Parasitic weeds of arable land
1982This chapter deals with parasitic weeds of arable land, that is, weeds that depend upon host plants for food and or water obtained thrugh absorptive organs termed haustoria. The parasitic habit is widespread among angiosperms and at least five different orders have parasitic genera.

Protection of crops against parasitic weeds
Crop Protection, 1991Abstract Parasitic plants have been the subject of intensive study over the past 20 years and there has been considerable progress in understanding their physiology and biochemistry. Progress in control methods, the main subject of this review, has been less impressive and problems from the agriculturally important parasitic weeds, especially the ...

Parasitic Weeds and their Management
Parasitic flowering plants deprive the host plants of water, nutrients, and assimilates. Data also suggests that parasites transmit inhibitory compounds to hosts. Several species of the genera Striga and Orobanche (root parasites), as well as some species of Cuscuta and Loranthus (stem parasites), are widely distributed worldwide and cause substantial ...Rakesh Kumar, Pardeep Kaur, null Robin

Witchweed: a Parasitic Weed of Grain Crops
Outlook on Agriculture, 1990The witchweeds, in the genus Striga, are a remarkable group of obligate flowering plant parasites, some of which attack and destroy the crops of small-scale farmers in many parts of the semi-arid tropics. Striga hermonthica devastates sorghum and millet crops grown in Burkina Faso, Cameroon, Chad, Ethiopia, Mali, Niger and Sudan, and the expansion of ...

The Parasitic Weeds of the Orobanchaceae
2013This chapter outlines the most important members of the Orobanchaceae occurring as weeds of agriculture worldwide, the holoparasitic broomrapes (Orobanche and Phelipanche species), the hemiparasitic Striga species and finally a few less important hemiparasites including Alectra, Aeginetia and Rhamphicarpa species.

Population Diversity and Dynamics of Parasitic Weeds
2013Knowledge of the genetic diversity of parasitic weed populations is important in any attempt to develop resistance-breeding strategies for the relevant host crops. Moreover, comparative genetic diversity studies of parasite biotypes in natural habitats and crop fields are important for clarifying the evolutionary path from wild parasitic plants to ...
