摘要
试验证明 ,硫与三环唑 (7∶ 1)混配成悬浮剂 ,对抑制稻瘟菌的菌丝生长、分生孢子萌发、附着胞的形成以及产孢能力等都具有较明显的协同增效作用 ,协同作用比率 (SR)分别为 2 .1、2 .5、1.8及 8.6。混配剂集合了硫及三环唑两者的优点 ,并显示出耐雨水冲刷、持效期长的特点。田间试验亦表明其防病增产效果比较显著。
Excellent results were obtained on the control of rice blast with the sulphur tricyclazole (7:1) mixed suspension consentrate in the preliminary experimants in field plots and in extensive application . The high control efficacy was shown to be due to the inhibition effects of spore formation, germinition, appresoria formation and hyphae growth.The joint synergetic ratios ( SR ) were 2.1, 2.5, 1.8 and 8.6, respectively. It showed that the control efficacy was greatly increased by the mixture of the 2 chemicals . Because the mixture combined together the strong points of both sulphur and the tricyclazole, it was highly dispersified , suspensive, adherent and leaching resistant , and thus possessed a good residual performance.
