Spray nozzles are an important part of your herbicide application program. There are many different types of nozzles available from manufacturers, and each nozzle can perform differently. Review some guidelines for selecting the proper spray nozzles and operating them effectively.Read More
Dr. Mark Renz and Tony Summers with the University of Wisconsin conducted a field study in 2014 in McFarland, Wisconsin to determine if the amount of spray volume would impact knotweed control with Milestone at the spot treatment rate of 14 fluid ounces per acre (fl oz/A).Read More
Undesirable or invasive woody vegetation threatens the biology and ecology of grasslands and native woodlands. This article describes various techniques for applying selective herbicides to improve success of woody plant control.Read 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.
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
Herbicides are an important tool for removing noxious or invasive weeds from plant communities, allowing desirable vegetation to respond. Field research trials were established to determine if warm and cool season grasses could be planted either in late autumn as a dormant fall planting or in the spring after a September application of herbicide.Read More
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
Practical guidelines for cleaning and winterizing your truck-mounted, ATV, or backpack sprayers.
Proper cleaning and winterization of herbicide application equipment is important to ensure safe storage over the winter. Spending a little extra time in the fall will save you time and money next spray season!
The USDA Plants database lists more than 20 Rubus species (and associated hybrids) that were introduced to North America. Himalayan blackberry (Rubus armeniacus) and cutleaf blackberry (Rubus laciniatus) are the two most widespread of the invasive blackberry species.Read More
Managing incompatible woody vegetation along utility and transportation rights-of-way (ROW) requires careful planning, consistent budgets, and judicious allocation of time and resources. When budgets or resources are inadequate, planned vegetation maintenance may be postponed to the following growing season or beyond. While delaying maintenance for even one year allows woody vegetation to increase in density and height, the actual increase in time and material to control the vegetation after one or more years of delayed treatment has not been determined.Read More
Choosing the right herbicide to fit your vegetation management objectives is an important decision. Herbicides are classified in a number of ways based on how they are used and their selectivity on different plant families.Read More
The restoration project in southeastern New Mexico encompasses about 6.5 million acres of rangeland in a four-county area. Herbicide application, mechanical removal, biological control, prescribed fire, and reseeding have been implemented to restore about 1.5 million acres.Read More
