The Affect Of Azoxystrobin And Difenoconazole On The Control Of Primary Diseases And The Enhancement Of The Quality

Watermelon-anthracnose and watermelon-fusarium wilt are the two most serious diseases to economic damnify. The medicaments of controlling watermelon-anthracnose are triazole germicides and some other protective germicides, but it wasn't specific medicaments to control watermelon-fusarium wilt. The study is to search the optimal mixed proportion of two kinds germicides of different function mechanism (strobilurin germicides and triazole germicides), which can prolong the using longevity of germicidal products, enhance the effect of medicaments, reduce the cost and improve the quality of farm produce. The effect of Azoxystrobin and Difenoconazole and their mix on the inhibition of the mycelial growth and the germination of the spores of Colletotrichum lagenarium and Fusarium oxysporumf.sp nveum was carried out. The results showed the mix of Azoxystrobin and Difenoconazole at the rate of 1 '.2 could take obvious effect on the inhibition. The tests in the field also expressed that the above mixture was perfect on the control of watermelon-anthracnose and watermelon fusarium wilt. The results indicated also that the mixture would be effective to enhance the quantity of sugar, Vitamin C andsoluble solid.
