Product Description: Insecticide-free cabbage fly control. The Dr. Stähler Plant Collar is a reliable repellent against cabbage flies. The plant collar prevents cabbage flies from getting to the root neck of the plants. This prevents egg laying. For vegetable cultivation, Dr. Stähler Plant Collar is a biological aid for increasing harvests. In addition, the plant collar improves the moisture and temperature conditions in the soil.
