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。

表1 除草活性目測(cè)法評(píng)價(jià)標(biāo)準(zhǔn)

衍生物對(duì)雙子葉植物的盆栽除草活性數(shù)據(jù)詳見(jiàn)以下表2:

表2 部分化合物I對(duì)雙子葉植物的除草活性(盆栽法)

上述研究結(jié)果表明,在母體骨架中引入有機(jī)銨鹽而得到的結(jié)構(gòu)骨架I顯示了高效的除草活性。例如化合物7、13、15、31其除草活性均高于相應(yīng)的金屬鉀鹽、鈉鹽、鋰鹽。特別是化合物7在150gai/ha劑量下對(duì)苘麻、刺莧和藜的防效為100%,而且當(dāng)劑量降低8倍,在18.75g ai/ha劑量下對(duì)苘麻、刺莧和藜的抑制率也為60-80%,因此,具有通式I的化合物具有進(jìn)一步研究和開(kāi)發(fā)的價(jià)值。

本發(fā)明的化合物作為除草劑使用時(shí),可將本發(fā)明的化合物與其它植保上允許的載體或稀釋劑混合,借此將其調(diào)制成通常使用的各種劑型,如混劑、顆粒劑、水乳劑等來(lái)使用,也可以與其它農(nóng)藥如殺菌劑、殺蟲(chóng)劑、除草劑、植物生長(zhǎng)調(diào)節(jié)劑等混合使用或同時(shí)并用。

在本說(shuō)明書(shū)的描述中,參考術(shù)語(yǔ)“一個(gè)實(shí)施例”、“一些實(shí)施例”、“示例”、“具體示例”、或“一些示例”等的描述意指結(jié)合該實(shí)施例或示例描述的具體特征、結(jié)構(gòu)、材料或者特點(diǎn)包含于本發(fā)明的至少一個(gè)實(shí)施例或示例中。在本說(shuō)明書(shū)中,對(duì)上述術(shù)語(yǔ)的示意性表述不必須針對(duì)的是相同的實(shí)施例或示例。而且,描述的具體特征、結(jié)構(gòu)、材料或者特點(diǎn)可以在任一個(gè)或多個(gè)實(shí)施例或示例中以合適的方式結(jié)合。此外,在不相互矛盾的情況下,本領(lǐng)域的技術(shù)人員可以將本說(shuō)明書(shū)中描述的不同實(shí)施例或示例以及不同實(shí)施例或示例的特征進(jìn)行結(jié)合和組合。

盡管上面已經(jīng)示出和描述了本發(fā)明的實(shí)施例,可以理解的是,上述實(shí)施例是示例性的,不能理解為對(duì)本發(fā)明的限制,本領(lǐng)域的普通技術(shù)人員在本發(fā)明的范圍內(nèi)可以對(duì)上述實(shí)施例進(jìn)行變化、修改、替換和變型。
