Shtefam, KS

Active substance: phenmedipham, 160 g/l, desmedipham, 160 g/l

PURPOSE: Selective two-component herbicide for the control of annual dicotyledonous and some grass weeds on sugar beet crops.

PRINCIPLE OF ACTION: It has a contact effect, penetrates into plants through the leaf apparatus, blocks the process of photosynthesis. High air temperature (but not higher than 25°С) and intense solar radiation increase its effect. Does not affect weeds that have sprouted after treatment.

ADVANTAGES: a wide spectrum of action against weeds;
soil temperature and humidity do not affect efficiency;
possibility of use in tank mixtures with other drugs;
lack of influence on subsequent crops in crop rotation; flexibility in application due to the possibility of adjusting the application rate, depending on the degree of weeding of crops; lack of influence on subsequent crops in the crop rotation.

APPLICATION FEATURES: Must be used with Stemat 500, CS (etofumesate, 500 g/l). To increase the efficiency of Shtefam, KS is recommended to be used with both surfactants: +Ripo (at the rate of 0.5 l/100 l of working solution) and +Shtilvet Super (at the rate of 0.05 l/100 l of working solution). For extended control of the spectrum of dicotyledonous weeds, it is advisable to use in tank mixtures with drugs:
Goal (metamitron, 700 g/l);
Shteferib (triflusulfuron-methyl, 500 g/kg).
Compatible with drugs produced by DDE FARM AG. When using with drugs from other manufacturers, it is necessary to conduct a preliminary check on the compatibility of the components and the phytotoxicity of the mixture.

APPLICATION REGULATIONS: The drug cannot be used on hot days with strong solar radiation or when there is a danger of night frosts, as well as in crops of sick or weakened plants, as beetroot damage is possible!
It is recommended to carry out spraying at temperatures from +8 to +25 ºС using ground equipment in the morning (before 10) and evening (after 18) hours with minimal air flows. The air speed during fine-droplet spraying should not exceed 3 m/s, with large-droplet spraying - 4 m/s. Spraying of crops should be carried out in the phase of 2-4 true leaves of the culture at the rate of drug consumption of 5 l/ha - once. Or multiple times: the first spraying in the cotyledon phase of weeds, and the following - with an interval of 5-7 days.

CONSUMPTION STANDARDS OF WORKING SOLUTION: 200-300 l/ha
