I have two ways to control leaf miner without using pesticide when growing organic vegetables, these ways are for family gardens with the small number of trees. If the leaf miner appears at a low density, it does not affect the trees, but with a high density, too many leaf miner cover the tree, making the tree less able to grow and low yield.
The leaf miner dig tunnels inside the leaves, so organic pesticide from garlic, ginger chili is ineffective.
