Leaf Miner

DIGLYcontrol (Diglyphus isaea) – Fast-Acting Leaf Miner Control for Protected Crops

Leaf miners can wreak havoc on young plants – cutting through leaf tissue, reducing growth, and leaving unsightly trails that knock saleability and performance. DIGLYcontrol offers a precise, natural way to shut them down early, without relying on chemical sprays.

Inside each bottle is Diglyphus isaea, a tiny parasitic wasp that moves fast. Unlike other species that lay inside the larvae, Diglyphus paralyses the leaf miner and lays its egg beside it. The developing wasp larva then feeds externally – finishing the pest off in the process. It’s a quick, effective route to control, and one that slots easily into any biological programme.

Once released, these wasps immediately search for activity in the leaf. They work best when leaf miners are already present in low numbers – making them ideal for curative use or where outbreaks are spotted early.

Some growers alternate or combine Diglyphus with Dacnusa sibirica for more layered control – especially where multiple miner species are present.

Best for use in:

• Ornamentals and greenhouse crops suffering from active leaf miner infestations
• Systems where visible leaf damage affects salability or market access
• Growers needing fast, chemical-free relief from minor outbreaks
• Use alongside yellow sticky traps to monitor presence and reduce adults

How to apply:

Use at a guide rate of 0.5 wasps per square metre. Apply during active leaf miner presence, ideally in warm, still conditions. Avoid applying broad-spectrum pesticides before or after release.

Delivery note:

This is a live, temperature-sensitive product. To ensure best viability, place orders before 5pm Wednesday for delivery the following week.

DACNUcontrol (Dacnusa sibirica) – Natural Leaf Miner Control for Protected Crops

Leaf miners can catch you off guard – leaving pale trails in the foliage, weakening young plants, and causing cosmetic damage that’s hard to reverse. DACNUcontrol gives growers a clean, reliable way to fight back, without reaching for the spray lance.

What’s inside the bottle? A tiny but tough little wasp called Dacnusa sibirica. It’s nature’s answer to leaf miner infestations. Instead of chasing pests with chemicals, Dacnusa quietly patrols the crop, finding leaf miner larvae and laying its eggs right inside them. The larvae don’t make it much further after that.

As soon as they’re released, these wasps get straight to work – settling into the crop and blending into the canopy like they’ve always belonged there. They’re especially handy in greenhouses, propagation tunnels, or anywhere sprays don’t quite cut it. The trick is timing: you’ll get the best results by introducing them early, before the miners get deep into the leaf or start to pupate.

They work well on their own, but many growers team them with Diglyphus isaea or sticky traps for broader, more sustained control.

Best used for:

• Ornamental or edible crops where leaf miner damage needs fast response
• Protected systems where foliage appearance or vigour is critical
• Growers aiming to reduce insecticide use in tight or sensitive crops
• Sites using preventative or early-stage IPM programmes

How to apply:

Use at roughly 0.25 - 0.5 wasps per square metre. Apply preventatively or at the very first sign of leaf miner activity. Avoid spraying broad-spectrum insecticides before or just after release, and use sticky traps to monitor how well they’re establishing.
