TESTING OF SOME NEW AND EXISTING MOLECULES AGAINST YELLOW STEM BORER IN RICE IN PUSA, INDIAAmit Kumar, A. K. Misra, Paidi Satyanarayana, C. R. Kumbhar, Jitendra Kumar and Santeshwari
The pooled data indicated that fipronil (5SC) @ 25.0 g a.i./ha resulted lower infestation (8.21%DH) followed by carbofuran (3G) @ 1.0 kg a.i./ha (8.76%DH), acephate (95SG) @ 592 g/ha (8.87%DH) and higher infestation in control (26.74%DH). Similar trend was followed in case of white earhead formation. Maximum grain yield and cost benefit ratio was observed in fipronil (5SC) @ 25.0 g a.i./ha (54.86 q/ha and 1:22.38), based on this findings fipronil (5SC) @ 25.0 g a.i./ha was found to be the best treatment against yellow stem borer in rice.
