Online published on 23 May, 2013. Abstract An experiment was conducted to evaluate the performance of different types of nozzles fitted with hand compression knapssac sprayer on deposition of Steinernema sayeedae, S. seemae, S. qazii. Five common nozzles viz., flood jet nozzle, flat fan nozzle, broad cone nozzle, hollow cone nozzle (plastic type) and hollow cone nozzle (brass type) were taken in this study. EPNs@50,000 IJs/lit.of water was sprayed on 8 chickpea leaves kept in a plastic trays. The number of live EPN deposited on each leaf was counted. Maximum EPN was deposited in case of flood jet nozzle (607 IJs/leaf) showing its superiority over others as this nozzle resulted in least shredding and clogging of EPNs. This was followed by flat fan nozzle, while broad cone nozzle and hollow con nozzle were found very detrimental to EPNs.
