人工模拟杀菌剂银泰对10种植物病原菌的室内生物测定

A Bioassay of Yintai (An Artificial Synthetic Fungicide) on Ten Kinds of Pathogens of Plant Disease

室内生测结果表明，拟银杏杀菌剂银泰对苹果腐烂病菌、苹果干腐病菌、葡萄黑豆病菌、番茄灰霉病菌、小麦纹枯病菌及玉米大斑病均具有显著的抑制作用。ＥＣ５０分别为２３．６３μｌ·Ｌ－１、５６．３６μｌ·Ｌ－１、６２．１９μｌ·Ｌ－１、４０．６９μｌ·Ｌ－１、３６．１１μｌ·Ｌ－１、２５．０１μｌ·Ｌ－１；ＥＣ９５分别为９３．３７μｌ·Ｌ－１、６０８．８９μｌ·Ｌ－１、２５２．８７μｌ·Ｌ－１、２８９．８９μｌ·Ｌ－１、９７．６６μｌ·Ｌ－１、２０６．２７μｌ·Ｌ－１，对其余４种病原菌也具有一定的抑菌作用。

Yintai is a kind of new synthesized fungicide according to the simulation of the structure of active compound in Gingko (Gingko biloba L.). The result of bioassay showed that Yintai had obvious inhibitory effect on the pathogens of valsa mali Miyabe et Yamada, Botryosphaeria dothidea (Moug. et Fr.) Ces et de Not, Sphaceloma ampelinum de Bary, Botrytis cinerea Pers.,Rhizoctonia cerealis V.Hoeven, Drechslera turcica (pass) Subram et Jain. The EC 50 of Yintai to the pathogens mentioned above were 23.63μl·L -1 、 56.36μl·L -1 、 62.19μl·L -1 、 40.69μl·L -1 、 36.11μl·L -1 、 25.01μl·L -1 ; respectively, and EC 95 were 93.37μl·L -1 、608.89μl·L -1 、252.87μl·L -1 、289.89μl·L -1 、97.66μl·L -1 、206.27μl·L -1 ,respectively.Yintai had certain inhibitory effect to other 4 kinds plant disease pathogens.
