Jagung, sorgum, dan tebu adalah tanaman yang paling sering terganggu oleh striga, bahkan dapat menimbulkan kerugian 100%, termasuk di [[Amerika Serikat]]. Di Afrika, striga menjadi salah satu pengganggu terpenting. Sekitar 40% lahan savanna Afrika yang dapat digarap terkena dampak striga, sehingga menyebabkan kerugian sampai 13

Maize, sorghum, and sugarcane crops affected by witchweed in the United States have an estimated value well over $20 billion.<ref name="Sand" /> Furthermore, witchweed is capable of wiping out an entire crop.<ref name="Wales" /> In fact, it is so prolific that in 1957 Congress allocated money in an attempt to eradicate witchweed. Thus, the Animal and Plant Health Inspection Service ([[APHIS]]) of the U.S. Department of Agriculture established a research station and control methods.<ref name="Pest" /> Through infestation mapping, quarantine, and control activities such as contaminated seed destruction, the acreage parasitized by witchweed has been reduced 99% since its discovery in the United States.<ref name="Pest" /> APHIS has even offered cash rewards for those identify and report the weed, and encourages landowners to check their own acreage.<ref name="Pest" />

* ''Striga asiatica'' has a very wide geographic distribution, from Africa through southern and eastern Asia to Australia. Since the 1950s, it is also known from the United States. This introduction, likely a result of human activity, resulted in an infestation of corn ([[maize]]) across many counties in North and South Carolina. The United States Department of Agriculture and state agencies imposed a quarantine on this area to control its spread - a process that was apparently successful.
* ''[[Striga gesnerioides]]'', cowpea witchweed, as its name implies, is a parasite of [[cowpea]] (''[[Vigna unguiculata]]''), which is not a grass, but a member of the legume family ([[Fabaceae]] or [[Leguminosae]]). This species was also accidentally introduced into Florida in the United States, where it was found parasitizing ''[[Indigofera]]'' ''hirsuta'' (hairy indigo, another legume).
