P R I m m e R. In the following examples on the application of the subjects, the plants were placed in pots in the greenhouse.

Applying diluted in water concentrates was carried out after reaching monocotyle plants Apera Spicaventi, Friticum aestivum, Horoleum vulgare development stage 3 - 4 leaves and dicotyle plants Chenopodium album u Horoleum vul, 5-10 cm

After 4 weeks was assessed activity (damaged). The table shows the results of the experiments.

Synergism was demonstrated from a comparison of the additive degree of activity, calculated from the activities of the individual components according to the formula Colby with experimentally found by the degree of activity of the combination of active substances.
