Abstract

The invention discloses a composition for controlling phytophthora root rot of cymbidium faberi rolfe. The active pharmaceutical ingredients of the composition consist of metalaxyl-M, cyazofamid and ally isothiocyanate 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 cymbidium faberi rolfe.

Description

technical field [0001] The invention relates to a composition for preventing and treating cymbidium phytophthora. Background technique [0002] Cymbidium (scientific name: Cymbidium faberi Rolfe): It is a ground herbaceous plant of the genus Cymbidium in the family Orchidaceae. Pseudobulbs are inconspicuous, clustered into clumps, and oval in shape. The leaves are belt-shaped, strong upright, the veins are translucent, and the edges are often coarsely serrated. The flowers are often light yellow-green, with purplish-red spots on the lips, and there are many flowers on one stem. Capsule nearly narrowly elliptic, 5-5.5 cm long and 2 cm wide. The flowering period is from March to May. [0003] Phytophthora can occur throughout the year, but in the rainy season, the disease 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 les...
