    Remove with pruners any isolated leaves with newly formed mines to stop a new leaf miner infestation before it can become serious. Monitor plants closely for the appearance of new mines. Wait for the appearance of one to three mines on each leaf before considering insecticides.
    Place plastic trays beneath the foliage of the affected tomato plants and check them daily for bright yellow leaf miner pupae. Kill those found by hand, but wait to apply an insecticide until you see 10 pupae appear daily over three to four days.
    Apply spinosad as a drench to the soil beneath the tomato's foliage to crops that are organically grown. Continue to monitor for new pupae using the plastic trays, and reapply spinosad every seven to 10 days until few or no pupae appear.
    Use a rotation of abamectin and cyromazine on the foliage of plants being produced using traditional chemical inputs. Apply abamectin first, and then wait two to three weeks to apply cyromazine. Repeat this rotation throughout the season, allowing two to three weeks between applications, until you no longer see leaf miners.
    Minimize leaf miner populations for the following year by plowing under spent tomato plants immediately. Rototill the garden thoroughly to ensure that pupae are buried deep underground.
