My sunflowers started dying off and turning brown around the end of August. The last picture was taken the first week of September. They were planted April 28th, and maturity was supposed to be 110 days.

I sprayed Treflan at 1.5 pts per acre preplant. In previous years, the planted field was overgrown with pigweed.

The planter is a Dearborn. The company was bought out by Ford in the early 50's, so my planter was made before then. Depth setting is by the top link of the 3pt hitch.

Here's a link to the sprayer. Each nozzle has a mesh filter, bigger than a 22 casing but smaller than a 38 spcl casing.
