Quadris Fungicide Applied Early Program Achieves Additional Value

Greensboro, North Carolina (March 10, 2011)–Syngenta Crop Protection unveiled an innovative corn fungicide program in the 2010 growing season, focusing on fungicides applied in the early vegetative stages to obtain preventive disease control and Plant Performance™ benefits.


“Quadris® fungicide applied to corn in its early vegetative growth stage (V5) provides growers additional value,” said Eric Tedford, fungicide technical brand manager, Syngenta Crop Protection. “In on-farm trials in 2010, growers across the South and the Midwest saw less disease, greener plants and larger yields, an average of 6 bushels per acre in the corn plots treated with Quadris fungicide at the V5 growth stage relative to the untreated plots.”

Early-season applications of Quadris provide preventive disease control and enhanced Plant Performance while the corn leaf and ear shoots are being determined at the early vegetative stages. “The Plant Performance benefits provided by Quadris are tangible,” said Tedford. “Syngenta announced the development of azoxystrobin in 1992, and we’ve researched the physiological benefits ever since. Applying Quadris during these key stages of development helps the corn plant improve growth, increase water use efficiency and preserve green leaf area. This all breaks down to a simple concept: allowing the corn plant to utilize more energy to produce bigger ears and more kernels around. Essentially, we allow plants a better opportunity to reach their full genetic yield potential.”

Growers also see the value of an early fungicide application being more than simply disease control. “There were a lot of physical differences between the Quadris-treated at V5 corn and the untreated corn,” said Charlie Cobb, a grower from Montgomery City, Mo. “On the Quadris-treated corn, the leaves stayed greener throughout the season, and the leaf tissue on the Quadris-treated corn was a lot better quality and a lot healthier. The stalks looked better as well, which is important because if you’ve got a bad stalk, it will interrupt the natural drying down process of the corn.”

The early fungicide application program will continue to expand in the 2011 season. For additional insight from the growers and retailers who tried the early application in 2010, visit the FarmAssist® website to view video comments.
