Plant virus immune agent and preparation method and application thereof

Abstract

The invention provides a plant virus immune agent. The plant virus immune agent is prepared from, by weight, 2%-35% of amino-oligosaccharin, 1%-15% of lentinan, 5%-20% of allicin, 5%-10% of ethyl alcohol, 5%-10% of urea, 1%-3% of ethylene diamine tetraacetic acid and the balance of a lonicera japonica and radix isatidis contained traditional Chinese herbal water solution, wherein the lonicera japonica and radix isatidis contained traditional Chinese herbal water solution is obtained by adding dried roots of 5 parts of the lonicera japonica and dried roots of 5 parts of the radix isatidis into 90 parts of water for soaking for 5 hours, heating to 90-100DEG C for 2 hours and performing cooling and filtration. The invention further provides a preparation method and application of the plant virus immune agent. By the arrangement, plant virus disease can be effectively prevented and removed by improving immunity of plants.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a plant virus disease immune agent and its preparation method and application. Background technique [0002] Plant virus disease, commonly known as plant cancer, is a disease caused by plant virus parasitism. After the virus infects the host, it not only competes with the host for the nutrients necessary for growth, but also destroys the nutrient transport of the plant, changes some metabolic balance of the host plant, inhibits the photosynthesis of the plant, makes the plant difficult to grow, and produces deformity Symptoms such as yellowing and yellowing can seriously cause the death of the host plant. In most parts of our country, plant virus diseases on most crops have become intractable diseases, which have brought huge losses to the yield and quality of agricultural products in our country, and it is very difficult to prevent and control them. [0003] At present, the plant vi...

Problems solved by technology

In most parts of our country, plant virus diseases on most crops have become intractable diseases, which have brought huge losses to the yield and quality of agricultural products in our country, and it is very difficult to prevent and control them.

[0003] At present, the plant virus disease agents on the market, such as morpholine hydrochloride, copper preparations, etc., cannot effectively prevent and control plant virus diseases, and most of the plant virus disease agents contain a large amount of hormone agents, and the duration of effect is very short, making plant virus diseases Very easy to relapse and infection after application
