Our field continues its blooming. The heads in the foreground
are nearly finished blooming, while heads further back and on the sides are
at about the R5.7 to R5.8 stages. We had a small rain shower
yesterday. It rained 0.48 inches. Not bad, but we could use some
We've been seeing heads for about six days now, so these next few photographs can be considered a review. Would you agree these two heads have completed about 80 to 90 percent of their flowering? If so, then they are in the R5.8 to R5.9 stages.
These two heads are in the R5.9 to early R6 stage. On the right, the R6 plant's ray flowers haven't started wilting yet, but the center is completing flowering today. So, technically we may be off a day or so by calling it an R6 plant.
Well, I knew it couldn't last forever. This little moth is one of the most notorious insects in a sunflower field. This is the sunflower head moth and it is quite destructive. It lays eggs in the head, the eggs hatch and the larvae burrow in the head causing all sorts of damage. I don't think we have too many moths flying in our field, but we need to be sure. We'll set some traps tomorrow.
