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.
