Evaluation of a New Strobilurin Group of Fungicide for the Management of Blast Disease of Paddy
Journal Title: Journal of Experimental Agriculture International - Year 2016, Vol 13, Issue 5
Abstract
A new strobilurin group of fungicide, pyraclostrobin 100 g/l CS (Seltima 100 g/l CS) was evaluated for its bio-efficacy against rice leaf blast disease under field condition during Kharif 2013 and 2014 at Agricultural research station, Gangavathi, Karnataka, India. The test fungicide, pyraclostrobin 100 g/l CS was found effective against leaf blast disease which recorded least percent disease index (PDI) of 14.20 and 16.48 @ 75 g a.i./h and @ 100 g a.i./h, respectively. Other fungicides such as tricyclazole 75 WP (300 g/h), Carbendazim 50 WP (500g/h) and Isoprothiolane 40 EC (750 ml/h) recorded significantly more PDI than pyraclostrobin 100 g/l CS. Due to difference in the PDI of leaf blast disease, different treatments recorded statistically significant yield differences. The highest yield (67.78 q/h) was recorded in the treatment of pyraclostrobin 100 g/l CS @ 75 g a.i./h followed by the same chemical @ 100 g a.i./h (66.87 q/h). Therefore, pyraclostrobin 100 g/l CS (Seltima 100 g/l CS) @ 75-100 g a.i/h can be used for effective management of leaf blast disease.
