Abstract

Gondangmanis guava production has decreased every year, this is due to pests and plant diseases and due to decreased land quality, either due to soil fertility or the absence of cultivation techniques applied to Gondangmanis guava plants. This is caused by several factors, including the lack of supply of agricultural production inputs, the absence of development of guava cultivation technology, the absence of post-harvest technology assembly for guava, and the absence of wider marketing of guava production. soil organic matter, physical properties and macronutrients contained in the land of gondangmanis guava growth. The decline in land productivity will affect the productivity of crop production. Based on this, the author intends to examine how much macro nutrients are available in the Gondangmanis guava growth medium and the soil characteristics of the Gondangmanis guava growing media. The survey and sampling were carried out in the village of Gondangmanis Badarkedung, Mulyo, jombang. Anali This study used a qualitative research using a survey system followed by random sampling of soil at a depth of 0-20 cm. The soil sample is then analyzed in the Integrated Laboratory of the Department of Agriculture. Some of the parameters studied were soil pH determined by a pH meter, N-total was determined by the Kjeldahl method, P-total was determined using the Olsen method, C-organic was determined by the Walkley and black methods. The results of the analysis showed that the chemical content of the soil on the Gondangmanis guava media showed that the soil pH was neutral – alkaline, the C-organic content was very low, the N-total was very low, and the P-total was very high.

Abstract

Diseases that often attack plants are diseases caused by fungal pathogens causing stress such as fusarium wilt disease caused by Fusarium oxysporum, Alternaria solani, Rhizoctonia solani and Sclerotium rolfsii. One alternative to reduce these pathogens is Trichoderma harzianum. This study aims to determine the potential antibiosis antagonist characteristics of the fungus Trichoderma harzianum against several disease-causing pathogens in plants and the class of compounds contained therein.The method used in this research is experimental and descriptive. Experimental research was conducted by testing the fungus Trichoderma harzianum against several pathogenic fungi as an antibiosis. Then proceed to test the class of compounds using a phytochemical test on the filtrate of the secondary metabolites of Trichoderma harzianum. The results of the potential antibiosis antagonist test on the fungus Trichoderma harzianum showed the results of the antibiosis against the pathogenic fungi Fusarium oxysporum and the fungus Alternaria solani, but on the fungus Rhizoctonia solani and the fungus Sclerotium rolfsii, the results showed the presence of potential antibiosis followed by competition and parasitism. Inhibition on the seventh day of observation showed results of 79% against Fusarium oxysporum, 69% against Sclerotium rolfsii, 61% against Alternaria solani, and 59% against Rhizoctonia solani. Furthermore, for the phytochemical test, the filtrate of Trichoderma harzianum fungus showed positive content of alkaloids, flavonoids, steroids, and saponins.

Abstract

Biological control agents using antagonistic fungi have the ability to inhibit the development of disease-causing pathogens by various mechanisms such as competition for space and nutrients, antibiosis by producing antibiotics in the form of chemical compounds, and parasitism by entangling pathogenic hyphae. Antibiotic mechanism is a condition in which an organism secretes one or more metabolites that have a negative effect on other organisms. One of the fungi that has the ability as an antibiosis is Trichoderma viride, where this fungus secretes secondary metabolites in the form of a viridiol phytotoxin compound. This study conducted to determine the antagonist mechanism of the fungus T. viride in suppressing the growth of Alternaria solani, Fusarium oxysporum, Rhizoctonia solani, and Sclerotium rolfsii which causes disease in some cultivated plants, as well as what compounds T. viride possesses in suppressing the growth of other pathogens. This research was carried out at the Plant Disease Laboratory, Department of Plant Pest and Disease, Faculty of Agriculture, Brawijaya University from November 2020 to August 2021. The research was conducted using Trichoderma viride as antagonist fungus and Alternaria solani, Fusarium oxysporum, Rhizoctonia solani, and Sclerotium rolfsii as pathogenic fungi. This research consisted of 3 stages, the first stage was rejuvenation and macroscopic and microscopic characterization of pathogenic fungi and antagonist fungi. The second stage is the in vitro antagonist test using the dual culture method using a completely randomized design with 6 replications. The third stage is the phytochemical test of secondary metabolites using 5 test, namely terpenoid and steroid test, the alkaloid test, the flavonoids test, the tannin test, and the saponin test. The results showed that T. viride had an inhibitory ability >50% against four types of pathogens. The mechanism of T. viride antagonist against four treatments, three treatments belonged to the competition mechanism and one treatment belonged to the microparasite mechanism. The content of secondary metabolites of T. viride are steroids and alkaloids.

Abstract

Test of three types of growth media Trichoderma sp. and the effectiveness of antagonists against Fusarium sp. in vitro. Trichoderma sp. is a fungus that is found in almost all types of soil and is one type of fungus that can be used as a biological agent to control plant pathogens. Fungal growth is generally strongly influenced by a number of factors including temperature, light, air, pH and nutrients such as carbon and nitrogen such as PDA, bran and banana peels. This study aims to obtain effective conidia that meet the requirements as biological agents, and the media is easy to obtain and the price is relatively cheap. The results showed that the most effective medium was PDA media, namely the number of spores (6.7 x 108), viability (90.66%) and inhibition reached (68.11%), but relatively expensive. While the bran media showed results below PDA media, namely the number of spores (4.8 x 108), viability / germination (89.33%), and the antagonism test of Trichoderma sp. against Fusarium sp. The results of propagation on bran media had an inhibitory power of up to (62.22%) so that the media could be used as an alternative as a substitute medium. Furthermore, the number of banana peel media spores (2.58 x 108), viability (85.33%) and inhibition (61.48%). Key Word : Effectiveness, Medium , Trichoderma sp, Fusarium sp, Antagonism. PENDAHULUAN
