1. WhiteflyBecause its leaves are very thick, they easily attract whiteflies, which will harm the leaves. However, this is not the only disadvantage. It can also help with pollination. However, if the number is large, it still needs to be removed as soon as possible. You can spray a certain concentration of pesticides and provide ventilation. 2. Scale InsectsScale insects are also one of the frequently occurring pests, and there are many types, such as shield scale, citrus mealy scale, and root mealy scale. They harm different parts of the plant, but the damage is all great. The citrus mealy scale is a small soft-bodied insect that sucks the juice inside. The other two types also suck the juice from the leaves and roots respectively, thus affecting the health of the plant and destroying its ornamental value. If the number is small, you can use a small brush dipped in alcohol to brush it off. If the number is large, you can spray it with a solution. It can be removed cleanly in about 2-3 times. If you only do it once, it may not be removed cleanly. 3. NematodesNematodes appear as small white threads and mainly harm the roots. Prevention is needed before potting. The soil and pots should be disinfected. If the disease has already occurred, the diseased roots need to be cut off and the healthy parts above should be used for cuttings. |
