Battle soybean diseases with these tips

< Back to all articles

Farmers have enough to worry about at the start of every spring. Late-fall harvest because of wet conditions allowed for seedling disease pathogens to develop and live in the soil. Throw in a cool, wet spring, and the chances of soybean seedling disease risk and seed decay increase tenfold. In these conditions, farmers will see lower seed quality and reduced seed vigor, germination and emergence.

The best way to protect against these challenges is having soybean seeds treated with a fungicide to increase the chances of germination and prevent seedling diseases. Make sure the fungicide seed treatment package is recommended for control of Phomopsis. With the appropriate seed treatments, germination can increase by 10% to 15%. Consult your ag retailer and agronomist to make the right seed treatments decisions and monitor emergence closely.

In addition, use these tips to protect your soybean yield as we progress through the season.

  1. Invest in high-quality genetics and seed treatments. The best protection from these diseases starts in the bag. Along with great genetics, include a seed treatment application with several active ingredients to fight disease and protect against Phomopsis seed decay.
  2. Identify soybean seed disease. Scout fields early for signs of damaged seedlings or low-quality plants. The Diaporthe and Phomopsis disease complex can impact all parts of soybean plants. Infected seedlings are elongated, shriveled, severely cracked and flattened and may be covered by a white mold. Stems and pods will display linear rows of black specks.
  3. Apply foliar fungicides. The fungi survive on infected soybeans plant material and seeds and can overwinter. Use a fungicide treatment near R5 to protect seed quality, improve plant establishment and help increase germination rates by 10% to 15%. Talk with your agronomist to select the right package to control Phomopsis.
  4. Rotate crops annually. Alternating crops and tillage will reduce the prevalence of Diaporthe and Phomopsis species by removing nonhost crops, including corn. Keep field management in mind to minimize soil erosion and maintain soil quality.
