Aphids are a common pests that can be found on the undersides of your
muskmelon leaves. You’ll know they’re there if you see leaves turning
yellow and crinkling or curling.

Aphids suck the juice from your plant leaves and leave a sticky substance
behind. The only beneficiary of this process is ants, who harvest the sticky
sweet stuff.
The best solution to aphids is to import ladybugs to your garden. They feed
on aphids and are very effective in ridding your plants of these little
green, gray, or brown bugs.
Another solution is to “wash” them off with a hose and high-pressure spray
nozzle or an organic insecticidal soap. |
