Fungicides

Unlike the early tar spot problem farmers experienced in 2021, the disease wasn’t first reported in Indiana until August this year. Darcy Telenko studies the timing of fungicide applications in battling tar spot.

“If we cut 20 seconds on every fill, and we do 50 fill ups in a day— we save 25 minutes,” Cody Ray says. “That could be another 10 acres a day.”

Corn subjected to heavy rainfall can still deliver a significant yield response to a nitrogen application -- in some cases, up to 60 bu.

Breeding advances brought an era of advanced disease control. The future of disease tolerance will use advanced breeding with targeted approaches that help maximize corn and soybean yield potential.

With tar spot’s ability to rapidly spread, agronomists fear another wave of the disease will hit the Midwest again this season.

Tar spot and southern rust are increasing concerns and require a proactive management plan. Some fungicides can mitigate these and other diseases while protecting plants from stress. Retailers can guide your decisions.

Availability could be a challenge this season. If you can only make one application, pull the trigger between tassel and R3 in corn and between R2 and R3 in soybeans, advises Ken Ferrie, Farm Journal Field Agronomist.

Alec Horton begins every wheat crop aiming for 100 bu. per acre dryland yield through seed treatments, proper seeding rates, tiller promotion, vegetative growth reduction and moisture conservation. However, he didn’t see a 121.48-bushel bin buster in the cards when he planted “Joe” in the fall of 2015.

Rotation is only defense against this new soybean disease
