Abstract:
The effect of biocontrol agents and natural products on brown leaf rust, Puccinia recondita f.sp. tritici, of wheat were studied under greenhouse and field conditions in 1998/99 and 1999/2000 seasons. Under greenhouse conditions, application of Plant guard (Trichoderma harizianum), Rhizo-N (Bacillus subtilis) and the yeast (Saccharomyces cerevisiae) gave reasonable control of leaf rust severity with disease reduction percentages of 64.29, 57.14 and 19.14%, respectively. Field application of formulated natural products during two successive seasons gave effective control of brown rust disease. Natural oil, peppermint oil, jojoba oil, eucalyptus oil and chenopodium oil were the most effective treatments in reducing leaf rust severity and also in improving grain yield. All natural products significantly reduced the rust disease incidence in wheat by 55.5-98.2% and subsequently led to an increase in the grain yield that ranged from 8.5-51.8%. Of the biocontrol agents applied in the field, Plant guard was the most effective treatment followed by yeast and then Rhizo-N. These bioagents significantly improved grain yield and increased 100 kernel weight relative to the untreated control. Sumi-8 fungicide (diniconazole) showed complete protection against rust disease incidence in both greenhouse and field trials.
