Subsequent hand-weeding is usually carried out 2 months after planting and again after 5 months, but in Colombia the use of the herbicide linuron at the rate of 0.75 kg/ha has been found to give excellent control over broad-leaved weeds if applied 40-50 days after planting.
Chemical control gives excellent results: pre-emergence application of, for example, linuron or diuron with subsequent application of shielded sprays of paraquat, has proved successful.
Afalon (linuron) are both welcome additions to a previously limited and expensive armoury.
Lorox (linuron) and Sencor (metribuzin) have been available for more than 25 years, but still have good soil-residual activity on a variety of weeds including glyphosate and ALS-resistant pigweed when applied behind the planter and activated by rainfall or overhead irrigation.
The Commission's proposals, according to the Pesticides Safety Directorate analysis, would also remove linuron, pendimethalin and metribuzin, leaving few chemical options, she said.
