Several calls have come in about wilting, watering and daytime cooling. In most instances, it is too early to be doing mid-day cooling. That is really only needed when fruit are present. Otherwise, assuming you have been keeping up with the water needs of your plants, they should be able to cool themselves without needing additional irrigation during the day. If you have not been adequately watering, you may need to provide extra water during stressful times, but the best thing is to keep the plants well-watered prior to stressful temperature events.
Out-of-blooms counts have been variable, but many growers have put on their first fruitworm sprays; the Howes will be coming along later. The bloom does seem to be delayed in some cases, so do several out-of-bloom counts so you can have better confidence when you hit 50%.
Some folks may be monitoring weevil and brown spanworm populations during bloom, especially when they have been problematic in the past. Once fruit set has occurred, grass herbicides containing clethodim (Select, Intensity) can be applied to the vines.
