Click here for a printable version of this file

SECTION I - CLASS DEFINITION

STATEMENT OF CLASS SUBJECT MATTER

This class provides for compositions for treating living terrestrial and aquatic plants or their habitats for the purpose of stimulating or inhibiting growth, or any regulating action on plant growth, and the processes of using such compositions or compounds, per se, for such purposes which are not more than their mere application to the plant or habitat. The compositions or compounds included in this class will alter the plant growth through a chemical modification of the plant metabolism.

This class also provides for: (1) Seeds coated or impregnated with agricultural chemicals other than fertilizers, e.g., antidotes, plant growth regulators, micro-organisms, fungicides, disinfectants, etc. (2) Processes and their products which are of definite fertilizer value and are also insecticides, fungicides, or deodorants. These patents are cross-referenced to Classes 424 and 514. (3) Antidotal compositions, i.e., compositions which contain compounds capable of protecting cultivated plants from being damaged by herbicidal chemicals without affecting the herbicidal action of said chemicals against the weeds or unwanted plants to be controlled. (4) Soil life extenders, i.e., compositions which contain a herbicide and a compound useful for extending the soil life of said herbicide. (5) Compositions for preserving cut flowers. (6) Compositions for stimulating or increasing the sprouting of seeds, roots, tubers, or bulbs. (7) Compositions for regulating aquatic plants, particularly algae. (8) Compositions for regulating plant growth which use micro-organisms or products derived therefrom.

CLASSIFICATION GUIDELINES FOR THIS CLASS

In this class the chemical structure of the ingredient disclosed as having a utility set forth in the Statement of Class Subject Matter, above, is used as the primary basis of classification. Processes of using compositions or compounds, per se, and processes of making compositions, not provided for elsewhere are classified in the first appearing subclass providing for the particular active ingredient being employed or prepared.

The subclasses drawn to plural active ingredients include compositions which contain two or more active plant growth regulating agents, e.g., two or more herbicides.

No weight is given to a synergist or potentiator agent in classifying a composition for this class unless the synergist or potentiator agent is also an active plant growth regulator.

A patent claiming a Class 504 active ingredient broadly in terms of its function in combination with a specific adjuvant or carrier has been classified as original in the first appearing subclass providing for any one of the disclosed specific active ingredients and cross-referenced to all other subclasses providing for the remaining disclosed active ingredients.

	This subclass is indented under subclass 360.  Subject matter wherein the solid resin is derived only from one or more monomers of the formula: R1HC=CHR2, wherein R1 and R2 are H or organic radicals. (1) Note. Natural rubbers are included in this subclass. (2) Note. A resin derived from an ethylenically unsaturated monomer is assumed to be solid, unless stated otherwise.

362	Liquid carrier containing (e.g., water, hydrocarbon, etc.):
	This subclass is indented under subclass 358.  Subject matter wherein the designated nonactive ingredient is a liquid carrier, which carrier may be a liquid or a mixture of liquids, which liquids may be organic or inorganic.

363	Emulsion or foam (i.e., liquid continuous phase, and liquid or gas discontinuous phase):
	This subclass is indented under subclass 362.  Subject matter wherein a continuous liquid phase is present, and (a) a discontinuous gas phase is present for a foam, or (b) a discontinuous liquid phase is present for an emulsion. (1) Note. The emulsion may be water continuous- organic discontinuous, or water discontinuous-organic continuous phases. An emulsifier is usually present to stabilize the emulsion. SEE OR SEARCH CLASS: 516,  Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting,   subclasses 10 through 19, for foams, per se, and subclasses 9 and 20-76, for emulsions, per se.

364	Emulsifier or foaming agent containing a sulfonic acid, a metal salt thereof, or an unsubstituted or n-monosubstituted amide thereof:
	This subclass is indented under subclass 363.  Subject matter wherein an emulsifier or foaming agent of the formula R1S02R2, wherein R1 is MO, or R3NH, M is H or a metal, R3 is an organic radical or H, and R2 is an organic radical, is present to stabilize the foam or emulsion.

365	Organic nitrogen containing solvent, emulsifier, or foaming agent of formula R1N(R2)2 :
	This subclass is indented under subclass 363.  Subject matter wherein an organic solvent, emulsifier, or foaming agent present is of the formula R1N(R2)2, wherein R1 is an organic radical, and R2 is H or an organic radical. (1) Note. The nitrogen may be a member of a hetero ring.

366	Gel (i.e., a colloidal solution of a liquid in a solid):
	This subclass is indented under subclass 362.  Subject matter wherein the plant growth regulant is incorporated in a gel. (1) Note. Examples of gelling agents include, but are not limited to, polysaccharides, proteins, and silica. SEE OR SEARCH CLASS: 516,  Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting,   subclasses 98 through 112for gels, per se.

367	Granular or pulverulent designated nonactive ingredient containing:
	This subclass is indented under subclass 358.  Subject matter wherein the final form of the composition is granular (grainy), or pulverulent (fine powder or dust). (1) Note. Examples of inert ingredients proper for this subclass include, but are not limited to, clays, and other inert carriers, wetting agents, etc.
