多效唑、特效唑是新开发的三唑类高效低毒的植物生长延缓剂和广谱性杀菌剂。由英国帝国化学公司(ICI)和日本住友化学公司于七十年代末和八十年代初推出。1984年以来,我国江苏等省对多效唑的生物学效应进行了一系列试验,证明多效唑对于矮化水稻的作用非常显著,而且增产效果稳定。为了探讨多效唑、特效唑对稻瘟病的防治前景。我们进行了多效唑、特效唑对稻瘟病孢子的抑制作用试验。以三唑酮为对照。供试稻瘟病菌株为ZA15小种。每种药剂设6种浓度。稻瘟病孢子悬浮液(100倍显
Paclobutrazol and its derivatives are newly developed high activity and low toxicity plant growth retardants and broad spectrum fungicides. By the British Imperial Chemical Company (ICI) and Sumitomo Chemical Japan launched in the late seventies and early eighties. Since 1984, a series of experiments have been carried out on the biological effects of paclobutrazol in Jiangsu and other provinces of our country. The results showed that the effect of paclobutrazol on dwarfing rice was significant and the yield was stable. In order to investigate paclobutrazol, the effect of the oxazole on rice blast prevention and treatment. We conducted the paclobutrazol, aerobase inhibition of rice blast spores experiments. Triadimefon was used as control. The test for the blast strain ZA15 races. Each agent is set at 6 concentrations. Rice blast spore suspension (100 times significantly
