| Fallopia convolvulus |
Fallopia convolvulus is another weed that has a restricted germination 'window' and only occurs in spring-sown crops. It can form very large clumps in open crops such as potatoes but is less aggressive in spring cereals. Like other members of the Polygonaceae it is known to be an important food source for birds, both chicks and adults.
