Carbaryl application to soil collected from a rice fallow field was relatively less toxic to viable estimates of cyanobacteria and microalgae under nonflooded conditions than under flooded conditions. Application of 1-naphthol, the hydrolysis product of carbaryl, to soil under both the regimes increased the population of both cyanobacteria and microalgae. Soil application of carbaryl and 1-naphthol in combination, up to 1.0 kg ha(-1), was nontoxic to the viable population. The toxicity exerted by carbaryl and 1-naphthol towards growth, measured in terms of chlorophyll a, and nitrogenase activity was more pronounced in Anabaena spp. than in Nostoc spp.
在非淹水条件下，施用于稻田休耕土壤的甲萘威相对毒性较低，对蓝藻和微藻的活菌估算值的影响较小，而在淹水条件下则相反。在这两种条件下，将甲萘威的水解产物 1-萘酚施用于土壤会增加蓝藻和微藻的种群数量。土壤中甲萘威和 1-萘酚的组合施用（最高可达 1.0 公斤/公顷）对活菌种群没有毒性。甲萘威和 1-萘酚对生长（以叶绿素 a 衡量）和固氮酶活性的毒性在鱼腥藻属中比念珠藻属更为显著。
