Abstract:

To evaluate the impact of control measures for rice diseases, pests and weeds under the rice-fish symbiotic system on snakehead, in this study, based on the acute toxicity test method for fish in the national standard GB/T 31270.12—2014 Test Guidelines on Environmental Safety Assessment for Chemical Pesticides Part 12: Fish Acute Toxicity Test, 10 commonly used pesticides for rice diseases, pests and weeds were selected to treat snakehead under simulated field application conditions, so as to screen out the control agents that are safe and low toxicity for snakehead and have low toxicity. The research results showed that chlorantraniliprole is of low toxicity to snakehead and is suitable for promotion and application in the rice-fish symbiotic systems.

Key words: rice-fish symbiotic system, snakehead, acute toxicity, pesticide screening
