Control of Fusarium Wilt of Cymbidium
Symptomatic Fusarium wilt is a serious disease of Cymbidium. Seriously diseased plants die in a few weeks, and generally diseased plants can survive for a year or more. The aboveground symptoms of Fusarium wilt are similar to those caused by RhizoctoniasolaniKuhn, that is, the leaves turn yellow and wilt, the pseudo-bulbs become thinner and twisted, and finally lead to root rot.

Hybrid Magnolia leaf blight
The main symptoms occur on the leaves, and in severe cases, they can spread to petioles and buds. The disease spot mostly occurs at the leaf edge, the initial stage is faded green macula, watery, many disease spots are connected into pieces, the fan shape extends outward, the edge is dark brown, and the inside is grayish yellow, which can cause early defoliation. In a humid environment, black-gray grains appear on the fallen leaves. The cause of the disease is a fungal disease; the pathogen lives in the leaf bud and on the remnant of the diseased plant, and by means of airflow transmission, it can be infected directly from the stomata of the leaves with weak growth or physiological injury, and the wind speed is high.
