“…+ Bacillus subtillis) showed better performance reducing the incidence of moniliasis and obtaining the higher fruit weight. De Sousa et al (2021) evaluated five isolated Trichoderma spp., on seed treatment and seedling production of Theobroma cacao and found fungi incidence of 26.5% only in the control treatment, while incidence fungi was 0% for all Trichoderma isolates. Likewise, Seng et al (2014) reported a significant reduction of incidence of monilia infection by 11%.…”

Theobroma cacao is the main raw material to produce chocolate, as well as for use in the food, cosmetic, and pharmaceutical industries. However, Moniliophthora roreri is one of the most destructive fungal diseases and the main limiting of cacao production worldwide. Thus, this work aimed to assess the inhibitory effect of extracts of Zingiber officinale (T1) and Aloe vera (T2), and Trichoderma harzianum + Bacillus subtillis. (T3) on Moniliophthora roreri infection in Theobroma cacao; in addition, a control (T4) was also evaluated. Each treatment was applied to six plants of cacao. Incidence of monilia infection and fruit weight were monitored every 15 days (in total four periods) after the application of the treatment by spray. Significant differences (P<0.05) were found among treatments for incidence. It was observed that spraying entire cacao trees after two times (approximately 30 days) showed a reduction of monilia infection. After all periods, T1, T2, and T3 showed an incidence of monilia infection by 20.5, 17.7, and 14.9% respectively, compared to cultural control of 41.1%. This reduction of moniliasis infection translates into an increase in fruit weight average for T3 (8.4 kg), T2 (7.3 kg), and T1 (6.9 kg). In contrast, in the control (T3), the fruit weight average decreased by 5.3 kg. Biological control showed efficient management of pathogens as M. roreri. It is recommended to use such antifungal (Aloe vera) spray over at least 120 days which would decrease infection incidence even more.

“…The use of beneficial microorganisms, such as Trichoderma, can be applied to stimulate the development of seedlings. In addition to acting as disease control agents in several cultivated species, fungi of this genus are capable of promoting growth and inducing plant resistance to diseases [2][3][4][5][6][7] and resistance to salinity [8], with great environmental and economic importance for agriculture.…”

Trichoderma is a genus of fungi widely used in agriculture as a biocontrol agent and more recently as a plant growth promoter. We evaluated five Trichoderma isolates, in different application modes, throughout the development of jabuticaba seedlings. These included three isolates of the species Trichoderma asperellum (Tam01, Tam02, and Tam03) and two isolates of Trichoderma sp. (Tc and Tce) in four modes of application: via seeds; in applications on the pre-planting substrate; in monthly applications in the post-planting substrate; and their combination. The control treatment consisted of plants without the use of Trichoderma. Seedling height, collar diameter, and the number of leaves were evaluated monthly. Statistical analysis was conducted using data collected two, four, seven, and thirteen months after emergence. The application of Trichoderma promoted the growth of jabuticaba seedlings up to four months after emergence. The isolate Tam03 and the application via seeds were the treatments that most influenced the analyzed variables at four months. The use of Trichoderma stimulated the beginning of the development of jabuticaba seedlings.

“…The development of mixtures containing strains communicating with each other to maximise antibiotic production and disease control could be another approach in the improvement of control of soil-borne diseases (Becker et al, 1997;Davelos et al, 2004). According to De Sousa et al (2021), inoculation with Trichoderma increased the length of the radicle and hypocotyl and showed no fungi in the seeds. Some treatments increased the height and the plant root dry mass in seedlings.…”

The basic principles for the development of organic agriculture has been prescribed by the International Federation of Organic Agriculture Movements -IFOAM and the European Union (Commission Regulation No 209/91), on whose standards EU regulations are founded. The field of organic production at the international level and issues of seeds and planting material are regulated by the IFOAM Basic Standards 2002, which stipulates that seed and planting material used in organic agriculture has to be produced in line with the regulations applicable to organic crops. Unlike the conventional seed production, in organic seed production, there is a higher risk of contamination with pathogens, i.e. seedborne diseases. The aim of this study was to point out the existing methods of seed treatments in the organic production system in order to obtain healthy seeds. Seed-borne pathogens, including bacteria, fungi, viruses and viroids, are responsible for disease recurrence in subsequent cycles of seed multiplication and spread of diseases in new geographic regions. According to various authors, there are several classifications of treatments including physical treatments, application of natural compounds, such as plant extracts and oils, use of inorganic natural products and biological control (use antagonistic microorganisms). In order to overcome various pathogens different biocontrol strategies should be developed. Microorganisms can be used in diverse crop protection practices, i.e. several seed treatments can facilitate high levels of both disease control and production yield.
