Management of Tomato Damping-off Disease in the Nursery Using of Trichoderma asperellum

Abstract

The study was conducted during 2018−19 and 2019−20 to evaluate effectiveness of the Trichoderma asperellum liquid formulation for the management of tomato damping-off in the nursery. The experiment was conducted for two consecutive seasons in a randomized block design with seven treatments and three replications. T. asperellum formulation improved seed germination and controlled the damping-off diseases in tomatoes when compared with control. All the treatments performed better over control, in the first season, the antagonist’s application showed 75.75% seed germination; however, it was 60.13% in control. There was 10.93 to 20.38% seedling mortality due to disease which was comparatively lower than the control (26.98%). A similar trend of seed germination and disease incidence was observed in the second season. In addition to managing the disease, the antagonist certainly promoted vegetative growth which was reflected as increased shoot and root length in comparison to control during both seasons. During the first season, shoot length ranged 10.90–12.85 cm as compared to the control (8.72 cm) and root length ranged from 3.21–3.65 cm which was greater than the control. Almost a similar trend in the vegetative growth parameters of seedlings was observed during the second season. The present investigation showed that the tested antagonist’s formulation could efficiently manage the tomato damping-off as well as encouraged the vegetative growth of seedlings which ultimately ensured better and healthy seedling. This formulation can successfully be used through different methods to take care of tomato damping off.

Domiciliation of Trichoderma asperellum Suppresses Globiosporangium ultimum and Promotes Pea Growth, Ultrastructure, and Metabolic Features

“…T. asperellum ZNW enhanced the vegetative growth of pea plants that were planted in infested or non-infested soil due to its ability to promote plant growth, antagonize G. ultimum NZW, and its ability to induce the defense-related enzymes, and improve the concentration of photosynthetic pigment. These improvements resemble those reported on the growth parameter of tomato due to T. asperellum , which is used as a bioagent against damping-off disease [ 73 ].…”

Journey of Trichoderma from Pilot Scale to Mass Production: A Review

“…Before its application, appropriate moisture is required for its better multiplication. A study confirmed that Trichoderma-enriched compost used as a nursery bed amendment considerably enhanced the yield and growth of tomato seedlings [277]. Trichoderma-enriched compost also enhanced the soil fertility and increased the soil enzyme activity, indicating improved soil health.…”

Synergistic strategies for sustainable crop protection: harnessing soil solarization and biofumigants to combat damping-off pathogens in Solanaceous vegetable crops

“…Synthetic pesticides cause nearly two lakhs of deaths from poisoning each year, and 99% of them occur in developing countries (Arora et al, 2022). However, issues related to human and soil health, environmental hazards, and disturbed ecosystems pressurized the agriculturists to switch over towards the safer and eco-friendly plant protection approaches (Kumhar et al, 2022). One such technique is Soil solarisation which is an eco-friendly method adopted prior to planting where solar energy is used by covering soil with transparent plastic sheet to control soil borne plant pathogens (Kanaan et al, 2017).…”
