Definitions

  • the present invention relates to a method of controlling weeds. More particularly, the present invention relates to a method of controlling annual weeds using a herbicidally effective amount of maleic hydrazide.
  • Maleic hydrazide has a plant growth regulating action and is known as a potato growth inhibitor, but its mechanism of action is uncertain. It belongs to the pyridazinedione class. It is recommended for temporary growth inhibition of various shrubs and grasses. In acute toxicity studies, maleic hydrazide was found to be "practically nontoxic" to birds, fish, invertebrates, and honeybees, since it is mobile, but not persistent in environment. The use of maleic hydrazide or its salts in accordance with approved labeling will not pose unreasonable risks or adverse effects to the environment.
  • Maleic hydrazide or its salt is widely used for controlling perennial weeds such as curly dock, butterbur, hedge bindweed, wormwood, common sorrel, Japanese knotweed, red garlic and dandelion.
  • MH or its salt is used in the growth period of perennial weeds, that is, in spring or summer, a highest effect is attained by a method in which a terrestrial stem or leaf portion is cut off after passage of about 7 to about 10 days from the time of the chemical treatment. In practice, it is necessary that MH should be applied at a high rate. It is often difficult to obtain the intended controlling effect stably. Therefore, there is a lack of literature in the art that provides for a method that is convenient, economically beneficial, and efficient for control of weeds by application of maleic hydrazide.
  • the present disclosure provides a method of controlling annual weeds at a locus in soyabean crop cultivations comprising applying at said locus a herbicidally effective amount of maleic hydrazide in an amount ranging from 100 to 3000 g ai/ha.
  • maleic hydrazide or a salt thereof are meant maleic hydrazide, choline maleic hydrazide, diethanolamine maleic hydrazide, sodium maleic hydrazide and potassium maleic hydrazide.
  • herbicide as used herein means an active ingredient that kills, controls or otherwise adversely modifies the growth of plants.
  • a herbicidally effective or vegetation controlling amount is an amount of active ingredient that causes a “herbicidal effect,” i.e., an adversely modifying effect and includes deviations from natural development, killing, regulation, desiccation, retardation, and methods known to a person skilled in the art.
  • plants and “vegetation” include, but are not limited to, germinant seeds, emerging seedlings, plants emerging from vegetative propagules, and established vegetation.
  • locus of a crop/plant shall denote the vicinity of a desired crop in which weed control, typically selective weed control is desired.
  • the locus includes the vicinity of desired crop plants, wherein the weed infestation has either emerged or is yet to emerge.
  • g a.i./ha denotes the application amount of the respective active ingredient in “grams” applied “per hectare” of the crop field.
  • g ai/ha denotes the application amount of the respective active ingredient in “grams” applied “per hectare” of the crop field.
  • g ai/ha denotes the application amount of the respective active ingredient in “grams” applied “per hectare” of the crop field.
  • g ai/ha g a.i./ha
  • g/ha may be used interchangeably.
  • the present inventors felt the need to provide a method using maleic hydrazide to control broad spectrum weeds.
  • the inventors have specifically arrived at the application of maleic hydrazide for control of annual weeds in soyabean crop cultivations.
  • the application of maleic hydrazide also provides for reduction in toxicity in crops.
  • the present inventors have successfully provided a method of controlling such dense annual weeds.
  • the present invention provides a method for effectively controlling annual weeds at a locus comprising applying at said locus a herbicidally effective amount of maleic hydrazide.
  • the present disclosure provides a method for effectively controlling annual weeds growing in the locus of durum wheat and other wheat species, rice, oats, rye, barley, and maize.
  • the present disclosure provides a method for effectively controlling annual weeds growing in the locus of a crop, comprising applying maleic hydrazide at pre or post emergence of weeds at said locus in an amount ranging from 500 to 2500 g ai/ha.
  • the present disclosure provides a method for effectively controlling Eleusine indica weeds growing in the locus of soyabean crop, comprising applying maleic hydrazide at pre or post emergence of weeds at said locus in an amount ranging from 500 to 2500 g ai/ha.
  • the dosage level of maleic hydrazide may be defined by the inherent efficacy of the compound, the pest pressure, soil type, the weather, the formulation type and many other indeterminate variables. These standard dosage levels are fixed by the regulatory authorities.
  • constituents of the combination of the present disclosure may be applied in such quick succession in any order to form the desired mix at the locus of application.
  • combination of the present invention may be applied either pre or post emergent stages.
  • the advantage of the combination is surprisingly good residual effects, when applied in post-emergent leading to quick control of weeds.
  • They can be solids, such as, for example, dusts, granules, water-dispersible granules, microcapsules or wettable powders, or liquids, such as, for example, emulsifiable concentrates, solutions, emulsions or suspensions, ZC formulations. They can also be provided as a pre-mix or tank mixes.
  • Suitable agricultural adjuvants and carriers may include, but are not limited to, crop oil concentrates; methylated seed oils, emulsified methylated seed oil, nonylphenol ethoxylate; benzylcocoalkyldimethyl quaternary ammonium salt; blend of petroleum hydrocarbon, alkyl esters, organic acid, and anionic surfactant; C 9 -C n alkylpolyglycoside; phosphated alcohol ethoxylate; natural primary alcohol (C 12 -C 16 ) ethoxylate; di-sec- butylphenol EO-PO block copolymer; polysiloxane-methyl cap; nonylphenol ethoxylate, urea ammonium nitrate; tridecyl alcohol (synthetic) ethoxylate (8EO); tallow amine ethoxylate ; PEG(400) dioleate-99, alkyl sulfates, such as diethanolammonium lauryl sul

  • compositions of the present invention may be presented in the form of a multi-pack herbicidal product or as a kit-of-parts for treatment of targeted weeds.
  • the present disclosure provides use of maleic hydrazide for controlling annual weeds at pre-emergence or post emergence of said weeds.
  • the present disclosure provides for controlling annual weeds in soyabean crop cultivations, such weeds include Commelina, Commelina benghalensis, Euphorbia geniculate, Brachiaria sp, Dinebra sp, Dinebra arabica, Eleusine sp, Eleusine indica, Digitaria sp, Digitaria sanguinalis, Echinochloa sp, Echinochloa crus galli, Echinochloa colona, Cyperus iria, Phyllantus niruri, Parthenium hysterophorus, Parthenium sp, Setaria sp, Setaria viridis, Setaria verticullata, Acalypha sp, Acalypha indica, Dactyloctenium sp, Dactyloctenium aegyptium, Eragrostis sp, Eragrostis capillaris and other annual weeds.
