| Abstract | ||
| Pot experiments using T.harzianum and the Vydate that compatible with it for control of Wheat galls disease on wheat cultivar Sham 6 were achieved.The results showed all the rate of solid and filtrate bioagent T.harzianum lead to earlier seeds germination and increase in germination percentages as well as superior on vegetative and reproductive features with reduction in infection features and increase in some systemic resistance markers. The lowest germination period was 8.5 days after cultivation while highest germination percentage was 85% at the 0.3% of solid T.harzianum inoculum,compared to 11 days and 76,66% in control, respectively.In the same T.harzianum rate (0.3%),maximum plant length was 55.83 cm plant-1 .In Vydate treatment all plants were died, while in T.harzianum (0.3%) + Vydate ,highest tillers number and leaf area were 5.53 tillers plant-1 and 29.06 cm, respectively. Although there is no any infection percentage in all rates of T.harzianum with vydate, highest yield was recorded in present of only T.harzianum,maximum grains number and 1000 grains weight at 0.3% of solid T.harzianum inoculum resulting in 40.33 grains spikes-1 and 40.8 gm, compared to 13.66 grains spikes-1 and 26.4 gm in control. All T.harzianum treatment (without vydate) showed a significant increase in peroxidase, Chitinase and lipase compared to control while T.harzianum treatment (with vydate) showed a significant increase in peroxidase and Chitinase , maximum peroxidase was 18.0 unit/ml in T.harzianum filtrate 0>6%+vydate while highest chitinase and lipase activities were 0.209 and 5.25 unit/ml in T.harzianum(0.2%), respectively. | ||
