Leaf blight is also known as blight or leaf spot. At the beginning of the disease, there are small brown spots on the leaves of plants. At the middle stage, the brown spots gradually become large patches, and the color gradually deepens. At the later stage, the large patches become one after another, which makes the whole leaves wither or even necrosis. The control method is very simple, only need to use mancozeb wettable powder to spray properly.
Scale insects are a kind of pests with strong reproductive capacity. They are concentrated on leaves and branches and suck the nutrients of staghorn fern. If there are too many pests, the whole plant of staghorn fern will wither or even die. The control methods are divided into two categories: artificial control and drug control. The artificial control is applicable to the initial stage, only when there are pests on one or two branches, it can be directly brushed with soft brush. The drug control can be used in the later stage, when there are many pests, spray malathion or dichlorvos once a week, and two or three times can eliminate the pests.
Aphids mainly appear in the young growth stage of staghorn fern, distributed on the young branches and leaves of staghorn fern, and absorb its nutrients, so that it can not grow normally. Early prevention and control can spray soap water, later directly spray drugs can
