How do you prevent leaf spots?
Preventing Plant Leaf Spots For your houseplant, spotted leaves can be prevented by watering the soil and not the foliage. Leave enough space between your pots for good air circulation. In the garden, water in the early morning so the moisture will evaporate from the leaves. Closely packed foliage should be thinned.
How will you distinguish fungal leaf spot from bacterial leaf spot?
In order to distinguish between bacterial and fungal leaf diseases, one can put leaves in a moist chamber and check for fungal structures (little black dots in the lesions) after two to three days. Also, bacterial lesions will be ‘water-soaked’ or ‘glassy’ before they dry up, particularly if the environment is moist.
What causes spots on plant leaves?
Spotted leaves occur when fungal spores in the air find a warm, wet, plant surface to cling to. As soon as that microscopic spore gets comfortable in its new home, sporulation (the fungal method of reproduction) occurs and the tiny, brown fungal leaf spot begins to grow.
What is aphid honeydew?
Honeydew is a sugar-rich sticky liquid, secreted by aphids and some scale insects as they feed on plant sap. When their mouthpart penetrates the phloem, the sugary, high-pressure liquid is forced out of the anus of the aphid.

What causes transparent spots between leaf veins?
If transparent spots appear between leaf veins, it’s a sign that tropical plants are exposed to intense cold.
