Monsanto is the maker of Roundup.
The combined company would become the largest supplier of farm chemicals and seeds, according to the report.
Monsanto's stock was up about 17% in premarket trading, after surging as much as 20%.
Monsanto, which has a market cap of about $40 billion, is the maker of the pesiticide Roundup.
The news follows a couple of other major deals in the agrochemicals space.
The Chinese chemical giant ChemChina in February agreed to buy the Swiss seed-maker Syngenta for $43 billion. In December, Dow Chemical and DuPont announed a $130 billion deal to combine forces.
