29 de jul. de 2022 · Southern root-knot nematode (SRKN, Meloidogyne incognita) is a major pest of sweet potato, and nematicides are needed to manage this nematode. The objectives of this study were to assess the efficacy of fluazaindolizine, a new non-fumigant nematicide, in comparison with the fumigant nematicide 1,3-dichloropropene (1,3-D) and non-fumigant nematicides fluopyram and oxamyl for (1) SRKN management ...
21 de jul. de 2020 · The ability of Meloidogyne enterolobii to reproduce on selected sweetpotato (Ipomoea batatas) cultivars (Beauregard, Covington, Evangeline, Hernandez, and Orleans (LA 05-111)) was evaluated in two greenhouse experiments, each with 10 replicates.All cultivars, except Beauregard (control) and Orleans, were reported previously as moderately resistant or resistant to M. incognita, Fusarium ...
11 de feb. de 2019 · Meloidogyne enterolobii (the guava root-knot nematode) is a highly polyphagous species that causes significant damage in a wide variety of crops worldwide (Castagnone-Sereno 2012). M. enterolobii has a well-documented ability to overcome many crop resistance genes that are effective against the more cosmopolitan M. incognita group (MIG) species endemic to the southern United States.
11 de abr. de 2014 · Sweet potato (Ipomoea batatas Lam.) is the fifth largest staple crop after rice, wheat, maize, and soybean in China.Sweet potato tubers were received from Zhanjiang, Guangdong Province, China, in June 2013 for research purposes. Upon inspection, the storage roots showed typical symptoms of being infected by root-knot nematodes, Meloidogyne spp.; the incidence of infection was 95%.

24 de abr. de 2023 · Meloidogyne enterolobii is an emerging species and is considered the most damaging among root-knot nematodes due to its high reproduction and ability to overcome the resistance of various crops. However, there are few studies on the differences in reproduction and pathogenicity in different populations of this species. This study aimed to morphologically and molecularly characterize M ...
Abstract. Meloidogyne enterolobii (syn. mayaguensis) is an emergent species of root-knot nematode that has become a serious threat to sweet potato (Ipomoea batatas) production in the southeastern United States. The most popular sweet potato cultivars grown in this region are highly sus-ceptible to M. enterolobii.
