Betaren Super MD, OEC

Ethofumesate 126 g/l + phenmedipham 63 g/l + desmediphan 21 g/l

Overwhelming Advantage

Postemergence herbicide to control annual bilobate weeds, including amaranth, catch weed bedstraw, common chickweed, dish mustard, much weed, knotweed as well as some annual cereals - barnyard grass and green foxtail on the beet crops.

General information

Advantages

  • highly effective at reduced concentration of the active ingredient due to innovative preparative form OEC;
  • particles of the active ingredient in oil emulsion are at a fine state, thus providing highest stability and homogeneity of the sprayed solution, which promotes deep penetration of the preparation;
  • does not have phytotoxic action on the crop that raises the level of crop yield;
  • highly effective against annual bilobate and some cereal weeds at their early stages of development;
  • highly compatible as part of prepared mixtures with other herbicides to enhance the spectrum of action;
  • presence of ethofumesate penetrating through leaves and roots ensures a long-term beet protection from weeds.

Action

Mechanism of action
Due to its weed penetration features, oil emulsion concentrate provides significant improvement in herbicide absorption. Particularly, oil serves as a conductor of the active ingredient through the wax layer of a leaf and facilitates preparation penetration in deeper layers of a weed. Particles of the active ingredient in oil emulsion are at a fine state, thus providing highest stability and homogeneity of the sprayed solution, which promotes deep penetration of the preparation; when applied on a weed, oil emulsion distributes evenly and forms a film on the leaf surface preventing preparation evaporation and washing-off. This helps maintain preparation activity that does not depend on weather conditions.
The preparation impairs photosynthesis and protein metabolism in weeds. Phenmedipham and desmediphan penetrate through leaves and have a translaminar effect affecting photosynthesis. Ethofumesate penetrates roots and leaves and has a systemic effect impairing mitosis in cells of weeds.
Protective period
Protective period is determined by appearance of the second and third waves of weeds, which is dependent on weather conditions. The preparation affects weeds present in the plantings during spraying.
Speed of action
Visible signs of herbicide action appear depending on weather conditions on 4th to 8th day after application.
Spectrum of action
Annual bilobate and some cereal weeds.
Sensitive species: ragweed, speedwell (species), pepper plant (species), charlock, black bindweed, sheep bur, common fumitory, bur grass (species), satin flower, spring groundsel, common orach, pigweed (species), milkweed (species), rough-stalked bluegrass, field scorpion grass, houndsberry, caseweed, hemp nettle (species), catch weed, portulaca, wild radish, bladder campion, sandweed, field pansy, amaranth (species), dish mustard, day-nettle.
Moderately sensitive species: bluebottle, vetch, Aleppo grass, tansy mustard, velvetleaf, copper rose, loose silky bent, oat grass, sow thistle (species), green ginger, millet (species), crabgrass, foxtail (species).
Feebly sensitive species: Canadian thistle, sheepbine, foxtail, dandelion (species), ryegrass (species), field chamomile, quack grass, mayweed, quitch.
Compatibility
Compatible with a number of herbicides used at beet plantings (Furex, Pantera, Forward, Mitron, Lornet, etc.). Before use, check for physical and chemical compatibility.
Potential for resistance
No facts of resistance were observed when using herbicides based on ethofumesate, phenmedipham, and desmediphan.

Phytotoxicity
The preparation is selective enough to avoid exposure to sugar, table and fodder beet when used in line with the proposed regulations.
Phytotoxicity effect on beet plants may appear when applied at high ambient temperatures (above 25⁰C) and if the crop plants are under stress (frost, drought, etc.). Safe application hours for the herbicide are morning or evening.
Application technique.Mix preparation method
Prepare the mix immediately before use. Dose the preparation for a single fill of the sprayer. Then prepare the mix as follows: Fill the sprayer tank to about its half with water, add the required herbicide dose and top up with water until full while continuously stirring using hydraulic agitators. Rinse the empty tank several times with water that is then poured into the sprayer tank.
Prepare the mix and fill the sprayer on dedicated sites that are disinfected afterwards.
Use ground-based boom sprayers OPSh-15-01, OP-2000-2-01 or similar.
The best result and quickest herbicide action of the preparation are achieved by:
crop treatment at earlier stages of weed development;
crop treatment in the most favorable weather conditions. Optimal ambient temperature – max. 25⁰C. Do not apply on beet plantings weakened by frosts, heat, and pests.
Recommendations on protection of valuable flora and fauna objects
The preparation is of low hazard to bees and fish – Hazard Class 3.
Basic provisions of the ‘Guidelines for preventing bee poisoning with pesticides’ and following environmental regulations:
Plant treatment is to be performed as follows:
in the morning or evening at wind speed up to 4 to 5 m/sec;
protection boundary zone for bees – min. 2-3 km;
bee’s flight time limitation – 3-4 hours.
Warn apiary owners 4 or 5 days before treatment.
Do not use the preparation in private farms, by aerial method and within the sanitary zone of fishery water bodies 500 m away from the flood line in case of maximum floodwater level, but not closer than 2 km to the existing banks.
