A list of wildflower options for a seeding mix that is tolerant to Milestone herbicide, and includes diverse structural diversity (height) and flowering times for pollinators.Read More
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
Several herbicide applicators have been diagnosed with ‘trigger thumb’ (Stenosing tenosynovitis) or ligament damage to the thumb possibly caused by excessive use, and/or stiff spring pressure with some handgun applicators.Read More
Researchers conducted a study near Matlock, Washington investigating the potential of logging debris and herbicide combinations to inhibit germination and development of Scotch broom (Cytisus scoparius) seedlings. The study site was a mature Douglas-fir forest that was scheduled for harvest. The forest understory included occasional Scotch broom plants that invaded from a previous disturbance, indicating the likely presence of soil-stored seed.Read More
We asked 13 invasive plant management professionals to provide insight and tips on nozzle selection and maintenance based on their field experience. See what the professionals suggest for type and size of nozzles for backpack and ATV/UTV or truck-mounted sprayers, supplemental equipment, and best practices for calibrating, maintaining, and replacing nozzles.

Infested acreage and the time required to estimate it were compared for two inventory methods: a traditional method of mapping on foot with handheld GPS units versus an experimental method of recording video of infestations while riding a mountain bike.Read More
All-Terrain Vehicles (ATVs/ 4 Wheelers) and Utility Vehicles (UTVs/ Side by Side) have become essential tools for land managers working in range, prairie or forest lands. With diverse models and brands on the market right now, how do you select vehicles and application systems that are best for you?Read More
Herbicide Ballistic Technology (HBT) is a novel application technique designed to deliver encapsulated herbicide projectiles with long-range accuracy and precision. The performance of an HBT platform for controlling newly invading miconia (Miconia calvescens DC.) plants while conducting helicopter surveillance for remote infestations in Hawaii’s remote watersheds is evaluated in the article. This research article demonstrates the capability of this technique for rapid-response control of remote satellite plant detections.Read More
This basic guide written by James Leary, Jane Reppun Beachy, Amanda Hardman, and Julia Gustine Lee, is for practitioners to conduct their own experiments, testing registered, non-restricted herbicides using the Incision Point Application (IPA) technique on invasive woody species of interest.Read More
