Abstract
Oxaziclomefone is a new kind of systemic and conductive herbicide with a matrix of phenoxazone.It could show outstanding herbicidal characteristics,such as less application amount,long period for suitable application,and long persistent period against weeds.The experimental results indicated that the annual grassy weeds in direct seeding fields of rice,such as semen euphorbiae Leptochloa chinesis and cockspur grass Echinochloa crusgalli,as well as sedges,could be controlled effectively by 30% oxaziclomefone SC.After 45 days treatment with 30% oxaziclomefone SC at the preparation concentration of 75.0~150.0 mL/hm2,the stem control effects and the fresh weight control effects against grassy weeds were more than 85%,against sedges were 75%~85%,but the control efficiency against broad-leaved weeds was poor.These results suggested that 30% oxaziclomefone SC was applicable as a new candidate herbicide for annual grassy seeds management,such as E.crusgalli and L.chinesis,in direct seeding fields of paddy rice in South China.
