Walnuts Pest & Disease Programs — Biological Inputs That Fit Your Spray Window
Natural program for walnut orchards — codling moth and husk-feeding larvae, the fungal blight and anthracnose complex, mites in the summer canopy, and nematodes in the root zone.
Growing walnuts with Vegalab
Codling moth drives the walnut spray calendar, with husk-feeding caterpillars and larvae following through hull split. Alongside it sit anthracnose and the blight complex in wet springs, spider mites colonising the canopy through hot summers, and lesion and ring nematodes working on the root system in sandier ground.
Vegalab's Larva Control targets codling moth and the husk-feeding larvae, Spore Control covers anthracnose and the fungal blight complex, and Spider Mite Control delivers knockdown in the summer canopy. Nematode Control is applied to the root zone against lesion and ring nematodes. Because every one of these carries zero pre-harvest interval and zero re-entry, applications can run right through hull split and up to harvest without a timing penalty — which matters most in exactly the window when walnut quality is decided.

Frequently asked questions
What controls codling moth in walnuts naturally?
Larva Control is a plant-extracted broad-spectrum larvicide applied foliar against codling moth and husk-feeding larvae, with zero pre-harvest interval and zero re-entry so it can be used close to harvest.
Does Vegalab help with walnut anthracnose?
Yes — Spore Control is a thyme-oil fungicide applied preventatively against anthracnose and the fungal blight complex ahead of favourable weather.
Are nematodes a problem in walnut orchards?
Lesion and ring nematodes reduce vigour and long-term productivity, particularly in sandy soils. Nematode Control is applied to the root zone to reduce populations; it carries 0 PHI / 0 REI.
