實(shí)施例3
盆栽法除草活性抑制實(shí)驗(yàn)
本專(zhuān)利采用苘麻、刺莧和藜為代表性雙子葉植物靶標(biāo),采用溫室盆栽法對(duì)本專(zhuān)利所合成的部分目標(biāo)化合物進(jìn)行了除草活性測(cè)試。
試驗(yàn)藥劑:用分析天平稱(chēng)取原藥,加乳化劑(吐溫-80)和溶劑(DMF或DMSO或水),配制成1.0~5.0%的乳油小制劑或水劑。然后用蒸溜水稀釋成10g/畝濃度備用。
試驗(yàn)方法:將供試雜草種子均勻播入內(nèi)徑9cm盆缽中,于溫室中培養(yǎng)。待雙子葉雜草真葉期時(shí),在自動(dòng)噴霧裝置上進(jìn)行芽后莖葉噴霧處理。每處理3次重復(fù),設(shè)空白對(duì)照,處理后靜置4~5小時(shí),待葉片上藥液干后,移入溫室內(nèi)培養(yǎng)。每天觀察植株生長(zhǎng)情況,定期記錄受害癥狀,分別于藥后25天目測(cè)調(diào)查綜合除草活性。
評(píng)價(jià)標(biāo)準(zhǔn):結(jié)果調(diào)查采用目測(cè)法,目測(cè)評(píng)價(jià)藥劑對(duì)植株生長(zhǎng)抑制、畸形、黃化、腐爛、壞死等影響程度,然后根據(jù)綜合受害程度按0~100%分級(jí)法目測(cè)評(píng)價(jià)除草活性。評(píng)價(jià)標(biāo)準(zhǔn)具體見(jiàn)表1。
