Slow-release fungicide formulations (azoxystrobin, epoxiconazole, and tebuconazole) shaped as pellets and granules in a matrix of biodegradable poly(3-hydroxybutyrate) and natural fillers (clay, wood flour, and peat) were constructed. Infrared spectroscopy showed no formation of chemical bonds between components in the experimental formulations. The formulations of pesticides had antifungal activity against . A study of biodegradation of the experimental fungicide formulations in the soil showed that the degradation process was mainly influenced by the type of formulation without significant influence of the type of filler. More active destruction of the granules led to a more rapid accumulation of fungicides in the soil. The content of fungicides present in the soil as a result of degradation of the formulations and fungicide release was determined by their solubility. Thus, all formulations are able to function in the soil for a long time, ensuring gradual and sustained delivery of fungicides.
研制了以可生物降解的聚（3-羟基丁酸酯）和天然填料（粘土、木粉和泥炭）为基质的丸粒和颗粒状的缓慢释放型杀菌剂制剂（嘧菌酯、咯菌腈和戊唑醇）。红外光谱分析表明，实验制剂的成分之间没有形成化学键。这些农药制剂对 具有抗真菌活性。研究表明，在土壤中，实验性杀菌剂制剂的生物降解过程主要受制剂类型的影响，而填料类型的影响不明显。颗粒的更活跃破坏导致土壤中杀菌剂更快速地积累。土壤中由于制剂降解和杀菌剂释放而存在的杀菌剂含量取决于它们的溶解度。因此，所有制剂都能够在土壤中长时间发挥作用，确保杀菌剂的逐步和持续释放。
