It is time again for the Rice Diseases Survey. The objective of the Survey is to document the incidence of rice diseases in Sacramento Valley rice fields so that the Air Resources Board agrees to continue to allow the rice industry to burn up to 25% of the acreage.
I just wanted to do a quick update on blast. I have not seen any other blast besides the one I reported on an earlier post. PCAs that I have spoken to have not seen blast either. With the cooler temperatures, conditions for blast are not as good.
Yesterday, I visited a farm with blast in Glenn County. In this case, the grower seeded M-210, and as an experiment, he planted some M-105 in a very small area at the time of clean up herbicide application. This is a location where blast is common.
