Particle films do have limitations to efficacy, including being washed off in frequent or heavy rains. Overall, particle films …
New Grapefruit Rootstock, Scion Experiment
The world’s peerless grapefruit grows in the Indian River Citrus District. Balanced with sugar and tart, and a thin rind for easy peeling, the fruit is sold mostly for export to European and Asian markets, where it is a high-price delicacy.
