Carrot Root Fly Nematodes 60sq.m

Treat Root Fly in Carrots with Beneficial Nematodes

This soil-applied treatment helps reduce root damage caused by carrot fly larvae. One pack is suitable for up to 60 square metres of growing space.

Carrot Fly Lifecycle and Peak Risk Periods

Adult flies typically emerge between April and June, then again from late summer into autumn. After laying eggs near the base of plants, larvae hatch and start feeding on developing roots within a week.

Best Time to Apply the Carrot Root Fly Nematodes

Apply in spring to address the first wave, and again from late July to early October for the second. The microscopic organisms seek out and interrupt the larvae in the soil, helping to prevent ongoing issues.

Common Signs of Root Fly Damage

Larvae burrow into the roots of carrots, leaving reddish tunnels beneath the skin. You may also notice leaf wilting or a reddish hue in the foliage as symptoms develop.

How to Apply Nematodes to Soil

Mix the pack contents with water and apply using a watering can or applicator. If poured over foliage, rinse the plants within 30 minutes to ensure the product reaches the soil layer.

How to Store Before Use

Keep stored at a temperature below 5°C. Always use by the expiry date shown on the packaging for best results.

Improve Your Results with Physical Barriers

For increased protection, pair with Veggiemesh netting to limit adult flies from reaching the crop. This combined approach helps reduce long-term risk.
