ForageMax~(TM) herbicide for broadleaf weeds in forage brassicas

摘要

In 2012 Dow AgroSciences submitted a registration application for ForageMax~(TM) Herbicide (50 g L~(-1) aminopyralid + 100 g L~(-1) Arylex~(TM) Active, common name halauxifen-methyl) for broadleaf weed control in forage brassicas. This product has given excellent control of key weeds including fat hen (Chenopodium album L.), capeweed (Arctotheca calendula (L.) Levyns), volunteer legumes and thistles, whilst being selective to rape and turnips, which comprise more than 70% of forage brassicas grown inAustralia. It will be registered for weed control in brassicas and is a new option for weed management in these crops. Control of these key weeds will enable farmers to maximize forage production and therefore improve profitability through increased milk or meat yields.This paper summarises new research trials, since Wells and Nott (2013) presented results, to confirm brassica (rape and turnip) selectivity, plantback (crop rotation) safety and weed efficacy on poppies (Pa-paver diibium L.), cleavers (Galium aparine L.)and shepherd's purse (Capsella bursa-pastoris (L.)
