Problems solved by technology

[0003] The use of plant protective agents has a positive effect on the control of pests. Its purpose is to improve the quality and yield while giving full play to the potential and role of existing agricultural chemicals to effectively prevent and control pests and diseases, so as to reduce the amount of pesticides and pesticide residues. However, in the specific use process, it is found that the plant protection agents of the prior art have different effects on plants. For example, the components of some plant protection agents can inhibit plant growth, and some cannot be compared with other plant protection agents. Problems with application of agricultural chemicals together
[0004] In addition, the plant protection agents in the prior art focus on the efficacy of plant disease and insect pest control. The chemical plant protection agents mainly use chemical agents, which have a strong ability to kill insects, but are less environmentally friendly. At the same time of pest control, its components entering the ecological environment will affect the stable development of the ecological environment

Abstract

The invention relates to the technical field of plant protection, in particular to a plant protective agent as well as a preparation method and application thereof. The plant protective agent is prepared from the following raw materials in percentage by weight: 60-70% of carboxymethyl chitosan; 5-10% of polyethylene glycol; 10-20% of a deinsectization and sterilization material; 3-8% of a moisturizing material; 2-4% of an emulsifier; 0% or 3-6% of asphalt; and 0% or 1-3% of a surfactant. The deinsectization and sterilization material is prepared from the following raw materials in parts by weight: 15-20 parts of tobacco leaf waste; 5-10 parts of folium artemisiae argyi; 5-10 parts of pericarpium citri reticulatae; 35-50 parts of radix sophorae flavescentis; 25-40 parts of cortex meliae; 10-15 parts of derris trifoliata; 10-20 parts of cinnamic acid; and 10-20 parts of phenyllactic acid. The plant protective agent is environment-friendly, can inhibit plant diseases and insect pests, and can promote plant growth, and the plant protective agent can be applied together with agricultural chemicals.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a plant protection agent and its preparation method and application. Background technique [0002] At the same time as economic development, the accompanying environmental pollution problems are becoming more and more serious. At present, my country is vigorously carrying out ecological environment construction and environmental pollution control, with the purpose of providing a good environment for economic development. In environmental governance and environmental pollution control, plants play a very important role, but under the influence of the expansion of the use of pesticides, chemical fertilizers, and pesticides, environmental pollution is a practical problem in agricultural production. Therefore, agricultural It is the theme of agricultural development in the 21st century to unify the development and protection of the environment and realize the sustainable dev...
