Problems solved by technology

As far as these control measures are concerned, the use of new anti-virus varieties or sterile seedlings can completely solve the problem of virus carried by potato seedlings, but it cannot solve the infection virus that already exists in the planting environment and will exist for a long time; In the prevention and treatment of viral infections with drugs, in addition to the control effect, comprehensive issues such as the safety of the drug itself, the convenience of use, and the cost of use must also be considered. Therefore, as far as the control of sweet potato virus diseases is concerned, there is still a lot of research and development work to be done. further refinement and improvement

specific Embodiment

[0030] The present invention will be further explained below in conjunction with the examples. Before introducing the specific examples, a brief introduction of some experimental backgrounds in the following examples is given below.

[0031] Experimental reagents:

[0032] Propazole·morpholine: product of Daoyuan Biological Co., Ltd. (18% propazole·morpholine wettable powder, this product has high efficiency, low toxicity, systemic broad-spectrum virus inhibitor, when used, two Each of the two active ingredients has a strong mode of action and biological activity, and when the two active ingredients are used in combination, the quick-acting and long-lasting effects of botanical pesticides can be enhanced);

[0033] Zinc sulfate, potassium dihydrogen phosphate, products of Zhengzhou Danong Pharmaceutical Co., Ltd.;

[0034] Bacillus subtilis, a product of Yunnan Xingyao Biological Products Co., Ltd. (this product is a wettable powder, with a content of Bacillus subtilis of 1 b...

Embodiment 1

[0041] In this example, the 19 varieties of commercial potato were taken as an example. In March 2016, a planting test was carried out in a village field in Xiangcheng County, Xuchang City (before planting, sweet potatoes had been continuously planted in this plot for 2 years, and there was a slight sweet potato virus disease. exists), and the relevant experimental conditions are briefly introduced as follows.

[0042] (1) Treat the cultivation soil, specifically: spread quicklime on the soil surface at a rate of 15Kg / mu, then deeply plow the soil by about 30cm, and dry the ground for about 4 days;

[0043] (2) Seedlings and ridges, specifically, ridges when transplanting seedlings, between ridges: row spacing 50cm, plant spacing 30cm, ridge height 20cm;

[0044] (3) Post-management, specifically:

[0045] One-time fertilization at the seedling pressing stage, using a certain brand of compound fertilizer 10kg / mu (the effective nutrient content of nitrogen, phosphorus, and pot...

Embodiment 2

[0052] In this example, Qinshu 5 varieties were taken as an example. In March 2016, a planting test was carried out in a village in Yancheng District, Luohe City (before planting, sweet potatoes had been continuously planted in this plot for 2 years, and there was a slight sweet potato virus disease). , the relevant experimental conditions are briefly introduced as follows.

[0053] (1) Treat the cultivation soil, specifically: spread quicklime on the surface of the soil according to the ratio of 20Kg / mu, then deeply plow the soil about 50cm, and dry the ground for about 5 days;

[0054] (2) Seedlings and ridges, specifically, ridges when inserting seedlings, between ridges: row spacing 90cm, plant spacing 80cm, ridge height 35cm;

[0055] (3) Post-management, specifically:

[0056] One-time fertilization at the seedling pressing stage, using a certain brand of compound fertilizer 35kg / mu (the effective nutrient content of nitrogen, phosphorus, and potassium in the compound f...

Abstract

The invention belongs to the technical field of control of plant virus diseases, and concretely relates to a composition for preventing and controlling a sweet potato virus disease. The composition isprepared from 40 to 50g of biological product containing active bacillus subtilis, and 30 to 50g of propiconazole.moroxydine, wherein the biological product containing the active bacillus subtilis isa biological product adsorbing the active bacillus subtilis, and the required activity number of the bacillus subtilis in the biological product is 8 to 10 hundred million / g. By adopting the composition for preventing and controlling the sweet potato virus disease, and a cultivation method of the composition for preventing and controlling the sweet potato virus disease provided by the invention,a preliminary experiment result shows that sweet potato leaves are plump and dark green, a root system is developed, the later-period maturing is slow, potato tubers are big, a root tuber is thick andshort in shape in order, the skin color is bright, the taste is good, the surface is smooth, and the storage endurance is good; compared with a control group, the virus disease morbidity can be reduced by 70 to 80 percent, the yield can be improved by 40 to 60 percent, and a better production increase and income increase effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of prevention and treatment of plant virus diseases, and in particular relates to a composition for prevention and treatment of sweet potato virus diseases. Background technique [0002] Sweet potato has the characteristics of strong stress resistance, high yield, and wide application. Whether it is used as a common food or as an energy crop for ethanol production, it has great application value. In sweet potato planting, sweet potato virus disease is the most serious disease in its production and planting. Once infected, the infected plants will have serious seed degradation, and the yield will be significantly lower after the infected potato seedlings are inserted in the field. Low, the reduction rate can reach more than 60%. [0003] Sweet potato virus disease mainly has the following types of symptoms: [0004] (1) Leaf spot type, which can occur at seedling stage and field stage. In the early stage of...
