摘要
１９９５年盆钵测定表明，威灵（唑禾草灵，ｆｅｎｏｘａｐｒｏｐ－ｅｔｈｙｌ）加“８８５”助剂对防除４～６叶期千金子有增效作用。每公顷用威灵５２．５克（有效成分，下同）加“８８５”有效量１４９．２５克，或威灵４５克加“８８５”２２３．９克，对４～６叶期千金子防效１００％。威灵单用，９０克时对４～６叶期千金子防效可达１００％。威灵用量下降５０％左右。加“８８５”２２３．９克最佳。防除４叶以下稗草，以威灵每３０克加“８８５”２２３．９克为宜。讨论了威灵＋８８５助剂对水稻秧苗的安全性。
he experiment was conducted in greenhouse to test the synergism of Adjuvent 885 to fenoxapropethyl in the control of 4～6 leaf stage Leptochloa chinensis and 4-leaf stage Echinochloa crusgalli.Fenoxaprop-ethyl 52.5g/ha+Adjuvent 885 149.25g/ha (or 45g+223.9g/ha) gave the best results for controlling L. chinen5.5,the control effect was similar to that of fenoxaprop-ethyl 90g/ha by itself. Fenoxapropethyl 35g/ha+Adjuvent 885 223. 9g/ha can be used to control E. crusgalli. The safety of the mixture of fenoxaprop-ethyl+Adjuvent+885 to rice psant was discussed in this paper.
