研究了5种土壤藻类对4-氨基-6-叔丁基-3-（甲基硫）-as-triazin-5 (4H)one （metrizin）及其6-异丙基和6-环己基类似物的体外生长响应。采用0.05、0.1、0.5和1.0 ppm （w/v）浓度的液体营养液对小球藻、绿球藻、衣藻和水藻进行除草剂处理，并在土壤中对一种裂菌进行相同浓度的除草剂处理。除了一个例外，所有藻类的生长和数量都因除草剂浓度的增加而显著降低。0.05 ppm的环己基类似物对水藻没有影响。在1.0 ppm浓度下，任何一种除草剂都不允许生长。小球藻和衣藻在0.5 ppm的吡虫嗪或环己基类似物的存在下不能生长。不同物种对三嗪酮的反应存在差异。其中衣藻最敏感，水藻和小球藻最耐药。
Growth response of five species of soil algae to 4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5 (4H)one (metribuzin) and its 6-isopropyl and 6-cyclohexyl analogs were studied in vitro. Species of Chlorella, Chlorococcum, Chlamydomonas, and Anabaena were exposed to 0.05, 0.1, 0.5, and 1.0 ppm (w/v) of the herbicides in liquid nutrient, while a species of Schizothrix was studied at the same levels in soil culture. With one exception, the growth and numbers of all of the algae were significantly reduced by increasing herbicide concentrations. Anabaena was not affected by 0.05 ppm of the cyclohexyl analog. No growth was permitted by any of the herbicides at 1.0 ppm. Chlorella and Chlamydomonas could not grow in the presence of 0.5 ppm of metribuzin or the cyclohexyl analog. Differences in response to the triazinones were noted between species. Chlamydomonas was the most sensitive and Anabaena and Chlorella the most resistant.
