf fertilizer is sprayed to make plants strong and enhance disease resistance; and during fertilization, a nitrogenous fertilizer is minimized or not used, and contents of a phosphate fertilizer and a potash fertilizer are raised. The method provided by the invention requires a simple ratio, is convenient to use, and has a good effect of treating eggplant anthracnose.

Description

The using method of the compound for the treatment of anthracnose

 

Technical field:

The present invention relates to vegetables medicine, particularly a kind of using method for the treatment of the compound of anthracnose.

 

Background technology:

The sick fruit eggplant anthracnose main harm fruit of eggplant anthracnose harm, fruit morbidity, produces subcircular, ellipse or irregular shape at fruit surface at the beginning, pitchy, the slightly scab of depression.Scab constantly expands, or scab converges and can form large-scale scab, sometimes extends to fruit half.The later stage disease portion close raw black point in surface, overflows the red mucilage of germanium when moist.The micro-brown that is of pulp that disease portion is subcutaneous, dry rot shape, can cause whole fruit rot when serious.Its pathogenic germ survives the winter with invalid body with mycelium and aceravlus in soil, also can conidium be attached to the surface of the seed and survives the winter.Produce conidium by the aceravlus of surviving the winter next year, borrows rainwater sputter to be transmitted on the fruit of plant bottom and cause morbidity, and the infected seed of sowing just can infect seedling while sprouting makes it morbidity.After fruit morbidity, sick portion produces a large amount of conidiums, and anthropochory when borrowing wind, rain, insect transmission or plucking fruit, infects repeatedly again.Under warm high humidity environment, be easy to morbidity, disease is many in generation in 7～August and popular.Plant closing, pluck not in time, hypsography low-lying, and excess surface water after rain, when nitrogenous fertilizer is too much, morbidity is heavy.The present invention is based on prior art, aim to provide a kind of proportioning simple, easy to use, the using method of the compound for the treatment of treatment anthracnose.

 

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 using method of the compound for the treatment of treatment anthracnose.

To achieve these goals, the invention provides the using method of the compound for the treatment of anthracnose, wherein, step is as follows:

A, preparation stoste: the component of stoste is zingerone, astragalus polyose, baicalein, 38% Evil frost bacterium ester, centella, duckweed, the mixture of 20% imazalil aqueous emulsion

B, stoste add water and allocate to the dilution of 400-800 quality multiple ratio;

C, per hectare mu consumption 4-4.5kg, it is evenly thoughtful that spray is wanted during medicine, and leaf is just, the back side evenly sprays, and emphasis is eggplant fruit, the 4-5 point in afternoon that spraying time is sunny weather;

D, for the frail eggplant of plant, spray foliage fertilizer and carry out strong plant, to increase resistance against diseases, meanwhile, during fertilising, reduce or without nitrogenous fertilizer, improve the content of phosphorus and potash fertilizer.

The compound of the treatment anthracnose of using through using method of the present invention, wherein, comprises the component of following unit of weight:

Zingerone 5-10 part, astragalus polyose 2-4 part, baicalein 2-4 part, 38% Evil frost bacterium ester 2-4 part, centella 4-6 part, duckweed 6-8 part, 20% imazalil aqueous emulsion 3-5 part.

Or, comprise the component of following unit of weight:

Zingerone 5-8 part, astragalus polyose 2-3 part, baicalein 2-3 part, 38% Evil frost bacterium ester 2-3 part, centella 4-5 part, duckweed 6-7 part, 20% imazalil aqueous emulsion 3-4 part.

Or, comprise the component of following unit of weight:

Zingerone 8-10 part, astragalus polyose 3-4 part, baicalein 3-4 part, 38% Evil frost bacterium ester 3-4 part, centella 5-6 part, duckweed 7-8 part, 20% imazalil aqueous emulsion 4-5 part.

 

During use, after said components is mixed, be configured to 400-800 times of liquid of quality multiple, carry out spraying operation.The unit of percentage sign is mass percent.

 

Advantage of the present invention is that proportioning is simple, easy to use, treats the effective of eggplant anthracnose, is specially:

When the present invention uses, zingerone, astragalus polyose, baicalein, 38% Evil frost bacterium ester, centella, duckweed, 20% imazalil aqueous emulsion.Mix compositely, after having mixed, add clear water to be configured to 400-800 times of liquid, carry out spraying operation, (when centella and duckweed are used, use alcohol leach extraction method to extract extract, what during mixing, use is extract.) through experimental test, the 400-800 of mixture times liquid, good to Deuteromycotina Colletotrichum fungi bactericidal effect, average effectiveness level 92.1%.
