Definitions

  • U.S. Patent 3,816,092, issued June 11, 1974, teaches the selective control of weeds in a variety of crops, including rice.
  • This reference teaches, Col. 1, lines 42-45, that herbicidally active agents cannot be predicted from the prior knowledge of compounds that have herbicidal activity.
  • the principal weed of rice is an annual grass, Echinochloa crusgalli. This grass and its close relatives are troublesome weeds in many countries of the world. Although a number of chemicals and techniques have been developed to attack this problem, there has not yet been a completely acceptable method for controlling such grassy weeds in the presence of desirable crops such as rice.

  • the invention also provides a method for selectively controlling grassy weeds in the presence of rice which comprises applying to the weeds at least a herbicidally effective amount, but less than an amount which is phytotoxic to the rice, of a compound of Formula I as set forth hereinabove.
  • the compounds employed in the method of the present invention are novel compounds and may be prepared using the requisite starting materials by the methods illustrated in the following Examples through VI.
  • This acid chloride was dissolved in 18 ml toluene and added to 1.65 g (.011 mole) of 2-amino-benzothiazole and 1.11 g (0.011 mole) triethylamine dissolved in 45 ml warm toluene.

  • 3-Amino-pyridine (1.1 g, 0.0117 mole) and triethylamine (2.3 g, 0.23 mole) were put in a 125 ml flat-bottomed flask, dissolved in toluene (25 ml), flushed with nitrogen and warmed to 62oC.
  • the acid chloride solution was added over a 6 minute period. During this time the temperature rose to 65oC.
  • the reaction mixture was then taken on up to reflux and refluxed for one hour and 50 minutes. At the end of this time the salt formed was filtered off and the toluene solvent was removed on a rotary evaporator.
  • the compounds utilized in the method of the present invention provide selective control of grassy weeds in rice (Oryza sativa), and give particular and advantageous selective postemergent control of Echinochloa crusgalli (commonly known as bamyardgrass or watergrass) in the presence of rice.
  • unmodified active ingredients of the present invention can he employed.
  • the present invention embraces the use of the compounds in composition form with an inert material known in the art as an agricultural adjuvant or carrier in solid or liquid form.
  • an active ingredient can be dispersed on a finely-divided solid and employed therein as a dust or granule.
  • the active ingredients, as liquid concentrates or solid compositions comprising one or more of the active ingredients can be dispersed in water, typically with aid of a wetting agent, and the resulting aqueous dispersion employed as a spray.
  • the active ingredients can be employed as a constituent of organic liquid compositions, oil-in- water and water-in-oil emulsions or water dispersions, with or without the addition of wetting, dispersing, or emulsifying agents.
  • Suitable adjuvants of the foregoing type are well known to those skilled in the art.
  • the concentration of the active ingredients in solid or liquid compositions generally is from about 0.0003 to about 95 percent by weight or more. Concentrations from about 0.05 to about 50 percent by weight are often employed. In compositions to be employed as concentrates, the active ingredient can be present in a concentration from about 5 to about 98 weight percent.
  • the active ingredient compositions can also contain other compatible additaments, for example, phytotoxicants, plant growth regulants and other biologically active compounds used in agriculture.
  • the compounds of the present invention or compositions containing the same can be advantageously employed in combination with one or more additional pesticidal compounds.
  • additional pesticidal compounds may be insecticides, nematocides, arthropodicides, herbicides, fungicides or bactericides that are compatible with the compounds of the present invention in the medium selected for application, and not antagonistic to the activity of the present compounds.
  • the pesticidal compound is employed as a supplemental toxicant for the same or for a different pesticidal use or as an additament.
  • the compounds in combination can generally be present in the ratio of from 1 to 100 parts of the compound of the present invention with from 100 to 1 parts of the additional compound(s).
  • the exact rate to be applied is dependent not only on a specific active ingredient being applied, but also on a particular action desired, the plant species to be modified and the stage of growth thereof as well as the part of the plant to be contacted with the toxic active ingredient.
  • all of the active ingredients of the present invention and compositions containing the same may not be equally effective at similar concentrations or against the same plant species.
  • a dosage of about 0.01 to about 20 pounds/acre (0.01122.4 kg/hectare) is generally applicable, although not all compounds are equally effective and some weeds are more difficult to control.
  • a dosage rate in the range of about 0.05 to about 1.0 pound/acre (0.056-1.12 kg/hectare) is preferred in postemergent control of annual grassy weeds, while about 0.5 to about 5 pounds/acre (0.56-5.6 kg/hectare) is a preferred dosage range for the postemergent control of perennial grassy weeds.
  • each compound to be utilized in a series of tests is dissolved in acetone to one-half of the final volume (twice the final concentration) to be used and the acetone solution in each case is admixed with an equal volume of water containing 0.1 percent by weight ⁇ f surface active material.
  • the compositions generally in the nature of an emulsion, were employed to spray separate respective plant species which had been grown to a height of 2-6 inches in soil of good nutrient content in a greenhouse. Sufficient amounts were employed to provide various application rates as listed in the table.
  • the various beds were positioned side by side and exposed to substantially identical conditions of temperature and light. Each bed was maintained so as to prevent any interaction with test compounds in different seed beds.
  • Control refers to the reduction in growth compared to the observed results of the same untreated specie. Note that "NT" means "not tested”.
  • Enantiomorphs often show the same biological effect but to a very different degree.
  • a general discussion of this phenomenon may be found in A. Albert, Selective Toxicity, 4th Ed. Met Luen & Co., Ltd., London, 1968, pp. 387-390 and more particular discussions in A. Fredga and B.
