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.
