Second scab spray

Getting ready to spray the pecan breeding block
    Over the weekend we had several light rain showers followed by brutal heat wave. With ample heat and humidity, pecan scab can spread rapidly so I decided to make my second pecan scab spray of the season. This time I used Quadris Top fungicide for scab and added an insecticide (Bifenthrin) to control shuckworm and Japanese beetle.
    When spraying at this time of year, I like to get started before dawn and quit before 11:00 am. Airblast sprayers work best when the air has high relative humidity and the spray material fogs up into the canopy of the tree.
