“…Such a strategy may provide a means to manage the levels and distribution of Pachymetra spores in the soil. Croft and Saunders (1996) recorded higher numbers of Pachymetra spores closer to the row than in the inter-row and on the basis of this suggested that re-planting should be done in the old inter-row. However, this strategy gives little consideration to the large amount of energy required to generate a seedbed in the compacted inter-row area (Braunack et al, 1999).…”

“…Reduced tillage for planting sugarcane is being adopted by the industry to reduce the cost of planting and to implement a controlled traffic farming system (Braunack et al 2003, Braunack and McGarry, 2006, Garside et al 2004. Such a strategy is at odds with that proposed by Croft and Saunders (1996) for Pachymetra management. Thus it is important that there is no adverse effect of adopting a strategy that re-plants cane into the old row area from the previous cycle.…”

Land preparation for planting sugarcane (Saccharum inter-specific hybrid) generally consists of multiple tillage passes to remove the old stool and the compacted inter-rows. The next crop is usually planted in the old inter-row area to minimise the effect of Pachymetra chaunorhiza, a soil borne disease which builds-up under the old crop row. However, in order to adopt reduced tillage and not be adversely affected by soil compaction in the old inter-row it is necessary to replant into the old crop row. The hypothesis tested was: would reduced tillage and planting back in the old crop row in conjunction with rotation of resistant and susceptible cultivars minimise the effect of this soil borne disease on crop yield ? Field experiments were undertaken on Alfisol soils, near Tully in north Queensland and Bundaberg, south Queensland, Australia to compare

“…Known sugarcane root pathogens in Queensland include Pachymetra chaunorhiza (Croft and Magarey 1989), Pythium arrhenomanes (Croft and Magarey 1984) and various nematode species (Magarey and Croft 1995). Soils were assayed for Pachymetra chaunorhiza by assessing the percentage of rotted primary shoot roots (Croft and Magarey 1984;Magarey 1986) and in some cases by assessing soil oospore populations (Magarey 1989a(Magarey , 1989b. Pythium arrhenomanes was assayed by isolation from sugarcane root systems (Croft and Magarey 1984) or using a sorghum bait bioassay (Croft 1987).…”

Summary. The growth of sugarcane in soils from land monocultured with sugarcane, and from land which had either never been cropped with sugarcane, or just recently cropped, was compared under glasshouse conditions. In general, cane growth in new land soils was greater than in monocultured soil (shoot growth 7.4%, root growth 21.4%). Responses to soil pasteurisation were investigated in some soils and were greater in monocultured soils suggesting that root growth constraints were larger in the monocultured soil (210% response in monocultured soils v. 64% in new land soils). Assays for sugarcane root pathogens suggested that Pachymetra chaunorhiza was a major contributor to the old/new land growth responses, but it is unlikely that Pythium spp. were factors in the growth differences. Monitoring of other groups of organisms in soil from one site suggested that sugarcane monoculture may affect populations in the broader biological community.
