Trichoderma harzianum in combination with carbendazim for integrated control of rice seedling blight
Control efficacies of Trichoderma harzianum T<sub>S1</sub> in combination with carbendazim against rice seeding blight pathogens were investigated, and induced resistance of rice to the disease was conducted. Activities of POD, PAL, PPO and SOD in root extracts from T. harzianum T<sub...

| description | Control efficacies of Trichoderma harzianum T<sub>S1</sub> in combination with carbendazim against rice seeding blight pathogens were investigated, and induced resistance of rice to the disease was conducted. Activities of POD, PAL, PPO and SOD in root extracts from T. harzianum T<sub>S1</sub> plus carbendazim treated seed plots were higher than those from untreated control. Simultaneously, seed treated with this combination counted to 82.25% disease control in growth chamber, which was 26.87% and 9.90% higher than that resulted by treatment with T. harzianum T<sub>S1</sub> and carbendazim alone. Field efficacies of combinations at three ratios exceeded the efficacies of the two agents used separately, indicating possible synergistic effects. Significant synergistic effect was observed in combination at ratio of 6 to 4, manifested by 44.46% and 11.66% higher efficacy than each agent. Seed treated with each combination resulted in a significant increase in shoot height, root length, total wet and dry weight compared with untreated control. T. harzianum T<sub>S1</sub> had the ability to colonize the rhizosphere and rhizoplane of rice plants with mean population sizes above 10<sup>4</sup> and 10<sup>3</sup> cfu·g<sup>-1</sup> fresh root, no significant treatment effects on colonization rate were found. |
