There are many small spots in the leaves, gradually expanding, forming large brown spots. Black mould layer is produced locally and will break gradually. Affect the growth and ornamental of plants.
Strengthen management, maintain reasonably, and enhance the disease resistance of plants.
When the disease occurs, spray medicament for sterilization, spray 1000 times of antibacterial solution, spray evenly, and spray the whole plant to the back of the leaves.
When the growth of pitcher plants is slow and the disease resistance is reduced, all kinds of diseases will come to you. When the root rot occurred, the leaves on the ground became yellow and wilted gradually. The underground roots turn brown and rotten, and do not grow new roots for a long time.
Root rot is caused by Fusarium invasion. At the initial stage, it only begins to rot at the wound, but it will damage the whole plant gradually. Low temperature or too much water can cause the disease.
The growth temperature of pitcher plant is not lower than 24 ℃, and the environment with high temperature and foggy is more favorable for growth. In order to avoid rotten roots, peat soil, dry cow dung, rotten leaf soil and sand soil can be mixed and hung in the greenhouse, with proper shade.
Put in high temperature environment in summer, it is required to have good ventilation, and do not contain lime in the water when watering. In its growth period, pouring some cow dung water is helpful to the root growth.
In the early stage of the disease, the medicine should be sprayed in time. Select likujing, rootfuling, Duofu and zinc, dilute them into solution with clear water and spray them.
The scale insects were killed by spraying with 40% dimethoate emulsion 2000 times.
Pitcher is a tropical plant, which is easy to frostbite when the temperature is low. There are many small plaques in the upper gyrus of leaves. Living in humid and dark environment for a long time, it is easy to get coal pollution. In summer, they will also be attacked by pests, such as thrips and scale insects.
When the temperature drops, keep it warm in time and put it in the air-conditioned room.
in order to avoid being damaged by pests, spray special insecticides in time. Ventilate in time, see the sun, and clean up the insects in time.
