phenmedipham 60 g/l + desmediphan 60 g/l + ethofumesate 60 g/lPostemergence 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 sugar, table (except loose products) and fodder beet plantings.
- 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;
- Fast herbicide action.
Mechanism of action
The preparation impairs photosynthesis and protein metabolism in weeds. Phenmedipham and desmediphan penetrate through leaves and have a translaminar effect, thereby preventing photosynthesis. Ethofumesate penetrates roots and leaves and has a systemic effect impairing mitosis in cells of weeds.
Until 2nd wave of weeds.
Speed of action
Weeds stop growing during the first day after treatment. Visible signs of herbicide effect on weeds appear in 3 or 4 days after treatment.
Spectrum of action
Annual bilobate and some cereal weeds.
Sensitive species: ragweed, speedwell (species), pepper plant (species), charlock, knotweed, sheep bur, common fumitory, bur grass (species), satin, spring groundsel, common orach, pigweed (species), rough-stalked bluegrass, field scorpion grass, houndsberry, caseweed, hemp nettle (species), catch weed, 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, green ginger, millet (species), crabgrass, foxtail (species).
Feebly sensitive species: Canadian thistle, sheepbine, foxtail, sow thistle (species), dandelion (species), ryegrass (species), field chamomile, quack grass, mayweed, quitch.
Use as part of prepared mixes to enhance the spectrum of action. Compatible with a wide number of herbicides, such as Furex, Lornet, Pantera, Healer, Forward, Mitron and others used on beet plantings. Before use, check for physical and chemical compatibility.
Potential for resistance
No potential for resistance is revealed.

Application technique. Mix preparation method
Prepare the mix immediately before use. Dose the preparation for a single fill of the sprayer. Prepare in advance a concentrated emulsion of the preparation in a separate vessel. Fill the vessel to 1/4 of its volume with water, add the preparation dose, stir thoroughly, top up with water to 3/4 of volume (stock solution concentration – 50-70% of preparation). Then prepare the mix as follows: Fill the sprayer tank to about its half with water, add the concentrated preparation emulsion and top up with water until full while continuously stirring the mix using mechanical agitators. Rinse the vessel where concentrated emulsion was prepared with water several times.
When using prepared herbicide mixes, these shall be prepared in line with the recommendations for each particular preparation. Do not add other preparations to the concentrated emulsion (stock solution).
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.
Potential phytotoxicity effect on beet plants may appear when applied at high ambient temperatures (above 25⁰C) and if the plants are under stress (frost, drought, etc.). Safe application hours for the herbicide are morning and evening.
Recommendations on protection of valuable flora and fauna objects
The preparation is of low hazard to bees – Hazard Class 3. Basic provisions of the ‘Guidelines for preventing bee poisoning with pesticides’ and following environmental regulations:
- treat plants at wind speed up to 4 or 5 m/sec;
- protection boundary zone for bees – min. 2-3 km;
- bee’s flight time limitation – 3-6 hours.
Warn apiary owners 4 or 5 days before treatment.
Do not apply the preparation 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.
Transport and storage conditions
Comply with all conventional rules of toxic substance transport. Keep the preparation in a dry room dedicated for pesticide storage. Storage temperature range – minus 10⁰C to plus 35⁰C. Stir before use
