Iprodione
chemical compound
Iprodione is a hydantoin fungicide and nematicide.
Application
Iprodione is used on crops affected by Botrytis bunch rot, Brown rot, Sclerotinia and other fungal diseases in plants. It is currently applied in a variety of crops: fruit, vegetables, ornamental trees and shrubs and on lawns. It is a contact fungicide that inhibits the germination of fungal spores and it blocks the growth of the fungal mycelium.
It has been marketed under the brand name "Rovral" and "Chipco green" (both brands of Bayer CropScience). This chemical was developed originally by Rhône-Poulenc Agrochimie (later Aventis CropScience and in 2002 acquired by Bayer). As of 2004 there were no composition patents on iprodione.
DevGen NV (Now part of Syngenta) discovered that iprodione kills nematodes and filed for patent protection for those uses.
Iprodione was approved in the Turkish market under the brand name Devguard for use on tomatoes and cucumbers in 2009, and was approved in the US as Enclosure for use in commercial peanut production in May 2010.
Iprodione was approved in Europe in 2010, but approval was not renewed in 2017.

Why this record matters
“Iprodione” is worth following because a concise public description often conceals a longer documentary argument. Here, Iprodione, chemical and compound provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 20, 2026. The linked authority identifier is Q411542. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2002, 2004, 2009 and 2010.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
