Assessment of urea impact on some physical and chemical characteristics of insecticides working solutions
If during this period Korahen and Konfidor solutions evaporated without additives by 24 and 31 % respectively, the mixture of Сarbamide evaporated by 9 % only. The figure was 78 and 64 or 28 % and 29 % respectively in 8 minutes. The water evaporated completely (100 %) within this period.
It has a good antievaporator effect since its addition to water emulsions and suspensions preparations results in reduced drops evaporation from the treated surface by more than 1.5 times.
