Post-emergence herbicide for controlling major annual broadleaf and grass weeds in corn crops
Active ingredient: sulfonylurea derivatives
Manufacturer: Sinokem Hebei Corporation, China
Formulation: water-soluble granules
Packaging unit: 500 g
Spectrum of action of the preparation
By eliminating both annual and perennial broadleaf and grass weeds, including field bindweed (red sorrel), field mustard, species of chickweed, species of crabgrass, common hogweed, creeping cinquefoil, and flexible timing of application, the preparation can be applied according to specific production conditions.
Mode of action
The active ingredient of the preparation has a systemic mode of action. It is absorbed by the above-ground parts of plants, transported to apical meristems, where it blocks cell division processes.
Signs of herbicidal action
The first visible signs of the preparation's action on weeds (bleaching, growth inhibition, shoot tip death) appear on day 3-5, which is related to the specific mode of action of the preparation. Complete weed death occurs over a period of 2-3 weeks.
Crop growth stage
The preparation is applied when corn plants are in the 1-7 leaf stage.
Weed growth stage
Maximum efficiency of the preparation is observed when applied during active weed growth and development:
— perennial grass weeds (creeping cinquefoil, goosegrass) — at a height of 10-15 cm;
— annual grass weeds (species of crabgrass, common barnyard grass (wild millet) — in the 1-3 leaf stage;
— annual broadleaf weeds — in the 2-4 leaf stage.
Weather conditions
The preparation is applied at average daily air temperatures of +10… 25°C. Application of the preparation at low (below +10°C) or high (above +25°C) air temperatures may cause phytotoxicity to crop plants. Rainfall within 4 hours after application may significantly reduce the efficacy of its action on weeds.
Application of the herbicide Maitus under dry conditions
The working solution dosage should be at least 300 L/ha to ensure better wetting of weed plants. Herbicide Maitus is then added with ammonium fertilizers, followed by surfactants. The working solution dosage is 200-300 L/ha.
Recommended tank mixes
Application of herbicide Maitus in tank mixes with herbicides of the 2,4-D group significantly increases the effectiveness of eliminating such weeds as ragweed, common ragwort, field bindweed, white deadnettle, black nightshade, and others.
Preparation of the working solution
To prepare the working solution, fill the sprayer tank with water to 1/3 of its volume. Turn on the mixing mode and add the required amount of the preparation or its stock solution. Fill the sprayer tank to 3/4 of its volume, stop mixing, and add the required amount of surfactant into the working solution. Fill the sprayer tank to full volume and turn on the mixing mode again. During application, the mixing mode should remain on to maintain the working solution in a homogeneous state.
Precautions
— not recommended for use on sugar corn, popcorn corn, seed corn (parent line multiplication) crops;
— not recommended for use when crop plants exceed 7 leaves;
— do not apply herbicide Maitus on fields within 7 days before or after application of organophosphorus insecticides, as this may cause phytotoxicity to crop plants;
— mechanical tillage or harrowing within 7 days before or after application may significantly reduce the efficacy of its action on weeds;
— do not apply herbicide Maitus if the pH of the working solution is less than 4, including when adding tank-mix components.
