The old saying, “Everything's fine until it's not,” comes to mind when dealing with some tough to control perennial weeds in alfalfa production during the summertime. Such was the case for an alfalfa field in the Sacramento Valley, where weed control seemed good up until mid-summer, and then it wasn't. Perennial weeds that started off small and overlooked, grew through the season, persisting through multiple cuttings, including curly dock, plantain, and nutsedge. For tough to control weeds in alfalfa fields, one needs to determine: 1) What types of perennial weeds are present, and 2) How many of them are there, to make a decision on how to manage them. These sorts of weed issues can creep up quickly in older alfalfa...

Glyphosate was commercialized in 1974. Since then, it has become one of the most widely used and studied herbicides. According to Duke (2018b), almost 20,000 scientific publications and patents have included glyphosate as a focus; only 2,4-D surpasses it with respect to citations. The articles in the 5th issue of the 74th volume of Pest Management Science are no different; they all focus on this important (and controversial) molecule.This special issue arose from a day long symposium organized by Stephen O. Duke (University of Mississippi) and Keith Solomon (University of Guelph) that was held at the 252nd annual meeting of the American Chemical Society (Duke 2018a).

The United States Geological Survey (https://www.usgs.gov/) defines drought as a 'period of drier than normal conditions that results in water-related problems.' Short-term effects of drought include: declines in surface water flows, which can impact water supplies for agricultural, urban, and environmental uses. Long term effects of drought can include aquifer overdrafts and land subsidence. California has experienced drought events in the past (most recently: 1976-1977, 1986-1992, 2007-2009, and 2011-2017) and is expected to experience many more in the future. While a changing climate and variable weather patterns are contributing to the California's water issues, a lack of new water projects, a...
