Chemical Properties

yellow crystalline powder

Uses

Fluoroimide is used to control Monilinia mali and Mycosphaerella pomi in apples, Diaporthe citri and Elsinoe fawcetti in citrus, Corticium spp. in rubber trees, Botryfis cinerea and Peronospora destructor in onions, Colletotrichum theae-sinensis and Exobasidium vexans in tea, Phytophthora infestans in potatoes at 2-5 kg a.i. ha^-1 and Cercospora kaki and Mycosphaerella mwae in persimmons at 0.5-2 kg ha^-1.

Definition

ChEBI: A maleimide that is substituted at positions 3 and 4 by chlorines and on the nitrogen by a p-fluorophenyl group. Previously used as a fungicide (now obsolete).

Metabolic pathway

Fluoroimide is a relatively volatile solid with a high melting point. It degrades to a range of products in soils and plants. The main pathways are hydrolysis of the amide bond causing scission of the maleimide ring and stepwise reduction involving dechlorination of the maleimide ring. Little transformation of the parent fungicide occurred on plants.

Degradation

Hydrolysis of fluoroimide is base catalysed. The DT₅₀ values for the hydrolysis are 52.9,7.5 and 1.4 minutes at pH 3,7 and 8, respectively. The fungicide is stable to sunlight (PM).
