摘要:
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.

摘要:
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.
摘要:
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.
摘要:
Solid surfactant-impregnated, water-soluble fertilizer compositions are disclosed together with aqueous concentrates made therefrom. The use of dilute aqueous compositions made from said concentrates to enhance the rewetting of water uniformity and nutrient retention characteristics of initially untreated plant culture media is also disclosed. The fertilizer composition solids are friable and are composed of from 65 to 99 weight percent water-soluble fertilizer; and from 1 to 35 weight percent of a surfactant system comprising water-soluble nonionic surfactant and alkyl polyglycoside in a weight ratio of from less than 2:1 to 1:5. When these solid compositions are dissolved in water to form concentrates having from 20 to 50 weight percent fertilizer, the concentrates are both single phased and extremely stable.

The use of dilute aqueous water-soluble fertilizer compositions are disclosed to enhance the rewetting of water, uniformity and nutrient retention characteristics of initially untreated plant culture media and soil. The aqueous fertilizer compositions contain water-soluble fertilizer; and a surfactant system comprising water-soluble nonionic surfactant and alkyl polyglycoside in a weight ratio of from 2:1 to 1:1
摘要:
Systemic mitigation of the heat stress damage to plants and pre-harvest fruit caused by environmental stress on the plant and fruit is realized by applying to the root zone of the plant a bioefficaciously effective amount of a composition selected from the group consisting of ethylene oxide-propylene oxide block copolymer, alkyl ethers of ethylene oxide-propylene oxide block copolymer, alkyl polyglycoside, and combinations thereof.
摘要:
Water repellent soil is treated with low concentrations of EO/PO block copolymer having an HLB value of less than or equal to 2; an average molecular weight of greater than 3,000; and a percent hydrophile of 10 in order to rapidly increase the wetting rate of the water repellent soil.
