The peculiarity of the drug is rapid penetration into the system of weeds and blocking of growth processes. When processing the area, the cultivated crops are not only not damaged, but also stimulated by the bioactivator of growth contained in the prima donna.

The principle of action of the herbicide Primadonna ®.
The systemic activity of the drug ensures its rapid penetration into the plant system. Within an hour, the herbicide is absorbed by the plant, blocking growth processes.

Results:
The first results of treatment with prima donna herbicide can be seen within 3-4 days. Final destruction of weeds occurs after 2-3 weeks. The terms depend on weather conditions and the type of weeds. The growth of new weeds on the treated area stops on the first day after using the drug.

The validity period of the prima donna depends on several conditions:
• Rate of application of herbicide;
• Weather conditions;
• Type and susceptibility of weeds.

The maximum effectiveness of Primadonna ® is achieved when treating areas with weeds 5-10 cm high. For perennial weeds, the rosette phase is also an important factor.

Primadonna ® is a herbicide that is actively used in combination with other fungicides, herbicides, insecticides and growth stimulants. The main condition is to check the mixture for compatibility and phytotoxicity in relation to the cultivated crop.

The best combination and the highest biological efficiency is achieved only when using pesticides from CHEMISCHE GUTER AG in tank mixtures.

Recommended mixes:
Having an advantage over similar drugs, it is recommended to use, without restrictions, mixtures with Benazol, Titul DUO, Fascord, Kinfos according to the regulations of application by phases of cultivated crops.

In corn crops, in the 3-7 leaf phase, to expand the spectrum of weed control, for effective work in extreme conditions (heat, hot climate), it is recommended to use a tank mixture:

Possibility of resistance:
Florasulam is an inhibitor of the photosynthetic enzyme acetolactate synthase, 2,4-D causes an auxin-type reaction. This dual effect of the herbicide reduces the possibility of resistance in weeds.

It is recommended to mix the drug before use.(//tractor-service.com)
