SETRE® FA-1 (Formerly HM9224) Fertilizer Amendment to Prevent Spray Mix Incompatibilities of Insecticides and Foliar Fertilizers

M. Powell, J. Roberts, B. Mack, and A. Underwood


 
ABSTRACT

Due to economic and convenience reasons, the preparation of multi component spray mixes has become a standard procedure for most agricultural pesticide applications. In many cases, these spray mixes contain fertilizer and/or micronutrients as one or more of the components. This oftentimes results in spray mix incompatibility problems which can have a negative effect on pesticide efficacy. These incompatibilities are due to both chemical and physical factors.

Chemical based incompatibilities are the most serious consequence of spray mix incompatibility. They occur when one or more of the components chemically react with one another. The result of this reaction can be neutralization of the pesticide active ingredient(s). These problems are not common, however, and are usually preventable. The most common form of spray mix incompatibility are problems that arise from physical changes in the spray mix. These changes include viscosity, dispersion, and uniformity. In the past these problems have been difficult to anticipate and/or control. The subject of this presentation is a new surfactant based fertilizer amendment (FA-1) from Helena which has the potential to resolve many of these problems.

Unlike past attempts to use surfactants to correct spray mix incompatibilities, the Setre(®) FA-1 program utilizes a preventative approach allowing insecticides to mix with liquid urea and/or potassium nitrate fertilizer. Both research and field experience has proven this approach to be successful in overcoming insecticide/fertilizer spray mix incompatibility.
