Management of Hoplolaimus columbus with Tolerant Soybean and Nematicides.
نویسندگان
چکیده
Two experiments, one site per year, were conducted in Scotland County, North Carolina, to determine the usefulness of selected cultivars and nematicides for limiting soybean losses due to Hoplolaimus columbus. Coker 317 was relatively tolerant to this nematode, and Coker 156, Centennial, Dehapine 105, and Gordon were generally intolerant. Most nematicides significantly increased soybean yields, and many gave an economic return.

Control of Hoplolaimus columbus on Late-planted Soybean with Aldicarb.
Efficacy of three rates of aldicarb for control of Hoplolaimus columbus was evaluated on highly tolerant ('Foster'), moderately tolerant ('Coker 368'), and highly susceptible ('Braxton') soybean cultivars planted on 28 June 1985. Average yields of the nontreated cultivars were 557 kg/ha for Braxton, 1,309 kg/ha for Coker 368, and 1,682 kg/ha for Foster. Yield differences were significant. Aldic...
متن کاملHost-parasite relationships of Hoplolaimus columbus on Cotton and soybean.
Hoplolaimus columbus suppressed growth and pod yield of soybean in greenhouse tests. Although populations of H. columbus decreased in short-term experiments, increases occurred in long-term studies. The nematode caused extensive damage to the cortical parenchyma and occasionally to the endodermal-vascular region of both cotton and soybean roots. The nematode frequently entered secondary root pr...

Yields of 'McNair 800' soybeans, Glycine max (L.) Merr., were significantly increased with ethylene dibromide + chloropicrin, DBCP, phenamiphos, and aldicarb applied at-planting and with phenamiphos, aldicarb, and DBCP applied postplant to soil infested with Meloidogyne incognita (Kofoid and White) Chitwood. Yields of 'GaSoy 17' were significantly increased with ethylene dibromide + chloropicri...

متن کاملChemical Control of Hoplolaimus columbus on Cotton and Soybean.
Seven experiments, three on soybean and four on cotton, were conducted in Hoplolaimus columbus-infested soil in southern North Carolina to determine the benefits of chemical soil treatment. Locations were selected to give a range of initial population (Pi) densities. Soil fumigation with 1,3-D and soil treatment with a combination of aldicarb plus fenamiphos (1.1 kg a.i./ha) each provided good ...
