报道了单甲脒在蘑菇上的残留试验结果 .在蘑菇生产期间 ,培养料经二次发酵后 ,蘑菇菌种接种前 ,分别用单甲脒 1 .2 5 g a.i./m2和 2 .5 g a.i./m2施药处理 ,采收的鲜蘑菇中单甲脒的残留量为 0 .0 2～ 0 .86mg/kg,单甲脒在培养料中的降解半衰期 (T1 /2 )约为 9～ 1 2 d Reported the residual test results of the monoamidine in mushrooms. During the mushroom production, the culture medium after secondary fermentation, mushroom strains were inoculated with a single formamidine 1.25 g ai / m2 and 2.5 g ai / m2 application treatment, the recovery of fresh mushrooms in the monoamidine residues was 0. 02 ~ 0.86mg / kg, the degradation half-life of monoamidine in culture medium (T1 / 2) is about 9 ~ 1 2 d
