Introduction: Tebuconazole is a trazole fungicide. It is taken up by plants and transported within tissues. It is used as a seed dressing, which works effectively against various smut and bunt diseases of cereals. As foliar spray tebuconazole controls numerous phathogens such as rust species, powdery mildew, and scale in various crops. It is also used to control pests including yellow leaf spot, black spot, net blotch, and Scelerotinia rot. Tebuconazole can be applied to control above mentioned diseases on cereals (including wheat, barley, oat, rye), grapes, peanuts, vegetables (onions and peas), bananas, sugarcane.

If released to air, a vapor pressure of 1.28×10-8 mm Hg at 20 indicates tebuconazole will exist solely in the particulate phase in the atmosphere. Particulate-phase tebuconazole will be removed from the atmosphere by wet or dry deposition. Tebuconazole does not contain chromophores that absorb at wavelengths >290 nm and has been shown to be stable to photolysis from direct sunlight. If released to soil, tebuconazole is expected to have moderate to no mobility in soil and sediment based on measured Koc data ranging from 470-6,000. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 1.4×10-10 atm-cu m/mole. Tebuconazole is not expected to volatilize from dry soil surfaces based upon its vapor pressure. Biodegradation data were not available. If released into water, tebuconazole is expected to adsorb to suspended solids and sediment based upon the Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 140 suggests the potential for bioconcentration in aquatic organisms is high. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Tebuconazole has also been reported to be stable to hydrolysis in pure water.                      

Usage: Tebuconazole was introduced by Bayer. Tebuconazole is mainly used control of all kinds of fungi diseases on wheat, rice, peanuts, vegetables, bananas, apples, pears, corn, sorghum etc.

Application: Biochemistry: Steroid demethylation (ergosterol biosynthesis) inhibitor.

Mode of action: Systemic fungicide with protective, curative, and eradicant action. Rapidly absorbed into the vegetative parts of the plant, with translocation principally acropetally. Uses: As a seed dressing, tebuconazole is effective against various smut and bunt diseases of cereals such as Tilletia spp., Ustilago spp., and Urocystis spp., also against Septoria nodorum (seed-borne), at 1-3 g/dt seed; and Sphacelotheca reiliana in maize, at 7.5 g/dt seed.
