Impact

Impact

Datura stramonium is one of the world's most widespread weeds and has been recorded from over 100 countries. It is a poisonous weed that competes aggressively with crops in the field and pasture. All parts of Datura plants contain dangerous levels of poison and may be fatal if ingested by humans and other animals, including livestock and pets. D. stramonium has been listed as a noxious weed in South Africa  and several Australian states(prohibited plants that must be controlled). They serve no economic purpose and possess characteristics that are harmful to humans, animals or the environment)  In some countries of the world, it is also prohibited to buy, sell or cultivate Datura plants., Thorn apple (recurved) competes strongly with summer species for moisture and nutrients. Although it displaces annual grasses, ground cover and riparian vegetation, it is not known to be a serious weed of natural ecosystems., Dense infestations occur in pastures and on river flats, producing a complete ground cover. The plants die in the cooler autumn weather. However, dead plants bear capsules that may remain standing through winter into spring., Seeds of D. stramonium are long lived, 91% surviving 39 years burial at 34 cm in one experiment
