【摘要】 可湿性粉剂是生物农药的重要剂型。通过平板培养法,测定菌落形成单位数(cfu值),开展了可湿性粉剂多种常用助剂对高效生防真菌粉红粘帚霉67-1菌株孢子的生物学相容性研究。所试载体中,滑石粉等4种处理与对照没有显著性的差异,对粘帚霉孢子活力影响不明显;所试润湿分散剂中,木质素磺酸钙与对照没有显著性差异,对粘帚霉孢子活力影响不明显;所试紫外保护剂均对孢子活力无显著影响,但在紫外灯照射3min的条件下,只有腐植酸和糊精能有效保护孢子活力;常用稳定剂CMC-Na(羧甲基纤维素钠)对孢子活力无影响。上述多种与粘帚霉孢子具良好生物学相容性助剂的确定,为粘帚霉可湿性粉剂的研究提供重要依据。更多还原

【Abstract】 We studied the influence of some wettable power adjuvants on the vigor of spore of Gliocladium roseum 67-1 that could parasite and destroy many plant pathogenic fungi effectively and was isolated by plate culturing and clones counting method. Results indicated that 4 carriers, calcium lignin sulfonate as a wetting dispersant, CMC-Na as a stabilizer, humic acid and dextrin as UV protectants showed favorable biological compatibility to the spore of Gliocladium roseum 67-1 and suited for the preparation of the Gliocladium wettable power.更多还原
