Propiconazole
   
Introduction: Propiconazole is a systemic foliar fungicide with a broad range of activity.
It is used on grasses grown for seed, mushrooms, corn, wild rice, peanuts, almonds, sorghum,
oats, pecans, apricots, peaches, nectarines, plums and prunes. On cereals it controls diseases
caused by Erysiphe graminis, Leptosphaeria nodorum, Pseudocerosporella herpotrichoides,
Puccinia spp., Pyrenophora teres, Rhynchosporium secalis, and Septoria spp.. Propiconazole's mode
of action is demethylation of C-14 during ergosterol biosynthesis, and leading to accumulation of
C-14 methyl sterols. The biosynthesis of these ergosterols is critical to the formation of cell walls
of fungi. This lack of normal sterol production slows or stops the growth of the fungus, effectively
preventing further infection and/or invasion of host tissues. Therefore, propiconazole is considered
to be fungistatic or growth inhibiting rather than fungicidal or killing.

ENVIRONMENTAL FATE
If released to air, a vapor pressure of 110-6 mm Hg at 25 indicates propiconazole will exist
in both the vapor and particulate phases in the atmosphere. Vapor-phase propiconazole will be
degraded in the atmosphere by reaction with photochemically- produced hydroxyl radicals; the
half-life for this reaction in air is estimated to be 5.5 hours. Particulate-phase propiconazole
will be removed from the atmosphere by wet or dry deposition. Propiconazole has been
reportated to be stable to photolysis. If released to soil, propiconazole has reported soil mobility
ranging from moderate to immobile depending on the organic carbon content of the soil. Propiconazole
is not expected to volatilize from dry soil surfaces based upon its vapor pressure. Volatilization from
water and moist soil surfaces is not expected to be an important fate process based upon an estimated
Henry's Law constant of 4.110-9 atm-cu m/mole.
Usage: Propiconazole was first developed in 1979 by Janssen Pharmaceuticals of Belgium.
It is used agriculturally as a systemic fungicide on turfgrasses grown for seed and aesthetic or
athletic value, wheat, mushrooms, corn, wild rice, peanuts, almonds, sorghum, oats, pecans,
apricots, peaches, nectarines, plums, prunes and lemons. It is also used in combination with
permethrin in formulations of wood preserver.
Application: Mode of Action Propiconazole is absorbed by the assimiliating parts of the plant,
the majority within one hour. It is transported upwards in the xylem. This systemic translocation
contributes to good distribution of the active ingredient within the plant tissue and prevents it
from being washed off. Uses Propiconazole can be used as systemic foliar fungicide with a
broad range of activity, at 100-150 g/ha. On cereals, it controls diseases caused by Cochliobolus
sativus, Erysiphe graminis, Leptosphaeria nodorum, Puccinia spp., Pyrenophora teres,
Pyrenophora tritici-repentis, Rhynchosporium secalis, and Septoria spp. In bananas, control of
Mycosphaerella musicola and Mycosphaerella fijiensis var. difformis. Other uses are in turf against
Sclerotinia homoeocarpa, Rhizoctonia solani, Puccinia spp. and Erysiphe graminis. In rice against
Rhizoctonia solani, Helminthosporium oryzae, and dirty panicle complex. In coffee against Hemileia
vastatrix. In peanuts against Cercospora spp. In stone fruit against Monilinia spp.,
Podosphaera spp., Sphaerotheca spp. and Tranzschelia spp. In maize against Helminthosporium spp.
