Plant defense elicitors are valuable tools in sustainable agriculture, providing an environmentally friendly and effective means of enhancing plant defense and promoting plant health. Fusarium head blight (FHB) is one of the most important fungal diseases of cereal crops worldwide. The PSP1 is a novel biopesticide formulated based on an elicitor, the extracellular protein AsES, from the fungus Sarocladium strictum. The present work aimed to evaluate the effectiveness of PSP1 in controlling FHB under field conditions. Experiments were conducted during three consecutive growing seasons (2019, 2020, and 2021). Three biostimulant treatments were tested in different physiological stages (from late tillering to heading stage), and FHB inoculations were performed at anthesis. Disease parameters, seed parameters, grain yield, and grain quality parameters were evaluated.

PSP1 生物刺激剂对禾谷镰刀菌-小麦病理系统的评价：对疾病参数、谷物产量和谷物品质的影响

植物防御诱导子是可持续农业中的宝贵工具，为增强植物防御和促进植物健康提供了一种环保且有效的手段。赤霉病（FHB）是全世界谷类作物最重要的真菌病害之一。 PSP1 是一种新型生物农药，基于来自真菌Sarocladium strictum的激发子（细胞外蛋白 AsES）配制。目前的工作旨在评估 PSP1 在现场条件下控制 FHB 的有效性。实验在连续三个生长季节（2019 年、2020 年和 2021 年）进行。在不同生理阶段（分蘖末期至抽穗期）试验了三种生物刺激剂处理，并在花期接种FHB。评估了疾病参数、种子参数、谷物产量和谷物质量参数。
