Testing Results Overview

  • Highly effective herbicidal activity on small broadleaf weeds and good control of smaller grasses for species tested to date.
  • Effective burndown of larger broadleaf and grass species tested to date.

BF1002 has been evaluated in both greenhouse trials for efficacy on specific weeds and overall weed control of various field trials. In general, BF1002 provides excellent control of broadleaf weed seedlings. Grass weed seedlings may have some regrowth and require higher initial rates or retreatment. Larger, more mature weeds may require higher rates, application volumes or retreatment. There appears to be essentially no soil residual herbicidal activity with BF1002 when used as directed. 

The following research trial photographs depict Belvedere Foliar formulations in several settings. The results of several third-party verification trials are presented under the tabs on the TESTING page. All additional BelFol field and greenhouse trial data are available for review and discussion to interested parties under the terms of an appropriate Confidentiality Agreement. 

Figure 1: Napa Valley cabernet sauvignon vineyard 30 days after application of an early formula of BF1002 RTU sprayed-to-cover. Strip to left side of this row is untreated, as were weeds in distance and to left and right of the test row. This was one of many early field and greenhouse trials to verify the “nutrient toxicity” concept to support patent applications.
