Description

Cover Crop PreSpud Mix

Cover Crop PreSpud Mix combines 80% Brown Mustard with 20% Tillage Radish and is grown specifically as a biofumigation crop ahead of potatoes.

When flailed and incorporated at flowering, the brown mustard releases glucosinolates into the soil which break down into naturally occurring biofumigant compounds, helping to suppress nematode populations that would otherwise trouble a potato crop.

The tillage radish contributes its own deep, fast-growing taproot, which relieves compaction and leaves well-structured channels behind as it decomposes.

Together the pair produce a lot of biomass in a short space of time, making this a popular choice for growers rotating ground into potatoes the following season. Sow from spring through to early autumn.

Common Questions

How does Cover Crop PreSpud Mix help with potato cyst nematode? The brown mustard component releases glucosinolate compounds when it's chopped and incorporated at flowering, which act as a natural biofumigant in the soil and can help suppress nematode numbers ahead of a susceptible crop like potatoes.

When should I flail and dig in PreSpud Mix? For the best biofumigation effect, flail the crop just as the mustard comes into flower, then incorporate into the soil straight away while the plant material is still fresh.

What sowing rate should I use for PreSpud Mix? Sow at 1 gram per square metre (4kg per acre), which is a much lighter rate than most cover crop blends thanks to the fine seed size of mustard and radish.
