以前的研究已经证明，由酿酒酵母产生的挥发性有机化合物（VOCs）能够抑制植物病原真菌的生长。在此背景下，研究了由醇类和酯类组成的挥发性有机化合物的合成混合物的杀线虫潜力，以控制对具有高经济价值的作物造成损失的根结线虫。在最低浓度（33.3 μ L g(-1)）条件下，含挥发性有机化合物（VOCs）的底物熏蒸线虫的杀线虫效果高于30%，而在66.6和133.3 μ L g（-1）条件下，线虫死亡率为100%。本研究结果激发了线虫管理中VOCs的其他研究。
Previous studies have demonstrated that volatile organic compounds (VOCs), produced by the yeast Saccharomyces cerevisiae, were able to inhibit the development of phytopathogenic fungi. In this context, the nematicidal potential of the synthetic mixture of VOCs, constituted of alcohols and esters, was evaluated for the control of the root-knot nematode Meloidogyne javanica, which causes losses to crops of high economic value. The fumigation of substrate containing second- stage juveniles with VOCs exhibited nematicidal effect higher than 30% for the lowest concentration tested (33.3 mu L g(-1) substrate), whereas at 66.6 and 133.3 mu L g(-1) substrate, the nematode mortality was 100%. The present results stimulate other studies on VOCs for nematode management.
