By Sean Gephart Noxious Weed Program Coordinator
Northern Nevada has seen heavy rainfall this spring. The extra precipitation is beneficial for our crops, rangelands and restoration efforts, but rain also increases noxious weed growth. Noxious weeds are plant species that are, or are likely to be, detrimental and destructive to Nevada’s landscape, property values and wildlife habitats. Nevada has more than 40 species of noxious weeds. Some species, like Russian knapweed, are even toxic to livestock, and many can create a deadly fuel source for wildfires. Our program coordinates resources and efforts focused on proactive prevention and control of invasive weed species to benefit all land users in Nevada.
Spring is a great time to control noxious weeds Per Nevada Revised Statute 555.130, all landowners are responsible for noxious weeds control on their property. Young weeds emerge in the spring, making it a great time to control noxious weeds. A strategy of inte-
grated weed management, combining multiple control methods, is the most effective approach. As you prepare, consider these integrated weed management recommendations.
Early detection, rapid response and consistent monitoring are key • Control methods may require multiple applications or methods in one growing season or over several growing seasons. • Plant competitive species to reduce recurrence of weeds. • Carefully follow label instructions if using pesticides. • Be patient, some weeds take multiple seasons to control. Always remember to clean your vehicle, clothes and pets if you have been in a weedinfested area. Use certified weed free forage and gravel materials to ensure you are not bringing noxious weeds onto your land.

Some species, like Black henbane, Giant reed, and Perennial Sow thistle are being moved to a different category. Some new species, like Ventenata and Flowering rush will be added to the list. These changes are pending approval by the Nevada Board of Agriculture and Legislative Council Bureau.
