Abstract
[Aims] Quinclorac is widely used as a rice paddy herbicide in China, but quinclorac showed significant phytotoxicity on succeeding tobacco and there is no reliable detoxification technology, so it is urgent need of screening out the alternative agents of quinclorac. [Methods] Three kinds of herbicides bensulfuron methyl-acetochlor 22% WP,penoxsulam 25 g/L OF and bensulfuron methyl-quinclorac 38% WP chosen as alternative agents and quinclorac together were used in paddy field, the growth of weeds was investigated and production was calculated and cost was compared.[Results] The results showed that the herbicidal effect of bensulfuron methyl-acetochlor and the rice yield did not reach the same level as quinclorac, with large labor intensity, so it,s not suitable to be used as alternative agent; the control effect of bensulfuron methyl-quinclorac on paddy weed is equal to quinclorac and its rice production is also higher than that of quinclorac treatment, it can reduce the risk of quinclorac phytotoxicity, but tobacco is highly sensitive to quinclorac,so bensulfuron methyl-quinclorac also should not be used as an alternative agent. The herbicidal effect of penoxsulam and its production are superior to quinclorac and easily degrades. [Conclusions] Pcan be used as an alternative agent for weed control in rice and tobacco rotation system to solve the phytotoxicity problem of quinclorac on tobacco.
