Radix Astragali root disease treatment agent and application thereof

Abstract

The invention discloses a Radix Astragali root disease treatment agent. The treatment agent is prepared by adding raw materials to 10 L of water and mixing the raw materials and water, and the raw materials comprise 10 ml of a cyantraniliprole seed treatment suspending agent, 10 ml of a thiamethoxam seed treatment suspending agent, 0.625 ml of a fludioxonil seed treatment suspending agent, 0.5 mlof a metalaxyl-M seed treatment suspending agent and 3.75 ml of a thiabendazole seed treatment suspending agent. The invention also provides an application of the treatment agent. The Radix Astragaliroot disease treatment agent has a good preventing and controlling effect on Radix Astragali root rot, can remarkably increase the yield of Radix Astragali and obviously improve the specification of Radix Astragali, and test in the main Radix Astragali production area in Longxi County, Dingxi City, Gansu Province for two consecutive years of 2017-2018 verifies that the treatment agent has a good effect. All above reagents used in the present invention are low-toxicity reagents, and comply with the provisions of Food Safety Law of the People's Republic of China. An application method of the treatment agent is uniform, and makes the pollution to water small.

Description

technical field [0001] The invention relates to the technical field of plant disease and insect pest control, in particular to an agent for treating astragalus root disease and an application thereof. Background technique [0002] Astragalus is widely planted in various parts of Gansu, especially in Dingxi and other places in central Gansu. Known as the "Millennium Medicine Township", "National Medicine Storehouse" and "Western Medicine Capital", Longxi County is one of the important production areas of "authentic medicinal materials" in the country. The production and supply guarantee base of pharmaceutical raw materials, Longxi Astragalus has passed the identification of the origin of the State Administration of Quality Supervision. In recent years, with the continuous development of the industrialization of traditional Chinese medicine, the planting area of ​​Astragalus membranaceus has also continued to expand, the crop rotation cycle has been shortened, and the area of...

Problems solved by technology

In recent years, through research, it has been proposed to replace high-toxic pesticides with low-toxicity and low-residue pesticides such as 15% Avi·chlorpyrifos EC root irrigation and 70% thiophanate-methyl wettable powder to prevent and control Astragalus root disease, and to promote and apply them on a large scale. But there are two problems at present: one is that the single application of these pesticides is not ideal for the control of Astragalus root disease; the other is that in production practice, the amount of these pesticides is too large, which will easily lead to excessive use of pesticides, affecting the quality of Astragalus membranaceus, and affecting consumption. pose safety hazards to the public, and pollute soil and water bodies at the same time

[0004] Today, on the one hand, the medicinal value of Astragalus is more and more widely recognized, and the demand for Astragalus continues to increase. On the other hand, the serious harm of Astragalus root disease leads to a decrease in production and a decline in the quality of Astragalus caused by excessive use of pesticides. These factors have seriously restricted the sustainable development of Astragalus industry
