|Getting ready to spray the pecan breeding block|
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.

We plan to spray our grove over the next few days adding an insecticide for casebearer control and a fungicide for scab control. The weather forecast for this weekend is hot and dry. To get the best spray coverage of the pecan foliage, I'll start spraying at daybreak and quit when temperatures top 80 degrees (F).

I cut open a couple of galls with the hopes of photographing phylloxerans inside (photos above). However, what I found in each case was a syrphid fly larvae working to devour all the phylloxerans inside the gall. In photo "A", the syrphid fly larva had cleaned out the gall completely. In photo "B", there were just a few phylloxerans left. Syrphid flies are probably the reason why pecan leaf phylloxera is only a minor pest of pecans.
