Three New Herbicides to Control Weeds

Farmers need more tools in their toolbox to gain control of resistant weeds. BASF is offering Zidua SC, a suspension concentrate liquid formulation herbicide, Arysta LifeScience is offering Everest 3.0 with safener technology and Summitt Agro USA is launching Shieldex 400SC HPPD inhibitor technology.

Zidua SC is a group 15 herbicide that targets waterhemp and Palmer amaranth. BASF says Zidua SC is the lowest use rate of any group 15 herbicide available. The product also offers a wide application window from fall to early preplant to early postemerge in corn and soybeans. Zidua SC is labeled for use in corn, cotton, peanuts, soybeans, sunflowers and wheat. Visit for more.

Everest 3.0 is a group 2 herbicide with “new carrier technology” to provide broad-spectrum broadleaf and grass control.
Arysta LifeSciences’ new wheat herbicide formulation is highly concentrated to allow for lower use rates and boasts a longer shelf life. Arysta says it controls yellow foxtail, wild oat, green foxtail, bromes, barnyard grass and rattail fescue.

Application for spring, winter and durum wheat is one leaf up to 60 days before harvest. Learn more at

Summit Agro USA is launching Shieldex 400SC, a new corn herbicide for the 2018 growing season. It features HPPD inhibitor (group 27) technology for broadleaf and some grass control.

Shieldex 400SC provides control against especially troublesome weeds such as Palmer amaranth, waterhemp, giant ragweed and giant foxtail. You can apply the product on corn up to V6 growth stage. The herbicide is sold through Helena Chemical Company and Tenkoz Inc. For more, visit

NemaStrike Pulled for Skin Irritation

After finding cases of skin irritation, Monsanto is pulling NemaStrike seed treatment for 2018 for farther review. Monsanto recently received Environmental Protection Agency approval for the nematicide.

So far, the cases reviewed indicate use of personal protective equipment is a key factor in the safe use of the product. Monsanto says it is “out of an abundance of caution” it is stopping commercialization while it reviews the situation. However, “Ground Breaker” trials will continue this spring.

“We did not make this decision lightly,” says Brian Naber, U.S. commercial operations lead at Monsanto.“We will provide additional information to you, including which alternative Acceleron Seed Applied Solutions products will be available.” Learn more at

New Seed Treatment Portfolio

Ridgeline portfolio, by West Central Distribution, offers seed treatments with multiple fungicide and insecticide chemistries for soybeans and cereal crops.

The lineup features Halifax fungicide, Halifax fungicide and insecticide, Lancaster fungicide, and Lancaster fungicide and insecticide. Halifax fungicide uses two types of fungicide seed treatments for soybeans and other legumes to control phytophthora. Halifax fungicide and insecticide has three fungicides and one insecticide. Lancaster fungicide has three fungicides to be used on cereal crops. Lancaster fungicide and insecticide adds “next generation” insecticide and systemic fungicide.

The products will be available in a variety of sizes such as 2x2.5-gal. jugs, 15-gal. kegs and 250-gal. shuttles. For more information, visit

Pesticides Rare in U.S. Foods

Each year the Food and Drug Administration (FDA) tests food for pesticides that exceed allowable limits set by the Environmental Protection Agency (EPA). FDA is required to enforce these standards in domestic and imported foods in the U.S.

In fiscal year 2015, food tested was generally in compliance with EPA standards—with domestic food performing higher than imported.

FDA analyzed just under 6,000 samples—5,572 human foods and 417 animal foods. The agency tested more import samples (4,737) since they usually have more residue than domestic samples (835).

Tested food came from 111 countries and 39 states, the District of Columbia and U.S. territories. More than 98% of domestic food and 90% of imported foods were compliant. Furthermore, no pesticide residue was present in 49.8% of domestic food and 56.8% of imported human food samples. Therefore, less than 2% of domestic and 10% of imported human foods violated federal standards.

New Micronutrient Formulations

Verdesian Life Sciences introduces three MicroSync specialty granular micronutrient products. The free-flowing, low-dust and uniform formulations are designed to be blended with NPK granular fertilizer for broad care crops. MicroSync is available in these formulations:

  • MicroSync Plus contains sulfur, calcium, zinc and boron in a unique formulation to synergize the availability of secondary and micronutrients for plant uptake.
  • MicroSync Pro contains manganese, in addition to sulfur, calcium, zinc and boron for crops that require supplemental manganese.
  • MicroSync Ultra contains sulfur, calcium, zinc, manganese and boron, and also adds humic acid, which helps to chelate/bind cations.

The products are built to supply on-demand sulfur availability to prevent or correct micronutrient or sulfur deficiencies. Rates range from 10 lb. to 40 lb. per acre. The standard rate is 20 lb. per acre. For more information, visit
