【摘要】 <正>唑菌酯(试验代号:SYP-3343)是沈阳化工研究研制开发的又一strobilurin类杀菌剂,前期研究显示其在离体和活体上都表现对Phyriculariagrisea出色的防治效果,并且优于对照的商品化药剂。本研究发现唑菌酯对Phyriculariagrisea菌丝生长、菌丝形态、孢子萌发、芽管伸长、附着孢形成、附更多还原

【Abstract】 SYP-3343 is a strobilurin fungicide developed by Shenyang Research Institute of Chemical Industry, early in vitro and in vivo study revealed that, it had good effecacy against Phyricularia grisea better than that of commercial fungicides did. In this study, SYP-3343 showed obvious effects on mycelium growth, mycelium form, spore germination, tube elongation, appressorium formation, appressorium penetration and spore production. SYP-3343 had also better effecacy against Phyricularia grisea with protective, curative and eradicant action than that of azoxystrobin, propiconazole and tricyclazole did. SYP-3343 could not be absorbed by rice root, but could be uptook by rice leaf and transported in phloem and xylem.更多还原
