General description

Isoprothiolane is a systemic fungicide, which is used in controlling diseases rice stem rot, rice blast and Fusarium leaf spot on rice. Its mode of action basically involves the inhibition of penetration and elongation of infecting hyphae via inhibiting the formation of infecting peg or cellulose secretion.

Application

Isoprothiolane may be used as a reference standard in the determination of isoprothiolane in food samples using gas chromatography coupled with mass spectrometry (GC-MS).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

The fungicide isoprothiolane (diisopropyl 1,3-dithiolan-2-ylidenemalonate) decomposed slowly in deionized water under ultraviolet light or sunlight irradiation. Rice-paddy water greatly accelerated the photodegradation. This photosensitizing effect was comparable to that of 2% acetone. Soil extracts, rice-plant extracts, and chlorophylls showed little

Low-cost magnesium- and/or carbon-based materials have a great potential to remove soluble contaminants from surface and ground water.
