CMNP is a chemical that is currently under review by the EPA for registration as an abscission-aiding compound. By loosening mature fruit, CMNP is expected to allow mechanical harvesting of Valencia oranges to continue well into May and June without significant losses of next year’s crop. Late season trials were conducted on a Lake Placid grove from early May through mid-June. Preliminary results showed significant treatment effects from spraying CMNP. Immature fruit losses were shown to be a result of higher canopy shaker frequencies and not from the CMNP treatments. Effects on next season’s yields will be assessed this fall and measured when the trials are repeated May and June of 2012.
