Aptus - Fungone Concentraat 1:4

The same formula as ready-to-use Fungone, concentrated at 1:4. One part product to four parts water, so a litre of concentrate yields five litres of spray. For anyone with more than one tent to cover, that is the whole difference.

The arithmetic

One to four means: 200 millilitres of concentrate plus 800 millilitres of water gives one litre of ready spray. To make five litres, that is a full litre of concentrate to four litres of water.

Mix in that order and measure with a jug rather than by eye. At 1:4 the margin is small: overestimate and you spray unnecessarily strong over your crop, underestimate and the layer is too thin to do anything.

Mix what you will use today

Hydrogen peroxide is unstable, which is exactly why it works. Mixed solution therefore starts losing strength immediately, faster still in light and warmth. A remainder standing in the sprayer for a week is not weaker Fungone, it is water.

So work out in advance how much area you are covering and mix that volume. With this product that is not thrift, it is how you make sure the second half of your crop gets the same treatment as the first.

Spraying is unchanged

Use the mixed solution exactly as the ready-to-use version: mist evenly to a uniform layer, and only under dimmed light or at the start of the dark period. Wet leaf under a running lamp burns, and light breaks the product down before it does its job.

Frequently asked questions

How much water to how much concentrate? Four parts water to one part concentrate. For a litre of spray: 200 millilitres of product and 800 millilitres of water.

Can I mix a stock in advance? Better not. Hydrogen peroxide breaks down, so mixed solution loses strength. Mix what you will use that day.

Is this stronger than the ready-to-use version? Once diluted it is the same product. The difference is what you buy and carry, not what lands on your leaf.

When should I choose the concentrate? As soon as you regularly need several litres at a time. For a single tent the ready-to-use bottle is simpler.
