As the nuts fill out they become heavier.  The limbs bend over and fill the space between the rows.  Tractor work becomes difficult and hazardous.  This is no time for inexperienced drivers.  Here we are applying a spray which includes a fungicide (target: rust, scab, and alternaria), insecticide (target: Peach Twig Borer and Navel Orangeworm), and a miticide (target: mites). My hope is that this will be the last spray necessary for this season.  Besides the risk and discomfort to drivers, traveling through the orchard after the beginning of hull split (late June) knocks a lot of nuts off the trees.
