The field experiment was conducted with twenty brinjal varieties/lines during October 2007 to May 2008 to identify shoot and leaf characteristics of brinjal plants for their susceptibility/resistance against brinjal shoot and fruit borer infestation. Borer infestation was influenced by different characters of plant shoot and leaf. Various parameters like plant height, stem diameter, number of b...
To justify the cost effectiveness of sex pheromones for the control of the stem borer Chilo sacchariphagus Bojer in sugarcane, the relationship between the per cent internodes bored and the various yield parameters, i.e. pol % cane, purity, fibre % cane, industrial recoverable sugar % cane (IRSC) and weight had to be determined. Analyses were made on cane samples, with varying degrees of infest...
