Composition for preventing and treating downy mildew of chicory and preparation method of composition

Abstract

The invention relates to the field of pesticides, in particular to a composition for preventing and treating downy mildew of chicory. The composition is prepared from the following raw materials in parts by weight: 8 to 12 parts of fructus corni, 12 to 18 parts of myrrh, 12 to 18 parts of caulis sargentodoxae, 3 to 8 parts of sargassum, 12 to 18 parts of Japanese thistle herb or root, 2 to 6 partsof radix rubiae, 12 to 18 parts of herba geranii wilfordii, 3 to 8 parts of flos genkwae, 10 to 20 parts of folium eriobotryae, 12 to 18 parts of cortex pericarpii granati, 8 to 12 parts of herba patriniae, 8 to 12 parts of fructus rosae laevigatae, 10 to 20 parts of radix polygalae, 12 to 18 parts of compound bacteria and 10 to 20 parts of compound amino acid. The composition disclosed by the invention can prevent and treat the downy mildew of the chicory to the maximum extent; the incidence of the downy mildew of vegetable chicory is controlled at 1.26 percent and total effective rate of the downy mildew of the chicory is controlled at 95 percent or above; in addition, the composition for preventing and treating the downy mildew of the chicory has the advantages that the preventing andtreating effect is remarkable, and pathogenic bacteria are effectively inhibited and killed, so that the disoperation of the pathogenic bacteria and other pests on vegetables is reduced, the breedingof the pathogenic bacteria is effectively avoided, and further the safety of the vegetables is ensured.

Problems solved by technology

Spray once every 7 days and prevent and control 2 to 3 times in a row, which can effectively control the spread of downy mildew. However, the traditional spraying of pesticides will cause drug residues, which will cause harm to the human body, and the effect of disease control is not obvious. Therefore, to effectively improve the control of traditional chicory downy mildew is the focus of current research
