Common Name FRAC1 Group Name Trade Name(s)2 Topical mode of action3 Excellent tank mix partner with most other fungicides. It is a broad spectrum systemic fungicide widely used in agriculture to protect crops from fungal diseases. 2. PROPICONAZOLE 41.8% EC FUNGICIDE belongs to the Group 3 class of fungicides which means that propiconazole acts as a demethylation inhibitor of sterol biosynthesis in the membranes of fungi. We coupled the results from genomic analyses with traditional laboratory investigations (toxicology, molecular biology and biochemistry) to propose a mode of action (MOA) for the carcinogenic activity of propiconazole in mouse liver. Propiconazole is a triazole fungicide, also known as a DMI, or demethylation inhibiting fungicide due to its binding with and inhibiting the 14-alpha demethylase enzyme from demethylating a precursor to ergosterol.Without this demethylation step, the ergosterols are not incorporated into the growing fungal cell membranes, and cellular growth is stopped.

Brz's mode of action is to bind and block DWF4/CYP90B1 .DWF4 is a P450 that mediates multiple rate-limiting C22 alpha-hydroxylations in the biosynthesis of BRs . MODE OF ACTION: Locally systemic mode of action for long-lasting disease control. Areas of compaction, poor soil drainage, excess thatch, or with large amounts of Poa annua favour the development of anthracnose. Chemical classes and modes of action of fungicides registered for use on turfgrasses . The microemulsion formulation of Propiconazole results in better tank stability and less odor. Its locally systemic mode of action allows for long-lasting disease control. Rotated with fungicides which have a different mode of action.

Propiconazole is perfect for nurseries, landscaping, turf, trees, golf courses, and tree injections. Resistance can develop whenever products with the same mode of action are used over and over in the same fields or crops. Azoxystrobin is a new fungicide with a novel biochemical mode of action. This document is PI94, one of a series of the Pesticide Information Office, UF/IFAS Extension. Here, we tested 2 triazole fungicides, propiconazole, and tebuconazole (Te), for individual and combined effects on liver toxicity-related endpoints.

Locally systemic mode of action for long-lasting disease control. Azoxystrobin is the ISO common name for an organic compound that is used as a pesticide.

 Anthracnose:  26–51:  21 days:  Apply when warm, humid weather conditions occur. Revised February 2009, November 2012, and October 2015. DWF4 expression is a target of regulation by both endogenous signals like auxin – and exogenous cues like temperature .Brz and its even more specific derivative Brz2001 became invaluable tools for BR research.

This product is an excellent tank-mix partner with most other fungicides. Substances with the same target organ, same toxic effect and same mode of action (MoA) are believed to cause additive effects, whereas substances with different MoAs are assumed to act independently.

A key element of the approach was … Its synthesis was inspired by a group of natural products, the strobilurins, which are produced by several species of Basidiomycete fungi, which grow on decaying wood. Sync Fungicide Activator is strongly recommended to use when spraying Propiconazole 14.3 Fungicide. It was first marketed in 1996 using the brand name Amistar and by 1999 it had been registered in 48 countries on more than 50 crops. Excellent tank mix partner with most other fungicides.

Do not apply more than 6 applications per season.
