化感覆盖作物是利用化感作用控制杂草和减少合成除草剂投入的最有前景的应用之一。采用植物箱法对53种覆盖作物（豆科26种，禾本科19种，其它8种）的化感活性进行了评价。结果表明，豆科覆盖作物如毛豌豆（Vicia villosa）和绒豆（Mucuna pruriens），禾本科覆盖作物如燕麦（Avena sativa）和黑麦（Secale cereale），某些品种的小麦（Triticum aestivum）和大麦（Hordeum vulgare）是有前途的。通过生测筛选，选出23个种进行田间试验。秋播覆盖作物，如毛豌豆，黑麦，小麦，燕麦，草豌豆，芥菜是更有效的春播覆盖作物相比。毛野豌豆是最有希望的杂草控制在废弃的领域，因为它的能力，死在夏季，使厚厚的稻草一样覆盖。
Allelopathic cover crops are one of the most promising application of allelopathy for weed control and reduce the synthetic herbicides input. Fifty-three cover crop plant species (26 leguminous, 19 graminaceous and 8 others) were assessed for allelopathic activity using the Plant Box Method. It was found that leguminous cover crops such as hairy vetch (Vicia villosa) and velvetbean (Mucuna pruriens), graminaceous cover crops, such as oat (Avena sativa) and rye (Secale cereale), certain cultivars of wheat (Triticum aestivum) and barley (Hordeum vulgare) were promising. By bioassay screening, 23 species were selected for field tests. Fall-sown cover crops such as hairy vetch, rye, wheat, oat, grass pea, and mustard were more effective when compared to spring-sown cover crops. Hairy vetch was most promising for weed control in abandoned fields because of its ability to die off during the summer season to make a thick straw-like mulch.
