Composition for resisting cladosporium fulvum

Abstract

The invention discloses a composition for resisting cladosporium fulvum. The composition is composed of, by weight, 10-15 parts of 35% carbendazim, 8-12 parts of 22% thiophanate methyl, 10-15 parts of lignin, 4-8 parts of monopotassium phosphate, 4-8 parts of 3% chitosan solution, 6-10 parts of glycyrrhizic acid, 4-8 parts of radix isatidisand and 6-10 parts of fistular onion stalk juice. The composition is simple in ratio, convenient to use and good in cladosporium fulvum resisting effect; through experiments and tests, 400-fold to 600-fold solutions of the mixture have a remarkable inactivating effect on the eubacterium deuteromycotina cladosporium fulvum and are good in sterilizing effect.

Description

Technical field: [0001] The invention relates to vegetable medicines, in particular to an anti-Xanthosporium composition. Background technique: [0002] Leaf mold mainly infects tomato plants in the greenhouse. It is a fungus belonging to the subphylum Deuteromycotina, and its fungus is named as Xanthosporium. 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 above 80%, which is conducive to the formation of spores and the expansion of lesions. When ...
