Abstract

Abstract: Cucumber Fusarium wilt is one of common and serious soil-borne fungal disease in protected cucumber cultivation, and biological control of Cucumber Fusarium wilt is of great significance to the safe production of cucumber. In this study, the effect of application modes of three Trichoderma strains on the seedling quality characteristics and control effects against fusarium wilt of cucumber through pot culture were evaluated. The three Trichoderma strains were Trichoderma asperellum 525, Trichoderma harzianum 610, and Trichoderma pseudokoningii 886 with anti-Fusarium oxysporum activity. The three application modes of the 3 strains were T1 (simultaneous inoculation of Trichoderma and pathogen), T2 (inoculation of Trichoderma first, and then pathogen 2 days later) and T3 (inoculation with pathogen first, and then Trichoderma 2 days later). The results showed that the control efficacies of Trichoderma against Cucumber Fusarium Wilt were all above 64.78%, and the application mode T2 of T. pseudokoningii 886 was the most effective, with control efficacy of 81.54%. Compared with CK1 (inoculation with pathogen alone), vigorous seedling index, chlorophyll content, root activity, nitrate nitrogen content, nitrate reductase activity, root total absorbing area of cucumber seedlings significantly improved. Among the three application modes, T2 had the most promoting effect on the above 6 indicators of the cucumber seedlings at 8-14 d after sowing. T. pseudokoningii 886 had significant increased vigorous seedling index, chlorophyll content, root activity, nitrate nitrogen content, nitrate reductase activity, root total absorbing area of cucumber seedlings at 14 days after sowing, by 210.06%, 74.39%, 37.23%, 54.45%, 88.00% and 51.11%, respectively. The results showed that the three Trichoderma strains can improve the physiological metabolic activity and enhance the seedling quality, therefore restrain the incidence of Cucumber Fusarium wilt. Application of Trichoderma preparations in advance will be beneficial to the disease control of cucumber seedlings and lay the foundation for the improvement of the yield and quality of Cucumber in the later period.

Key words: Trichoderma, cucumber, Fusarium wilt, physiological characteristics, vigorous seedling index
