Using Serenade Optimum on 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.

Using Serenade Optimum on 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.

Using Serenade Optimum on 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.

Using Serenade Optimum on 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.

Using Serenade Optimum on 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.

Using Serenade Max on 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.

Using Serenade Optimum on 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.

Using Serenade Optimum on 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.

Using Serenade Optimum on 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.
