36734-19-7 Propiconazole Fungicide Chemical Pesticide for Seed , Corn , Peanuts , Oats

Description:

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.
