فعالية مادة الفورفورال في مكافحة الذبول و تعقد الجذور الذي يصيب الباذنجان و الطماطم-البندورة تحت ظروف الظلة الخشبية في العراق

Abstract EN

Furfural at the rate of 4000 ppm was applied pre, during and 3, 6, 9.

12 days post planting for controlling the disease complex of root-knot nematode and f-'usarium oxysporum on tomato plants.

Another study was conducted to compare the cfficacy of furfural at the rate of 1000 and 4000 ppm with the nemaiicide cadusafus (Rugby) and the fungicide Chinosol (Bcltanol), and two bioagcnt fungi Trichoderma harzianum Rifani and Paecilomyces lilacinus (Thom) Samson.

All treatments were applied one week before planting for controlling the same disease complex of the first experiment on eggplant.

Results indicated that no galls or disease symptoms were observed when furfural was applied at the rate of 4000 ppm before planting in both experiments, while same rate when applied during and post planting caused plant toxicity and significantly decreased dry shoot and root weight of tomato plants compared to the untreated (control).

In the second experiment, the treated soil with T.

harzianum and the combination of rugby and bcltanol significantly decreased the disease and root- gall index of eggplant roots compared to other treatments including the control.
