Natural metabolites for parasitic weed management

Pest Management Science, 2009
AbstractCompounds of natural origin, such as phytotoxins produced by fungi or natural amino acids, could be used in parasitic weed management strategies by interfering with the early growth stages of the parasites. These metabolites could inhibit seed germination or germ tube elongation, so preventing attachment to the host plant, or, conversely ...

Suicidal germination for parasitic weed control

Pest Management Science, 2016
AbstractParasitic weeds of the genera Striga and Orobanche spp. cause severe yield losses in agriculture, especially in developing countries and the Mediterranean. Seeds of these weeds germinate by a chemical signal exuded by the roots of host plants. The radicle thus produced attaches to the root of the host plant, which can then supply nutrients to ...

Weed Management for Parasitic Weeds

2014
Parasitic weeds, representing more than 4,000 species of more than 20 higher plant families, are one of the most destructive and intractable pests to agricultural production in both developed and developing countries. Parasitic weeds cause heavy damage to numerous crops by reducing both crop yield and quality.

Parasitic weeds.

2009
AbstractThis chapter presents weeds (Cuscuta and Orobanche spp.) that are parasitic on lentil, briefly covering their biology, geographical distribution, and management (through chemical, cultural and integrated control methods).

Effects of Parasitic and Non-Parasitic Weeds on Sorghum

Experimental Agriculture, 1981
SUMMARYThe parasitic weed striga had significantly greater effects on sorghum yield components than non-parasitic weeds. Grain reduction caused by striga amounted to 65% compared with 32% reduction caused by non-parasitic weeds. Comparable reductions were also manifest in straw yield, grains/head and plant height of sorghum.

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

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 ...

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

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.

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 ...
