| Popis: | Field experiments were conducted in Northern Syria during the 1996/97 and 1997/98 cropping seasons to determine the effect of different control options on wilt disease parameters and lentil yields. The control options were sowing dates, host plant resistance and fungicide seed treatment. The disease parameters were: wilt onset, duration, per cent terminal wilt and areas under the disease progress curve. The experiments were carried out in a field infested with Fusarium oxysporum f. sp. lentis. Lentil genotype had a greater effect on the onset and duration of Fusarium wilt than planting date or fungicide seed treatment in both seasons. Per cent terminal wilt and areas under the disease progress curve were lowest during November plantings for all genotypes. Straw yields were correspondingly high for November plantings in both seasons. The correlation between per cent terminal wilt and area under the disease - progress curve with yield parameters was negative and significant. Since November planting reduced ... |
