Evaluation of bupirimate against rose powdery mildew

Abstract

Bupirimate 25% Emulsifiable concentrate (EC) was evaluated for efficacy on Sphaerotheca pannosa, the causal agent of rose powdery mildew in vivo. In this experiment Bupirimate 25% EC 6 ml/L and 4 ml/L effectively reduced the powdery mildew infection over rest of the treatments and improved the flower yield. Moreover, application of Bupirimate 25% EC at the doses of 2, 4 and 6 ml/L and even at higher dose 8 ml/L did not show any phyto-toxic symptoms on rose plant. Thus, Bupirimate 25% EC may be considered as compared to other fungicides.

Disease management of rose powdery mildew using some fungicides and biofungicides

“…Bupirimate (25% EC) could control rose powdery mildew. The present study was initiated with the bioefficacy and phytotoxicity of bupirimate 25% EC against powdery mildew disease in rose (Adhikary et al, 2017). Additionally, fungicides have negative effects on beneficial microorganisms and insects; therefore, the search for environmentally sound alternatives to fungicides is required.…”
