Abstract: 【Objective】To screen out safe and efficient soil-applied herbicides suitable for chickpea field.【Methods】To select 12 commonly-used herbicides in production for field soil experiments,use absolute value survey method to evaluate the weeding effect of each herbicide,and analyze the safety of each herbicide on chickpea under experimental doses.【Results】Every treatment had good soil sealing effect on broadleaf weeds in chickpea field,with the plant control efficacy ranging from 93.85% to 100% and the fresh weight control efficacy ranging from 87.80% to 100% at 45 days after application. However,there were some differences of control effect on gramineous weeds among these different treatments. 330 g/L pendimethalin EC,50% acetochlor EC,50% napropamide WDG,960 g/L S-metolachlor EC and 40% pyroxasulfone SC were safe to chickpea and could effectively control the gramineous weeds in chickpea fields,with the plant control efficacy ranging from 95.19% to 100% and the fresh weight control efficacy ranging from 99.13% to 100% after 45 days,42% fluridone SC,65% prodiamine WDG,480 g/L trifluralin EC,240 g/L oxyfluorfen EC and 250 g/L oxadiazon EC also had good control effect on gramineous weeds,with the plant control efficacy ranging from 96.58% to 100%. The fresh weight control efficacy of these five herbicides except 240 g/L oxyfluorfen EC was ranged from 88.24% to 100% after 45 days. However,these five kinds of herbicides exhibited different degree of phytotoxicity to chickpea,which could gradually ease with the growth of chickpea. 50% prometryn WP and 51% flumioxazin WDG could seal gramineous weeds to a certain extent,but the persistence was relatively short and 50% prometryn WP had obvious phytotoxicity.【Conclusion】Based on comprehensive consideration of control effect and crop safety,330 g/L pendimethalin EC,50% acetochlor EC,50% napropamide WDG,960 g/L S-metolachlor EC and 40% pyroxasulfone SC were suitable for soil-applied herbicide chickpea field.
