SUPRAKAL

Mode of action

• Curative effect: an alkaline reaction from its high pH (about 11.2).
• It saponifies the lipids of the cell wall, so it passes through the wall more easily.
• Preventive effect: it interferes with the citric acid cycle of the fungus.

Properties and benefits

• Strong curative effect during the primary ascospore period of scab.
• Curative effect against peach leaf curl (Taphrina deformans), plum rust (Tranzschelia pruni), cherry leaf spot (Blumeriella jaapii) and shot hole disease (Coryneum).
• Comparable to chemical curative plant protection products, and can replace a chemical curative product that no longer works because of resistance.
• No risk of resistance, because its mode of action is not specific.
• Leaves no residue.
• Helps prevent resistance when used in programs with conventional fungicides.
• Good side effect on Marssonina, sooty blotch and powdery mildew.
• Good side effect on mites.

Time of application

Citrus red spider mite: In citrus orchards in spring, from late February to early March, count the moving mites on the upper and lower leaf surfaces with a magnifying glass. If there are more than 4 to 9 live mites on ten leaves, spray. Spraying can also be done a week after fruit set.

Root-knot nematode in tomato: Applied with soil solarization. Wet the soil thoroughly, then cover the surface with clear plastic so the gas cannot escape. Apply SUPRAKAL through the drip irrigation system to a depth of 20-25 cm, with no more than 5% SUPRAKAL in the prepared solution. Keep the solarization for at least 2 to 4 weeks.

Spiral nematode in banana: Spray first when the plant has 3 to 4 leaves above ground, again when the first bunch forms, and a third time when the fruit clusters form. Repeat each application 3 times, 10 days apart.

Broad mite in greenhouse vegetables: Pick 30 plants at random across the greenhouse and take one leaf from the upper part and one from the middle of each. Spray when counts show 4 to 5 live mites per leaf.

Powdery mildew: If the disease appears in the orchard for the first time, start spraying as soon as symptoms show. If it was seen in previous years, start at fruit set. Repeat until harvest, according to how severe the disease is, the weather and how long the product stays effective.

Big bud mite in hazelnut: Between April and May, when shoots have 4 to 4.5 leaves, new buds are half the size of a pinhead and young nuts are the size of a lentil (about 3 mm across), spray at the end of April or early May if there are on average 5 infested buds per branch.

Powdery mildew in tomato, field and greenhouse: Spray when the first signs of the disease appear, in the field or the greenhouse. Repeat according to how severe the disease is, the weather and how long the product stays effective.
