Since the 2005 ban of methyl boiler by federal regulators, winter birthmark growers accept had bound options for managing broadleaf weeds, grasses and nutsedge species. But new analysis featured in the account Edger Technology shows drip-applied herbicides may advice to ample the gap.
Scientists at the University of Florida’s Gulf Coast Analysis and Education Center conducted acreage abstracts to appraise seven herbicides activated through dribble irrigation, including EPTC, flumioxazin, fomesafen, halosulfuron, napropamide, oxyfluorfen and S-metolachlor. Each was activated one to two weeks afore birthmark plants were crude into beds covered with polyethylene mulch. Researchers again evaluated edger ascendancy capability and how able-bodied birthmark plants acceptable the herbicides.
EPTC, fomesafen and napropamide were begin to be able at suppressing chicken nutsedge, while flumioxazin, fomesafen and halosulfuron were able at suppressing atramentous medic. Unfortunately, none of the drip-applied herbicides abundantly suppressed Carolina geranium.
Researchers begin that halosulfuron was the alone herbicide to aftermath cogent abrasion to birthmark plants. They additionally bent there was no abridgement in absolute drupe crop from any of the herbicides in the study, including halosulfuron.
“Our allegation advance that the appropriate drip-applied herbicides administered aing to the displace date can be a safe and accessible basic of edger ascendancy in winter birthmark crops,” says Nathan Boyd, accessory assistant at the University of Florida. “Drip appliance can move herbicides afterpiece to the edger basis area for bigger ascendancy results, while abbreviation appliance risks and alluvion concerns.”
