Abstract

Previous research in our laboratory provided evidence that hydrogen cyanamide (HC) applied to grapevines ( Vitis vinifera ) to stimulate budbreak resulted in ethylene production, which, in addition to HC drift at application, caused abscission of leaves in neighboring `Eureka' lemon [ Citrus limon (L.) Burm. F.] orchards. Foliar-applied hydrated lime [Ca(OH) 2 ] at 140 kg per 2337 to 2807 L·ha -1 to commercial `Thompson Seedless', `Perlette', `Red Flame', or `Princess' vineyards 2–48 h after HC treatment reduced leaf abscission from 2-year-old'Eureka' lemon trees placed inside the vineyards, with no negative effects on budbreak or yield of any grape cultivar. Hydrated lime is an effective inexpensive tool that grape growers can use to protect neighboring lemon orchards.
