Climatic ConditionsA. fatua is a cosmopolitan grass weed growing on nearly all soil types. The plant tolerates soil pH as low as 4.5 (Holm et al., 1977), but calciphilous subspecies are also found (Korniak, 1985; Hanf, 1990). Growth and viability are not restricted by low temperatures, although A. fatua has its origin in the relatively arid climate of Asia.
Life CycleNot set
Dispersal MechanismA. fatua has relatively large seeds, the majority of which fall close to the parent plant. There are no reports of natural dispersal by wind or water, though this must occur to some extent. Movement by animals is similarly not discussed in the literature. The dispersal and spread of A. fatua is closely associated with the cultivation of cereal crops around the world. Movement over longer distances is most likely the result of importation of contaminated grain.

#CommodityPlant Parts AffectedControl MeasuresEconomic Importance
1 Maize Seeds Clean seed/grain A. fatua has been used to develop resistant traits in wheat (Tang et al., 1997). Resistance of a tetrageneic hybrid of triticum, Avena and Elymus conferred resistance in wheat to leaf rust (Puccinia recondita), stems rust (P.graminis) stripe rust (P. striiformis), powdery mildew (Erysiphe graminis) and root rot (Alternaria alternata). It is also utilized as an animal fodder/forage and a source of drought resistance genes. The weed is also a major host of Pseudomonas syringae pv. coronafaciens (halo blight); Pseudonapomyza atratula and a minor host of Cochliobolus sativus (root and foot rot); Pratylenchus penetrans (nematode, northern root lesion).
