First Report of the Yellow Nutsedge Cyst Nematode, Heterodera cyperi, in Georgia, U.S.A.

population from Spain (AF274388). COI sequence of H. cyperi showed 89% similarity (98% coverage) with that of H. guangdongensis (MF425735), and 88% similarity (83% coverage) with that of H. elachista (KC618473). The pathogenicity of H. cyperi was examined under greenhouse conditions using tobacco cv. K340, tomato cv. Tribute, cucumber cv. Thunder, and yellow nutsedge (Cyperus esculentus L.). 3-wk-old seedlings of the test plants were transferred into Deepot D25L cell containers (5-cm-diam. × 25.4-cm deep

Yellow and purple nutsedge and coffee senna as hosts of common plant nematodes in Florida

Yellow and purple nutsedges (Cyperus esculentus and C. rotundus, respectively) are among the worst weeds affecting agriculture production worldwide (Peerzada, 2017). In Florida, nutsedges are highly damaging and ubiquitous weeds in almost every agricultural and horticultural production system. Coffee senna, or coffee weed (Senna occidentalis syn. Cassia occidentalis) is a leguminous annual weed found in tropical and subtropical regions worldwide (CABI, 2016). In the United States, coffee senna

Meloidogyne aegracyperi n. sp. (Nematoda: Meloidogynidae), a root-knot nematode parasitizing yellow and purple nutsedge in New Mexico

Yellow nutsedge (Cyperus esculentus L.) and purple nutsedge (C. rotundus L.) are perennial weeds of global importance that can enhance survival and population densities of Meloidogyne incognita (Kofoid and White, 1919) Chitwood, 1949 and result in injury to crops (Schroeder et al., 1993, 1994, 2004; Thomas et al., 2004). Shoot growth of both nutsedges is not affected by M. incognita parasitism; numbers and size of reproductive tubers increase as nutrient resources are reallocated to roots, and

Grafting and Paladin Pic-21 for Nematode and Weed Management in Vegetable Production
