Intra‐ and cross‐field dispersal of Beckmannia syzigachne seed by a combine harvester

Abstract: BACKGROUND Beckmannia syzigachne (Steud.) Fernald has become a dominant weed that has evolved resistance to major herbicides used in the wheat fields of rice‐wheat double cropping areas of the middle and lower reaches of the Yangtze River, China. Seed dispersal occurs over long distances via irrigation water. As mechanical harvesting services popularize, there is concern that combine harvesters could play an increasing role in B. syzigachne seed dispersal. RESULTS Random sampling of 30 combine harvesters at wh… Show more

“…The outbreak of B. syzigachne is believed to be due to its strong ability to spread and the evolution of herbicide resistance. B. syzigachne seeds have a strong floating ability, and water flow is an important way of spreading 23,24 ; in addition, with the socialization of harvesting services, harvesters have also facilitated the spread of B. syzigachne seeds 25 . With the promotion of minimum‐ and no‐tillage practices, farmers have relied increasingly on the use of herbicides to control B. syzigachne 26 …”
