Abstract

The invention relates to a pesticide composition for preventing and treating plant virus diseases, a preparation method and application thereof, and belongs to the field of pesticide preparation. The pesticide composition for preventing and treating plant virus diseases is composed of active ingredients and auxiliary materials: the active ingredient includes Radix isatidis extract and mannan peptide; wherein, Radix isatidis extract is obtained by extracting Radix isatidis with water or an organic solvent. In the present invention, the Radix isatidis extract and mannan peptide are compounded and used to prevent and treat plant virus diseases, with quick onset, high control effect, long duration, non-toxicity and no residue, and at the same time, it can also improve the yield and quality of plants. quality.

Description

technical field [0001] The invention relates to a pesticide composition for preventing and treating plant virus diseases, a preparation method and application thereof, and belongs to the field of pesticide preparation. Background technique [0002] Plant virus disease is a major hazard in agricultural production, known as "plant cancer". There are more than 1,000 common plant virus diseases, most of which are caused by 716 viruses, and the damage is second only to fungi. Plant viruses can infect a wide variety of crops, such as grain, oilseeds, fruit trees, vegetables, Chinese medicinal materials, flowers, etc. [0003] At present, the prevention and control of plant virus diseases are mainly the following two ways: For the prevention and control of virus diseases in field production, the spread of viruses is generally controlled by means of pest control and disease prevention, strengthening field management, plant quarantine, and isolation of infected plants. Once infeste...
