Disclosed is a pesticide having a polysulphane as active agent, and being either synthetically prepared or derived from garlic oil. The active is held as a disperse oil phase within an aqueous continuous phase. A surfactant, typically comprising a carbohydrate fatty acid ester is employed to retain the two-phase system. The diameter of the emulsion droplets, and/or the surface area of the emulsion system, is controlled to optimise the effectiveness of the pesticide contained therein. Also disclosed is a granule having an inert carrier matrix such as a diatomaceous earth or a cellulosic material, for example wood cellulose, in which the poly sulphane-containing emulsion is supported. The use of emulsion containing granules in soils to release pesticide in a controlled manner into soil is also disclosed. Also disclosed is the use of the emulsion system for accelerating breaking of bud dormancy.
A biopesticide emulsion system having a first continuous phase comprising water and a second discontinuous phase comprising a biopesticide derived from a concentrated liquid garlic juice, a synthetic polysulphane or mixture thereof, and including an emulsifying agent to retain the two phase system.
An emulsion system according to any preceding claim, wherein the emulsion as a specific surface area of more than 200,000 cm2/mL.
An emulsion system according to any preceding claim, wherein the emulsifying agent is an esterified carbohydrate.
An emulsion system according to any preceding claim, wherein the emulsifying agent is present at less than 3% w/w of the emulsion system, or less than 2% w/w.
An emulsion system according to any preceding claim, wherein the emulsifying agent is present at greater than 0.25% w/w.
An emulsion system according to any preceding claim, wherein the percent w/w ratio of continuous to discontinuous phase is greater than 20:1, optionally, wherein the ratio is greater than 30:1.
An emulsion system according to any preceding claims, for accelerating breaking of bud dormancy.
A granular pesticide comprising a granular matrix, said granular matrix retaining a biopesticide emulsion having a first continuous phase comprising water and a second discontinuous phase comprising a biopesticide derived from a concentrated liquid garlic juice, a synthetic polysulphane or mixture thereof, and including an emulsifying agent to retain the two phase system.
A method of manufacture of a granular biopesticide comprising the steps of:
The use of a granular biopesticide composition, wherein the granular biopesticide composition includes a granular matrix and an emulsified biopesticide absorbed within said matrix wherein the biopesticide is derived from a concentrated liquid garlic juice, a synthetic polysulphane or mixture thereof.
