| Abstract | ||||
| This study came out as results of many preceding primary studies from 1995 to 2004 years on chemical induced resistance as preventive technique from Insect born viruses diseases, this experiment was conducted For two fall season from 2005- 2006, in newly reclaimed sandy soil. Seeds of four tomato commercial F1 hybrids were sown in foam try on May 1st in the two season. On 15th June seedling were transplanted into field. On the day of transplanting, half of seedling were foliar treated with complex chemical induced resistance compound and repeated every 15 days. Data of Disease incidence, average fruit weight, fruit taste index, early yield, total yield and marketable yield were recorded. All recorded data were subject to statistical analysis by SAS computer program. More over, data of production costs, net return and other economic indicator was collected by questioner method on tomato growers in the investigated region. The results showed that all recorded data were improved significantly by chemical induction of resistance in all four cultivars through both growing season. Meanwhile, the response rate was differed up on cultivars and its base resistance level. Up on the results, it could be concluded that, the application of chemical induction of resistance not only prevent the viruses diseases infection, development and effects in tomato but also improve productivity, fruit quality and also, increasing both grower returne and consumer buying ability. So it could be the ideal solution to control insect born viruses such as Tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV) in fall tomato.
