“…These very consistent results across the various plant taxa tested indicate that, as expected, the volatility and concentration of bioactive chemicals released during plant residue decomposition in soil increases with increasing temperature (Gamliel and Stapleton 1993;Stapleton and Bañuelos 2009). Also, given the statistically significant interactions of the [amendment] and [temperature] factorial effects tested with S. rolfsii and P. ultimum (but not with M. incognita), the targeted phytopathogens were shown to incur more harm from simultaneous application of the dissimilar stress sources, i.e., chemical and temperature, than from either stress source alone.…”

“…As with most bioactive chemicals, including synthetic pesticides (Stapleton 2000) and brassicaceous and alliaceous plant residues (Gamliel and Stapleton 1993;Mallek et al 2007;Stapleton and Duncan 1998), deleterious activity of the tested poaceous amendments increased with increasing soil temperature.

“…Sensitivity of S. rolfsii to treatments was determined by retrieving and surface-disinfesting the 30 sclerotia from each container, then incubating them on potato dextrose agar plates to determine germinability. Effects on P. ultimum were determined by sampling soil from containers, then air-drying and spreading aliquots on a selective agar medium, as described previously (Gamliel and Stapleton 1993). Fungal colonies were identified and enumerated after incubation.…”

“…In previous experimentation with residues of brassicaceous (Gamliel and Stapleton 1993;Stapleton and Duncan 1998) and alliaceous (Mallek et al 2007) crop plants as soil amendments, biocidal activity was shown to increase with increasing soil temperature. We also reported that cover cropping with a sorghumsudangrass hybrid [Sorghum bicolor (L.) Moench x Sorghum sudanense (P.) Stapf.…”

Deleterious activity of cultivated grasses (Poaceae) and residues on soilborne fungal, nematode and weed pests

et al. 2009

Experiments were conducted in laboratory bioreactors and in field plots to test effects of certain cultivated members of the grass family (Poaceae = Gramineae), including wheat (Triticum aestivum cv. Yolo), barley (Hordeum vulgare cv. UC337), oats (Avena sativa cv. Montezuma), triticale (X Triticosecale), and a sorghum-sudangrass hybrid (Sorghum bicolor x S. sudanense = "sudex", cv. Green Grazer V) for soil disinfestation potential. Soilborne pest organisms tested for effects on survival and activity included the phytopathogens Sclerotium rolfsii, Pythium ultimum and Meloidogyne incognita, and a variety of weed taxa. Following soil amendment, bioreactors were incubated for 7 days at ambient (23°C) or elevated, but sublethal (38°C day/27°C night), soil heating regimens. Addition of each of the poaceous amendments to soil at 23°C resulted in inconsistently reduced tomato root galling (49-97%) by M. incognita, or reduced recovery of S. rolfsii and P. ultimum (0-100%) fungi in soil, after 7 days' incubation (P ≤ 0.05). When the organisms were exposed to the poaceous soil amendments at the 38 o / 27 o temperature regimen, nematode galling and recovery of active fungi were consistently and significantly reduced by 98-100%. These results demonstrated feasibility of soil disinfestation ("biofumigation") by activity of poaceous amendments, further aided by combining plant residues with soil heating (e.g. solarization). Results from three field experiments with sudex cover crops, conducted throughout the growing season, demonstrated biocidal activity on a range of weedy plants, including Amaranthus retroflexus, Calandrinia ciliata, Cerastium arvense, Digitaria sanguinalis, Echinochloa crus-galli and Poa annua. Both shoots and roots of sudex provided allelopathic weed biomass reductions of 35-100%, and for at least 106 days after shredding. Deleterious activity of shredded residues incorporated in soil was less persistent. These properties in poaceous crops can be useful for soil disinfestation;

“…Therefore, there is a clear need to develop alternative practical, safe and effective management strategies that can shorten the time that no host plants can be grown. Candidate methods include solarization (Gamliel & Stapleton, 1993;Katan, 1981), organic amendments (Conn, Tenuta, & Lazarovits, 2005;Gorissen, van Overbeek, & van Elsas, 2004;Lazarovits, Tenuta, & Conn, 2001) and Biological Soil Disinfestation (BSD). BSD is a new method, first described by Blok, Lamers, Termorshuizen, and Bollen (2000).…”

Biological Soil Disinfestation (BSD), a new control method for potato brown rot, caused by Ralstonia solanacearum race 3 biovar 2

et al. 2007

The potential of Biological Soil Disinfestation (BSD) to control potato brown rot, caused by Ralstonia solanacearum race 3 biovar 2, was investigated. BSD involves the induction of anaerobic soil conditions by increasing microbial respiration through incorporation of fresh organic amendments (here: grass or potato haulms) and by reducing re-supply of oxygen by covering with airtight plastic sheets. Control treatments were left without cover and amendment, or amended without covering or covered only without amendment. The effect of BSD on survival of R. solanacearum was tested at three different scales: in 1-l glass mesocosms under laboratory conditions, in 1.2-m-diam microplots positioned in an outdoor quarantine field, and in a naturally infested commercial field. Within a few days, anaerobic conditions developed in the BSD-treated soils. In the mesocosm and microplot experiment, anaerobic conditions persisted till the end of the 4-week experimental period. In the field experiment, the period of anaerobiosis was shorter due to birds damaging the plastic cover. In all three experiments, BSD reduced soil populations of R. solanacearum significantly by 92.5% to >99.9% compared to the non-amended and uncovered control treatments. In the field experiment, BSD also resulted in a significant reduction of R. solanacearum survival in potato tubers buried at 15 or 35 cm and in the rapid decomposition of superficially buried potatoes remaining after harvesting, thus destroying an important inoculum reservoir of R. solanacearum. The treatments with grass amendment only or covering with only plastic did not result in anaerobic conditions and did not decrease R. solanacearum populations during the experimental period. PCR-DGGE analyses of 16S-rDNA from soil samples of the various treatments in the mesocosm and microplot experiments revealed that BSD hardly affected bacterial diversity but did result in clear shifts in the composition of the bacterial community.
