“…Weather station data from Indiana indicate that the period of overlap of high SCN activity and winter annual weed growth may be limited to a few weeks in early fall and late spring when soil temperatures favor both nematode activity and weed growth (6,42). These data suggest that soil temperatures in Indiana may be adequate for SCN to complete a life cycle in the fall and/or spring on compatible winter annual weeds when soybean is not present in the field and was recently confirmed by Creech et al (12) (Fig. 2).…”

Role of Winter Annual Weeds as Alternative Hosts for Soybean Cyst Nematode

Soybean cyst nematode (Heterodera glycines Ichinohe, SCN) has been reported to parasitize a broad range of host plants, encompassing nearly 150 legume and non‐legume genera representing 22 plant families. Several SCN host species are common winter annual weeds in US soybean production fields and include purple deadnettle (Lamium purpureum L.), henbit (Lamium amplexicaule L.), field pennycress (Thlaspi arvense L.), shepherd's purse [Capsella bursa‐pastoris (L.) Medik], common chickweed [Stellaria media (L.) Vill.], and smallflowered bittercress (Cardamine parviflora L.). The influence of winter annual weed management on SCN population densities has received little attention to date and warrants further investigation by multidisciplinary research involving weed scientists, nematologists, and soybean production specialists.

“…Similar results for soyabean cyst nematode were found for the winter fallow period in soyabean production systems of the Midwest of the USA. Population densities of Heterodera glycines were minimally influenced even by multiyear differential weed management strategies (Mock et al ., ), despite the capacity of the nematode to reproduce on those weeds under commercial production conditions (Creech et al ., ).…”

Quantitative reproductive potential of Heterodera schachtii on weeds typical for late summer fallow in sugar beet rotations

In Europe, sugar beet is often produced in a 3-year rotation with cereals, leaving stubble fields fallow from cereal harvest until primary tillage in autumn in the year prior to sugar beet production. The weed flora on such fields could include host plants of Heterodera schachtii that is one of the most important pests of sugar beet. Crop sequences with non-hosts and cover cropping with resistant cruciferous hosts during this period have been crucial for its management. Availability of resistant and tolerant sugar beet cultivars could entice growers to forego cover cropping, exacerbating weed problems during the fallow period. The objective of this study was to determine the reproductive potential of H. schachtii on weeds that develop during this period. Under glasshouse conditions, reproduction on 39 plant species was compared with that on oilseed radish and sugar beet of differing nematode host status. In 2 years in field microplots, 18 previously tested species were grown in H. schachtiiinfested soil during the typical fallow period at 60 plants m À2 , and nine of these species were also grown at 180 plants m À2 . There were variable results between years after 8 weeks of growth, but most weeds allowed lower reproduction (<10%) than the susceptible sugar beet; only Stellaria media at 180 plants m À2 and Thlaspi arvense at both plant densities increased nematodes. Such weed densities may seldom occur under commercial conditions; thus, weed management for nematological considerations during the stubble period may have limited importance.

“…Winter weeds such as henbit (Lamium amplexicaule), chickweed (Stellaria media), and purple deadnettle (Lamium purpureum), commonly found in soybean production fields during the noncrop period, are hosts of SCN (15). The presence of SCN, host plants, and soil temperatures above the nematode's developmental threshold may lead to an increase in nematode numbers prior to planting soybean (5).…”

Potential for Soybean Cyst Nematode Reproduction on Winter Weeds and Cover Crops in Tennessee

The soybean cyst nematode (SCN), Heterodera glycines, is a major yield limiting pest of soybean (Glycine max). Current SCN management strategies include resistant soybean varieties and rotation with non-host crops. Increased adoption of the early soybean production system (ESPS) combined with a greater incidence of winter weeds from no-tillage practices may increase the population density of SCN during the noncrop period since several winter weeds and cover crops are hosts for SCN. A field experiment with a split-strip design was conducted over three years to evaluate whether SCN reproduced on weeds and cover crops during the noncrop period. Winter weeds and crimson clover roots were examined for females and cysts with eggs. The soil was sampled to determine if an increase in SCN egg population density occurred. We found no indication of SCN reproduction on winter weeds during the noncrop period or on the cover crop crimson clover. Accepted for publication 2 November 2006. Published 26 February 2007.
