Parasitic weeds on cool season food legumes

1988
The most important parasitic weed which attacks cool season food legumes is broomrape (Orobanche sp.). It is endemic in Mediterranean regions but its area of distribution can expand as host crops spread into other zones. Most of the research carried out on Orobanche physiology has focused on the germination of seed; recent data suggest a complex ...

Parasitic Weeds: A World Challenge

Weed Science, 2012
While witchweed is nearing eradication in the United States, it continues to thrive in other parts of the world, especially in Africa, together with other witchweed species. The continuing problems from witchweeds and other parasitic weeds, the broomrapes, dodders and mistletoes, are outlined, including their extent, the degrees of damage caused, and ...

Parasitic Weeds

2017
Parasitic weeds could be considered as a separate world within the weed 'universe'. This is because of their unique systems that allow them to interact with the host plants in almost every phase of their life-cycle. This chapter considers parasitic weeds in Europe the nature of the problem, the unique features of their biology and implications for ...

Parasitic weeds of arable land

1982
This 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.

Witchweed: a Parasitic Weed of Grain Crops

Outlook on Agriculture, 1990
The 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 ...

Advanced Technologies for Parasitic Weed Control

Weed Science, 2012
Parasitic weeds such asPhelipancheandOrobancheare obligate holoparasites that attack roots of almost all economically important crops in semiarid regions of the world. A wide variety of parasitic weed control strategies (chemical, biological, cultural, and resistant crops) has been tried. Unfortunately, most are partially effective and have significant

Protection of crops against parasitic weeds

Crop Protection, 1991
Abstract 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 ...

Population Diversity and Dynamics of Parasitic Weeds

2013
Knowledge 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 ...
