dc.description.abstractThe present investigation deals with the extraction and chemical investigation of lemon and citronella grass essentiall oil and their emulsifiable concentrates (EC) formulation as fungicide against Phomopsis vexans. GC-MS analysis of the lemongrass EO revealed citral B (37.75%), citral A (21.93%) and farnesene (8.80%) as the major compounds whereas citronella grass EO showed citronellal (24.80%), geraniol (21.88%) and citronellol (14.58%) as major compound. EC formulations comprising of EO were prepared using castor oil as solvent and emulsifier blends (10%) with hydrophilic-lipophilic balance (HLB) value (12.86) suitable for the EO formulation. Among six EC formulations prepared from each EO, CF6 and LF6 type performed well in terms of emulsion stability, cold test, accelerated storage and foam test indicating feasibility for their commercial production. EC50 value of citronella, lemon grass EO and EC formulations CF6 and LF6 were 0.0087, 0.0098, 0.009 and 0.0126, respectively which were tested by Poisoned Food Technique and were compareable with Zineb 75 WP. CF6 and LF6 formulation at 0.1% inhibits the growth of P. vexans under field condition. Among all the tested components, CF6 formulation was better as compared to LF6 formulation. EC formulations are the better way for the effective application of EO under in vitro and in vivo condition as they are easy to prepare and can be used ecofriendly.en_US
