London: Sugar declined in New York for the first time in four days before industry group Unica reports on the crop progress in Brazil, the world's largest producer.  Unica will provide an update on how much sugar cane was turned into ethanol and into sweetener in the first half of June.  Sugar prices have climbed 4.1% the past three days on speculation rain would slow progress in Brazil.  Raw sugar for October delivery fell 0.5% to 17.25 cents a pound by 8:07 a.m. on ICE Futures US in New York.  Cocoa gained 1.4% to $ 2,193 a tonne.
