Effect of Adhesives on the Retention of Bordeaux Misture on Arecanut Bunches

Author: M. Anandaraj


Bordeaux mixture is a copper compound which is extensively used to prevent fruit rot in arecanut (Areca catechu Linn.) caused by the fungus Phytophthora arecae (Coleman) Pethybridge. It is usually mixed with adhesives to improve its retention.
The quantity of copper retained on areca fruit surface sprayed with 1% Bordeaux mixture added with 0.1% of one of the three adhesives, viz., Triton Navacol and Carboxymethyl cellulose was estimated colorimetrically. No significant difference in copper retention was observed regardless of whether adhesives were added or not.

Keywords : Betel nut (Areca catechu). Bordeaux mixture. Spray adhesives.
