We are 2nd and 3rd week into squaring now, and we’re starting to put out our plant growth regulators. I had an unexpected 1 inch rain at the house yesterday afternoon.With all the rain we are having, we need to keep in mind the ‘rainfast’ of our PGRs. Below has written out each of our mepiquat and mixed products. Generally, when a surfactant is used, we can cut the rainfast in half. Pentia is more expensive, but with a 2 hour rainfast (1 hr with surfactant), we may find it beneficial our current conditions.
