TL;DR: The genotype-specific cross-resistance relationships between the SDHIs boscalid and penthiopyrad and the lack of cross-Resistance between these fungicides and fluopyram should be taken into account when selectingSDHIs for gummy stem blight management.

TL;DR: Yields and returns were correlated with spotted wilt intensity to a greater degree than leaf spot intensity, and the standard production system, Georgia Green in conventional tillage with seven sprays, resulted in lower returns than half the integrated systems tested in 2002 but had comparable or higher returns than nearly all systems in 2003.

TL;DR: The number of fungicide applications could be reduced without compromising control of leaf spot when reduced tillage is used, especially if combined with moderately resistant cultivars.

TL;DR: Results of this study confirm a significant relationship between in vitro sensitivity of Sclerotinia homoeocarpa and in planta control efficacy of propiconazole and provide evidence of field resistance to propiconzole in S. homoeOCarpa in Georgia.

TL;DR: Both mixtures and alternate applications of chlorothalonil and benomyl were effective for management of leaf spot in fields wherebenomyl alone did not provide season-long leaf spot control and neither tank mixes nor alternating sprays prevented an increase in the relative frequency of benomel-resistant isolates compared with other treatments in which benomy was used.
