Two Huma® products, Promax® and Zap®, had previously been shown to be successful in managing soil-borne diseases in strawberries. Objectives The primary objectives of this study were to assess the efficacy of Promax® and Zap® in reducing...

Objective  The purpose of this research project was to evaluate how a special blend of fertilizer solution and a root dip made of Huma® products with Micro Carbon Technology® affect strawberry yield when compared with a control program of grower’s standard fertilizer and a competitor root dip product.  Materials & Methods  Strawberry cultivar San Andreas...

Objective  This field trial assessed the effects on strawberry yields of replacing field fumigation with periodic applications of Huma® Promax® and Zap® and replacing a grower’s standard fertilizer program with irrigation-applied Ultra-Precision™ blended liquid Huma® crop nutrition products.  Materials & Methods  This trial was conducted in Arroyo Grande, Calif., using Portola strawberries planted in 40’...

Objective  This field trial assessed the effects of Promax® and Zap® on top of fumigation—plus additional foliar applications of 4 Huma® fertilizer products—on the yield of Portola strawberries when compared with the grower’s standard crop nutrition program.  Materials & Methods  This trial was set up in a complete randomized-block design conducted during the growing season...

Objective  This two-year trial aimed to assess the suppression effects of Promax® and 2 types of beneficial nematode treatments (S. feltiae and S. riobrave) versus a control on plant-parasitic nematodes (Stunt, Lance, Ring, and Spiral) for English Boxwood (Buxus sempervirens L. var. suffruticosa) ornamental plants.  Materials & Methods  Each experimental unit consisted of 2 English...

Introduction  A field trial to test efficacy of Huma® Promax® as a cropprotection product for strawberries (Fragaria sp.) was applied in a location known to have spring disease problems with either Fusarium or Macrophomina pathogenic fungi.   This report is based on a field trial with strawberries conducted by Holden Agricultural Research and Consulting submitted on...
