The pecan industry has seen an influx of new growers over the past 5-10 years, many of whom are still quite new to understanding the chemistries and products available to growers to fight disease and keep their trees healthy.
The end goal of course is to produce the best quality pecans with the largest crop load your trees can withstand. Caring for your tree’s health is of vital importance in order to achieve these goals. Regular soil and leaf sampling can give detailed insights into the trees health, but disease management tends to be more visual in nature.
Scab is our main concern for much of the growing season in the southeastern US, and Mr. Veal has shared with us how one of their products can help growers manage scab at various times throughout the growing season.
Mr. Veal works with growers in the southeastern pecan growing region to help manage scab in trees. One of their products has caught on in a big way and is now being utilized by growers all across the southeast and into Texas to manage scab pressure and improve tree health.
With growers asking when the best time and rates for applications, Mr. Veal shared a quick update with us for growers to utilize in order to better understand best application timing and rates for KPhite 7LP. Mr. Veal has broken up the use in pecan trees based on scab susceptibility. If you have more questions growers are encouraged to contact Mr. Veal about rates and application timing.
