Time to Turn on the Water!

Some early pecan varieties have reached shell hardening and others are rapidly approaching. This means that the water use requirements of pecan are about at peak demand and will remain so through kernel filling. Therefore growers should have their irrigation systems running at full capacity at least by next week…

Using soil and leaf…

It is free to the grower and provides orchard-specific information about the potential risk for scab resistance to the most commonly…

Bot Canker

I’ve seen a number of young orchards recently with trees suffering from die-back. While much of this has been related to cold damage, some trees are feeling the effects of a subtle problem that often goes unnoticed until it becomes severe. Botryosphaeria canker or “Bot canker” is caused by a fungus…
