Better Pesticides Contributed Greatly to Increased Rice Yields in Arkansas

Arkansas is the leading rice-producing state in the US. The average yield of Arkansas rice has steadily increased over the past twenty years. The introduction of new pesticide products, e.g., an herbicide that selectively removes weedy red rice from commercial rice without harming the crop, has played a major role in this increased yield.

“During the past 20 years, the state-average yields in Arkansas have increased approximately 1780 lb/acre (about 40 bu/acre) or 2 bu/acre/year. This increase can be attributed to improved varieties and improved management, including such things as better herbicides, fungicides, and insecticides, improved water management through precision leveling and multiple inlet poly-pipe irrigation, improved fertilizer efficiency, and increased understanding of other practices such as seeding dates and tillage practices.”
