Abstract
Glasshouse and field experiments were conducted to determine the effects of biocides and rotation breaks on deleterious soil organisms associated with the poor early growth and subsequent yield decline of sugarcane grown in continuous monoculture. Fumigation of a soil that had been under sugarcane monoculture with minimal breaks for more than 30 years markedly improved the health and growth of the sugarcane sett and shoot root systems, increased the growth of the primary shoot and stimulated more and larger secondary shoots. It also reduced populations of culturable fungi in the rhizosphere of the sett roots and reduced colonization of the sett and shoot roots by lesion nematode (Pratylenchus zeae). Exposure of the developing sett root system for 14 days to mono-cultured sugarcane soil was sufficient to significantly retard subsequent plant growth. In field experiments, fungicide and nematicide (mancozeb + aldicarb), when applied together to land under sugarcane monoculture, was as effective as fumigation in improving early sugarcane growth and increasing sugarcane yields. Rotation breaks (alternate crops, sown pasture, bare fallow) that were in place for 54 months, increased sugarcane establishment and increased sugarcane yields to levels similar to that obtained following fumigation of land under sugarcane monoculture. Fumigation of land that had been under the rotation breaks gave plant growth responses that were in addition to that achieved by the breaks alone. A mancozeb + aldicarb treatment was as effective as fumigation in increasing sugarcane yields after a bare fallow break but accounted for only a portion of the fumigation response following the crop and pasture breaks. Improved plant nutrition may be a factor in the fumigation response following the crop and pasture breaks. Plant growth responses to fumigation and the manocozeb + aldicarb treatments that were manifested in final sugarcane yields (after one years growth) were evident as plant growth responses (sett root, shoot root and primary shoot dry weight) measured 54 days after planting. The experimental results support the concept that when sugarcane is grown as a monoculture, deleterious fungi and nematodes retard plant establishment and early plant growth and that this leads to reduced sugarcane yields.
