A NEW contact herbicide for use in potatoes will control all the main arable broad-leaved and grass weeds up to four true leaves, including difficult weeds like cleavers, fat-hen and polygonums, according to manufacturer Bayer CropScience.
Basta (glufosinate ammonium) also provides control of seven grass weeds and 30 broad-leaved weeds making it the broadest spectrum contact option for potato growers, says Bayer's Neil Thompson.
