Maher Propiconazole (25% EC)
The mechanism of action:
Propiconazole is a foliar systemic fungicide and prevents steroids from dimethylation. It has a protective and therapeutic effect, and this fungicide is absorbed by plant tissues and systemically distributed in the plant, it has the property of displacement in the plant and is displaced from leaf to root and vice versa through a xylem. Of course, the systemic motion in the plant is more upward, from the root to the leaf, or from the lower leaves to the higher leaves, although movement to downwards is as well as done. 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. The plant metabolizes propiconazole by hydroxylation of the n-propyl group to beta-hydroxy isomers. Propiconazole appears to have no harmful effects on the soil microbial agents and its movement in the soil is limited. It is washed in acid soils and mineral materials in the range of 5 to 7.5 centimeters in the soil surface. In the soils with fewer minerals, it can penetrate a depth of 20 to 25 cm.
Indications:
This fungicide is used against a wide range of fungal diseases such as Indian smuts, cereal black rust, crown and root rot, fusarium and septoria diseases of wheat, rice sheath blight, sugarcane smut, and on weeds for corn, wild rice, peanut, almond, sorghum, oats, central America walnut, banana, apricot, peaches, nectarine, tomatoes, plums and ornamental plants. It controls the diseases caused by Erysiphe graminis, Leptosphaeria nodorum, Puccinia spp., Septoria spp. on cereals. The interval between the last spraying and harvesting of rice, wheat and barley is 30 days and corn is 21 days.
