Problems solved by technology

At present, most antiviral agents on the market are chemical pesticides, and there are pesticide residues in spraying, which cannot meet the requirements of green agriculture and sustainable development
[0003] Coriolus versicolor glucan is a substance with excellent antiviral effect discovered in recent years. However, for its preparation, it is especially suitable to use specific auxiliary agents (dispersant, wetting agent) to make water-dispersible granules with excellent performance. agent, there is no report

Abstract

The invention relates to coriolus versicolor glucan water dispersible granules as well as a preparation method and application thereof. The water dispersible granules contain the following components in percentage by weight: 1-70% of coriolus versicolor glucan raw medicine, 0.1-4.0% of wetter, 0.1-8.0% of dispersant, 0.1-2.0% of adhesive, 0.1-8.0% of disintegrant and fillers which are complemented to achieve 100%, wherein the wetter is GEROPONL-WET / P; the dispersant is GEROPONT / 36. The water dispersible granules disclosed by the invention are greatly improved in the aspects of dispersibility, wetting time, suspending performance and the like because of adopting the specific dispersant and wetter.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to the field of fungicides, and in particular to a water-dispersible granule of versicolor versicolor that can effectively prevent and treat viral diseases of crops, and a preparation method and application of the water-dispersible granule. technical background [0002] Crop virus disease is a widely occurring and difficult to control disease in agricultural production, such as cucumber, tobacco, rice, watermelon, pepper virus disease and so on. The occurrence of viral diseases often causes crops to lose leaves, flowers, fruits, deformities, affect yield and quality, and even fail to harvest. At present, the methods of preventing and treating viral diseases of crops mainly include planting anti-virus varieties, strengthening field management, and spraying anti-virus agents. However, due to the variety of ways and fast transmission speed of viruses in the field, viral diseases will develop...
