Sorrento will help get the best out of the available herbicide chemistry. By Lucy de la Pasture Think of maize and a tall, fast-growing crop comes to mind. But early in their life maize plants are the exact opposite, leaving them vulnerable to competition from weeds until warmer conditions in late spring kick-start their rapid growth. That means weed control is the number one priority in the first few weeks after planting, says Stuart Sutherland, technical manager at Interagro. The addition of Sorrento to post-emergence herbicides can help achieve early removal of competitive weed species, particularly when conditions turn dry, says Stuart Sutherland. “Keeping the maize crop free from early weed competition is crucial to protect yield in the first month or so after emergence. Weeds can easily smother the crop, competing for light, water and nutrients.” According to the Maize Growers Associations, yields losses of up to 65% are possible where weed control is left until late in the season. “Weed competition not only leads to weak, shallow rooted plants susceptible…
