Went to get Cadre, and Impose was all the local feed store had in stock. He said it's pretty much the same as Cadre, but when I read the label, there was no info at all on sunflowers. Couple of questions:

1. Do I go with the same rate as Cadre? 4oz to the acre?

2. What kind of surfactant and how much per acre?

3. When to spray? I've read at 21 days after planting, and also read the 4 to 6 leaf stage. Does that mean the vegetative 4 to 6 or the R4 to R6 stage? We planted on Mother's Day so 21 days would be this Sunday and the attached picture is what they look like now.
