Soil treatments with formulated plant biomasses or waste materials can be an effective alternative to green manure crops for a sustainable management of root-knot nematode infestations. The suppressive performance of soil amendments with three commercial formulations of defatted seed meal from , dry biomass of and pressed pulp from was comparatively evaluated on the root knot nematode both on potted and field tomato (cv. Regina) trials. Products were applied at rates of 10, 20, 30 or 40 g/kg and 20 and 40 T/ ha soil in pots and field, respectively. Soil non treated or treated with the nematicide Oxamyl were used as controls in both experiments. Amendments in potted soil significantly reduced infestation on tomato roots compared to both the untreated control and treatment with Oxamyl, also increasing tomato plant growth up to the 30 g/kg soil rate. At the end of the field tomato crop, soil population density of resulted significantly reduced by all the tested treatments, whereas tomato yield was significantly higher than the untreated control only at the lowest amendment rate. Soil amendments with the materials tested in this study demonstrated to be a potential additional tool for a satisfactory and safe management of root-knot nematodes.
用配方植物生物质或废料进行土壤处理，对于根结线虫侵染的可持续管理而言，可能是绿肥作物的一种有效替代方法。在盆栽和田间番茄（品种为Regina）试验中，比较评估了用三种来自[具体植物名称1]的脱脂种子粕商业配方、[具体植物名称2]的干燥生物质以及[具体植物名称3]的压榨果肉进行土壤改良对根结线虫的抑制性能。产品分别以10、20、30或40克/千克的用量施用于盆栽土壤，以20和40吨/公顷的用量施用于田间土壤。在两个试验中，未处理的土壤或用杀线虫剂草肟威处理的土壤用作对照。与未处理的对照和用草肟威处理相比，盆栽土壤中的改良剂显著降低了番茄根上的[根结线虫名称]侵染，在土壤用量达到30克/千克时还促进了番茄植株生长。在田间番茄作物收获结束时，所有测试处理均使[根结线虫名称]的土壤种群密度显著降低，而仅在最低改良剂用量时，番茄产量显著高于未处理的对照。本研究中测试的材料进行土壤改良，证明是一种令人满意且安全地管理根结线虫的潜在额外工具。
