For the combination fungicide timings, A+C gave the best results under low disease pressure, while B+C had the lowest pod infection and seed pick, and the highest yield under higher disease pressure.Continue readingThe timing of strobilurin fungicides to control anthracnose in 2005-2006

Burial of residue using tillage, along with milder and wetter weather encourages the break down of crop residue, and this kills anthracnose on the residue.Continue readingAnthracnose survival on dry bean plant residue 2016
Common bacterial blight (CBB) is a serious seed-borne disease of bean, affecting leaves, stems, pods and seed. Management includes disease free seed production and genetic resistance. The purpose of this study was to measure the effect of CBB resistant navy cultivars, under moderate/high disease pressure. Two resistant and four susceptible cultivars were tested at six…Continue readingImpact of common bacterial blight resistance in dry bean cultivars 2003-2004
Simulated hail damage reduced yield by 29%. Applying Quadris or Headline did not visibly reduce plant stress and did not result in a yield response to any cultivar or market class.Continue readingStrobilurin Fungicides for Plant Health in Dry Beans, 2009-2011
Anthracnose is a seed borne disease that reduces yield and seed quality. Seed treatments provide the first chemical defence for this disease. DCT (diazinon + captan + thiophanate-methyl) was the standard seed treatment in Ontario. Earlier work found that DCT was better than Apron Maxx (fludioxonil + metalaxyl-m) in managing early season anthracnose infection on…Continue readingImproved seed treatment for anthracnose in dry beans, 2007-2008
The purpose of this study was to find the best fungicide timing, in combination with a seed treatment, to manage anthracnose in a bean crop in Ontario and Manitoba.Continue readingAnthracnose control in bean with seed treatment and fungicide, 2005-2006
The purpose of this study was to measure product performance and return on investment, to help growers to select the best fungicide.Continue readingWhite Mold Fungicides for Dry Beans, 2009-2011
Can one fungicide manage white mold and anthracnose? The purpose of the study was to measure fungicide performance and economic returns for fungicides registered to control white mold. Continue readingAnthracnose Fungicides for Dry Beans, 2014-2018
Ontario growers routinely use fungicides to manage white mold is dry beans, but fungicides should be applied before any disease is visible. The purpose of this study was to measure the long-term performance and economic returns of fungicides, to help growers select a top product. Four small plot experiments were conducted in 2012-2013 at the…Continue readingWhite Mold Fungicides for Dry Beans, 2012-2013
