Recently, at the Soybean Innovation Club held in Mato Grosso, Brazil, Bayer revealed to AgroPages that it is developing a series of herbicide solutions to deal with the increasingly serious problem of weed resistance.
It is reported that Bayer's solution covers the entire production cycle from before the germination of invasive weeds to before the soybean harvest. Contains 11 solutions at different stages designed to control the spread of resistant weeds in crops such as soybeans, corn, cotton and sugarcane. It contains the new product Convintro Duo (flupyram + mesotrione) that Bayer plans to launch in 2026. This product is specially used for weed control before soybean germination.
Bayer said it will also launch products containing icafolin-methyl, a new compound targeting post-emergent weeds, in the coming years, the first such new molecule to be developed in 30 years. Icafolin is a new isoxazole herbicide from Bayer CropScience. It was officially approved by ISO in August 2023 and will play a key role in weed management, especially the control of crabgrass and goosegrass.
Bayer's current strategy is to use combinations of active ingredients in most new products. Data show that Brazil currently has more than 44 million hectares of soybean planting area, and about 60% of weeds have developed resistance to at least one existing active ingredient. It is expected that by 2030, this proportion may exceed 65% of the oilseed crop area, and more weeds will appear that are resistant to multiple active ingredients at the same time. In response to this trend, Bayer proposed to develop a new weed management system that no longer simply targets a single crop, but considers a crop rotation system. For example, weed control of the next crop of soybeans begins after the corn is harvested to reduce weed invasion and improve the control effect.
In addition, following RR soybeans, Intacta RR2 Pro and Intacta2 Xtend, Bayer announced that it is developing fourth-generation genetically modified soybeans that will be tolerant to four herbicides and provide new pest control modes.
