‘Timing is Key’ When it Comes to Tar Spot

by | Feb 7, 2022 | Indiana Agriculture News, News Feed

Northeast Indiana Pioneer agronomist Lance Shepherd speaks to a customer at the 2022 Fort Wayne Farm Show.

2021 treated many farmers very well, and Pioneer agronomists are very pleased with how Pioneer hybrids and varieties performed.

“It was a stellar year in 2021, although throughout the growing season we didn’t know if it would be with lots of rain, wet feet and so forth,” says agronomist Lance Shepherd, who covers northeast Indiana for Pioneer.

“We saw phenomenal yields in both corn and beans throughout the season. We had some very new and exciting products such as 953 and 1136 that are just rising to the top of the ranks. Same on the side of soybeans with Plenish® really taking off with new premiums, kind of regenerating excitement around soybeans as well with Plenish® bringing in some really nice premiums in northeast Indiana.”

HAT caught up with Shepherd at the recent Fort Wayne Farm Show where most of the discussions revolved around input costs for 2022, but there was also some conversation about tar spot and how to combat it. Shepherd says timing is key.

“So, first and foremost, if I am under a pivot or irrigation, I am looking at a two-pass application regardless because I’m always going to have that conducive environment. If I’m not willing to make a two-pass application, I’m going to look at pushing my application timing back to R2, around that blister timeframe, so that I can control tar spot and northern and kind of give up some of that front end whereas we’re normally applying around VT or pollination complete.”

Shepherd adds that Pioneer has a lot of hybrids that have great staygreen, and he’s seeing a correlation with that to tar spot tolerance.
