氟酮磺隆对小麦田禾本科杂草的活性

Efficacy of flucarbazone against grass weeds in wheat

氟酮磺隆作为土壤处理剂,能有效的抑制看麦娘、野燕麦、雀麦,对节节麦也有一定抑制作用;作为茎叶处理剂,对麦田禾本科杂草的活性随着叶龄增加而降低,在看麦娘、野燕麦和雀麦3叶期以前和节节麦1.5叶期以前使用的除草效果好。对照药剂精唑禾草灵无土壤处理活性,苗后茎叶处理对雀麦和节节麦也无明显活性。

Flucarbazone is a soil-applied herbicide, providing effective inhibition of goatgrass, shortawn foxtail, and wild oats, along with suppression of Japanese bromegrass. When used as a foliar treatment, flucarbazone efficacy decreases as grass leaf stage increases, providing good control of shortawn foxtail, wild oats, and Japanese bromegrass before the 3-leaf stage and of goatgrass before the 1.5-leaf stage. The commercial standard herbicide fenoxaprop-P had no soil activity and provided inadequate postemergence control of Japanese bromegrass and goatgrass.
