Cruciferous vegetable soft rot disease control method

Abstract

The invention provides a Cruciferous vegetable soft rot disease control method comprising the following steps: 1, ecology treatment: applying difulai fertilizer; 2, agriculture control: planting anti-disease breed, crop rotation for more than 2 years, plowing soil and drying ridges before plantation, and sowing in a proper period; 2, biotic control: controlling field weeds and pest quantity; 4, biological control: applying a compound preparation to pour root in a disease initial stage, wherein the compound preparation is formed by the following elements by weight parts: 40-50 parts of streptomycin, 0.1-0.5 parts of chitosan, 5-10 parts of propyl kresoxim methyl, 10-15 parts of garlic extract, 10-15 parts of mycin, and 5-10 parts of Oxolinic acid; 5, physical control: removing bacterium sources; 6, chemical control: applying saurat-bismerthiazol spray at the disease initial stage. The method selects anti-disease breeds, enhances cultivation management, combines pest control and physical control, uses the compound preparation to control the soft rot disease, so the plants can hardly generate drug resistance, thus preventing soft rot disease Cruciferous vegetable.

Description

technical field [0001] The invention relates to a planting technology of cruciferous vegetables, in particular to a method for preventing and treating soft rot of cruciferous vegetables. Background technique [0002] Cruciferous vegetables include cabbage, cabbage, kale, mustard greens, radishes and other plants, among which soft rot is a common disease of cruciferous vegetables, and its pathogen is Erwinia carotovora subsp.carotovora (Jones) Bergey et al.], Bacteria, Erwinia spp. Soft rot pathogens mainly overwinter in diseased plants and diseased tissues. The primary infection source of soft rot disease in cruciferous vegetable fields is mainly the diseased residues near the vegetable cellar, the soil and compost of the diseased residues, and the overwintering plants with bacteria. Vector insects and other host plants in the field, etc. The pathogen is mainly transmitted by insects, rainwater and irrigation water, and invades the host from wounds. [0003] The preventio...

Problems solved by technology

Streptomycin is the mainstream of the existing preventive and control drugs, which is relatively simple and will produce drug resistance after use, which is not conducive to the suppression of soft rot
