California Red Scale Degree Days are Off to a Fast Start!
We usually hang traps for California red scale (CRS) the first of March at Lindcove REC and see the first flight start up a couple of weeks later. Not this year! The temperatures have been high and everything, including bloom is early. The CRS biofix for Kern was in late February and for Tulare foothills the first week of March. Unless we have an extreme downturn in temperatures, the first generation of crawlers will likely be early *in late April for Tulare). You can follow the general county accumulations of degree days weekly on our web site to get an idea of how fast things are progressing - California red scale degree days.
Bloom is early and degree days are accumulating fast for pests such as California red scale
