Exploiting typical allelopathic molecules released from the glucosinolate-myrosinase system could represent a sustainable strategy for weed management in the near future. The present study investigates the potential bioherbicidal efficacy of Eruca sativa cv. Nemat defatted seed meals (EDSM) in two independent experiments: the first one explored air release of volatile compounds (biofumigation), and the second one focused on the effectiveness of soluble compounds (soaking). Each experiment was carried out using two weed species – Silybum marianum (L.) Gaertn. (milk thistle) and Malva sylvestris L. (mallow) – and two crops frequently cultivated in the Mediterranean basin – Cynara cardunculus L. (cardoon) and Eruca sativa cv. Nemat (rocket) – as targets. The results suggested a new high-value application of EDSM with both methods on both weeds. Mallow was mainly injured by soaking, while milk thistle was mainly affected by biofumigation. An auto-toxic effect of EDSM was also noted on rocket seeds.

在选定的杂草和作物上测试Eruca sativa脱脂籽粕作为潜在的生物除草剂

利用从芥子油苷-黑芥子酶系统释放的典型化感分子可能代表在不久的将来进行杂草管理的可持续策略。本研究调查了Eruca sativa cv.的潜在生物除草功效。Nemat 在两个独立实验中脱脂种子粉 (EDSM):第一个实验探索了挥发性化合物的空气释放(生物熏蒸),第二个研究了可溶性化合物的有效性(浸泡)。每个实验都使用两种杂草 - Silybum marianum (L.) Gaertn 进行。(奶蓟)和Malva sylvestris L.(锦葵)——以及地中海盆地经常种植的两种作物——Cynara cardunculus L.(cardoon)和Eruca sativa简历。Nemat(火箭)——作为目标。结果表明 EDSM 对两种杂草都有新的高价值应用。锦葵主要受浸泡伤害,而奶蓟主要受生物熏蒸影响。还注意到 EDSM 对火箭种子的自毒作用。
