Abstract: Intercropping is a crucial agroecosystem to alleviate the autotoxicity in crops. For this, 5- crops were tested for their compataibility with muskmelon. Of these, root exudates of fennel (Foeniculum valgare), onion (Allium cepa) and rape (Brassica campestris) inhibited the growth of Fusarium oxysporum f. sp. melonis, and stimulated the seed germination and seedling growth of muskmelon. Field experiments showed that muskmelon + fennel, muskmelon + onion and muskmelon + rape intercropping systems could alleviate the Fusarium wilt. Phenolics in fennel, onion and rape root exudates were detected by HPLC and the benzyl benzoate, dibutyl phthalate and p-tolyl benzoate were identified in all the 3-plants root exudates. These phenolics suppressed the growth of Fusarium oxysporum f. sp. melonis and promoted the growth and development of muskmelon.
