Bayer CropScience has received US approval for a new cereal herbicide based on established active ingredients. Huskie Complete (pyrasulfotole + thiencarbazone-methyl + bromoxynil + mefenpyr-diethyl safener) is for the post-emergence control of a range of grasses and broadleaf weeds in spring, winter and durum wheat. It is the first use of thiencarbazone-methyl in a small-grain cereal herbicide, the company points out. The company indicated last year that it was planning to combine the maize ...

BASF plans to apply for US approval for a new formulation of the herbicide, dicamba, under the Engenia brand this year. It is intended for use on Monsanto’s genetically modified dicamba-tolerant soybeans. “Engenia will be an important new tool for soybean growers battling herbicide-resistant weeds, like Palmer amaranth, waterhemp [both Amaranthus spp] and marestail [Conyza canadensis],” says Paul Rea, vice-president of BASF’s US crop protection business. Research on advances in dicamba ...

BASF has received a US label expansion for its saflufenacil (trade-marked as Kixor)-based herbicide, Sharpen, for use in rice cultivation. The pre-plant burn-down treatment is effective against broadleaf weeds, including glyphosate-resistant Palmer amaranth (Amaranthus palmeri) and marestail (Conyza canadensis), BASF points out. The company received US approval for Sharpen on maize, soybeans and other arable crops in 2009 (Agrow No 576, p 23).

The Australian Pesticides and Veterinary Medicines Authority (APVMA) has proposed the registration of Syngenta’s sulfonylurea herbicide, prosulfuron, as a new active ingredient. It would be for the post-emergence control of broadleaf weeds in turf. Prosulfuron has been sold in Europe and North America since the 1990s for use on maize and small-grain cereals. The APVMA decision is subject to a 28-day public comment period from January 17th.
