  • Patent number: 10085442
    Abstract: The present invention relates to a composition comprising an aqueous continuous phase; a first dispersed phase which comprises styrene-maleimide copolymer particles; and a second dispersed phase which is either oil droplets, suspended particles or a capsule suspension; and to use of those compositions to control agricultural pests or diseases. It also relates to use of such compositions where rainfastness is important.
    Type: Grant

  • Patent number: 9458085
    Abstract: This invention relates to a formulation comprising a compound of formula (I) where R1 and R2 are each independently hydrogen, optionally substituted C1-18 alkyl, optionally substituted C1-18 alkenyl, optionally substituted C3-8 cycloalkyl, optionally substituted C3-8 cycloalkenyl or optionally substituted aryl; provided that the total number of carbon atoms in R1 and R2 is an integer from 5 to 40 inclusive; the use of a compound of formula (I) (i) as an adjuvant provided that the total number of carbon atoms in R1 and R2 is an integer from 5 to 40 inclusive; and (ii) as a solvent provided that the total number of carbon atoms in R1 and R2 is an integer from 5 to 20 inclusive; to certain novel compounds of formula (I) and to a process for preparing those novel compounds.

  • Publication number: 20110166023
    Abstract: The present invention relates to an herbicidal composition comprising a. at least one ALS-inhibiting herbicide; b. at least one HPPD-inhibiting herbicide; c. at least one saturated or unsaturated fatty acid. The present invention further relates to a method of controlling weeds at a locus which comprise applying to the locus a diluted herbicidal composition according to the present invention. The present invention further relates to the use of a saturated or unsaturated fatty acid to chemically stabilise an herbicidal composition comprising at least one sulfonylurea herbicide and at least one HPPD-inhibiting herbicide.

  • Patent number: 7501094
    Abstract: The invention is an automated robotic system for the production and testing of formulations at a very high throughput. It is an integrated system of hardware and software capable of preparing and evaluating hundreds of emulsions per day. The system can formulate aqueous solutions (SL), oil in water emulsions (EW), suspo-emulsions (SE), micro capsule suspensions (CS), micro-emulsions (ME), and suspension concentrates (SC) at the 1 ml to 25 ml scale. The system can process emulsions rapidly in an automated way and enable very flexible formulation recipes to be introduced. The system allows chemists to generate experimental samples of varying recipe and method to be conducted in parallel with projected throughput of up to 1200 formulations processed and characterized per day. Materials and consumables can be distributed from storage storage systems to the work stations where dispensing of ingredients in various states can be performed, including solids, liquids, gels, pastes, suspensions and waxes.

  • Patent number: 7241454
    Abstract: Aqueous pesticidal suspensions comprise: (a) 5 to 40% w/v of (i) a pesticide having a melting point in the range of from 50 to 120° C. and a solubility in water of not more than 0.2% w/v or (ii) a mixture of the pesticide (i) and one or more other pesticides having a melting point of at least 50° C. and a solubility in water of not more than 0.2% w/v in the ratio of at least 1 part by weight of the pesticide (i) to 10 parts by weight of the other pesticide or pesticides, (b) 2.5 to 20% w/v of a non-ionic alkoxylate surfactant, (c) 0.5 to 5% w/v of a naphtalene sulphonate-formaldehyde condensate, (d) 0.1 to 5% w/v of a non-ionic polymethyl methacrylate-polyethylene oxide graft copolymer, (e) 0 to 25% w/v of other additives, and (f) water in sufficient amount to bring the total composition to 100% w/v. Pesticidal suspensions formulated in this way show less variation in viscosity than hitherto.
