European Commission Approves Agrisure DuracadeFarmers with corn rootworm pressure will have new options to combat the pest in 2020. The European Commission approved Syngenta’s Agrisure Duracade for import. Duracade will be sold as stacked traits, including Agrisure Duracade 5222 E-Z refuge and Agrisure Duracade 5122 E-Z refuge. All individual components of the stacks are now approved. This most recent approval covered corn grain and derived products for food and feed use in European Union countries. The company claims the 2020 Duracade launch class has an advantage of 4.1 bu. per acre over non-Duracade products. USDA approved Duracade for planting in 2013.

Tar Spot Could Cause Losses Up to 38 Bu. Per AcreFor the 2019 season, farmers in Iowa, Illinois, Indiana, Ohio, Michigan, Wisconsin and Florida - and adjacent states - are encouraged to scout for tar spot. The disease‘s severity has increased every year since its discovery in 2015. Fields with 40% to 50% tar spot severity on the ear leaf by R5 or R6 saw a loss of 16.8 bu. to 38.7 bu. per acre in 2018, according to a recent study from University of Illinois, Michigan State University, Purdue University and University of Wisconsin. The research effort examined hybrids at the R6 (physiological maturity) growth stage by estimating the amount of tar spot, which ranged from 15% to 50% of the leaf area affected. Here’s a summary of their findings:
- For every 1% increase in tar spot severity on the ear leaf, there was a 0.48 bu. per acre yield loss for hybrids with 92- to 106-day relative maturity.
- For every 1% increase in tar spot severity on the ear leaf, there was a 0.83 bu. per acre yield loss for hybrids with 107- to 114-day relative maturity.
West Central Unveils Trivar Broadcast Fertilizer AdditiveIn an effort to make phosphorus and micronutrients more available to the plant, West Central is introducing Trivar fertilizer additive with three modes of action. The additive is designed to be impregnated on dry fertilizer for fall or spring applications. Its benefits include:
- Protecting the key micronutrients in the soil from binding with phosphorus.
- Using a nutrient-focused enzyme to convert organic phosphorus to plant available inorganic phosphorus.
- Adding zinc and boron to every single one of the product’s granules.
BASF’s Revysol Fungicide Gains EPA RegistrationBASF recently received registration for its Revysol fungicide from EPA. This is the first isopropanol-azole active ingredient of its kind to hit the market. Revysol targets a broad range of diseases in several crops. Its unique isopropanol link can also control DMI-resistant fungal strains. In recent BASF trials it showed efficacy against Northern corn leaf blight, cercospora leaf spot in sugar beets, frogeye leaf spot in soybeans and powdery mildew in grapes. The company lists the following benefits of the new product:
- Can be used on a variety of crops.
- Faster plant uptake for immediate protection.
- Rainfast and has low water solubility so the active ingredient has longer residual activity.
- Certain features provide curative activity.
