“…Similarly, Aphanomyces euteiches, the causative agent of root rot of pea, was suppressed by volatiles released during the breakdown of cabbage tissue in the laboratory (Lewis and Papavizas 1971b). Field experiments in which white mustard (Sinapis alba L.) significantly reduced root rot (A. euteiches) in pea plants grown the following year, further supported these early glasshouse experiments (Muehlchen et al 1990).…”

Soilborne fungal diseases threaten the viability of the Australian processing beetroot industry. Globally, Pythium spp., Aphanomyces cochlioides and Rhizoctonia solani are the predominant soilborne fungal pathogens responsible for a root rot complex in beet crops. In Australia, the disease problems have been exacerbated in recent years because crops are now grown virtually year round, and under environmental conditions favourable to infection. This has lead to increased inoculum levels in soils sown to beetroot. Moreover, nowhere in the world does there seem to be a single strategy that is completely efficacious in controlling these pathogens, so an effective management strategy will almost certainly involve a combination of tactics. The most likely combination seems to involve fungicide seed treatments, rotations of gramineous or biofumigant crops and the use of disease-resistant varieties of beet. The first of these, fungicidal seed dressings, are a cost-effective means of reducing pathogen inoculum and protecting young beets from infection. Hymexazol may be particularly useful in the Australian system, since it is active against both Pythium and Aphanomyces. To combat Rhizoctonia, it should be applied in combination with either pencycuron or toclophos methyl. Second, rotations of gramineous crops, such as maize or oats, or biofumigant brassica crops, such as white mustard, brussel sprouts or cabbage should also reduce the build-up of inoculum and offers a tactic to relieve the problem in the longer term. Third, alternative beetroot cultivars with resistance to Rhizoctonia have now been developed in USA breeding programs and should be considered by the Australian industry. Resistant varieties are potentially very useful since they offer a long-term approach to disease management that can be easily incorporated into existing production systems. Fourth, the alteration of sowing dates to avoid periods of high disease risk (e.g. confining sowing to the cooler, drier months) needs to be seriously considered by the Australian industry if it is committed to disease management. There is also evidence to suggest that seed priming may warrant consideration as a tool to use in combination with fungicide dressings to reduce disease in young plants. Biological seed treatments and soil fumigation appear to be tactics of limited value to the Australian beet industry.

“…Sowing wheat in rotation with other crops improves seed yield compared with monoculture. Rape seed has compounds that are enzymatically hydrolyzed upon tissue disruption to release a variety of biologically active compounds, including isothiocyanates, which are toxic to certain insects (Blau et al, 1978), fungi (Muehlchen et al, 1990), nematodes (Mojtahedi et al, 1993) and weeds (Bell and Muller, 1973). Also, Altieri and Doll (1978) reported that it is a potent allelopathic crop and has allelopathic effects on weeds.…”

The objective of this study was to determine the influence of crop rotation and crop residue management on wheat yield and yield components with four crop rotations [wheat-wheat-wheatrapeseed-wheat (WWWRW), wheat-sugar beet-wheat-potato-wheat (WSWPW), wheat-maize-wheatpotato-wheat (WMWPW) and wheat monoculture for the whole period (WWWWW)] and three levels of retaining crop residues to soil (0, 50 and 100% produced crop residues to soil) were allocated to main and sub plots, respectively. Results showed that the effect of different crop rotations on the plant height, spike number per square metre, seed number per spike; economic yield and biological yield of wheat were significant. There were significant differences between different levels of crop residues to soil for wheat spike length, spike and seed number. Interaction between different crop rotation and returning crop residues to soil had significant effect on plant height, spike length, seed number, economic and biological yield in wheat. Wheat seed yield were increased 37, 21 and 33% in WWWRW, WSWPW, WMWPW compared with wheat monoculture, respectively. As this application of crop residues affected wheat yield and yield components, the highest yield was observed in 100% returning all crop residues to soil. Although the application of adding crop residues to soil is a feasible alternative for farmers to enhance yield, the quantity and quality residue is the main factor for incorporation. Sowing wheat in rotation with rapeseed improved seed yield compared with monoculture.

“…Amendments with cruciferous residues can suppress certain soil-borne pathogens and root diseases (Muehlchen et al, l990;Gamliel & Stapleton, l993;Angus et al, 1994). It was speculated that sulfurcontaining volatile compounds, released during the breakdown of glucosinolates in crucifer tissues, may act as soil fumigants effective against soilborne pathogens (Lewis & Papavizas,l971;Brown et al,l99l).…”

Solarization and natural heating of irrigated soil amended with cruciferous residues for improved control of Macrophomina phaseolina

1997

The efficacy of summer irrigation and soil solarization combined with cruciferous residues was tested against the dry root rot pathogen Macrophomina phaseolina in an arid climate. In irrigated amended soil, polyethylene mulching during May increased the soil temperature to 57ЊC and 50ЊC at depths of 0-15 and 16-30 cm, respectively. As a result, within l5 days the population of M. phaseolina was almost eradicated (93-99%) at both soil depths. A considerable reduction (75-96%) was also achieved by natural heating of irrigated soil (46-53ЊC) for l5 days after amending with cruciferous residues. Mulching alone was only partially effective (69-89% reduction). These results suggest a new approach to controlling soil-borne pathogens in hot, arid regions by combining summer irrigation with soil amendment. Amendment with residues alone or in conjunction with soil solarization also increased the population of lytic bacteria against M. phaseolina.
