This is usually caused by scale insects. These pests often hide at the junctions of leaf stems and branches, where they suck the plant’s sap. Over time, the affected leaves lose nutrients, leading to the appearance of white or yellowish spots, and in severe cases, the entire leaf may turn yellow.
To control the scale insect population, you can use Mr Ganick Scale Terminator RTU for home gardening, or Mr Ganick Scale Terminator Concentrate for larger planting areas (more economical for wide coverage). Spray once every 5 to 7 days, and continue monitoring the condition of the leaves until the pest problem is significantly reduced.
