WALL AGAINST THE LEEK WORM
Ready-to-use solution based on nettle for foliar spraying against leek worms. Can be used in organic farming. The treatment repels and thus prevents the laying of eggs by the butterfly responsible for the leek worm. Use preferably as a preventative measure. In the event of a proven infestation, treat quickly to prevent the worms from settling deep. How to use the wall against leek worms? Liquid preparation to be used without dilution. Shake before use. Apply as a fine spray to avoid any excess or runoff. Spray all over the foliage as soon as the leeks are transplanted. Renew the spray every week on the leaves and more particularly on the heart of the leeks. In the event of a major infestation, re-spray every 2 to 3 days. Do not treat if there is a high risk of rain or in full sun. Preferably treat at the beginning or end of the day.
