Widely used in organic farming today, neem oil is effective in controlling many insect pests, including leafminers [ 2 ].
To use neem oil for leaf miners , make a spray by mixing 2 tablespoons of neem oil in a gallon of water.
Shake well and spray the solution on affected plants. You can also use this organic pesticide to control insect pests in general and to keep the garden clear of mildew and fungus. A cover is usually placed over rows of developing plants or crops. Row covers protect young plants from harmful insects. They also give protection from birds, domestic pets, night frosts, or daytime sun damage.
You can buy variations or construct one homemade from fine mesh or other suitable lightweight fabrics. Remove the covers once the growing season is over. Tilling the soil after harvest can destroy any pupae in the soil. Also, it can prevent adult flies from emerging in the spring.
An old way of dealing effectively with annoying garden insects is to utilize sticky traps. These colored strips of sticky material attract pests that become stuck, unable to mate, lay eggs, or survive. Sticky traps are particularly useful, hung in greenhouses or near indoor plants.
Different colors attract different pests, with yellow or bright blue both being high attractants to the leaf miner fly. Removing leaf miner eggs by hand at the outset of any sign of the pests may be tedious but also effective. Another product you can use to get rid of leaf miners organically is Spinosad. Spray it on the leaves for direct contact with the critters. The effect of this insecticidal soap spray paralyzes leafminers and kills them in a day or two.
However, you may need more than one application in a growing season. If you have concerns about the toxicity of Spinosad, manufacturers state that it rates as low toxicity for mammals. However, it may be harmful to bees. Therefore, evening spraying or zero sprayings in the flowering period of plants may make this leafminer treatment more useful for severe infestations.
This one is increasingly popular in organic pest control and it also works for the treatment of leaf miners. Beneficial nematodes are tiny organisms occurring naturally in the soil. These microscopic roundworms are capable of destroying many garden pests at the developmental stage in the soil. The larvae live in the tunnels, eating their way through the leaves. That means that they are also excreting in the tunnels.
I don't think anyone wants to eat insect droppings! Answer: Yes, because the larvae live inside the leaves. If you are having a problem with leaf miners, do not use any infested cut foliage for floral arrangements. Discard it instead. Answer: Cutting back your plant in the fall will not prevent leaf miner infestation because the insects hibernate in the soil of your garden during the winter.
Only cut back your plant in the fall if it is a perennial which dies back to the roots in the fall. It is always a good idea to rid your garden of any dead plant material for the winter. If your plant is a perennial which doesn't die back to the roots in the fall, you should not cut it back.
Doing so will kill the plant. That is an excellent question! You should never re-use potting soil for the very reason that you cite: you can pass on disease, insect eggs, mold and fungi to new plants if you re-use the soil. Always use fresh potting soil when you plant your containers. It's also a good idea to clean and sterilize your containers before you re-use them for the same reasons.
I removed my potted plant that was overrun with leaf miners. Do I need to dump all the soil in the pot, or can I replant. I'm suspecting if the larvae are in the soil, I'll need to toss it all. Is that so? This is great information and I'll start right away pinching the leaves of my yellow squash which is where I'm seeing the leaf miner tracks. Thanks so much.
