Abstract

The invention discloses a composition for controlling phytophthora root rot of oncidium. The active pharmaceutical ingredients of the composition consist of mandipropamid, cymoxanil and methyl disulfide according to the weight ratio of 1:(5-10):(0.1-0.5). The composition has a favorable control effect on phytophthora root rot of oncidium.

Description

technical field [0001] The invention relates to a composition for preventing and treating oncidium phytophthora. Background technique [0002] Oncidium, also known as Dancing Orchid, Dancing Girl Orchid, King Phalaenopsis, Tubal Orchid, etc., has 1 to 3 leaves, the plant is light and slow, the flower stems are light and drooping, and the flowers are strange and lovely. [0003] Oncidium Phytophthora can occur all year round, but in the rainy season, the oncidium is the most serious when the watering is too wet or the ventilation is poor, especially the young seedlings that have just come out of the bottle are the most vulnerable. Infected parts produce brown lesions, which expand rapidly under high temperature and humidity, and eventually turn into dark brown spots, and deciduous stems rot until the plants die. Contents of the invention [0004] The technical problem to be solved by the invention is to overcome the existing defects and provide a composition for preventing...
