How to use BlackJak

Potatoes

Perform the first treatment when plants reach 20–25 cm, repeat the next treatment after 2–3 weeks. Dose: 2 l/ha

Seed potatoes

Use from 100 to 200 ml/1 l of water per 100 kg of seed potatoes, can be used together with chemical dressings

Carrot, parsley

Perform the first treatment when the foliage reaches 10–15 cm, repeat the second treatment after 2–3 weeks. Dose: 1 l/ha

Vegetables from seedlings

Soak or water the seedlings before planting using 250 ml per seedlings intended for an area of 1 ha (recommended amount of water: approx. 100 litres).

About 14 days after planting seedlings in the field, apply a dose of 2 l/ha /300–500 litres of water.

In case of use through the irrigation system, dose 250 ml/100 litres of water, the treatment can be repeated after approx. 14 days.

Orchards

New plantings: soak tree roots before planting, using a dose of 250 ml/100 litres of water.

After the onset of vegetation, apply fertigation 300–500 ml/1000 l of water.

Apply foliar together with fertilisers and plant protection products at a dose of 50 ml/100 litres of water.

At optimal temperatures (>18°C), used together with gibberellins, it allows reducing their dose by 15-20%. At lower temperatures (14-18°C) it improves transport and effectiveness of gibberellins. 

Strawberries

New plantings: soak seedlings before planting, using 250 ml/100 litres of water.

2 weeks after planting, apply a dose of 2 l/ha.

In the second or third year of cultivation: perform the treatment after the onset of vegetation with a dose of 2 l/ha, repeat after approx. 15 days

Accelerating emergence

Small seeds: water immediately after sowing using 250 ml/100 litres of water.

Drip irrigation (Fertigation):

Immediately after planting 300–500ml/1000 litres of water, repeat treatment every 3–4 weeks.

Addition to foliar fertilisers (better fertiliser utilisation): 50 ml/100 litres of water.

Buffering spray liquid to lower pH: 50 ml/100 litres of water
