Beware of Asian soybean rust this season

May 25, 2016

SOUTHEAST: Asian soybean rust has been found on kudzu in southwest Georgia.

This is the earliest detection of this harmful disease in Georgia crops since 2005, according to the University of Georgia Extension.

Younger beans are especially vulnerable to this disease. According to the USDA, be on the lookout for these symptoms:

  • Small lesions that increase in size and change from gray to tan, or a reddish brown
  • Lesions on the leaves, petioles, stems and pods

Syngenta recommends to continue to scout for Asian soybean rust as the season takes off. If growers suspect this disease might be present in their fields, experts suggest collecting samples and testing them as soon as possible. Additionally, utilizing fungicides can help combat this disease.

When Brazilian soybean farmers were hit with an Asian soybean rust epidemic, Syngenta researchers developed Solatenol® fungicide for broad-spectrum, long-lasting disease control. In 2014, Elatus® fungicide, containing Solatenol, proved to effectively treat Asian soybean rust in Brazil.

If Asian soybean rust is found this season, Syngenta recommends using Trivapro™ fungicide. Trivapro also contains Solatenol and is 10 times more potent than other SDHI’s on the market, delivering longer-lasting control and protection to crops.

Utilizing best agronomic practices and fungicides, when necessary, can help combat Asian soybean rust and ultimately help grow more soybeans.
