dicamba acid 360 g/l + chlorsulfuron acid 22.2 g/lPostemergence herbicide intended to control annual bilobate weeds, including 2,4-D and MCPA resistant weeds, and some perennial bilobate weeds on cereal (wheat, barley, oats, rye) and common flax and oilseed flax plantings.
- Proprietary formulation of a widely known combination of two active ingredients with a bioactivator;
- Widest spectrum of action;
- Maximum efficiency with minimum cost of treatment per 1 ha;
- Prolonged application timing - until cereal evolving into tube;
- Recommended for autumn treatment of winter crops;
- Allowed for aerial treatment;
- Suitable for all agroclimatical zones of Russia and CIS-states.
Mechanism of action
Dicamba affects growth processes in sensitive weeds. Chlorsulfuron affects acetolactate synthase enzyme responsible for synthesis of amino acids.
Depending on soil and climatic conditions, species composition and growth phase of weeds, cereal crop plantings are freed from weeds after preparation application for 30 to 60 days or more.
Speed of action
The preparation penetrates weeds in a step-by-step manner within 4 hours. Weeds cease growing during the first day after treatment. The first signs of weed inhibition (twisting of leaves, damage to the top of stalks, whitening of the growing point) may be visually observed in 15 days depending on weather conditions.
Range of inhibited weeds
Annual bilobate weeds, including 2,4-D and MCPA resistant weeds, and some perennial bilobate weeds:
Sensitive species: ragweed, Canadian thistle, bluebottle, pepper plant (species), charlock, black bindweed, tansy mustard, common fumitory, satin flower, velvetleaf, spring groundsel, common orach, pigweed (species), dandelion (species), houndsberry, caseweed, hemp nettle (species), catch weed, field chamomile, wild radish, mayweed, bladder campion, sandweed, horehound, amaranth (species), dish mustard, day-nettle.
Moderately sensitive species: speedwell (species), corn bindweed, sheep bur, copper rose, milkweed, field scorpion grass, sow thistle (species), green ginger, spurge, houndsberry, green ginger, Sigesbeckia pubescens, field pansy.
Feebly sensitive species: barnyard grass, foxtail grass, loose silky bent, rough-stalk blue grass, foxtail (species).
Fenizan is compatible with other herbicides, fungicides and insecticides. Before use, check for physical and chemical compatibility of formulations.

Application technique. Mix preparation method
Prepare the mix and fill the sprayer on dedicated sites that are disinfected afterwards.
For ground treatment:
Fill the sprayer tank with water to about 1/2, then add the required preparation dose. Rinse the empty container twice and pour water into the sprayer tank. Top up with water until full and stir thoroughly.
For aerial treatment:
Fill the An-2 refilling unit tank with water to 1/2, add the required preparation dose and top up the tank with water until full while continuously stirring it.
As the aircraft approaches the area of treatment, turn the hydraulic agitator on to additionally stir the mix (hydraulic agitator working time min. 2 minutes).
Mix preparation and filling into sprayers tanks of an An-2 plane shall be carried out with engine stalled and additional mix cleaning using ground-based filters.
When using a Mi-2 helicopter provided with a dedicated refilling unit, the mix shall be loaded on a fenced site without main rotor stalling, but at reduced speed.
- For ground treatment – ground-based boom sprayers OPSh-15-01, OP-2000-2-01 or similar.
- For aerial treatment – An-2 plane or Mi-2 helicopter.
The best result and quickest herbicide action of the preparation are achieved by:
- treatment of plantings in the morning or evening at ambient temperature of 8⁰C to 25⁰C (5⁰C to 10⁰C in autumn), wind speed of max. 3 m/sec (in case of cloudy, but not rainy weather, spraying may be performed throughout the day);
- time from treatment until rain – min. 4 hours;
- at earlier stages of weed growth.
The following must not be done:
- treatment of plantings immediately before rain (time from treatment until rain – min. 4 hours) and after it;
- treatment of plantings after frost and strong heat (over 25⁰C);
- retreatment of plantings.
The preparation virtually does not inhibit cereal crops. The preparation has no phytotoxic effect on further plants in case of crop rotation.
Recommendations on protection of valuable flora and fauna objects
The preparation is virtually of no hazard to bees – Hazard Class 3.
Basic provisions of the ‘Guidelines for preventing bee poisoning with pesticides’ and following environmental regulations:
treat plants in morning and evening.
For ground application:
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 – 5-6 hours.
For aerial application:
treat plants at wind speed of 0 m/sec;
protection boundary zone for bees – min. 5-6 km;
bee’s flight time limitation – 5-6 hours.
Warn apiary owners 4 or 5 days before treatment.
The preparation may be used within the sanitary zone of fishery water bodies.
Transport and storage conditions
Comply with all conventional rules of toxic substance transport. Keep the preparation in a room dedicated for pesticide storage. Storage temperature range - minus 30⁰C to plus 30⁰C. Stir before use
