Evaluation of suppressive effect of trap crops on Heterodera schachtii and Meloidogyne chitwoodi under greenhouse conditions

摘要

Two experiments were conducted in pots in a greenhouse to study the effect of green manure cultivars on the suppression of Heterodera schachtii and Meloidogyne chitwoodi. Oilradish cv. Comet showed maximum fresh shoot weight and dry root weight after eight weeks of growth. Six cultivars (Colonel, Defender, Comet, Luna, Adagio and Metex), out of seven tested, reduced cyst, egg and larval population of H. schachtii compared to fallow. Among all oil radish cultivars, the greatest reduction of M. chitwoodi population in the root was observed in Comet (98.7%) followed by Defender (94.9%).
