Notes on Taxonomy and Nomenclature

Top of page Raphanus raphanistrum is the universally accepted name for this common and widespread annual weed. The genus name is derived from the Latin, raphanis, a vegetable grown from antiquity, the species name is from the Greek, ra, which means quickly and phainomai, to appear, and refers to the rapid growth of this weed. Flora Europaea (Chater, 1981) distinguishes between a number of subspecies: susp. raphanistrum, subsp. microcarpus (Lange) Thell. and subsp. landra (Moretti ex DC.) are all weeds of cultivated land, while subsp. rostratus (DC.) Thell. and subsp. maritimus (Sm.) Thell. are found on sea shores and sandy coasts.


Top of page R. raphanistrum may behave as an annual, winter annual or biennial and has a large basal rosette of leaves. The fibrous root system is very extensive to a depth of 20 cm, spreading horizontally to 80 cm in all directions. Stems are erect or spreading (striate to angled in South Africa), much branched, 30 to 100 cm (to 200 cm in Australia), with short, stiff hairs especially at the base. Leaves are alternate, rough, lower deeply lobed with much enlarged terminal segment, upper narrower, entire to slight indentations, 8 to 20 cm long. The flowers have a perianth with four free segments in long terminal, corymbose racemes, petals pale yellow, rarely white, purple veins (occasionally petals reported to be pinkish or purplish, may be straw coloured in Scotland, UK), 1 to 2 cm across, pedicels, 1 to 2 cm. The fruit is a fleshy pod, spongy, long, narrow, cylindrical, 5 to 10 mm in diameter, 2 to 7 cm long, terminating in a 1-2 cm pointed beak, longitudinally ribbed, indehiscent, 2 to 10 seeds, constricted but without septum between seeds, lower pods often small and seedless, sections with seed break apart at constriction when mature. The seeds are globular, ovoid, reddish to orange-brown (dark brown in South Africa), 2 to 4 mm in diameter, covered with fine network of veins with shallow interspaces.


Top of page R. raphanistrum, probably European in origin, occurs as a weed on all continents, but is absent from tropical Western Africa and South and East Asia (Holm et al., 1997).

Top of page Various studies and observations to establish the habitat and soil preferences of R. raphanistrum have been contradictory. Records from the UK around the turn of the 20th century suggested that it preferred chalk and sandy soils, often being the dominant species on chalk. In Germany, Vogel (1926) classified it as an indicator of acid soils. In France, LeFevre (1956) suggested the link between wild radish and soil pH was a weak one and concluded that it was only a modest indicator of a requirement for lime. Today, in both the UK and the USA, R. raphanistrum occurs in crops on a wide variety of soil types.

Hosts/Species Affected

Top of page R. raphanistrum is a major weed of cereals, especially wheat, and particularly winter-sown wheat (Holm et al., 1997). It is also common in a number of vegetable crops, legumes, vineyards, horticultural crops, pastures and fodder crops. It is likely to occur in any crop within its geographical range.

Biology and Ecology

Top of page R. raphanistrum is an annual, or rarely biennial species which reproduces solely by seed. It is a prolific seed producer. In field studies in Australia, seed yields reached 17,275 seeds/m² (Reeves et al., 1981), and accumulated seed banks reached levels of 45,000 seeds/m² at some sites. Seed production by individual plants is density dependent, with increasing population densities of R. raphanistrum resulting in reduced production per plant, but an overall increase per unit area.

Seed populations in the soil exhibit protracted germination and Reeves et al. (1981) estimated that in a single season one half of the seeds in the soil germinated. In Australia, germination usually occurs after autumn rains, but 'flushes' of germination occur throughout the year after rain. In the UK, the peak period of germination is in March and April, but seedlings continue to appear until late autumn (Roberts and Boddrell, 1983). Piggin et al. (1978) concluded that this sporadic germination may be the result of the gradual, but continuous breakdown of buried seed pods which have an inhibitory effect on seed germination.

In laboratory germination tests, R. raphanistrum has been shown to germinate over a range of temperatures, but was most responsive to fluctuating temperatures. Mekenian and Willensen (1975) in the USA, showed that the after-ripening requirement was completed in less than 6 months and that germination was generally greater in the dark. Cheam (1984, 1986) found that seeds from southern Australia had a greater level of initial primary dormancy than those from northern Australia, and Steinbauer and Frank (1954) recommended treating fresh seeds with potassium nitrate to break primary dormancy. In Germany, Lauer (1953) found that the minimum temperature for germination was 5°C, the maximum 35°C, with an optimum of 20°C.

The longevity of R. raphanistrum seed is increased by burial in the soil (Piggin et al., 1978). Kurth (1967) in Germany, reported that seeds could remain viable for between 15 and 20 years in the soil. In the UK, Chancellor (1986) reported a mean annual decline of 30% of the seed bank, corresponding to a half-life of 2 years.

Seed may be dispersed by a number of agents and is frequently a contaminant of commercial grain seed stocks. Seed may also be spread in irrigation water and is able to pass unharmed through the gut of many animals including birds and cattle (Holm et al., 1997).

Notes on Natural Enemies

Top of page No host specific natural enemies for this weed have been found, and any natural enemies would probably be pests of related crops.


Top of page R. raphanistrum has been reported as a weed of 45 crops in 65 countries (Holm et al., 1997) and is classified as a serious weed in nine countries and a principal weed in a further fourteen (Holm et al., 1991). In Germany, Otto and Hilbig (1987) reported decreases in the extent of many weeds, amongst them R. raphanistrum. These results are in contrast, however, to those of Klaassen (1995) who suggested that a five-fold increase in the area of rape in Germany in the preceding 10 years had lead to an increase in cruciferous weeds, including wild radish. In a study in the UK, Wilson and Cussans (1983) demonstrated that R. raphanistrum was one of the most competitive weed species against barley. In Florida, USA, complete control of wild radish throughout the growing season increased winter wheat yields by 39% (O'Byrne et al., 1986).

R. raphanistrum is an alternative host for a range of crop pests and pathogens. These include; the melon pathogen, Fusarium oxysporum f.sp. melonis (Zakeri and Banihashemi, 1996), beet western yellows luteovirus (Chod et al., 1997), the sugarbeet nematode Heterodera schachtii (Gleiss and Bachthaler, 1988), cucumber mosaic cucumovirus (Dikova, 1989), Pieris rapae (Garcia, 1988) and Nezara viridula (Jones and Sullivan, 1982).

Ingestion of R. raphanistrum by sheep and cattle may taint milk and if bread wheat becomes contaminated with large quantities of R. raphanistrum seed, 'bread poisoning' may result (Holm et al., 1997).


Top of page In Mexico, leaves of R. raphanistrum may be eaten by humans during food shortages (Holm et al., 1997). It may have some value in biological control programmes because of its ability to attract natural enemies of the cabbage aphid, Brevicoryne brassicae (Cheam and Code, 1995).

Prevention and Control

Top of page Introduction

The protracted period over which germination of R. raphanistrum may occur makes its complete eradication from crops difficult and necessitates careful consideration of the optimum time for cultural and chemical control measures. Early treatments are usually the most successful in grain crops, but allow late germinating weeds to set seed and contaminate the harvest. Later treatments result in greater competition from R. raphanistrum leading to reduced yields (Holm et al., 1997). When infestations are severe, more than one annual control treatment may be necessary.

Cultural Control

Cultural control practices must normally be combined with chemical treatments to ensure effective control of this weed. In trials in Victoria, Australia, the emergence of R. raphanistrum was greatest on direct-drilled plots, least on those moldboard ploughed to a depth of 15 cm and intermediate where the soil was scarified to a depth of 3 cm (Donaldson and Code, 1981). Whilst moldboard ploughing is able, due to the depth of burial of seeds, to significantly reduce emergence of R. raphanistrum, it does dictate that subsequent cultivations should be shallow to avoid the return of viable seed to the surface. In further trials in Victoria, Code and Donaldson (1996) showed that moldboard ploughing followed by cultivation to 80 mm or direct drilling could reduce wild radish populations to levels below the economic threshold for spraying. Due to the increased rate of loss of viability of seeds at the soil surface, direct drilling will lead to a rapid exhaustion of the soil seed bank where chemical control is able to prevent reseeding of establishing plants.

Soil solarization may provide effective control of R. raphanistrum (Rubin and Benjamin, 1983; Cartia, 1985).

Chemical Control

Cereals - R. raphanistrum is very sensitive to the standard 2,4-D and MCPA, bu ta range of herbnicides are also used. In field trials in winter wheat in Belarus, isoproturon gave 100% control (Soroka et al., 1995). In Georgia, USA, early season applications of bromoxynil and thimeturon [thifensulfuron] controlled R. raphanistrum in winter wheat. Metribuzin, 2,4-D dimethylamine and MCPA applied late season were equally effective (Schroeder, 1989). Bentazone applied post-emergence gave fair to good control (Nichols et al., 1983). In South Africa, triasulfuron provided 89-100% control in wheat and barley (van Biljon et al., 1988). In Victoria, Australia, bromoxynil + MCPA applied 6 weeks after sowing gave 95% control, metribuzin + methabenzthiazuron gave 88% control and dicamba + MCPA-amine gave 70% control (Code and Reeves, 1981).

Lupins - in Western Australia, control of R. raphanistrum in lupins was obtained with a post-emergence application of simazine applied 2 to 5 weeks after sowing (Gilbey, 1990). Good control has also been demonstrated with post-emergence application of diflufenican (Buerger, 1986) and linuron (Porter et al., 1988).

Soyabeans - in soybean fields infested with wild radish in Romania, imazethapyr applied post-emergence at the leaf rosette phase gave best control (Chirita et al., 1993). In France, 100% control was achieved with oxadiazon (Regnault, 1986).

Other recommendations include thiazopyr + oxyfluorfen in perennial crops (Warner and Holmdal, 1995), triflusulfuron in sugarbeet (Simonteit, 1992) and atrazine in maize (Marcondes and Kashiwakura, undated). Lorenzi (1984) and Mamarot and Rodriguez (1997) provide suggestions for use of herbicides and herbicide mixtures in a wide range of crops in Brazil and France respectively. Lorenzi indicates resistance to EPTC and trifluralin, and only moderate susceptibility to butylate, vernolate, butachlor, cyanazine, simazine, pendimethalin and oryzalin.
