GENERAL INSTRUCTIONS

Foliar Diseases on Wheat and Barley Crops

Treatment will give approximately three weeks disease suppression. Economic responses may not be gained by spraying crops past the flowering stage. The effects of fungicide application will not be clearly seen for at least 7-10 days after application.

Disease control in canola

Blackleg

Higher blackleg risk can be expected in higher rainfall districts (above 500 mm annual rainfall), where crops are grown within 500 m of a previous year’s stubble and in later sown crops (May to August). Other factors will also increase the risk of blackleg infection, including the intensity of canola cropping in a district, rainfall before sowing, and the frequency of growing the same canola cultivar. Consult industry guidelines for a more detailed assessment of blackleg risk in specific situations.

Sclerotinia

VERITAS OPTI is most effective when application is made prior to conditions conducive to sclerotinia infection. Infection and disease development are most conducive in warmer winter or spring conditions with extended periods of leaf wetness due to rainfall, dew, and high humidity. Sclerotinia is most likely to develop where day temperatures are warmer, coinciding with a saturated soil profile and rainfall events. Refer also to industry guidelines for advice on conditions under which sclerotinia are most likely to develop.

Control of sclerotinia stem rot is more effective in crops which have uniform flowering. Uneven flowering (e.g., caused by staggered germinations) makes optimum spray timing difficult and two sprays may be required in these crops. Generally, an application of VERITAS® OPTI at 20 to 30% flowering will control sclerotinia in crops with a short flowering interval. Crops with an extended flowering period may require a second application with an alternative registered sclerotinia fungicide up to 50% flowering (full bloom) to adequately control sclerotinia if conditions late in the season are conducive to the development of the disease.

Length of protection may be reduced in bulky crops where coverage is difficult and where there is growth dilution of the fungicide. For optimum protection, application should be directed to obtain coverage on petals, leaves, and stems.

MIXING

Prior to pouring, shake the container vigorously, then add the required quantity of VERITAS OPTI to water in the spray vat while stirring or with agitators in motion. Rinse the empty container with water and add rinsings to the spray tank.

APPLICATION

In each situation, use a spray volume to ensure good coverage for the canopy size and crop growth stage. Where a spray volume range is recommended, use the higher volume in the range to improve coverage and efficacy, particularly at later growth stages and with dense crop canopies.

• Ground Application: Barley, canola, pulses, and wheat: Apply product using a spray volume of 70 to 100 L/ha and a MEDIUM spray quality. Peanuts: Apply in spray volumes ranging from 100 to 500 L/ha. Use of hollow cone or flat fan nozzles is recommended.

• Aerial Application: Aircraft should fly as low as possible under the prevailing conditions to minimize drift. Aerial application MUST BE carried out with closed mixing/loading. Barley, canola, pulses, and wheat: Apply product using a minimum spray volume of 20 L/ha and a MEDIUM spray quality. Peanuts: Apply a minimum of 30 L/ha spray volume. Use a higher spray volume of 60 L/ha when applying to dense crops.

Resistance Warning: FUNGICIDE RESISTANCE WARNING

VERITAS OPTI is a member of the DMI and Quinone outside Inhibitors (Qols) group of fungicides. For fungicide resistance management, the product is both a Group 3 and a Group 11 fungicide. Some naturally occurring individual fungi resistant to VERITAS OPTI and other Group 3 and/or Group 11 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungal population if these fungicides are used repeatedly. These resistant fungi will not be controlled by this product and other Group 3 and/or Group 11 fungicides, thus resulting in a reduction in efficacy and possible yield loss. Since the occurrence of resistant fungi is difficult to detect prior to use, ADAMA Australia Pty. Ltd. accepts no liability for any losses that may result from the failure of VERITAS® OPTI to control resistant fungi. Refer to the Croplife Australia website for current resistance management guidelines prior to the use of VERITAS® OPTI.

Precautions: Re-entry period

Do not allow entry into treated areas until the spray has dried unless wearing cotton overalls buttoned to the neck and wrist (or equivalent clothing) and chemical-resistant gloves. Clothing must be laundered after each day’s use.

Protections: WARNING

• VERITAS OPTI is extremely phytotoxic to certain apple varieties. Extreme care must be used to prevent injury to apple trees.

• AVOID SPRAY DRIFT. DO NOT spray VERITAS OPTI where spray drift may reach apple trees.

• DO NOT use spray equipment to spray apple trees that have been previously used to apply VERITAS OPTI. Even trace amounts can cause unacceptable phytotoxicity.

• DO NOT spray when conditions favor drift beyond the area intended for application. Conditions that may contribute to drift include thermal inversions, excessive wind speed, certain sprayer nozzle/pressure combinations, small spray droplet size, etc.

PROTECTION OF WILDLIFE, FISH, CRUSTACEANS, AND ENVIRONMENT

Very toxic to aquatic life. DO NOT contaminate streams, rivers, or watercourses with the chemical or used containers.
