Abstract:
Taking muskmelon Fusarium wilt diseased plants from Lujia Town,Sijiazi Town and Leshan Town of Jilin as material,the pathogen was isolated with the method of tissue isolation,and morphological characteristics and ITS sequence were identified,and the effects of 21 fungicides to muskmelon Fusarium wilt were studied with mycelia growth rate indoors.The results showed that seven isolates were obtained from melon wilt plants.Pathogenic test indicated that the seven separate matters had pathogenic.The pathogen of melon wilt plants was identified as Fusarium oxysporum.Prochloraz 450 g/L EC,Carbendazim 50% WP, Triflumizole 400 g/L EC,Mascot 30% WP showed better effective to melon wilt disease.Co-toxicity coefficient of Mascot 30% WP and Carbendazim 50% WP ratio by 2∶1 was the highest.The co-toxicity coefficient of Metalaxyl 30% WP and Carbendazim 50% WP by ratio of 2∶1 was followed.
