ASSESSMENT OF LOW COST PERFORATED POLYTHENE COVER AS NON-CHEMICAL APPROACH TO CONTROL SCARRING BEETLE AND QUALITY BANANA PRODUCTION
Investigation was carried out in North 24 Pargana district of West Bengal, India to standardize the suitability of perforated polythene cover against scarring beetle of Grande Naine banana. Polythene cover of different perforations (15 and 20%) was tried. The results revealed that bunch covering with polythene completely controlled the incidence of scarring beetle irrespective of the percentage of perforation. The results also showed that bunches covered with 20% perforated polythene bag significantly increased yield (44.23 t ha-1), fruit weight (111.29 g), bunch weight (15.91 kg) and benefit cost ratio (2.64). Bunches covered with 15% perforated polythene showed the maximum TSS:acid ratio of fruit (67.77) compared with 41.07 in control. An increase in temperature and relative humidity and decrease in light transmission was recorded inside the polythene cover. It is suggested to use bunch covering with 20% perforation polythene to control scarring beetle infestation and quality banana production.
