Description Ephon Top is a soluble concentrate growth regulator containing 660 g/L ethephon, used to reduce lodging risk in winter and spring cereals. It works by releasing ethylene within the plant, which shortens and strengthens stems, improving crop stability and harvest efficiency. Active Ingredient: Ethephon – 660 g/L Rates of Use: Winter barley: 0.75L/ha (GS 49 – first spikelet visible) Spring barley: 0.5 L/ha (GS 49) Winter & Spring wheat: 0.75 L/ha (GS 49) Durum wheat: 0.75 L/ha (GS 49) Rye: 1.1 L/ha (GS 49) Triticale: 0.75 L/ha (GS 49) Water Volume: 100–400 L/ha Application Timing: From GS 31 (first node detectable) to GS 49 depending on crop Best results on early-drilled, high-yielding crops with lodging risk Can be used after chlormequat for sequential lodging control Mode of Action: Systemic growth regulator Releases ethylene inside plant tissues, reducing internode elongation and increasing stem strength Restrictions & Warnings: For professional use only Do not treat crops under stress (drought, poor soil, pest/disease)
