Bugs & Beasts
Everything likes to eat sunflowers from the moment they are planted, especially slugs. Hares, rabbits and birds will also eat the growing shoots.
Only pre-emergence chemical currently available.
Botrytis can occur in the seed head, but this will only cause the seed to shed which is a benefit in game cover crops. At early stages of growth this crop will produce toxins. Therefore rabbits and deer will tend to leave it alone, but ensure it is fenced from any domestic livestock.
