The guava root-knot nematode (Meloidogyne enterolobii) has become one of the greatest enemies of agricultural production as current nematode management methods are not effective against this nematode. Summer cover crops can be an alternative solution for sustainable nematode management as they have a great potential to suppress nematode reproduction in addition to providing other usual benefits. Greenhouse experiments were conducted to evaluate ten commercially available summer cover crops against M. enterolobii. Sunflower and cowpea supported a high reproduction of M. enterolobii and had significantly greater biomass relative to the susceptible control (tomato cv. Rutgers). Buckwheat and sunn hemp had lower nematode reproduction but produced greater biomass compared to the susceptible control. Sesame supported significantly lower nematode reproduction and produced the lowest biomass among all cover crops employed in this study. Three millets (pearl millet, brown top millet and Japanese millet), grain sorghum and sorghum-sudangrass did not support any nematode reproduction and produced significantly higher plant biomass when compared with the control. Results from this study suggest that the three millets, grain sorghum and sorghum-sudangrass are promising summer cover crops for managing M. enterolobii.

番石榴根结线虫（Meloidogyne enterolobii）已成为农业生产的最大敌人之一，因为目前的线虫管理方法对这种线虫无效。夏季覆盖作物可以成为可持续线虫管理的替代解决方案，因为它们除了提供其他通常的好处外，还具有抑制线虫繁殖的巨大潜力。进行温室试验以评估十种可商购的夏季覆盖作物对抗肠杆菌的情况。向日葵和豇豆支持M. enterolobii的高繁殖并且相对于易感对照（番茄 cv. Rutgers）具有显着更大的生物量。与易感对照相比，荞麦和晒麻的线虫繁殖率较低，但产生的生物量更大。在本研究中使用的所有覆盖作物中，芝麻支持显着较低的线虫繁殖并产生最低的生物量。与对照相比，三种小米（珍珠小米、褐顶小米和日本小米）、谷物高粱和高粱-苏丹草不支持任何线虫繁殖，并且产生显着更高的植物生物量。这项研究的结果表明，三种小米、谷类高粱和高粱-苏丹草是管理肠道 M. enterolobii 的有前途的夏季覆盖作物。
