Petroleum Oils as Navel Orange and Tangelo Fruit Thinning Agents

Since the 2001-02 crop year, the major objective of this project has been to determine how a summer application of I 0 gallons of a 440-weight narrow-range petroleum oil in a 200-gallon per-acre spray solution affects the alternate bearing, fruit size and yield of Minneola tangelo. In this report, the year refers to the year that the crop was harvested (which was in the spring following the previous year’s late summer oil application).
