Ampelomyces quisqualis is an indigenous fungal isolate to South Africa, and a hyper parasite to the common Powdery Mildew.
Direction for use:
5g per litre dechlorinated water
As this leaves a residue of diatomaceous earth on the leaf surface it is best used in vegetative stage for cannabis plants. The liquid AQ sf is best for flower
400 g AQ-SF / 1 ha
Wash spray tank thoroughly to remove all traces of chemicals and fill with water (pH 6.0 – 7.3). Half fill a 10 liter bucket with water (pH 6.0 – 7.3) and empty sachets into water while stirring. The carrier medium (diatomaceous earth) may block nozzles and should therefore stay behind while emptying bucket into spray tank. Repeat at least three times. Add a light mineral oil (0.3% of tank mix). Wet plants thoroughly. Apply early morning or late afternoon. Do not spray if air temperature rises above 30o C or when the relative humidity is lower than 30%. High humidity is conductive to the effectivity of the fungus.
If spilled on skin, rinse with water. Keep out of reach of children and uninformed persons.
