除草剂的可用性不断减少，成本不断增加，导致草莓种植者寻求化学和非化学替代品，特别是在草莓移植后不久进行行内杂草控制。在明尼苏达州的草莓建立几个杂草控制处理进行了检查，在2年。治疗包括：在作物行上居中的羊毛景观织物;如上，但为2层织物;当30 cm高时将春季油菜掺入土壤中;如上，但油菜用燃尽除草剂杀死并作为覆盖物留下;标准除草剂，DCPA;手工除草;且无杂草控制。种植所有草莓行之间的区域。测量包括杂草密度和重量，草莓的女儿植物的数量，和水果产量1年后移植。最好的替代处理是单层毛织物。它几乎消除了行中的杂草，促进了子代植物生根，并允许最大的果实产量，相当于DCPA和手工除草处理。油菜覆盖物控制杂草不一致，子植物和果实的产量只有中等到低。杂草控制和果实产量与掺入卡诺拉是类似的杂草检查处理。名称：DCPA;油菜，甘蓝型油菜L.;草莓（Fragaria × ananassa Duchesne 'Glooscap'）。附加索引词：覆盖作物，景观结构，杂草控制，杂草管理。
Diminishing availability and increasing costs of herbicides cause strawberry growers to seek both chemical and nonchemical alternatives, especially for within-row weed control soon after strawberries are transplanted. Several weed control treatments for strawberry establishment were examined during 2 yr in Minnesota. Treatments included: woolen landscaping fabric centered over the crop row; as above, but 2-ply fabric; spring canola incorporated into soil when 30 cm tall; as above, but canola killed with burndown herbicide and left as mulch; standard herbicide, DCPA; hand weeded; and no weed control. Areas between all strawberry rows were cultivated. Measurements included weed densities and weights, numbers of strawberry daughter plants, and fruit yield 1 yr after transplantation. The best alternative treatment was the 1-ply woolen fabric. It nearly eliminated weeds from rows, promoted daughter plant rooting, and allowed maximum fruit yields, equivalent to those of the DCPA and hand-weeded treatments. Canola mulch controlled weeds inconsistently and achieved only modest to low production of daughter plants and fruit. Weed control and fruit yield with incorporated canola were similar to the weedy check treatment. Nomenclature: DCPA; canola, Brassica napus L.; strawberry, Fragaria × ananassa Duchesne ‘Glooscap’.
