Storksbill is a low-growing, tap-rooted annual that thrives in low fertility pastures. It can cause problems in both new and established pastures, particularly in spring. Seedheads damage animal pelts.
Storksbill has also been recorded as causing staggers and photo-sensitisation in lambs and cattle.
More mature plants will only be suppressed. One well-timed spring application will also break the seed cycle and reduce the population in following seasons.
