Abstract: 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.

Abstract: A solid, water-soluble complex comprising:a) a polysiloxane of the formula: ##STR1## wherein n is from 2 to 6; a is from 8 to 25; and b is from 0 to 25; and the oxyalkylene groups may be random or block mixtures; y is from 0 to 5; x is from 1 to 5; and R is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, and a C.sub.1 -C.sub.4 alkyl ester; or ##STR2## wherein A is a linear or branched alkyl having 6 to 30 carbon atoms; G is a glycol moiety of the formula --R'(OCH.sub.2 CH.sub.2).sub.m OR" wherein R' is a divalent alkylene group having 2 to 6 carbon atoms; R" is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, and a C.sub.1 -C.sub.4 alkyl ester; m is 8 to 100; y is 0 to 5; X is 0.1 to 2.5; and z is 0.1 to 5.0;b) a complex-forming agent of the formula: ##STR3## wherein X is O, S, Se, or Te, and c) a readily clathratable polyoxyethylene, e.g. a tridecyl alcohol ethoxylate having eight or more oxyethylene units.

Abstract: Stable, concentrated non-aqueous suspensions of water-soluble solids are prepared by using a water soluble active compound comprising water hydratable polysaccharides, biocides, fertilizers and mixtures thereof dispersed in water-miscible organic liquid carriers, preferably lower alkadiols in conjunction with a specific three component surfactant system, i.e., a system comprising a nonionic polymeric viscosity modifier surfactant; an anionic surfactant; and a nonionic surfactant having a bulky hydrophobic substituent group.
