1. Bamboo locustThis insect has a good growth ability and develops and reproduces very quickly. You should check the plants more often and take immediate action if you find it. Prevention and control measures: First, brush off the insects, and then use 90% concentration of dichlorvos to spray them, because there will be some bamboo locusts hidden on the plants, and it is difficult to eliminate them completely without using drugs. 2. Scale InsectsKeeping the plants in a hot, humid and poorly ventilated environment makes this type of pest more likely to occur. It will erode the nutrients in the leaves, causing them to turn yellow, and when there are too many insects, the entire plant may die. Prevention and control measures: If the number is small, you can wipe it with alcohol or detergent water to wipe off all the insects. If the number is large, you need to spray the medicine on the basis of wiping. It is recommended to use 40% concentration of omethoate for spraying, or 50% concentration of dichlorvos for spraying. Take the medicine regularly, once a week, and you will see results after about 2-3 times. |
