Last month, BASF announced the launch of its new herbicide, Amplexus (imazapic + imazapyr), for the management of hard-to-control weeds.
The product can also be used in effectively managing the pre-planting desiccation of soybeans and the invasion of wide and narrow-leaf weeds, most notably sourgrass (Digitaria insularis).
The product acts systematically through foliar and root absorption. According to BASF, Amplexus can be used for tolerant genetically-modified soybeans and those that are non-tolerant to imidazolinones.
According to the company, the active effects of Amplexus reduces the levels of three aliphatic amino acids with ramified chain, which are valine, leucine and isoleucine, through inhibiting hydroxyacetic acid synthetase, a common enzyme in the biosynthetic pathway of these amino acids.
“Amplexus is absorbed by leaves and roots and transported rapidly through the xylem and phloem to the meristematic regions of the plant, where it accumulates. Through interrupting growth and the death of meristematic regions, which occur straight after application, chlorosis of new leaves and necrosis of tissues can last for two weeks in some species,” BASF added.
The announcement was made during the VIII Brazilian Soybean Congress, along with the launch of the herbicide, Atectra. The event, which was organized by the Strategic Committee Soja Brasil, was held between 11st and 14th June in Goiânia, Goiás, and saw discussions on major advances and trends that could transform the farming industry in the coming years.
