YRC2388防除稻田杂草

1997－1999年在水稻插秧田和直播田做了YRC2388防除杂草试验,结果表明,YRC2388对水稻安全,对稗草防除效果即,施药适期长,持效期长。在插秧田YRC238850％WP100－150ai.g/hm^2加农得时10％WP37．5ai.g/hm^2于稗草1－1．5叶期,或YRC2388505WP150－200ai.g/hm^2加农得时WP45ai.g/hm^2于稗草2－2．5叶期施药,在直播田YRC238850％WP150－180ai.g/hm^2加农得时10％WP37．5ai.g/hm^2于稗草1．5－2叶期,或YRC238850％WP180－225ai.g/hm^2加农得时10％WP45ai.g/hm^2于稗草2－2．5叶期施药,可有效防除稗草及阔叶杂草。     

Chloroacetanilides,oxyacetamides, tetrazolinones: mode of action. 1. Cross resistance and oleic acid incorporation in algal model systems

Results presented suggest that chloroacetamides, oxyacetamides, tetrazolinones, and possibly cafenstrole, act at the same site, although the precise molecular mode of action is still unknown, despite much research effort.
