由于目前尚没有一种除草剂获得在观赏月季田块使用的农药登记证，为了探讨在观赏月季田块进行化学除草的可行性，参照 GB／T 17980．44—2000《农药田间药效试验准则（一）除草剂防治果园杂草》的方法进行了观赏月季田块杂草的化学防除试验。结果表明：高效氟吡甲禾灵、氰氟草酯2种除草剂400倍以上的稀释液对观赏月季没有药害；高效氟吡甲禾灵800倍稀释液对1年生禾本科杂草的防治效果为87．44％～91．12％；氰氟草酯800倍稀释液对1年生禾本科杂草的防治效果为80．29％～97．14％；氟磺胺草醚800倍以上稀释液对观赏月季没有药害，其800倍稀释液对观赏月季田块阔叶杂草的防治效果为83．33％～89．24％。可以看出，高效氟吡甲禾灵与氟磺胺草醚混用有降低其对1年生禾本科杂草的防治效果的趋势。

There are no herbicides approved for controlling weeds in fields of ornamental Chinese rose.To explore its fea-sibility of using chemical control against weeds in this ornamental crop,we followed the guidelines of Chinese standard GB/T 17980.44—2000 to establish a chemical control experiment.Haloxyfop -r -methyl and cyhalofop butyl diluted in more than 400 concentrations applied in the test didn’t cause phytotoxicity on ornamental Chinese rose;control effect of haloxyfop -r -methyl in 800 diluted concentrations against annual gramineous weeds was 87.44% ~91.12%,compared with that of halofop butyl in 800 diluted concentrations of 80.29% ~97.14%;fomesafen in more than 800 diluted con-centrations didn’t cause phytotoxicity on ornamental Chinese rose,and the control effect of fomesafen in 800 diluted con-centrations to broadleaf weeds in the field was 83% to 89%.From the results we can see that,mix use of haloxyfop -r -methyl and fomesafen in the field has tendency of reducing the control effect against annual gramineous weeds.
