A using method of the compound chemical for preventing and curing the peanut leaf spot disease comprises the following steps of: 1) using water to dilute the compound chemical by 500-600 times according to a mass ratio; and 2) spraying the diluted solution onto the leaf surfaces of peanuts for 2-3 times at an interval of 10-15 days, with the dosage of the compound chemical per time being 50-80g/mu. The compound chemical for preventing and curing the peanut leaf spot disease and the using method thereof have the beneficial effects that: 1) germs can be effectively killed and the goal of preventing and curing the peanut leaf spot disease is achieved; and 2) the nutritious effect is obtained and the disease resistance of peanut leaves can be improved.
Description
Technical field
The present invention relates to a kind of medicament of preventing and treating leaf spot of peanut, particularly a kind of compound of preventing and treating leaf spot of peanut.
Background technology
Peanut is one of oil crops of extensively cultivating in the world, is also one of important oil crops of China, and peanut nutrition is abundant, and economic worth is high, strong adaptability, production cost is low, and vast farmers has higher plantation enthusiasm, therefore, peanut is large in China's cultivated area, widely distributed.
At present, leaf spot of peanut mainly is divided into black spot, brown spot, focal spot disease and net blotch, and what China occurred in the past is mainly black spot and brown spot, but in recent years, focal spot is sick and net blotch is popular very fast, becomes the Major Diseases of harm Folium Arachidis hypogaeae section.Peanut is subject to after being ill, causes leaf, stem early withered, and large quantities of fallen leaves, have a strong impact on the pod plumpness, the lighter's underproduction 4%～10%, and severe one reaches more than 30%.The cercospora brown spot of peanut emergence period early, occurs at initial bloom stage; Black spot is slower, in the lower pin phase, just occurs.Therefore, brown spot is more in lower blade, and black spot is many, and in upper blade, the autumn peanut is more outstanding with black spot, and Spring Peanut is more general with brown spot.Two diseases all can endanger blade, petiole, stem, ovary, handle and pod shell, cause fallen leaves when serious, and plant is early withered, affects nutrient accumulation and cause pod not enrich, reduction kernel percent and oleaginousness, easy shedding and seed germination during results.The major cause of peanut generation leaf spot, with a little less than short, hot and humid environment of the period of crop-rotation, variety resistance, the sandy soil soil fertility is poor, fertilising is not enough etc. that close relationship is arranged.
At present, the main method of preventing and treating of leaf spot of peanut has three kinds:
The first is for transferring to the change of crops, and the host of leaf spot of peanut bacterium is more single, an infecting peanut, adopt the shift of crops such as peanut and wheat, sweet potato, millet, making germ can not get suitable host, can reduce harm, effectively control the generation of disease. the crop rotation more than 2 years is preferably carried out on sick ground.
The second is for strengthening cultivation management: large plough deep ploughing, to begin sowing in good time, and rational close planting, use sufficient base fertilizer, promotes the healthy and strong growth of peanut, improves disease resistance; Remove in time the invalid body of leaving over field after results, nonvoluntary unrest is thrown, is huddled; Turning in time in sick ground, eliminates and infect source.But present method can only be delayed the harm of light leaf spot of peanut, can not eradicate.
The third is chemical control, and prevention effect medicament preferably has Bordeaux mixture (copper sulfate, lime and water form than proportioning according to the quality of 1: 1: 200), 400 times of liquid of 80% Zineb wettable powder, 300 times of liquid of 80% zinc manganese ethylenebisdithiocarbamate.Chemical control has certain effect, but nutrition can not be provided.
Summary of the invention
The problem to be solved in the present invention is: a kind of compound and the using method that can treat leaf spot of peanut is provided, and this medicament also has the effect of nutrition Folium Arachidis hypogaeae simultaneously.
In order to solve the problems of the technologies described above, the compound of preventing and treating leaf spot of peanut of the present invention comprises the following component by the ratio of quality and the number of copies preparation:
The compound of preventing and treating leaf spot of peanut of the present invention, the scheme after further optimizing is to comprise the following component by the ratio of quality and the number of copies preparation:
The compound of preventing and treating leaf spot of peanut of the present invention, the scheme after further optimizing is to comprise the following component by the ratio of quality and the number of copies preparation:
In addition, the present invention also provides a kind of using method of preventing and treating the compound of leaf spot of peanut, comprises following concrete steps:
The first step, the compound that water will be prevented and treated leaf spot of peanut dilutes 500-600 doubly in mass ratio;
Second step, the foliage spray by the liquid after dilution at peanut, sprayed once every 10-15 days, and spraying number of times is 2-3 time, and the consumption that at every turn sprays compound used is 50-80 g/acre.
The beneficial effect that the present invention obtains is: (1) thiophanate and derosal have the ability of good killing pathogenic bacteria, thereby the effective killing pathogenic bacteria of energy, reach the purpose of preventing and treating leaf spot of peanut; (2) urea, potassium primary phosphate, vitriolate of tartar, boric acid and NaFeEDTA have trophism, therefore can strengthen the resistance against diseases of Folium Arachidis hypogaeae.
Embodiment
Embodiment 1
The NaFeEDTA of the boric acid of the vitriolate of tartar of the potassium primary phosphate of the urea of 50% carbendazol wettable powder of 50% thiophanate wettable powder of 175 grams, 165 grams, 120 grams, 125 grams, 125 grams, 75 grams and 40 grams is mixed, make 725 gram compounds.
