Abstract:

          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 Fusarium oxysporum on tomato plants. Another study was conducted to compare the efficacy of furfural at the rate of 1000 and 4000 ppm with the nematocide cadusafus (Rugby) and the fungicide Chinosol (Beltanol), and two bioagent fungi Trichoderma harizianum Rifani and Paecilomyces lilacinus (Thom.) Sampson. All treatments were applied one week before planting for controlling the same disease complex of the first experiment on eggplant. Results indicated that no gall 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. harizianum and the combination of rugby and beltanol significantly decreased the disease and root-gall index of eggplant roots compared to other treatments including the control.
