ABSTRACT:
Compatibility agents were developed for improving the compatibility and stability of mixtures of liquid fertilizers and liquid or wettable powdered pesticides. These compatibility agents contain water, a low alkanol and an alkylaryl polyoxyethylene glycol phosphate ester. The compatibility agent is used at a preferred concentration range of 0.1 to 0.4% of the fertilizer solution. The preferred compatibility agent not only improves the compatibility of liquid fertilizer-pesticide mixtures, but also results in uniform and stable mixtures ensuring accurate pesticide applications. The preferred compatibility agent is a mixture containing about 16% water, about 20% methanol and about 64% of an octylphenol polyoxyethylene glycol phosphate ester.
