Mealybugs are a type of pest that can infest custard apples and other plants. They feed on the sap of the plant, causing damage to the foliage and fruit, and can also excrete a sticky substance called honeydew which can encourage the growth of sooty mold.
To control mealybugs, you can try physically removing them by wiping them off with a cloth, or using insecticidal soap or neem oil. Spray BUPROFEZIN 25% SC @ 12 ml/15 lts of water along with a good quality sticker.
It’s important to keep the plant free of dead leaves and debris, which can harbor the pests, and to monitor the plant regularly for signs of infestation.
