Powdery mildew is cause by a biotrophic, obligate fungus Uncinula necator now known as Erysiphe necator (Schw.) Burr (Sall, M. A. 1980). It is the most devastating and widespread disease of grapevine in the world and causes the significant loss to grape yield and quality (Gadoury et al. 2012). This is the major grape vine disease causing significant yield reduction each year in California, which is the top grape producing state in the United States (Gubler et al. 1999). This disease infect all the
Mildew needs a damp environment to grow. When water damage occurs because of leaks, floods, or even high humidity, this detrimental fungus can fester. When growth becomes a problem, it can ruin a St. Louis, MO, home or business and cause respiratory issues, eye irritation, or skin rashes. There are steps that should be taken immediately to address a mold and mildew problem.

This common stone-fruit disease, which starts at bloom and often affects fruit that's stuck together in clusters, is triggered
composition. Prepare for Phase 3, including working with Danielle Gibbs to contact tree fruit and produce plots for testing. Plots will have powdery mildew at late summer and individual plants will be marked for treatments next season prior to sporulation. Leaves free of powdery mildew will also be marked, and the distance of each leaf from powdery mildew will be recorded to indicate whether the disease grows, diminishes, or remains unchanged.

This week, after reading Eaarth by Bill McKibben, I became very interested in global warming. Global warming is defined as an increase in the earth 's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. Global warming is also known as climate change or the greenhouse effect. The main cause of global warming is too much carbon dioxide being contained in the atmosphere. Carbon dioxide, however, absorbs heat and then warms the
The region that I will be picking for this report is the Okanagan Valley in British Columbia. It is located in the southern part of the province. It is the second largest wine region with approximately 4000 hectares of vineyards (“Okanagan Wine”, n.d.). The region grows slight more red grapes compared to whites. According to a report by Bremmer (2014), white grape varieties represent 49%, whereas reds represents 51%. Some of the wines that are famous in this location include Merlot, Cabernet Sauvignon
