Abstract

The present investigation was carried out to study the
efficiencies of agricultural practices i.e. rowing space, fertilization,
irrigation system, ratoons, varieties and host range on the
population density of red striped soft scale, Pulvinaria tenuivalvata
(Newstead) at Nagada, Armant and Luxor City, Qena governorate
during two successive seasons 2002 and 2003 where the results
clearly showed that planting sugarcane on 7 rows space, using the
recommended nitrogen fertilizer 200 units with 100 kg potassium
per feddan, using modern irrigation, and choosing PH 8013 variety
were considered the proper agricultural practices which decreased
the population of P. tenuivalvata, and resulted in the increasing of
both sugarcane yield and juice.
