| 中文摘要: |
| 研究了10种杀真菌剂在田间使用浓度的中间浓度及其10倍稀释液下,对昆虫病原真菌块耳霉孢子萌发的影响。结果表明各杀菌剂对块耳霉孢子萌发有不同程度的抑制,浓度愈高,抑制作用愈大。多菌灵、普力克对孢子的抑制作用最小,与块耳霉表现出良好的相容性,是与块耳霉实施菌药合用的候选药剂。施保功、大生、达科宁3种杀菌剂对块耳霉孢子的杀伤力最大,在两种浓度下孢子萌发率均为0。施佳乐、速克灵和敌力脱在低浓度下,与块耳霉的相容性良好,处理后24～48 h与对照无显著性差异;但在中间浓度水平下,处理后48 h孢子萌发率分别为12.45％,0,0。其余药剂随处理时间和浓度不同,对块耳霉孢子萌发有不同程度的抑制。 |
| 英文摘要: |
| The effects of 10 fungicides on conidial germination of Conidiobolus thromboides Drechsler at two concentrations were tested. The results showed that different fungicides had different inhibition effects on conidial germination. Increasing the concentration of these fungicides resulted in increased inhibition. Carbendazim and propamocarb hydrochloride had the lowest effects on the spores of C. thromboides, suggesting a good candidate for combined use of fungicides and fungal insecticides. The effects of prochloraz manganese chloride complex, mancozeb, chlorothalonil on spore germination were the highest, and the spore germination rates were zero at two concentrations. At low concentration, pyrimethanil, procymidone, and propiconazole had good compatibility with C. thromboides 24-48 hours later, and the spore germination rates showed no significant differences with the control. But at lethal concentration of fungicides, the spore germination rates were 12.45% , 0, 0, respectively after 48 hours. Other fungicides had different inhibition effects on the spore germination at different time and concentrations. |
