Herbicidal combination
The present invention relates to combinations of herbicides for controlling harmful undesirable plants. The present invention more specifically relates to a synergistic combination of herbicides, compositions and use of this composition for the preparation of a herbicide product and the method of application of said composition for combating weeds.
1 . A synergistic herbicidal combination for the control of weeds in agricultural crops consisting of:
a ternary mixture of active ingredients selected from the group consisting of:
a mixture of amicarbazone, isoxaflutole and atrazine,
a mixture of amicarbazone, clomazone and diuron,
a mixture of amicarbazone, S-metolachlor and atrazine,
a mixture of amicarbazone, sulfentrazone and diuron, and
a mixture of amicarbazone, mesotrione and ametryn;
wherein the herbicidal combination provides synergistic control of one or more weeds.
2 . The combination as claimed in claim 1 , wherein said amicarbazone is present in a quantity ranging from 1.0% to 99.0%, by weight of total combination.
3 . A method for controlling undesirable weeds, comprising contacting a crop plant or a non-crop area in need of weed control or at risk of undesirable weeds with the herbicidal combination of claim 1 .
4 . The method as claimed in claim 3 , wherein the crop plant is selected from the group consisting of cereals, rice, maize, sorghum, sugar cane, cotton, canola, turf, barley, potato, sweet potato, sunflower, rye, oats, wheat, corn, soybean, sugar beet, tobacco, safflower, tomato, alfalfa, pineapple, and cassava.
5 . A method of application of the herbicidal combination as claimed in claim 1 , comprising selecting an area of an agricultural crop; and applying a sufficiently effective quantity of said herbicidal combination to plants in the area and/or directly to an environment or a location or a soil in the area.
6 . The method as claimed in claim 5 , wherein the herbicidal combination is applied as a pre-emergence treatment or a post-emergence treatment.
7 . The method as claimed in claim 5 , wherein the herbicidal combination is applied at an application rate of from 0.01 kg/ha to 10 kg/ha to the crop.
8 . The herbicidal combination as claimed in claim 1 , wherein the weed is selected from the group consisting of Amaranthus, Cyperus and, Brachiaria decumbens, Cenchrus echinatus, Eleusine indica, Digitaria insularis, Ipomoea grandifolia, Euphorbia heterophylla, Commelina benghalensis, Amaranthus viridis, Amaranthus spinosus, Acalypha indica, Commelina communis, Digera arvensis, Euphorbia geniculate, Portulaca oleracea, Parthenium hysterophrous, Phyllanthus maderaspatnesis, Bracchiria spp, Dactyloctenium ageptisian and Echinochloa colonum.
9 . The method as claimed in claim 3 , wherein said amicarbazone is applied in a range of 50 to 1000 g ai/ha for the control of the weeds.
