ABSTRACT Environmental conditions can influence herbicide metabolism and interfere with the evolution of weed resistance. This study aimed to evaluate effect thermal regimes on control barnyardgrass (Echinochloa crus-galli) susceptible resistant herbicides imidazolinones chemical group. Factor A (biotypes) consisted one biotype that is imazethapyr; factor B (dose) comprised six imazethapyr dose...

6-Methoxy-2-benzoxazolinone (MBOA) is an allelochemical that found in Poaceae and generally associated with monocotyledon species. This compound formed from the glycosylated form of 2,4-dihydroxy-(2H)-1,4-benzoxazin-3(4H)-one (Gly-DIMBOA) by a two-stage degradation process. The MBOA detoxification capacity two weed species, namely Echinochloa crus-galli Lolium rigidum, resistant biotype rigidum...
