Synergistic Activity of SYP-Z048 Mixing with Thiram Against Botrytis cinerea

A synergistic combination of thiram and SYP-Z048 (5:1) has been selected using the mycelial growth rate tests on the Botrytis cinerea strains from different regions of Baoding and Chengde.The effects of the combination of thiram and SYP-Z048 on the spore germination rate,the inhibitory activity of sclerotia,and the contents of the mycelium content has also been studied.The 5:1 combination showed significant inhibitory effects on the spore germination,emergence and germination of sclerotia and soluble sugar,soluble protein content is significant,in contrast with the control and the compound used alone.The inhibitory effects of 5:1 combination on lesion diameters,infection rates and spore germination rates was significantly better than that in control and single compound used alone.To sum up,the combination of thiram and SYP-Z048 has a synergistic inhibitory activity on Botrytis cinerea.
