Post-emergence systemic herbicide for the eradication of annual dicotyledonous and some grass weeds in sugar beet crops
Active substances Desmedifam, 71 g/l; Fenmedifam, 91 g/l; Etofumate, 112 g/l
Formulation Emulsion concentrate
Application spectrum Sugar beet, table and fodder crops
Main advantages
High efficiency and safety for the crop
Expanded spectrum against difficult-to-control weeds, especially such as pigweed and docks
Has a long residual effect
Optimal ratio of three active substances in one formulation
High selectivity
Better penetration of the active substance into plant tissues and rapid uptake by the plant
Ecologically safe, decomposes in soil within two months
Maximum effect can be achieved with 3 applications at a rate of 1 l/ha at early weed development stages (cotyledon phase). Minimum concentration of working solution is 0.4%. Optimal amount of working solution per hectare — 200 liters.
Herbicide efficacy depends on weed density and species composition, their age and physiological state. After the cotyledon stage in dicotyledonous weeds and the coleoptile stage in grass weeds, control becomes weaker. On hot days, spraying should be conducted in the evening and at night, ending spraying at least 6 hours before the temperature reaches +24 ºC.
Time before people can return to treated areas for mechanized work — 3 days; for manual work — 7 days.
Maximum number of applications — 3.
Mode of action
Active substances — desmedifam and fenmedifam act on emerged weeds through their leaves. High air temperature and intense sunlight enhance their activity. Soil temperature and moisture do not affect their efficacy. Etofumate is absorbed by various parts of the plant, especially young shoots, when they come into contact with the aqueous solution of etofumate in the soil. Therefore, higher soil moisture increases etofumate’s efficacy, while drought and high organic matter content in the soil reduce it.
Spectrum of activity
Annual grass weeds: annual meadow grass.
Annual dicotyledonous weeds: common henbane, medicinal camomile, common starwort, white hawkweed, field forget-me-not, field violet.
Biennial weeds: blue chicory.
Annual winter weeds: Persian speedwell, field mustard, stinging nettle, wild radish, field rape.
Compatibility with other products
In tank mixtures, the herbicide is compatible with most pesticides. However, compatibility must be checked for each specific case.
WHO classification: Class III (moderately hazardous).
