Annual bluegrass (*Poa annua*) is one of the most common and persistent weeds, found in a wide variety of agrocenoses: from industrial plantations of technical crops to berry plantings and winter wheat fields. Its ability to adapt quickly to environmental conditions and rapidly occupy vacant ecological niches creates serious threats to yield, as it competes with crop plants for nutrients, moisture, and light.
This collection of materials systematizes current data on methods of controlling this weed. Readers will find information on the species composition of weed vegetation typical for berry crops in Belarus, and will also study modern methods of grass control in beet, sunflower, and rapeseed crops using selective herbicides. In addition, the articles analyze in detail the mechanisms of resistance formation in weed plants, which is critically important for developing effective and long-term protection strategies for winter grain crops. This comprehensive approach will help specialists and private plot owners build a sound weed management system for their crops.
