If you see white lines on your vegetables, don’t be shock. Let Modern Farmer help you to resolve the issue.
These are Leaf Miners.
Leaf Miners are a fairly common garden pest that feed on the inside of plant leaf tissue. You will often notice them in your garden by the white looking designs they leave on your plant leaves. Those white squiggly lines are a trademark of leaf miners.
Leaf miners are insect larvae which hatch from eggs deposited between the upper and lower surface of plant leaves.
How do I get rid of leaf miners?
The most common method to rid plants of leaf miners is to spray general pesticide on the infected plants. The trick to this method of how to kill leaf miners is to spray at right time. If you spray too early or too late, the pesticide will not reach the leaf miner larva and will not kill the leaf miner flies
