� Ethephon application advances harvest by 10-14 days.

� Early harvest avoids the need for final insecticide spray.

� Early harvest improves the quality of walnuts.

Kiwi: Growth Regulator Use

� 50% of the 1996 crop went unharvested due to small size.

� Research demonstrated that hydrogen cyanamide produces a uniform crop with larger sizes.
