|Description||Annual, unpleasant-smelling, seed-propagated weed.|
Very big leaves, coarse-dentated, not mealy covered.
Long oval, petiolate.
Hairless, sometimes farinaceous, with spread-apart ramifications in the upper part, up to 100 cm tall.
Large up to 20 cm (7.87 inch), cordate at the base, triangular, coarsely toothed or lobed, acuminate.
Glomerules in paniculiform inflorescence, leafless at the top.
End of spring - early autumn.
Dull black, lens-shaped, 1.5 mm (0.059 inch) or more in diameter, and covered with thin tissue that rubs off. Germination in spring.
Viability of Seeds
Seeds persist more than 10 years in the soil.
By seeds. Seeds per plant: 1,000-15,000.
Fence rows and waste areas, row crops, ways, gardens.
Primarily on nitrogen-rich, friable soils in warm regions.
Ch. hybridum causes high yield losses due to strong competition for light, nutrients and water. Compared with Chenopodium album it prefers higher temperatures.
Useful non-chemical contribution to Integrated Weed Management
Because of its persistence in the seed bank it is important to prevent seed rain.
