Field bindweed is a perennial climbing weed that is extremely problematic in agriculture and especially cereal and corn crops. It has been known to harbour tobacco mosaic virus, therefore, it is necessary to make sure no infestation occurs anywhere near potatoes, tomatoes etc. Key identifying features of this climbing weed relate to its ability to grow rather long (100 cm) and its flowers resembling the morning glory flower. Roots can grow to a depth of 4 meters and store a 2 year supply of food, so control can be an effort over more than one season.
The cotyledon can range from 8-20 mm and are a dull green. They have distinct white veins and are square in shape. The mature plant resembles the cotyledon.
Ranges from 20-100 cm in height and the stems will grow along the ground (prostrate) or grow over and around crops. Flowers are white to pink in colour and are shaped like funnels or a trumpet (similar to a morning glory). Their bloom occurs in May and the flowers will close and open each day. Field bindweed spreads through seed and rhizomes (roots).
Optimal growth conditions
This perennial weed can grow in a wide variety of conditions, from loam to clay, and sandy soils were it is most common. It can survive dry soil but is less tolerant to high salinity.
