Abstract

Field trials were conducted with a chitin-urea soil amendment and several other nematicides on four crop-nematode combinations: tomato-Meloidogyne incognita; potato-Meloidogyne chitwoodi; walnut-Pratylenchus vulnus; and brussels sprouts-Heterodera schachtii. Significant (P </= 0.10) nematode population reductions were obtained with the chitin-urea soil amendment in the trims on potato and walnut. In the trials on brussels sprouts and on tomato, phytotoxicity occurred at rates of 1,868 and 1,093 kg/ha, respectively. Significant (P </= 0.10) nematode reductions were also obtained with metham sodium on potato; with 1,3-D on tomato and brussels sprouts; and with sodium tetrathiocarbonate, XRM 5053, fenamiphos, ethoprop, LX1075-05, LX1075-07, and SN 109106 on tomato. The following materials did not provide significant nematode control under the conditions of the particular experiments: metham sodium, oxamyl, and Yucca extract on tomato; and dazomet granules on brussels sprouts.

摘要

采用几丁质 - 尿素土壤改良剂和其他几种杀线虫剂，对四种作物 - 线虫组合进行了田间试验，这四种组合分别是：番茄 - 南方根结线虫；马铃薯 - 奇氏根结线虫；核桃 - 穿刺短体线虫；抱子甘蓝 - 甜菜胞囊线虫。几丁质 - 尿素土壤改良剂在马铃薯和核桃试验中显著（P≤0.10）降低了线虫种群数量。在抱子甘蓝和番茄试验中，当施用量分别为1868千克/公顷和1093千克/公顷时出现了植物毒性。威百亩在马铃薯试验中也显著（P≤0.10）降低了线虫数量；1,3 - D在番茄和抱子甘蓝试验中显著降低了线虫数量；四硫代碳酸钠、XRM 5053、苯线磷、灭线磷、LX1075 - 05、LX1075 - 07和SN 109106在番茄试验中显著降低了线虫数量。在特定试验条件下，以下药剂未能有效防治线虫：番茄试验中的威百亩、杀线威和丝兰提取物；抱子甘蓝试验中的棉隆颗粒剂。
