Maximum effect, minimum cost
Fenizan, VR — post-emergence herbicide for controlling annual broadleaf weeds, including those resistant to 2,4-D and MCPA, and some perennial broadleaf weeds on cereal crops (wheat, barley, oats, rye) and flax.
Advantages
patented formulation of a widely known combination of two active ingredients; contains a bioactivator;
broadest spectrum of activity;
maximum efficiency at minimal economic cost per hectare;
extended application window — up to the emergence of cereal crops;
recommended for autumn application on winter crops;
approved for aerial application;
suitable for all agro-climatic zones of Russia and CIS countries.
Formulation
Aqueous solution containing 360 g/l dicamba (diethyl ethanolamine salt) + 22.2 g/l chlorosulfuron (diethyl ethanolamine salt).
Mode of action
Dicamba affects the growth processes of sensitive weed plants. Chlorosulfuron acts on acetolactate synthase — an enzyme responsible for amino acid synthesis.
Duration of protective effect
Depending on soil-climatic conditions of the region, weed species composition, and growth phase of weeds, cereal crops are free from weeds for 30 to 60 days or longer after treatment.
Speed of action
The product gradually penetrates weed plants over 4 hours. Weed growth stops within the first day after treatment. First visible signs of weed suppression (leaf curling, stem tip damage, growth point bleaching) appear within 15 days depending on weather conditions.
Spectrum of controlled weeds
Annual broadleaf weeds, including those resistant to 2,4-D and MCPA, and some perennial broadleaf weeds:
sensitive species: Ambrosia artemisiifolia, burdock, blue violet, docks (various), field mustard, creeping cleavers, Descurainia sophia, medicinal camphor, starwort, Teophrastrum, early mustard, milkweed, shepherd's purse, pica (various), common dandelion, black nightshade, field bindweed, common starwort, common ragwort, common sowthistle, common groundsel, common hawksbeard, common chickweed, common yarrow, common mallow, common cornflower, common wormwood, common phlox, common vetch, common thistle, common knapweed, common chickweed, common yarrow, common mallow, common cornflower, common phlox, common vetch, common thistle, common knapweed, common chickweed, common yarrow, common mallow, common cornflower, common phlox, common vetch, common thistle, common knapweed;
moderately sensitive species: Veronica (various), field bindweed, common ragwort, common sowthistle, common groundsel, common hawksbeard, common chickweed, common yarrow, common mallow, common cornflower, common phlox, common vetch, common thistle, common knapweed;
weakly sensitive species: burdock, foxglove, common chickweed, common vetch, common thistle, common knapweed.
Compatibility
Fenizan is compatible with other herbicides, fungicides, and insecticides. It is recommended to conduct a physicochemical compatibility test before application.
Potential for resistance development
Not detected.
Application technology. Preparation of working solution
Preparation of the working solution and tank filling are conducted on special areas, which are later subjected to decontamination.
For ground application.
Fill the sprayer tank halfway with water, then add the required amount of the product. Rinse the empty container twice and add water to the sprayer tank. Top up with water to full capacity and mix thoroughly.
For aerial application.
Fill the fuel tank of the Antonov An-2 aircraft halfway with water, add the required amount of the product, and top up with water to full capacity while mixing.
During approach to the treated area, activate the hydraulic mixer for additional mixing of the working solution (minimum 2 minutes of operation).
Preparation of the working solution and filling the tank of Antonov An-2 aircraft sprayers are conducted with the engine off, using ground filters for additional cleaning of the working solution.
For use with a Mi-2 helicopter equipped with a special refueling device, loading of the working solution is conducted on a fenced work area without stopping the main rotors, but at reduced RPM.
Recommended machine models:
for ground application — ground boom sprayers OPSh-15-01, OP-2000-2-01, etc.;
for aerial application — Antonov An-2 aircraft and Mi-2 helicopter.
Optimal results and maximum herbicidal effect are achieved:
application in the morning or evening at air temperatures of 8 — 25 °C (in autumn, 5 — 10 °C); wind speed not exceeding 3 m/s (on cloudy but not rainy days, spraying can be conducted throughout the day);
time from application to rain — not less than 4 hours;
at early stages of weed development.
Not allowed:
application immediately before or after rain (at least 4 hours before and 3 hours after application);
application after frost or under strong heat (above 25 °C);
repeated application.
Phytotoxicity
The product practically does not suppress cereal crops. It is not phytotoxic to subsequent crops in crop rotation.
