Selective post-emergence herbicide for controlling annual broadleaf weeds and some perennial weeds on cereal and corn crops
Active ingredient: 2-Ethylhexyl ester of 2,4-D, 850 g/l, acid equivalent — 564 g/l
Manufacturer: Peters & Burg Ltd, Hungary
Formulation: concentrate emulsion
Packaging: 5 L, 20 L canisters
Mode of action
The active ingredient is absorbed through the above-ground parts of the plant and actively translocated throughout all organs. In sensitive weeds, it inhibits chlorophyll biosynthesis, which leads to a slowdown of photosynthesis. Acting on meristematic tissues, it disrupts weed growth and development, causing leaf and stem curling, root thickening, softening, and becoming watery, cracking, and eventually dying. Plants lose turgor, leaves lose color and turn yellow.
Characteristics and advantages
— The active ingredient in the form of 2-ethylhexyl ester of 2,4-D is rapidly absorbed by plants, so rain within one hour after application practically does not affect the efficacy of the product.
— High selectivity for crop plants provided that application guidelines are followed.
— Compatible with most pesticides and liquid fertilizers, but compatibility of individual components must be checked in each case.
Application recommendations
The product is applied via ground spraying during the vegetative stage from tillering to stem elongation for cereals, and from 3 to 5 leaves for corn. Maximum efficacy is observed when applied during active weed growth — stage 2-4 leaves for annual broadleaf weeds and rosette stage for perennial broadleaf weeds. Optimal spraying temperature is +12…+20°C. Spraying is prohibited if wind speed exceeds 3–4 m/s. First visible signs of the product’s action (chlorosis, loss of turgor, stem deformation) appear 2–5 days after application.
To prepare the working solution, fill the sprayer tank halfway with water, activate the mixing mode, add the required amount of the product. Then top up with water to full volume while the mixing mode is active. Recommended application rate: 200–400 L/ha.
For effective control of 2,4-D resistant weeds, the herbicide must be used in tank mixtures with products from the group of systemic sulfonylureas.
