The herbicidal activity of long-acting formulations of metribuzin and tribenuron methyl herbicides embedded in granules prepared from a mixture of degradable poly(3-hydroxybutyrate) and birch wood flour was studied in laboratory-grown weeds of various species and in wheat and barley stands infested by weeds. The constructed formulations effectively suppressed all species of weeds studied. The biological effectiveness of herbicide formulations toward intact plants in wheat and barley stands infested with weeds was close to 100%, which was significantly higher than the effect of their free forms. The more effective suppression of weeds by embedded herbicides was beneficial for the growth of crops whose aboveground biomass was 8-13 to 20% greater than that of the crops in the treatments with free herbicides. Embedded metribuzin and tribenuron methyl exhibit sustained and pronounced herbicidal activity and are effective for pre-emergence soil application for crops infested with weeds of various species.
研究了将嗪草酮和苯磺隆除草剂长效制剂包埋于由可降解聚（3-羟基丁酸酯）和桦木粉混合物制备的颗粒中，对实验室培育的各种杂草以及受杂草侵害的小麦和大麦田块的除草活性。所构建的制剂有效抑制了所有研究的杂草种类。除草剂制剂对受杂草侵害的小麦和大麦田块中完整植株的生物有效性接近100%，显著高于其游离形式的效果。包埋除草剂对杂草的更有效抑制有利于作物生长，其地上生物量比使用游离除草剂处理的作物高8 - 13%至20%。包埋的嗪草酮和苯磺隆表现出持续且显著的除草活性，对受各种杂草侵害的作物进行苗前土壤施用有效。
