Agricultural compositions that employ structured surfactant systems to suspend water-insoluble or sparingly soluble agricultural actives and/or adjuvants are disclosed. Also disclosed are agricultural compositions that combine structured surfactant systems with electrolytes to form structured electrolyte compositions. The structured surfactant systems, both with and without electrolyte, suspend one or more agricultural actives and/or crop oil and non-aqueous adjuvants to provide agricultural compositions that can combine combinations of actives in a single, stable composition.

The present document describes a method of producing sulfur particles by injecting an unbroken stream of molten sulfur under a pulsation free pressure, from a distance, into tempered water moving at a velocity, to produce a physical reaction of said molten sulfur with said tempered water to produce sulfur particles. Also described are sulfur particles produced by the process and methods of using the same for fertilizing soil.

A controlled-release fertilizer composition includes coated fertilizer particles having granules substantially encapsulated with a polyurethane coating layer formed from a polyol composition and an isocyanate curing agent. The polyurethane coating layers include inorganic particles. Methods of making and using the controlled-release fertilizer compositions are also disclosed.

Compositions and methods are provided for enhancing soil health and/or plant health. In particular, the subject invention relates to compositions comprising microbes and/or their growth by-products for use in improving fertility, salinity, water retention, and other soil characteristics, as well as controlling pests and stimulating the growth of plants. In certain embodiments, the growth by-products are biosurfactants.

A composition is provided comprising as component (A) at least one insecticide; and as component (B) at least one fertilizer. The composition is effective in controlling nematodes and in promoting plant growth. The at least one insecticide is preferably selected from thiodicarb, abamectin, imidacloprid, fipronil and mixtures thereof. The fertilizer component preferably comprises one or more amino acids and one or more micronutrients. A method of controlling nematodes and/or promoting plant growth using a combination of component (A) and component (B) is also provided.

A biostimulant concentrate includes purified water and a solubilizer, triacontanol, an array of brassinosteroids selected from the group consisting of brassinolide, brassinone, dilholide, homobrassinolide, and combinations thereof. The ratio of tricontanol to the array of brassinosteroids is between 3.33:1 on a w:w basis to 50:1 on a w:w basis in one embodiment of the invention. Preferably, the array of brassinosteroids concentration is between 40-70 ppm in the biostimulant concentrate and the triacontanol concentration is approximately 3000 mg/l. The brassinosteroid includes brassinolide having the chemical formula C.sub.64H.sub.124O.sub.26. The dilholide has the chemical formula C.sub.28H.sub.46O.sub.6. The brassinone has the chemical formula C.sub.27H.sub.46O.sub.5. Preferably, the at least one brassinosteroid is selected from the group consisting essentially of brassinone, dilholide, and homobrassinolide.
