Serenade Optimum

Serenade Optimum is a bio-fungicide/bactericide to aid in the control and suppression of powdery mildew and botrytis and sour rot in grapes, fireblight in pipfruit, botrytis on berryfruit, kiwifruit, persimmons and onions, and various diseases on avocados, citrus, lettuce and turf. Serenade Optimum is a new improved formulation to replace Serenade Max.

Serenade Optimum is a higher concentrated (2 x strength) formulation that is easier to use.

Application Rate/Timing	Apples & Pears Disease: Fireblight Make the first application up to 5% blossom and apply 125 - 250 g/100 L (or 1.25 - 2.5 kg/ha) following a streptomycin application to minimise disease resistance to antibiotics. Under severe disease infection periods, repeat applications may be made at 3 - 7 day intervals, using the longer interval after petal fall. The addition of a suitable adjuvant (eg Du-Wett) is recommended. For more information on using Serenade Optimum in apples and pears go to "Use in Apples for Fireblight" in the downloads section Avocados Disease: Anthracnose Apply 100 g/100 L in a tank mixture with the lowest rate of a copper-based fungicide, or 150 g/100 L alone over flowering. Citrus Disease: Botrytis Use 1.25 - 2.0 kg/ha or 125 - 200 g/100 L in sufficient water to ensure complete coverage of plants and flower parts. Apply at 50% flowering and repeat at 7 - 10 day intervals if disease conditions persist. Ensure high volume application with surfactant for coverage. Disease: Anthracnose Apply 1.25 - 2.0 kg/ha or 125 - 200 g/100 L to ensure complete coverage of plants and flower parts at monthly intervals from early flowering to harvest. Disease: Greasy spot Use 1.25 - 2.0 kg/ha or 125 - 200 g/100 L to ensure complete coverage. For suppression, begin applications at first leafy flush, and repeat at later flushes. Include spray oil in tank mixture. Can also be tank mixed with other fungicides including copper-based ones. Disease: Melanose Use 1.25 - 2.0 kg/ha or 125 - 200 g/100 L in sufficient water from to ensure complete coverage of plants and flower parts from petal fall and repeat at 14 - 21 day intervals. Grapes Disease: Grey mould, Powdery mildew, Sour rot Use 1.25 - 2.0 kg/ha or 125 - 200 g/100 L in sufficient water to ensure complete coverage of plants and flower parts. Serenade Optimum can be used all season particularly in organic crops. Use no more than two applications back to back without alternating with other products. Under high pressure in conventional blocks use the best available alternatives at critical timings 80% cap fall and bunch closure. Serenade Optimum can be used later in the season as it has nil residues and no withholding period restrictions. Two strategically timed applications of Serenade Optimum are recommended at 4 - 5 weeks from harvest and again one week from harvest. For more information on using Serenade Optimum in grapes go to the FAQ document in the downloads Kiwifruit Disease: Botrytis Use 1.25 - 2.0 kg/ha or 125 - 200 g/100 L when disease conditions are conducive to infection at late flowering to early fruit set and immediately pre-harvest. Under heavy disease pressure, use in a spray program with other fungicides. May give suppression of sclerotinia. Lettuce Disease: Sclerotinia minor Use 1.25 - 2.0 kg/ha or 125 - 200 g/100 L. Apply as a soil drench immediately before or after transplanting or seedling crop emergence. Repeat as necessary before crop coverage of the soil and alternate with another fungicide for greater disease control spectrum. Does not control sclerotiorum. Ornamentals Diseases: Botrytis & Downy mildew Apply 1.25 - 2.0 kg/ha or 125 - 200 g/100 L in sufficient water to ensure complete coverage of plants and flower parts at the first sign of disease and repeat at 7 - 10 day intervals. Persimmon Disease: Botrytis Use 1.25 - 2.0 kg/ha or 125 - 200 g/100 L. Apply over flowering and repeat at 7 - 10 day intervals if disease conditions persist. Strawberries and Berry Fruit Disease: Botrytis Use 1.25 - 2.0 kg/ha or 125 - 200 g/100 L in sufficient water to ensure complete coverage of plants from early flowering and during harvest at 10 - 14 day intervals if disease conditions persist. Include a wetting agent and repeat in a program of alternation with other fungicides. Onions Diseases: Botrytis & Downy mildew Use 1.25 - 2.0 kg/ha or 125 - 200 g/100 L in sufficient water to ensure complete coverage of plants and flower parts. As part of a program, apply pre-harvest for the moderate control and suppression of diseases.
Compatibility	Do NOT combine Serenade Optimum in the spray tank with pesticides, surfactants, copper-based products or fertilisers unless prior experience has shown the combination to be compatible. Any tank combinations must also be tested for effectiveness on disease and selectivity to plants before use on commercial areas. If the use of any tank mixture is desirable, a small volume of the mixcture should first be tested in a small measured volume, for physical compatibility at the dilution rates required. If this test is positive, a field test of the mixture should then be carried out on a few plants to observe effectiveness and plant safety.
