Russian knapweed (Acroptilon repens) is a creeping perennial that spreads through seed and vegetative root buds. Once established, infestations expand primarily by adventitious roots.Read More
Silverleaf nightshade (Solanum elaeagnifolium) and Carolina horsenettle (Solanum carolinense), also known as horse nettle or bull nettle, are deep-rooted, herbaceous, perennial plants in the nightshade family. Article discusses distribution and management of the two invasive nightshadesRead More
Autumn olive is an invasive woody shrub or small tree that grows to about 20 feet in height. The plant is commonly found invading open and early-successional woodlands, abandoned agricultural fields, and edges of streams and rivers.Read More
All-terrain vehicles (ATVs) with small-capacity spray tanks and boomless nozzle systems are well adapted to uneven terrain and are thought to have potential to spray 25 to 30-foot swaths using a centrally located single or dual nozzle arrangement. This article summarizes field studies by Robert Wolf and others at Kansas State University to evaluate the effectiveness of spray nozzles on ATVs.
This article summarizes key points for you to consider before purchasing a backpack sprayer and provides backpack sprayer calibration guidelines and maintenance tips. It also includes reviews of backpack sprayer equipment that some of our readers are currently using in field operations.Read More
An article by Byron Sleugh, Mary Halstvedt, Chad Cummings, Vanelle Peterson, Dow AgroSciences, Indianapolis, IN; and Robert G. Wilson, University of Nebraska Panhandle Research Center, Scottsbluff, NE from 2010 Western Society of Weed Science Proceedings.
Studies were initiated by the University of Hawai’i Cooperative Extension Service Invasive Weed Management Program to find a method to improve individual plant herbicide application techniques and determine efficacy of various herbicides applied as undiluted formulations.
Catastrophic fire seasons of recent decades prompted a number of agencies and researchers to synthesize and expand upon the knowledge-base related to invasive plant issues following wildfires. The following short list of literature reviews, handbooks, and recently published research provides a starting point for exploring issues and developing management guidelines related to invasive plants following wildfires.Read More
New technology for treating invasive plants in inaccessible areas—Engineering firms specializing in mobile robotic systems have developed multirotor drones (Unmanned Aerial Vehicle- UAV) complete with a lightweight spray system that can be used for a variety of agricultural applications.Read More
A research project was initiated on a 10,670-acre ranch near Cimmarron, Colorado to develop sustainable management strategies for musk and Canada thistle. Objectives of the study were three-fold: 1) Investigate invasive thistle distribution through geospatial analysis; 2) determine effects of musk thistle management on forage quality and native plant diversity; and 3) develop a sustainable invasive plant management plan for the ranch.Read More
The new pulse sprayer technology is being tested to determine its application on range, pasture and natural areas. This technology keeps droplet size large (to prevent drift) by changing the pulsing cycle (nozzle on/off) instead of pressure which changes the droplet size. This could be very useful on rough terrain where it is difficult to maintain constant speeds.Read More
