Effects of monosulfuron on growth of Anabaena flosaquae
Choosing safe herbicides to blue-green algaes is important to protect ecosystem in rice fields and sustainable development of agriculture.The results of toxicity test of monosulfuron on Anabaena flosaquae showed that under the concentration of 0.75 mg·L~(-1),monosulfuron had no significant influence on cell number,dry weight,growth rate and photopigment.However,strong toxicity was detected when the concentration exceeded 7.5 mg·L~(-1),and the EC_(50) value after treated with herbicides for 72 h was 0.99 mg·L~(-1).
