Impact of Pyrilla perpusilla infestation on quality of cane crop
Overall season sugar recovery was recorded during Pyrilla perpusilla infestation year (2002)
and infestation free year (2003). The results indicated that different varieties behaved
differently to loss of sugar recovery % cane. Variety V4 showed stability in its quality during
both the years. Maximum loss of sugar recovery % cane was recorded in V1 followed by V2.
The variety V4 was relatively resistant to Pyrilla perpusilla. Data recorded on impact of
Pyrilla perpusilla infestation on quality of cane varieties is given in fig.4.
