Use method of drugs for preventing and treating cladosporium cucumerinum

Abstract

The invention discloses a use method of drugs for preventing and treating cladosporium cucumerinum. The use method comprises the following steps: A, preparing a raw solution which comprises the following raw materials: 50% of carbendazim, 70% of thiophanate methyl, a new high lipid membrane, a fruit and vegetable base promoter, astragalus polysaccharides, glycyrrhizic acid, radix isatidis and fructus forsythia; B, soaking tomato seeds subjected to greenhouse culture in warm water at the temperature of 55 DEG C for 30 minutes to remove pathogenic bacteria inside and outside the seeds, taking out, cooling in cold water, soaking in the raw solution with the volume being 400 times that of the seeds for 1.5-2 hours, taking out, washing by clear water, drying in the sun, accelerating germination, and seeding; C, during an attack, adding water into the raw solution for diluting the raw solution by 600 times, and spraying; D, while spraying in the step C, adding water into the raw solution for diluting the raw solution by 500 times, and carrying out root irrigation. The use method is simple; the used drugs are simple in ratio, convenient to use and good in treatment effect on tomato leaf mould; a test shows that a mixture diluted by 400-600 times has a remarkable deactivation effect on deuteromycotina-cladosporium fulvum and has a good sterilization effect.

Description

[0001] Technical field:

[0002] The invention relates to a medicine for vegetables, in particular to a method for using a medicine for preventing and controlling leaf mold fungus.

[0003] Background technique:

[0004] Leaf mold is also known as erythema. Tomato leaf mold is a common and serious disease of greenhouse tomatoes. It often causes early withering of leaves and early seedling pulling. Leaf mold overwinters with hyphae attached to the surface of seeds and invaded into the seed coat, as well as hyphae and spores remaining and attached to diseased residues, scaffolding and soil. In the next spring, under suitable temperature and humidity conditions, new conidia are produced, and the spores invade with the wind or ejected to the leaves and other parts, and continue until the end of autumn. The prevalence of the disease is fast, and under suitable conditions, it only takes about 10 to 15 days from the initial stage to the full stage. The relative humidity is abov...
