摘  要:
为了评价由新型助剂制成的草甘膦水剂的生物活性,研究建立了用空心莲子草评价草甘膦水剂的室内生测方法。以空心莲子草为生测靶标,采用喷雾法,培养介质为土壤,以地上部分鲜重抑制率为评价指标来筛选适合旱地使用的草甘膦水剂;以空心莲子草为生测靶标,采用喷雾法,培养介质为清水,以总鲜重抑制率为评价指标来筛选适合湿地或水域使用的草甘膦水剂。

摘  要:
The greenhouse bioassay method with water hyacinth was established for screening novel formulant and glyphosate AS. The bioassay target was water hyacinth(Alternanthera philoxeroides). The glyphosate AS were spraying on water hyacinth when plant height was 5-6 cm. As water hyacinth was growing at soil, fresh weight IC50 of plant above soil was evaluated for glyphosate AS used for dry land. As it was growing in water, whole weight IC50 of plant was evaluated glyphosate AS used for marsh or water region. These methods were effective to distinguish four glyphosate AS easily. It would provide good method for R & D of new formulant and glyphosate AS.
