本試驗目的在於評估除草劑固殺草對胡瓜園雜草之防治效果。試驗分別於桃園、台南及高雄三個試區進行。胡瓜種植後，田間雜草2-5公分時，每公頃分別以3公升及5公升之13.5%固殺草溶液（有效成分施用量為每公頃405及675克），稀釋至600公升，全面均勻噴施。對胡瓜無藥害發生，其生育及產量均不受影響，對胡瓜園之牛筋草、馬齒莧、扁穗莎草、馬唐草、滿天星、狗牙根及碎米莎草等雜草，具明顯防治效果。綜合桃園、台南及高雄三處試驗結果，在顧及經濟成本及環保考量下，胡瓜園可於種植後，田間雜草2-5公分時，每公頃施用13.5%固殺草溶液3公升，全面均勻噴施。

The experiment was conducted at three locations(Taoyuan, Tainan, Kaohsiung) to evaluate the weed control efficacy of herbicide glufosinate in cucumber field. Glufosinate was applied to 2-5 cm stage of grass at rate of 405 and 675g ai ha-1(3L and 5L ha-1 of 13.5% glufosinate) and diluted to 600L ha-1 with water respectively. The herbicide was found significantly and effectively for goosegrass(Eleusine indica (L.) Gaertn), common purslane(Portulaca oleracea L.), annual sedge(Cyperus compressus L.), crabgrass(Digitaria adscendens (H.K.B.)Henr.), sessile joyweed (Alternanthera sessilis (L.)R.Br.), bermudagrass(Cynodon dactylon(L.)Pers)and rice flat sedge(Cyperus iria L.)control. There was no herbicide injury found in cucumber. Cucumber yield was not affected by glufosinate application. According to the results and based on cost consideration, it is suggested that 13.5% glufosinate at 3.0L ha-1(405g ai ha-1)and diluted to 600L ha-1 with water can be used for weed control in cucumber field.
