摘要
采用生长速率法测定了 12种农药对草坪褐斑病病原菌 (Rhizoctoniasolani)室内的抑菌效果 ,并对 8种农药以抑菌圈法和孢子萌发抑制法对草坪草离蠕孢叶枯病病原菌 (Bipolarissorokiniana )进行室内抑菌效果测定 ,并对所得结果进行方差分析。结果表明 :供试 12种农药对R .solani菌落生长抑制效果不同 ,抑菌效果达到 10 0 %的为菌核净、代森锰锌、枯腐宁 ,抑菌效果在90 %以上的为杀毒矾、粉锈宁和克露 ,百菌清的抑菌效果在 80 %以上。从 8种农药对B .sorokiniana的抑菌圈直径来看 ,它们的抑菌效果均显著差异于无药处理的对照 ,效果最好的是施保功 ,其次为百菌清和甲基托布津、百可得。 8种药剂对B .sorokiniana分生孢子萌发有较好的抑制效果 ,均达 75 %以上 ,并在同一水平上表现效果显著。
kinds of fungicides were used to test the inhibition effect on Rhizoctonia solani and 8 kinds of fungicides were used to test on Bipolaris sorokiniana, and the SPSS(Statistics Package for Social Science) was used to display the groups in homogeneous subsets, the result showed: the inhibition effect of the fungicides on the clone growing of R.solani is different, among these 12 kinds of fungicides, dimethachlor is the most effective one, mancozeb has the same effect, the inhibition effect is 100%; followed with sandofan,triadimefon and lymosanil, the inhibition effect is above 90%, and the inhibition effect of chlorotholanil is 85%.The inhibition effect of 8 kinds of fungicides on the mythelia of B.sorokiniana, is different from ck.Among these fungicides, sporgon is the best, followed with chlorotholanil, thlhiophanate-methyl and iminoctadine.The inhibition effect on the conia germinating of B.sorokiniana is above 75%.
