The present study reports the herbicidal activity of metribuzin and tribenuron-methyl embedded in the degradable matrix of natural poly-3-hydroxybutyrate [P(3HB)/MET and P(3HB)/TBM]. The developed formulations were constructed as films and microgranules, which were tested against the weeds such as white sweet clover Melilotus albus and lamb's quarters Chenopodium album in the presence of soft spring wheat (Triticum aestivum, cv. Altaiskaya 70) as the subject crop for investigation. The activity was measured in laboratory scale experiments by determining the density and weight of the vegetative organs of weeds. The study was also aimed at testing the effect of the experimental formulation on the growth of wheat crop as dependent on the method of herbicide delivery. The experimental MET and TBM formulations showed pronounced herbicidal activity against the weed species used in the study. The effectiveness of the experimental formulations in inhibiting weed growth was comparable to and, sometimes, higher than that of the commercial formulations (positive control). The amount of the biomass of the wheat treated with the experimental herbicide formulations was significantly greater than that of the wheat treated with commercial formulations.
本研究报告了嗪草酮和苯磺隆嵌入天然聚-3-羟基丁酸酯（[P(3HB)/MET和P(3HB)/TBM]）可降解基质中的除草活性。所开发的制剂制成薄膜和微粒，在作为调查对象作物的软质春小麦（普通小麦，品种阿尔泰斯卡亚70）存在的情况下，针对杂草如白花草木樨和藜进行了测试。通过测定杂草营养器官的密度和重量，在实验室规模实验中测量活性。该研究还旨在测试实验制剂对小麦作物生长的影响，这取决于除草剂的施用方法。实验性的嗪草酮和苯磺隆制剂对研究中使用的杂草物种表现出显著的除草活性。实验制剂抑制杂草生长的效果与商业制剂（阳性对照）相当，有时甚至更高。用实验性除草剂制剂处理的小麦生物量显著大于用商业制剂处理的小麦。
