“…besides controlling plant pathogens, it also has other benefits. It also supports plant growth through several growth hormones (Martínez-Medina et al, 2014) and acts as an organic decomposer (Oktafiyanto et al, 2020;Thaha et al, 2020).…”

The aim of this research was to determine the effect of fourliquid organic substrates on the growth of four Trichoderma harzianum isolates and their effect on cucumber growth and yield. Randomized block design was used with 20 treatments and 3 replicates. The treatments consisted of control, tofu liquid waste, rice washing water, coconut water, and tapioca waste substrates each combined with four T. harzianum isolates. Variables observed were conidia density during decomposition, conidia late density, crop height, root length, root fresh and dry weight, crop fresh and dry weight, the first flowering, number of fruits per plant, and fruit weight. Result of the research showed that in the tapioca waste substrate, only T16 isolates was able to grow well with a maximum density of 6,70x107 conidia/mL. In the rice washing water substrate, conidia growth of the isolate was better than coconut water substrate with a maximum density of 6,25x107 conidia/mL. The best liquid organic substrate for growing media of T. harzianum was tofu liquid waste. On the 4th day with the tofu waste substrate, T16 isolate could achieve conidia density of 1,12x108 conidia/mL. The liquid organic substrate resulted from T. harzianum decomposition was not different on cucumber yield.

Using decomposers of fungi to increase the composting process is very necessary. The research aims to determine the potential of Trichoderma sp. Gorontalo local isolate as a decomposer of maize stover. The research was carried out from November 2022‒January 2023 at the Biological Agents Laboratory, Agricultural Plant Protection Center, Gorontalo Province Agricultural Department. This research determined the ability of six isolates of Trichoderma, namely TZ11DI1 (T. asperellum), TZ21BN2 (T. breviconvenctum), TZ21BT1 (T. virens), TZ12PO1 (T. ghanence), TZ21DU1 (T. reesei), TZ21LU1 (T. dorothopsis), and control (EM4) to produce cellulase and as a maize stover decomposer. The parameters observed were the clear zone in the isolate growing media as well as the physical and chemical characteristics of the compost produced. The results showed that Trichoderma isolates produced cellulase and potential as a decomposer for maize stover, as indicated by the ability to increase NPK nutrient levels and reduce the C/N ratio of maize stover compost.

Integrated Management of Verticillium Wilt of Cacao

The vascular disease Verticillium wilt of cacao (Theobroma cacao), caused by the soilborne fungus Verticillium dahliae, is often qualified as a “minor” disease. However, it can cause severe losses locally, for example, in western Uganda and northeast of the Democratic Republic of Congo. This disease is difficult to control, notably due to an extended host range and prolonged survival in the soil. Therefore, Verticillium wilt must be addressed through an integrated disease management strategy as employed for other tree crops such as olive. Few studies, nonetheless, have focused on how to confront this disease in cacao. This paper aims to provide an overview of our knowledge on Verticillium wilt on cacao and the integrated disease management strategies for preventing and controlling it. Promising avenues based on findings in other crops that could be adapted to cacao are also explored. Good agricultural practices, genetic resistance, biological control, induced resistance, and the use of organic amendments with or without biocontrol agents are discussed. Moreover, the potential benefits of some of these solutions toward the resistance to other cacao diseases, abiotic stress, and nutrition improvement are presented.
