Kphite 7LP Use Growing in Pecans

Pecan growers are increasingly incorporating Kphite 7LP into their pecan disease management programs, Gary Veal, Technical Sales Agronomist for Plant Food Systems, Inc. says “growers are telling us that they are keeping Kphite 7LP in the disease programs through the growing season.”

 

According to Veal,some growers are tank-mixing the 2 quart per acre rate with other nut-scab fungicides like Miravis Top and Elast. Still others are keeping Kphite 7LP in their rotation at the rate of 2 or 3 quarts per acre.

 

Kphite 7LP is our most systemic pecan fungicide available, says Veal. It has been long established that Kphite 7LP works in two key ways. First, it has a direct impact on pecan diseases like pecan scab, glomerella (aka anthracnose), powdery mildew and others. The second way that Kphite 7LP works in plants is to improve overall tree health. A healthier tree withstands stresses including diseases, says Veal.

 

 

Veal says there is strong argument for making Kphite 7LP the final fungicide application in August. Growers can choose between the rates of 2 or 3 quarts per acre as stand-alone spray. If scab is low to moderate, a grower can apply the 2 quart per acre rate. If scab is moderate to severe, a grower can apply a 3 quarts rate per acre. 

 

“The benefits of using Kphite 7LP in the final pecan disease spray are apparent in orchards across the southeast”, says Veal. “Holding disease down as we enter the nut-fill stage is important to production and quality results. Maintaining leaf health is important for the current crop load as well as next season’s crop.”

 

Controlling diseases and maintaining leaf health through November is important to maintaining adequate carbohydrate storage through the dormant season. There is no better leaf health fungicide on the market, says Veal. There is some evidence to suggest that the higher use rates of Kphite 7LP can carry over to next year’s leaf flush. That is one topic that we want to further investigate, says Veal.
