This invention relates to certain natural diatomaceous earth granule compositions which can be broadcast, i.e., dry spread on the soil to deliver a pesticide or fertilizer. The granules retain their physical integrity when spread, and have the unique property to spontaneously disintegrate when irrigation water is applied or rainfall hits the particle. Upon wetting, the particle disintegrates (blooms) to cover the soil surface. This bloom can cover an area many times the original area covered by the granule. The granules have high loadings of the diatomaceous earth, i.e. from about 35 to about 95 weight percent and contain from about 5 to about 40 weight percent of a surfactant system which exhibits excellent disintegration; rewetting and binding properties. Bioactive compounds can be loaded at up to 60 weight percent of the granule. Bioactive compounds may be formulated products or technical grades and may be homogeneously distributed throughout the granule or spray impregnated onto the granule.

Broadcast carriers for pesticides and their use

A low volatile organic compound co-solvent system is disclosed for preparing emulsion concentrates of low melting organophosphorous insecticides wherein the bioefficacy of the insecticide active is significantly enhanced. The co-solvent system comprises a water-soluble ethoxylated fatty acid/rosin acid-nonionic surfactant composition.

Concentrates of organophosphorous insecticides

A low volatile organic compound co-solvent system is disclosed for preparing emulsion concentrates of water-insoluble pesticides having a melting point of less than about 110.degree. C. The co-solvent system comprises a water-soluble ethoxylated fatty acid/rosin acid-nonionic surfactant composition.
