Abstract
The invention relates to a new process for the preparation of stable aqueous suspensions of methyl N-(2-benzimidazolyl)carbamate. According to the invention an aqueous solution of an addition salt of methyl N-(2-benzimidazolyl)carbamate and an inorganic acid, optionally containing an excess amount of acid is reacted with an aqueous potassium, sodium or ammonium hydroxide solution or ammonia gas, in the presence of a wetting, dispersing and antifoaming agent and optionally of a protecting colloid at a temperature of 50.degree. C. to 100.degree. C., and if desired, the suspension obtained is concentrated or diluted. The suspension prepared by this process can either be used directly or can be supplemented with further additive(s) conventionally used in the preparation of plant protecting agents.
