| Target Object | promote pre-harvest ripening in apples, tomatoes, coffee, and others, and post-harvest ripening in bananas and mangoes. It aids harvesting by loosening fruits like cherries and apples, prevents lodging in cereals, and improves yields in cotton, cucumbers, and walnuts. It also induces flowering in pineapples and bromeliads, stimulates latex in rubber trees, and enhances sturdiness in onion seed crops. |
| Mode of Action | Plant growth regulator with systemic properties. Penetrates into the plant tissues, and is decomposed to ethylene, which affects the growth processes |
