Preemergence and postemergence control of broad-leaved weeds in parsley, carrots,
dill and celery.
MONALIDE is used to destroyweeds of crops such as carrots, celery, and parsley.
The industrial synthesis of monalide involves the formation of a simple aliphatic amide structure. The process typically starts with pentanoic acid or its acid chloride, which is reacted with an appropriate amine under controlled conditions to form the amide bond. This reaction is carried out in organic solvents such as acetone or toluene, with temperature and pH carefully regulated to ensure high yield and purity. After synthesis, the crude product is purified through crystallisation or solvent extraction.
ChEBI: Monalide is an anilide.
Selective, systemic, absorbed through foliage. Inhibits cell division.
Biological. In the presence of suspended natural populations from unpolluted aquatic
systems, the second-order microbial transformation rate constant determined in the laboratory
was reported to be 6 ′ 10–13 L/organisms-hour (Steen, 1991).
Soil. Probably degrades via ring hydroxylation and subsequent ring cleavage. Persistence
in soil is limited to approximate 6–8 weeks (Hartley and Kidd, 1987). Under
laboratory conditions, the half-lives in soil were 30, 48 and 59 days at pH 4.85,
