RT Journal Article SR Electronic T1 Effect of Wetting Agents on 'Thompson Seedless' and 'Perlette' Grapes JF American Journal of Enology and Viticulture JO Am J Enol Vitic.

Pool YR 1971 UL http://www.ajevonline.org/content/22/1/40.abstract AB Dipping clusters of 'Perlette' and 'Thompson Seedless' into various concentrations of three wettingagent formulations had toxic effects on berry surfaces. Low concentrations resulted in a 1ight "ring scarring." With increasing concentrations of wetting agents, heavy "ring scarring," "buckskin-type" corky areas, and reduction of berry size occurred. The most severe injury consisted of small berries often entirely covered with cork, sometimes splitting, and in many cases berries died. 'Perlette' grapes were more sensitive to injury than were 'Thompson Seedless.'
