How can a weed become a witch?




In worldwide cultures, religious and mythologies, a witch denotes someone who possesses certain kinds of supernatural or magical powers in order to inflict harm or damage upon people. This qualification was applied to a wide spread parasitic weed: Striga hermonthica and the question remains “how a weed can become a witch”? In general a weed is any plant that is considered by the user of the term to be harmful, a nuisance (to crop) and unwanted where it occurs; and a parasitic weed is a weed that requires the presence of the host: (crop) for its development. S. hermonthica germinates only in the presence of the host and establishes as soon as it germinates a connection between the host’s roots and take water and nutrients from the host plant. The fact that S. hermonthica possesses a high proliferation, causes most of its damages in the soil (40-100% of yield losses) before appearing above the soil and, till now no control method has been discovered; thus this makes the weed to be considered as possessing a supernatural or magical power, so called witchweed. For any scientist going to deal with S. hermonthica, the main question he needs to answer is “Can you kill a witch”?

  1. In worldwide cultures, religious [religions] and mythologies, a witch denotes someone who possesses certain kinds of supernatural or magical powers in order [drop: in order] to inflict harm or damage upon people. This qualification was applied to a wide spread parasitic weed: Striga hermonthica and the question remains “how a weed can become a witch [how can a weed become a witch: place of 'can']”? In general [add a comma] a weed is any plant that is considered by the user of the term to be harmful, a nuisance (to crop [or: crops]) and unwanted where it occurs; and a parasitic weed is a weed that requires the presence of the [of a host] host: (crop) for its development. S. hermonthica germinates only in the presence of the host and establishes as soon as it germinates [put the time indication at the end of this phrase; not in between the verb and the object of the sentence]a connection between the host’s roots [the roots of the host/only use genititves for persons/time/places]and take water and nutrients from the host plant. The fact that S. hermonthica possesses a [possesses high proliferation; uncountable noun] high proliferation, causes most of its damages [damage used as an uncountable noun here]in the soil (40-100% of yield losses) before appearing above the soil and, till now no control method has been discovered; thus this makes the weed to be considered as possessing a supernatural or magical power, so called witchweed [sentence is too difficult due to the many subclauses, which hampers flow]. For any scientist going to deal with S. hermonthica, the main question he needs to answer is “Can you kill a witch”? [nice way of linking back to the start]
