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.

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 ...

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.

Attachment of the parasitic weed dodder to the host

Protoplasma, 2002
The parasitic weed dodder (Cuscuta pentagona L.) invades a number of potential host species, but the mechanisms responsible for ensuring tight adhesion to the wide variety of host surfaces have yet to be identified. In this study, a battery of microscopy protocols is used to examine the host-parasite interface in an effort to deduce these mechanisms ...

The Parasitic Weeds of the Orobanchaceae

2013
This 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.

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 ...
