HORT TECHNOLOGY - OCT 2011 - Impact of Fungicide Program and Powdery Mildew Resistance in Three Varieties of Pumpkin + Author Affiliations The effects of fungicide program and varietal resistance on the development of cucurbit powdery mildew [PM (Podosphaera xanthii)] in pumpkin (Cucurbita pepo) were tested in 2009 and 2010 in Lexington, KY. Three fungicide programs consisted of a no-fungicide control, low input (chlorothalonil), and high input (chlorothalonil alternated with myclobutanil) were applied to three varieties of pumpkin with different levels of cucurbit PM resistance. Varieties tested were Howden, Aladdin, and Camaro, which had no, moderate, and high levels of cucurbit PM resistance, respectively. There were no significant variety by fungicide program interactions for yield, number fruit per acre, and average fruit weight in both years. In 2009 and 2010, variety significantly affected yield.

BLOG DE Nicole WARDUK 27/08/12 Fungicide-Resistant Downy Mildew Detected in Kentucky Vineyard This summer, a grape grower in central Kentucky reported persistent downy mildew in his vineyard. He noted that regular applications of Abound and Pristine fungicides failed to manage the disease. After laboratory analysis, the pathogen was deemed completely resistant to the two fungicides at the lowest recommended rates and 85% resistant at the highest recommended rates. What is fungicide resistance? In the simplest terms, pathogens become resistant to fungicides when the chemical no longer manages disease symptoms. How did resistance develop? Consider that it is highly unlikely that a fungal population will incur resistance to more than one chemical type, at least over the short term. Chemical groups are classified by biochemical mode of action, not necessarily by active ingredient. Considering that all fungicides within the same group have the same mode of action, it is clear that if a grower fails to properly rotate fungicide groups, fungicide resistance risk is high. What next?

SCI. - SEPT 2011 - Effects of disease control by fungicides on greenhouse gas emissions by UK arable crop production Page 1 Research Article Received: 4 October 2010 Revised: 21 January 2011 Accepted: 31 January 2011 Published online in Wiley Online Library: 14 April 2011 (wileyonlinelibrary.com) DOI 10.1002/ps.2151 Effects of disease control by fungicides on greenhouse gas emissions by UK arable crop production David J Hughes,a,b Jonathan SWest,a Simon D Atkins,a Peter Gladders,c Michael J Jegerb and Bruce DL Fitta∗ Abstract BACKGROUND: The UK government has published plans to reduce UK agriculture’s greenhouse gas (GHG) emissions. same time, the goal of global food security requires an increase in arable crop yields. fungicides have an important role in meeting both objectives. RESULTS: It is estimated that UK winter barley production is associated with GHG emissions of 2770 kg CO2 eq. ha−1 of crop and 355 kg CO2 eq. t−1 of grain. CO2 eq. t−1 in UK winter barley and 29–39 kg CO2 eq. t−1 in UK spring barley. disease control on yield and to variant GHG emissions assumptions is presented. a tonne of grain. c Yield

GRDC_COM_AU - MARS 2017 - Fungicide resistance discovery calls for urgent action Dr Fran Lopez-Ruiz from the Fungicide Resistance Group (FRG) at the Centre for Crop and Disease Management: “If we act now, we will have more chances of maintaining the efficacy of this group of fungicides for as long as possible.” Photo: CCDM Australian grain growers are being advised to implement effective integrated disease management strategies following the discovery of resistance to strobilurin fungicides in wheat powdery mildew (WPM). The resistance was found in 2016 crop samples from Victoria and Tasmania by the Fungicide Resistance Group (FRG) at the Centre for Crop and Disease Management (CCDM), a national research centre co-supported by Curtin University and the Grains Research and Development Corporation (GRDC). The researchers have confirmed the WPM mutation associated with the recently discovered strobilurin (Group 11, QoI fungicides) resistance is G143A, a mutation well known throughout other parts of the world but until now previously undetected in Australia.
