查询词典 fungicide

The comparison test of this new methodwith spray inoculation method was conducted. The results showed the former method could increase the incidence ofdisease and uniformity than the latter one. Used cotyledon-brushing with conidial suspension and fungicide foliarspraying method, the EC 50 values of hexaconazole, myclobutanil, triadimefon, thiophanate-methyl and chlorotha lonil to Sphaerotheca fuliginea treated in different time after inoculation were determined; the results showed that 96 h was better time for disease severity evaluating.

比较了白粉病菌分生孢子悬浮液涂抹法和喷雾法接种黄瓜幼苗子叶的效果，结果表明，涂抹法发病率高，均匀度更好；测定了接菌后不同时间施药，白粉病菌对己唑醇、腈菌唑、三唑酮、甲基硫菌灵和百菌清等 5 种杀菌剂的敏感性，结果表明，接菌后 96h 施药较为敏感，测得的 EC 50 较小。

Sensitivity experiments showed that mycelial growth of the pathogen was affected by azoxystrobin,with a mean EC50as 0.964 9 μg/mL,ranging from 0.142 8 μg/mL to 1.950 9 μg/mL,and sporangial formation was affected by the fungicide to a greater extent,with a mean EC50as 0.023 9 μg/mL,ranging from 0.001 0 μg/mL to 0.084 4 μg/mL.

结果表明，嘧菌酯对辣椒疫霉的菌丝生长具有很强的抑制作用，EC50范围为0.1428～1.9509μg/mL，平均为0.9649μg/mL；对游动孢子囊形成的抑制作用更强，EC50范围为0.0010～0.0844μg/mL平均为0.0239μg/mL。

Normal distribution analysis showed that the sensitivity of these isolates to azoxystrobin was fitted well with a normal distribution function,but that of sporangial formation was not.The results suggested that,under natural conditions in Guangdong,there were some strains of capsicum blight pathogen that had resistance to the fungicide to some extent.

正态分析表明，辣椒疫病菌54个菌株菌丝生长对嘧菌酯的敏感性符合正态分布，而孢子萌发则在高浓度区具有拖尾现象，表明自然界中已存在个别具有一定耐药性的辣椒疫霉种群。

Bipolaris sorokiniana may affect turf grass to cause leaf spot, bud rot, seedling blight, root rot, sheath rot. The temperature range of colony growth is 10～40℃, the optimum 25℃. Conidia can germinate in the temperature range of 20～35℃, and germinate best at 28℃; Conidia germinate well on slide water surface, contrary to other different methods, and they can germinate well under given air condition, but germination is not strict with nutrition. The inhibiting test of 8 kinds of fungicide showed Sporgon 50WP was most effective, and the inhibiting effect of the others was well to the conidia germination.

Bipolaris sorokiniana能浸染草坪禾草叶片形成梭形病斑，并可导致芽腐、苗枯、根腐、茎基腐、鞘腐等症状；病原菌在10～40℃下能够生长，最适生长温度为25℃；病原菌分生孢子在不同萌发条件中以水平萌发较好；分生孢子萌发需要空气条件，但对营养要求不严格；在20～35℃下分生孢子均可萌发，以28℃下萌发最好；八种不同药剂对病原菌的抑制效果表明，50%施保功可湿性粉剂1500倍液效果较好，其抑菌圈直径和抑制分生孢子萌发率分别为46.2mm和81.3%，其他几种药剂对孢子萌发也有较好的抑制作用。
