Пример 1. Послевсходовое применение .Example 1. Post-harvest application.

Семена опытных растений высевали в специальные горшочки с почвой и выращивали до стадии 4-6 листочков. После этого растени  опрыскивали водными эмульси ми действующих веществ из расчета 4 кг/га по действующему веществу и выдерживали в услови х теплицы в течение 15 дней. Оценку гербищщного эффекта проводили по шкале;Seeds of experimental plants were sown in special pots with soil and grown to the stage of 4-6 leaves. After that, the plants were sprayed with aqueous emulsions of the active ingredients at the rate of 4 kg / ha for the active substance and kept in greenhouse conditions for 15 days. Evaluation of the herbal effect was performed on a scale;
