“…Specific for mature citrus fruit loosening within a wide concentration range (Burns, 2002) 20, 200, 1000, and 2000 ppm Coronatine A natural compound produced by fermentation with Pseudomonas syringae pv glycinea; is classified as a methyl jasmonate biological mimic; loosens mature citrus fruit (Burns et al, 2003); causes transient chlorosis; expect %10% defoliation; does not cause young fruit abscission 200 ppm Dikegulac A pinching agent; in citrus, is thought to disrupt auxin-ethylene balance and accelerate abscission (Pozo et al, 2004); expect 15% to 20% leaf loss at certain times of the season 20, 200, 1000, and 2000 ppm Maxcel Benzyladenine, used as an apple-thinning agent (Dennis and Hull, 2003) 20, 200, and 600 ppm Methyl jasmonate A natural compound found in plants; thought of as an ''octadecanoid signal'' derived from lipid signaling; can advance many senescence-related processes such as color change; loosens mature citrus fruit but causes %20% defoliation when applied to citrus (Hartmond et al, 2000) 0.2, 2, 10, and 20 mM; %45, 445, 2240, and 4485 ppm VBC-30050 Proprietary compound 20, 200, and 500 ppm four representative clusters were collected from each of four vines and 10 rachis sections were prepared from each cluster. Fruit detachment force was measured from berries attached to each section as described previously.…”
