What pesticides are effective for treating cacti scale insects
Cacti scale insects can weaken the growth of cacti, and in severe cases, can lead to plant withering and stem segment shedding, severely affecting their normal growth. This is usually caused by closely spaced potted plants around, poor ventilation, and the presence of weeds and dead branches, or the spread of scale insects from other potted plants near the cacti. Alcohol or white vinegar can be used to wipe, and if there are a large number of scale insects, pesticides like scale terminator or scale control can be diluted with water and sprayed on the affected areas.
