Definitions

  • This invention pertains to the use of the compound of Formula I and its agriculturally suitable salts for broad spectrum weed control in plantation crops.
  • the compound is methyl 2-[H[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]amino]-sulfonyl]benzoate.
  • Useful formulations of the compound of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly.
  • Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare.
  • High strength compositions are primarily used as intermediates for further formulation.
  • the formulations broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:
  • Active ingredient plus at least one of a Surfactant or a Diluent equals 100 weight percent.
  • Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.
  • Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed * , Dorland Books, Caldwell, New Jersey, but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts.
  • Typical liquid diluents and solvents are described in Marsden, “Solvents Guide,” 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0oC.
  • compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Patent 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See
  • the ingredients are blended, coarsely hammermilled and then air-milled to produce particles essentially all below 10 microns in diameter.
  • the product is reblended before packaging.
  • the ingredients are blended, hammer-milled and then moistened with about 12% water.
  • the mixture is extruded as cylinders about 3 mm diameter which are cut to produce pellets about 3 mm long. These may be used directly after drying, or the dried pellets may be crushed to pass a U.S.S. No. 20 sieve (0.84 mm openings).
  • the granules held on a U.S.S. No. 40 sieve (0.42 mm openings) may be packaged for use and the fines recycled.
  • Example 6 The active ingredient is dissolved in the solvent and the solution is sprayed upon dedusted granules in a double cone blender. After spraying of the solution has been completed, the blender is allowed to run for a short period and then the granules are packaged.

  • the ingredients are blended and ground together in a sand mill to produce particles essentially all under 5 microns in size.
  • the ingredients are combined and ground together in a sand mill to produce particles essentially all below 5 microns.
  • the product can be used directly, extended with oils, or emulsified in water.
  • the ingredients are blended and ground in a hammer-mill to produce a material essentially all passing a U.S.S. No. 50 screen (0.3 mm opening).
  • the concentrate may be formulated further if necessary.
  • the ingredients are thoroughly blended, coarsely hammer-milled and then air-milled to produce particles essentially all below 10 microns in size.
  • the material is reblended and then packaged.
  • the active ingredient is blended with attapulgite and then passed through a hammer-mill to produce particles substantially all below 200 microns.
  • the ground concentrate is then blended with powdered pyrophyllite until homogeneous.
  • the compound of this invention can be specially formulated with diluents and/or carriers and/or other pesticides for application to plantation crops.
  • the following list exemplifies some of the herbicides suitable for use in mixtures.
  • Common Name Chemical Name dalapon 2,2-dichloropropionic acid diuron 3-(3,4-dichlorophenyl)-1,1-dimethylurea

  • the compound employed in the method of the present invention is an active herbicide for selective broadleaf and grass weed control with safety to plantation crops such as coffee, cocoa, oil palm, rubber, banana, citrus and certain conifers.
  • Compound I can be applied as a preemergence or postemergence treatment using techniques of banding, directed sprays or broadcast applications.
  • the compound of this invention is used at 0.5 to 500 g/ha with a preferred rate range of 1 to 250 g/ha rate.
  • One skilled in the art can select the proper rates for a given situation.
  • the compound of this invention may be used in combination with other pesticides. It is particularly useful in combination with broadleaf herbicides used in plantation crops including: triazine, triazole, uracil, urea, amide, carbamate, bipyridylium, phenoxys, sulfonylurea and imidazolinone types.
  • broadleaf herbicides used in plantation crops including: triazine, triazole, uracil, urea, amide, carbamate, bipyridylium, phenoxys, sulfonylurea and imidazolinone types.
