As we approach the start of August, I am beginning to see evidence of cut-out in cotton fields around the Valley. The timing couldn’t be better.
|There is a large upswing lygus nymphs in these fields.|
Retention is still good, but these numbers should give
some pause, especially the number of immobile nymphs.
|Fruiting branches from all fields. Have we reached cut-out?|
If you are battling with rust disease, knock the leaves off tree to reduce overburdening inoculation. In late October, apply 25 to 35 pounds of zinc sulfate to trees to knock off leaves. When applied in the fall, this nutrient can help break the rust and shot hole disease cycle. It’s important to remember when you knock the leaves off with that zinc spray you’re not going to get any uptake of any that zinc. So if you have a zinc deficit, you need to make that application earlier in the post-harvest period, probably with the boron.
