It is well known that herbicide efficacy is strongly associated with environmental conditions (Kudsk and Kristensen, 1992), and this is why applicators are required (by law) to spray under specific environmental conditions. In recent years, we have witnessed an increase in extreme weather events that have emphasized the importance of maintaining proper environmental conditions at, but more importantly after herbicide application. As part of my PhD project, I demonstrated that the first 48 hours after treatment (HAT) with pinoxaden (Axial®,45 g L-1 EC, Syngenta, Switzerland) can have a major impact on the success of weed control (Matzrafi et al., 2016). To...

As we are in the mid-summer, many fields in the low desert region are preparing for soil solarization. Soil solarization is a widely adopted pest control method by organic growers in the low desert region. With the increase in organic production acreage in recent years, we are seeing more fields implementing soil solarization during summer.
Soil solarization is a method for controlling soilborne pathogens, insects, nematodes, and weed seeds & seedlings by disinfesting soil by the solar heat. Solarization is implemented during summer months, where soil is heated by covering with transparent polyethylene mulch/tarp. The plastic covering permits solar radiation/energy to penetrate and trap in the soil; thereby, building heat in...

I was inspired by Sarah Morran's blog post "Introducing new researchers in the UC Davis Weed Science Group" and decided to look at the other end of the spectrum.
Introducing retired researchers in the UC Davis Weed Science Group
What I did: During my 35-year career with USDA/ARS beginning in Denver in 1976 and then in Davis in 1980, my research was focused on developing better tools to manage aquatic invasive weeds by investigating key characteristics of these species including drivers and physiological controls of growth,.../h2>
