GENERAL INSTRUCTIONS

SPECIAL WARNING – BANANAS

There are specific conditions when the surface of recently emerged fruit is particularly prone to marking damage from spray applications. In circumstances where the application will be made to very rapidly growing fruit in hot conditions with strong direct light, it is recommended that all emerged bunches be bagged prior to spraying to minimize the risk of fruit marking. Never include adjuvants other than water-miscible oils with APPARENT Whirlwind 430 SC Fungicide sprays. The inclusion of wetting agents is known to cause phytotoxicity to young fruit.

LETTUCE – To Avoid Crop Damage:

The sensitivity of some species and varieties of the crops to be treated has not been fully evaluated. It is advisable, therefore, to treat a small number of plants to ascertain their reaction before treating the whole crop.

FOLIAR DISEASES ON CEREAL CROPS

DO NOT apply to cereal crops more than once in a season. Treatment will give approximately three weeks of 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 7-10 days after application. Yield potential: crops with potential yield under 2t/ha are unlikely to give economic responses to a fungicide spray except under conditions of very severe disease. Economic responses are most likely with crops with a potential yield of over 3t/ha.

SPRAY TIMINGS FOR STRIPE RUST CONTROL

Obtain advisory literature from the Department of Agriculture for classification of resistant and susceptible varieties. In South Australia, consult Plant Protection Note PPN 21. In other states, the following spray program is suggested:

  • Seedling Infections: When approximately 20 out of 100 leaves show the first signs of infection during tillering to jointing, apply a spray within one week.
  • Adult Infections – Susceptible Varieties: When approximately 10 out of 100 leaves show the first sign of infection, apply a spray within one week. DO NOT delay.
  • Adult Infections – Moderately Susceptible Varieties: When approximately 15 to 20 leaves out of 100 leaves show the first sign of infection, apply a spray within one week. DO NOT delay.
  • Adult Infections – Moderately Resistant and Resistant Varieties: Monitor carefully. If rust appears and spreads, spray within one week.

RESISTANCE MANAGEMENT RECOMMENDATION – PEANUTS

Apply no more than 3 consecutive sprays of DMI fungicide (e.g., APPARENT Whirlwind 430 Fungicide) before switching to a non-DMI fungicide. Apply no more than 5 DMI sprays per season.

MIXING

Prior to pouring, shake the container vigorously, then add the required quantity of APPARENT Whirlwind 430 Fungicide to water in the spray vat while stirring or with agitators in motion. Add the required amount of Agridex† (peanuts, beans) or water-miscible oil (bananas) and mix thoroughly.

APPLICATION

Aircraft should fly as low as possible under the prevailing conditions to minimize drift.
