How to prevent and treat multi肉 scale insects
Scale insects are one of the common pests in multi肉 plants. So, how should we prevent and treat scale insects when caring for multi肉 plants? Let's find out below.
How to prevent and treat multi肉 scale insects: Physical control
When scale insects appear on multi肉 plants, we can use tweezers or toothpicks to pick off and kill the scale insects from the plants. This method is suitable when there are a small number of scale insects.
We can also spray 75% alcohol on the multi肉 plants. Alcohol has good antibacterial and disinfectant properties and can effectively kill scale insects. When spraying alcohol, make sure to cover all areas evenly without leaving any死角.
Biological control
We can also use the natural enemies of scale insects to deal with them. The seven-spot ladybug is a beneficial insect that specializes in feeding on various pests. So, if there are seven-spot ladybugs in our environment, we can catch them and place them on the multi肉 plants. This way, the scale insects will be eliminated by the ladybugs.
Chemical control
Another method is to spray pesticides on multi肉 plants to kill the scale insects. Commonly used chemicals include 75% imidacloprid, thiamethoxam, and spirotetramat, which all have good killing effects.
If we use chemicals to kill scale insects, we should not place the multi肉 plants in direct sunlight after spraying the pesticide. This is because it can cause the plants to lose moisture, which will increase the concentration of the pesticide and may burn the plants. We should place the multi肉 plants in a shady environment for four to five days before gradually exposing them to direct sunlight. At the same time, proper ventilation should be maintained.
