Ethephon 2SL is a plant growth regulator used to promote earlier ripening and maturation of various crops, including apples, berries, cantaloupes, cherries, grapes, peppers, pineapple, sugarcane, tobacco, tomatoes, and walnuts. It is also used for lodging reduction in wheat and barley. The active ingredient is Ethephon at 21.7% by weight. This product is for commercial or agricultural use only and is not for residential use. When applying, ensure thorough spray coverage of foliage and fruit. Users must be cautious of spray drift, especially during temperature inversions or high winds, as it can affect non-target crops or sensitive areas.
