Representatives from Syngenta Crop Protection and Bayer CropScience recently advised no-till soybean growers to shift their focus from insect control to disease management this year, as diseases present a greater opportunity to boost yields and profits. Experts highlighted the importance of proper fungicide timing and application to combat common soybean diseases.

Why it matters

No-till farming practices can increase the risk of certain soybean diseases, so growers need to be proactive in their management approach. By prioritizing disease control over insects, growers may be able to achieve higher yields and better returns on their no-till soybean crops.

The details

Bayer's senior technical service representative Mike Weber advised no-till soybean growers to focus more on disease management than insect control, stating 'This is where higher profits will be earned.' Syngenta tech rep Leon Hunter said the most effective fungicide timing is when soybeans reach 1/4- to 3/4-inch pods on the fourth node and above. He recommended using Quadris, a broad-spectrum fungicide with a novel mode of action, at a rate of 6.2 ounces per acre in at least 10 gallons of water. Many growers are also tank-mixing the fungicide with Warrior insecticide to control both diseases and insects during the critical reproductive stage.

  • The recent National No-Tillage Conference featured pest control advice for no-till soybean growers.

What they’re saying

“This is where higher profits will be earned.”

— Mike Weber, Bayer's senior technical service representative

“For disease control in no-tilled soybeans, timing is critical to gain a yield advantage. Research indicates fungicides applied on 1/4- to 3/4-inch pods on the fourth node and above provide the most effective timing.”

— Leon Hunter, Syngenta tech rep

What’s next

Growers should consult with their local agronomists and chemical suppliers to develop a comprehensive disease management plan for their no-till soybean fields.

The takeaway

By shifting their focus from insect control to proactive disease management, no-till soybean growers may be able to unlock higher yields and profits from their crops. Proper fungicide timing and application will be critical to combat the increased disease pressure that can come with no-till practices.
