Plants showing symptoms early in the growing season may grow out of the problem as chemical residues break down. Harvestable produce from plants exhibiting symptoms is considered safe to eat. Vegetables such as courgettes, brassicas and salads are unlikely to show any distorted growth. A number of cases in 2016 suggest some sources of growing media (e.g. growbags) may be contaminated with hormonal weedkiller, most likely from composted green waste containing clopyralid. See section below on how to run a germination test if you suspect a compost may be a source of weedkiller residues. Glyphosate
