Spray deposition and abscission efficacy of CMN-Pyrazole in mechanical harvesting of Valencia orange

摘要

Tests were conducted to investigate the efficacy of an experimental abscission chemical, CMN-Pyrazole (CMN-P), in a commercial orange grove in south Florida. Application variables included sprayer type, spray volume rate, spray release height, and application time. Spray deposition was assessed by fluorometry and the chemical efficacy was quantified by measuring fruit detachment force and fruit removal by a trunk shaker
