Product Description:

Oxycarboxin is a highly effective systemic fungicide belonging to the carboxin chemical family, known for its broad-spectrum activity against soilborne and foliar fungal pathogens. It is primarily used for the control of diseases caused by Basidiomycetes and Ascomycetes fungi, including important diseases such as root rot, smuts, and rusts.

Its unique mode of action inhibits fungal mitochondrial respiration by blocking the succinate dehydrogenase enzyme (complex II in the electron transport chain), thereby disrupting energy production within fungal cells. This action results in the suppression of fungal growth and development.

Oxycarboxin is widely used in cereals (especially wheat and barley), soybeans, and turfgrass management, offering excellent protection for seedlings and established plants. Its systemic and protective properties allow it to prevent infection and inhibit the development of existing fungal colonies.

Key Features & Benefits:

• ✅ Systemic action with translocation in plant tissues ensures thorough disease control

• ✅ Broad-spectrum efficacy against soilborne and foliar diseases such as smuts, rusts, and seedling root rots

• ✅ Protective and curative properties for enhanced disease management

• ✅ Long residual activity reduces frequency of application

• ✅ Highly effective in seed treatment and foliar application

• ✅ Improves seedling vigor and crop establishment

• ✅ Compatible with many other fungicides and pesticides for tank mixing

• ✅ Low phytotoxicity and safe for crops when used according to guidelines

Target Crops:

• Wheat

• Barley

• Soybeans

• Turfgrass and lawn grasses

• Other cereals susceptible to rust and seedling diseases

Target Diseases:

• Seedling blight and root rot caused by Rhizoctonia solani and Fusarium spp.

• Loose and covered smuts of cereals (Ustilago spp., Tilletia spp.)

• Rust diseases (Puccinia spp.)

• Other Basidiomycete-related diseases

Mode of Action:

Oxycarboxin acts as a succinate dehydrogenase inhibitor (SDHI), interfering with the fungal mitochondrial respiratory chain (complex II), halting ATP production, and effectively starving fungal cells of energy. This selective mode of action provides strong fungicidal effects with minimal impact on non-target organisms.

Application Guidelines:

• Application Methods: Seed treatment, soil treatment, foliar spray

• Seed Treatment:

  • Apply recommended doses to seeds prior to planting for protection against soilborne pathogens and early seedling diseases

• Foliar Application:

  • Use for controlling foliar diseases such as rusts on cereals

  • Typical dose ranges from 200 to 400 g/ha depending on crop and disease pressure

• Timing:

  • Seed treatment before sowing

  • Foliar sprays applied preventively or at early disease symptoms

• Follow label-specific recommendations for frequency and dosage

Formulations & Packaging:

• Formulations:

  • 75% WP (Wettable Powder)

  • 50% SC (Suspension Concentrate)

• Packaging:

  • 100 g, 250 g, 500 g, 1 kg packs for small scale use

  • Bulk packaging available for commercial growers

Storage & Handling:

• Store in a cool, dry place away from direct sunlight and moisture

• 2 to 3 years when stored properly in original packaging under recommended conditions

Environmental and Safety Considerations:

• Low toxicity to mammals when used as directed

• Should be used responsibly to avoid environmental contamination

• Follow all local regulatory guidelines for application rates and safety precautions

Conclusion:

Oxycarboxin is a reliable and effective systemic fungicide widely used for protecting cereals and soybeans against serious fungal diseases, particularly smuts, rusts, and seedling root rots. Its unique mode of action and systemic movement provide excellent preventive and curative control, enhancing crop health, vigor, and yields.
