AYALA ARMENTA, Quintín Armando et al. Bio-rational and conventional fungicides effectiveness on in vitro Sclerotinia sclerotiorum. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.spe11, pp.2149-2156. ISSN 2007-0934. https://doi.org/10.29312/remexca.v0i11.784.
In the northern State of Sinaloa white mold, caused by Sclerotinia sclerotiorum (Lib.) De Bary, is a disease affecting bean plants at any stage of development, including seedlings, mature plants and harvested fruits. Farmers often try to manage the disease by spraying fungicides, whose efficiency is often low because: a) not the most appropriate fungicides are used; b) are applied with poor coverage; c) there is a possible selection of resistance to these pesticides, among other reasons. The aim of this study was to determine the biological effectiveness, in vitro, of 10 conventional synthetic fungicides and 10 bio-rationales on Sclerotinia sclerotiorum, in different concentrations. Conventional fungicides pyraclostrobin + boscalid, carbendazim, fluazinam, fludioxonil and cyprodinil + prochloraz at all doses tested were the most effective against S. sclerotiorum. Bio-rational products, salicylic acid, hydrogen dioxide, grapefruit seed extract in the doses tested and citronella extract 1 000 ppm controlled the fungus in 100%.
