Application method of composition for controlling tomato red spot disease

Abstract

The invention discloses an application method of a composition for controlling tomato red spot disease. The application method includes the steps of A, preparing materials: stock solution including 15% molybdenum ammonia acid solution, 2% polyvinyl alcohol, 6% azoxystrobin, carboxymethyl cellulose sodium, chlorogenic acid, oxalic acid, root of Angelica dahurica, and calamine powder; B, appropriately, soaking tomato seeds for greenhouse cultivation in warm water at 55 DEG C for 30 minutes so as to remove germs inside and outside the seeds, taking out the seeds, washing the seeds with fresh water, and sun-drying the seeds before forced sprouting and seeding; C, in the case of the disease occurring, adding water to dilute the stock solution to 600 times, and spraying the liquid; D, during spraying in the step C, adding water to dilute the stock solution to 500 times, and performing root irrigation. The application method is simple, a product ratio for use is simple, using is convenient, treatment of tomato leaf mold is effective, and testing shows that 400- to 600-time liquid of a mixture is effective in killing the red spot germs.

Description

Technical field: [0001] The invention relates to vegetable medicines, in particular to a method for using a composition for preventing and treating tomato red spot disease. Background technique: [0002] Erythema is a fungus belonging to the subphylum Deuteromycota, 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 the...
