Dormant Season Management Recommendations for Russian Olive

Dormant Season Management Recommendations for Russian Olive

Russian olive (Elaeagnus angustifolia) is a rapid-growing, deciduous, woody shrub or small tree that is invasive in riparian areas, lake shores and natural areas. The invasive plant can cause serious ecological changes to riparian habitats with impacts to wildlife and watershed values, agriculture, and recreation. There are several management options for Russian olive depending on tree size, density, and environmental constraints. The following information summarizes herbicide options for Russian olive management that can be used any time of the year including winter and early spring when trees are dormant.

Autumn Olive and Russian Olive—What’s the Difference?

Autumn Olive and Russian Olive—What’s the Difference?

Autumn olive (Elaeagnus umbellata) and Russian olive (Elaeagnus angustifolia) are invasive, deciduous, woody shrubs or small trees that were introduced for landscaping, soil stabilization, and wildlife food/cover. Both plants became invasive in riparian areas, open forests, lake shores, and abandoned fields.

Understanding Performance of Your ATV-Mounted Boomless Spray Nozzles

Understanding Performance of Your ATV-Mounted Boomless Spray Nozzles

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.

Integrative Management of Sericea Lespedeza in Prairie Restorations

Integrative Management of Sericea Lespedeza in Prairie Restorations

Researchers at Southern Illinois University conducted a study on sericea lespedeza in the Crab Orchard National Wildlife Refuge. The goal of the research was to explore a comprehensive approach to reducing the abundance of sericea lespedeza by: 1) measuring the level of sericea lespedeza control and forb tolerance to varying rates of herbicides applied in spring and summer, 2) comparing effectiveness of summer-applied to spring-applied herbicide treatments, and 3) determining how supplemental seeding of native grasses and forbs enhance restoration success following herbicide treatment.

Native Grass Establishment Following Herbicide Applications

Native Grass Establishment Following Herbicide Applications

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.

Herbicide Application Timing Critical to Control Exotic Hawkweeds

Herbicide Application Timing Critical to Control Exotic Hawkweeds

This article summarizes field studies established on meadow hawkweed at two sites near Santa, Idaho by Dr. Tim Prather, University of Idaho. Selective herbicides such as Milestone® herbicide have shown to control hawkweeds and release grasses and desirable native forbs. Strategically timed herbicide applications can improve hawkweed control and promote establishment and maintenance of grass cover.
