“…In this study, the mycelium of the fungus G. boninense grew on the ninth day after planting. This is also following research conducted by Dendang (2015) that Ganoderma mycelium grows around 7-12 days. To ensure that the isolated Ganoderma mushroom is G. boninense, macroscopic and microscopic observations were made.…”

This study aims to determine the type of Trichoderma fungus that can inhibit the growth of G. boninense and determine the percentage of inhibition of Trichoderma on the growth and development of G. boninense. This research was conducted at the Central Laboratory of the STIPER Agricultural Institute Yogyakarta in February-March 2022. G. boninense samples were taken from three different plantation locations belonging to residents of Aek Paing Atas Village and Aek Paing Bawah Satu Village, Kec. Rantau Utara, Kab. Labuhan Batu and Aek Janji Village, Kec. Rantau Selatan, Kab. Labuhan Batu, North Sumatra. Trichoderma samples were taken from Naga Soppah Village, Naga Harjo Village and Bahung Kahean Village. The research method used is descriptive by identifying antagonistic (Trichoderma) and pathogenic (G. boninense) fungi. Data on the percentage of inhibition of fungi were analyzed quantitatively. Fungi macroscopic and microscopic characterizations were analyzed qualitatively. The results showed that the Trichoderma fungus that could inhibit the growth of G. boninense was T. harzianum. The highest percentage of inhibition power of T. harzianum (Naga Soppah Village) against G. boninense (Aek Paing Bawah Satu village) was 30%.

Priming is a seed-soaking technique to increase seed viability and also suppress pathogens' growth. Magnaporthe oryzae is one of the pathogens in rice plants that causes leaf blast disease. The high rice consumption each year in Indonesia is not proportional to the amount of rice plant production, which is affected by the growth of pathogenic fungi. This study aims to determine the viability and percentage inhibition of Bacillus subtilis and Trichoderma harzianum against the growth of the pathogenic fungus Magnaporthe oryzae on local West Sumatra rice varieties Ceredek, Pandan Pulau, and Batang Sungkai. The research was conducted by testing the viability of microbes by counting the number of colonies and testing microbial antagonists with the Dual Culture method on seven days of observation. The results showed that Bacillus subtilis and Trichoderma harzianum could inhibit the growth of the pathogen M. oryzae, which causes leaf blast disease. The viability of Bacillus subtilis after biopriming for 48 hours was most significant on Ceredek variety, which was 15.9x106 cfu/g, and for Trichoderma harzianum on Pandan Pulau variety, which was 0.4x106 cfu/g. The most significant inhibition percentage of Bacillus subtilis and Trichoderma harzianum was obtained in Ceredek rice with a value of 30.13% (medium category) and 63.04% (high category).

Sengon (Falcataria moluccana) cultivations still have to face threats from plant diseases. Diseases can be found in nurseries and plantation. Biological agents can be used to control various types of plant diseases and have various advantages. The use of biological agents in forestry plantations must consider the aspects of effectiveness and efficiency. This study aims to examine the effect of various treatment of control technology packages on the incidence of major diseases, and to determine the financial feasibility of various disease control technology packages for sengon in nurseries. The research was conducted through interviews to explore cultivation techniques and production costs. In addition, experiments were carried out on the application of various disease control strategies using commercial formulations of biological agents. The commercial formulations of biological agents used were Rhizomax, Primagrain, Trichowish, Kayabio, Bio-Hara Plus, and fungicide Dithane M-45 80 WP. There were two treatment packages of new technology that have an effect on increasing the growth of sengon at the beginning of growth stage, namely P1 (BioHara Plus and KayaBio) and P2 (Rhizomax and Primagrain) treatments. All treatments of the new technology package had no significant effect on increasing the survival rate and suppressing the incidence and severity of disease in sengon seedlings. All new technology package treatments can generate profits even though the value is smaller when compared to existing technology treatments. All the new technology package treatments have an R/C ratio of more than 1 so that they are feasible to be applied by farmers.
