*.Max. application rate per season 2.18 kg/ha for cotton, 0.72 kg/ha for cereals, 1.44 kg/ha for fruit.
Applications Method Accelerating ripening and maturation of fruits by releasing ethylene. Fruits treated with ethephon showed rapid increase in respiratory rate.
The most suitable period is when the fruit begin to mature, when colored fruits begin to color, white fruits slightly turn yellow, then you would get the best effects.
Storage Keep in Dry and cool place. Store under acidic conditions
