Current & Future Technologies of Weed Spraying

11/03/2017

By Gwen Hoheisel, Regional Extension Specialist in tree fruit, grape and berry, WSU

This talk will discuss the current and future trends in application technology and farming. Precision agriculture is common in many commodities but precision application or spraying is not common.  Application practices globally are on a continuum of remedial methods to extremely innovative. We must be aware of where we are on the spectrum and what improvements we can make by adopting smart technologies. Specific items to discuss are rate controllers, automatic weed identification, and precision sprayers. As markets and regulations change and chemicals become more selective, we will need to adopt these advances to stay relevant and viable.

​Roadside Vegetation Management and the Highway Activity Tracking System (HATS)

11/03/2017

By Ray Willard, Washington State Department of Transportation, Olympia, WA

​Impacts of Invasive Parrotfeather on Fish Habitat in the Chehalis River

11/02/2017

By Lauren Kuehne, University of Washington, Seattle, WA

Aquatic plants form the basis of many freshwater food webs, and invasive plants have the potential to disrupt ecological processes by altering the way that resources and nutrients move to higher trophic levels. However, it can be difficult to comprehensively measure the impact of a particular species and understand the mechanisms of ecosystem change. We used a multi-trophic approach to assess the impacts of non-native parrotfeather (Myriophyllumaquaticum) on fish habitat in the Chehalis River, WA. We sampled 22 similar areas with and without parrotfeather over two years to characterize the impacts of parrotfeather on water quality, invertebrates, fish and plant communities. We also conducted a paired laboratory experiment to characterize and contrast the physical structure of parrotfeatherwith the native plant community. In addition to documenting the ways in which parrotfeather and other aquatic invasive plants can impact aquatic ecosystems, we also compared the current distribution of parrotfeather with the results of a similar survey conducted 20 years prior to assess spread and persistence over time.

Pesticides to be discussed:  imazapyr, 2-4D, carfentrazone, and glyphosate

Testing for Pesticides: Sampling Considerations and Analytical Methods

11/02/2017

By Dr. Todd Taruscio, Anateck Labs, Moscow, ID

Anatek Labs is a multi-state certified analytical laboratory that was established in 1992 and continues to provide comprehensive analytical services in many areas of environmental chemistry.  Anatek Labs provides drinking water and waste water testing in accordance with the Safe Drinking Water Act and Clean Water Act as well as soil and solid sample testing for a variety of regulated and unregulated hazardous wastes.  Anatek has developed many proprietary methods for the analyses of pesticide residues in soils and plant materials using powerful analytical tools such as LC/MS/MS and GC/MS/MS that can help resolve pesticide application errors and determine if pesticide persistence may be reducing crop yields.
