The invention describes synergies derived from combinations of bicarbonates, sorbic acids, and carrageenans as formulating agents in pesticides. Bicarbonates are widely used as pesticides in agriculture, though often ineffective unless used in combination with horticultural oils. Horticultural oils are incompatible with sulfur, another common pesticide, which often limits the use of horticultural oils and thus effective applications of bicarbonates. The present invention finds synergies with combinations of carrageenans, sorbic acids, and bicarbonates without an incompatibility with sulfur.
