What exactly is the disease that causes worms on the back of Canary Moonflower leaves?
After enduring the severe heat of a summer, it is often found that the leaves of the Moonflower are prone to general scars, such as the ones shown below.
So what exactly is the problem? Is it a disease or pest damage? Many friends can't tell, but actually, this is a manifestation of pest damage.
Whenever friends ask about this situation, when I tell them it's pest damage, they often look puzzled and say: I looked, but I couldn't find any worms.
In fact, this type of worm is not mysterious at all. It's just that when we can see the worms, we often don't see the damage they cause. On the contrary, when we can't see the worms, the damage is more severe. This worm is called thrips.
Thrips are often visible in the light-colored blooms of Moonflowers in the spring and are very small insects, even smaller than ants. Generally, after the Moonflower finishes blooming in the spring, thrips will start to breed in large numbers.
What exactly is the disease that causes worms on the back of Canary Moonflower leaves?
In May and June, thrips lay their eggs on the back of the Moonflower leaves. At this time, it is often found that the leaves of the Moonflower are curling up with rice-like larvae on the back, which is the best time to eliminate thrips.
If no preventive measures are taken during the larval stage, then in the summer, thrips will become quite abundant, not only causing scars on the Moonflower leaves but also causing the new buds to wither, deform, and the leaves to become deformed, severely affecting the normal growth of the Moonflower.
For the control of thrips on Moonflowers, prevention is key. It is important to frequently apply pesticides. You can use insecticides along with fungicides when spraying to achieve a good preventive effect.
