Acquisition history (selection) The following is an illustration of the company's mergers, acquisitions, spin-offs and historical predecessors: Products and services Syngenta has eight primary product lines which it develops, markets and sells worldwide; Its five product lines for pesticides are selective herbicides, non-selective herbicides, fungicides, insecticides and seed care. Three product lines for seed products include corn and soya, other field crops and vegetables. In 2014, sales from crop protection products accounted for US $11.381 billion, i.e. 75% of total sales. Field crop seeds include both hybrid seeds and genetically engineered seeds, some of which enter the food chain and become part of genetically modified food. According to Syngenta, in the US their "proprietary triple stack corn seeds expanded to represent around 25 percent of units sold." In 2010, the US EPA approved insecticidal trait stacks including Syngenta's AGRISURE VIPTERA™ gene, which offers resistance to certain corn pests. Syngenta cross-licenses its proprietary genes with Dow AgroSciences and thus is able to include Dow's Herculex I and Herculex RW insect resistance traits in its seeds. It sells a VMAX soybean that is resistant to glyphosate herbicide.
