Potato cyst nematode (Globodera rostochiensis Woll.) is an important plant pathogen on potatoes. The development of this nematode in soil could be controlled by using soil fungi. In vitro assay to determine the capacity of soil fungi Fusarium oxysporum TR1, F. solani TR2, F. oxysporum KT1, F. chlamydosporum KT2, F. oxysporum SM1, Paecilomyces lilacinus SM3, and F. chlamydosporum SM4 to parasite G. rostochiensis has been cariied out. The results showed that all of tested fungal species enable to reduce the number of living J2 out from the cyst. The highest J2 reduction, 67.48%, was evidence by using P. lilacinus.

Potatos cyst nematode (Globodera rostochiensis Woll.) in Indonesia has been find for the first time in Malang EastJava. This nematode suppress potato growth and caused yield looses up to 70.63%. Examination the ability of soilfungus Fusarium oxysporum TR1, F. solani TR2, F. oxysporum KT1, F. chlamydosporum KT2, F. oxysporum SM1,Paecilomyces lilacinus SM3, and F. chlamydosporum SM4 dalam pengendalian G. rostochiensis againsit G.rostochiensis on susceptible potato has been carried in out the green house, using Randomized Block Design withfour replication. Results showed that all of the seven fungi had the capacity to parasite G. rostochiensis. Inoculationof P. lilacinus SM3, F. chlamydosporum SM4, F. oxysporum KT1, and F. oxysporum SM1 decreased female populationto 58.56%, 59.09%, 60.76%, and 61.01% respectively compared to that without inoculation. While the other fungionly decrease female population up to 50%. The impact of male population reduction was the enhancement oftuber weight of potato. Adult male nematode was not found in this experiment.

Potato cyst nematode (PCN) is known as organism that could suppress the growth of potatoes and it has been found in West Java. Controlling of PCN by the use of chemical agents has been reduced, hence the use of biological agents such as soil fungi is one of the alternatives. Arbuscular mycorrhizal fungi (AMF) has a potential to be used as a controlling agents. However, the information about it?s effect on nematode, especially in Indonesia is limited. The objectives of this study were to isolate the indigenous AMF from potatoes plantation in a high land at Pangalengan district, West Java, to be used as an agents for controlling nematodes. AMF isolates were cultured and propagated to be used in the test of AMF effectiveness in controlling PCN in a glasshouse. Results showed that AMF at the rate of 150 spores/pot reduced the PCN parameters in term of numbers of juveniles II, fe-males and cysts. The mechanisms of AMF in reducing PCN activities was more likely because of the pro-duction of antifungi isoflavonoid that increased as increasing the rate of AMF spores. The experiment in general showed the successful results in explaining the potential use of AMF as bio-control agents of PCN. Keywords: Arbuscular Mycorrhizal Fungi, Potato Cyst Nematode

Phytophthora sp. is one species of fungus that attacks the seeds of the cocoa plant. Control may use biological agents and Bokashi. This study aimed to determine the effect of Trichoderma sp. and Bokashi on the growth of plants and pathogens Phytophthora sp on cocoa plant in nurseries. The treatment was Trichoderma sp at a doses that was 0 gram, 25 grams, 50 grams and 75 grams, and Bokashi at a doses of 0 gram, 25 grams, 37.5 grams and 50 grams. The study was designed using a completely randomized design with three replications. The results showed that administration of Trichoderma sp. and Bokashi jointly improve the interaction effects canopy height, canopy fresh weight and shoot dry weight, and suppress the intensity of the disease. A dose of 75 grams of Trichoderma sp + 50 grams Bokashi is best dose increase canopy height, canopy fresh weight and shoot dry weight. A dose of 50 grams Bokashi without giving Trichoderma sp. can reduce the disease intensity to 14.95%, and a dose of 25 grams of Trichoderma sp, with or without the provision of Bokashi can reduce the disease intensity to 0%.

Contamination of heavy metal including Arsenic (As) due to mining activities decreased ecosystem quality. The objective of this study was to determine the arsenic level of tailing and agricultural soil, and evaluate the spatial distribution of As in closed gold mine and nearby agricultural area in Buru Sub-district of Maluku. Tailing and soil samples were taken by purposive method based on mining and agricultural activities. Arsenic level in tailing and soil samples was determined by Atomic Adsorption Spectrophotometer after mixed acid extraction. The study showed that gold mine increased As level in the top soil and tailing but soil of nearby agricultural area was not contaminated by As. Increased concentration of As in tailings has been verified. pH level of the agricultural area was neutral hence lowered As availability for plant.

Globodera rostochiensis (Woll) adalah nematoda sista kuning (NSK) pengganggu tanaman yang berbahaya pada tanaman kentang baik di daerah tropis maupun sub tropis. Mekanisme NSK untuk menyebabkan penyakit adalah pembentukan sinsitium yang menghambat serapan unsur hara dari tanah oleh akar tanaman. Penelitian rumah kaca ini dilakukan untuk menguji kemampuan jamur parasitik NSK dalam meningkatkan pertumbuhan dan serapan unsur hara makro fosfor (P) dan kalium (K) tanaman kentang yang ditanam di tanah diinfestasi sista NSK. Percobaan rumah kaca dirancang dalam Rancangan Acak Kelompok yang menguji tujuh spesies jamur antagonis yang diisolasi dari sista NSK. Hasil percobaan menunjukkan bahwa inokulasi Fusarium oxysporum TR1, F. solani TR2, F. oxysporum KT1, F. chlamydosporum KT2, F. oxysporum SM1, Phaecilomyces lilacinus SM3 dan F. chlamydosporum SM4 pada media tanam yang terinfestasi sista G. rostochiensis, dengan nyata meningkatkan bobot kering tajuk serta serapan P dan K pada daun kentang. Jamur antagonis ini berpotensi untuk digunakan sebagai agen hayati pengendali NSK.

Penyakit Damping Off dan hawar daun merupakan penyakit yang sering ditemukan pada tanaman sawi (Brassica rapa) dan tanaman hortikultura sayuran lainnya. Kedua penyakit ini disebabkan oleh jamur Rizoctonia solani. Penggunaan bahan alam berbasis agens hayati mikroba merupakan solusi penanganan penyakit tanaman yang ramah lingkungan dan berkelanjutan, selain untuk pengendalian penyakit juga berpotensi meningkatkan hasil tanaman. Penelitian ini bertujuan untuk mengetahui efek aplikasi agens hayati dari perakaran bambu dan rumput gajah terhadap serangan penyakit hawar daun dan hasil tanaman sawi. Perlakuan yang dicobakan adalah agens hayati dari ekstrak akar bambu (EAB) dan akar rumput gajah (EARG), dan pupuk hayati konsorsium (PHK) dengan konsentrasi : PHK 1% , EAB 1%, EAB 1,5% , EAB 2%, EARG 1% , EARG 1,5%, EARG 2%, dan tanpa agens hayati sebagai kontrol. Percobaan dirancang menggunakan rancangan acak kelompok dengan tiga ulangan. Hasil penelitian adalah pemberian agens hayati dari EAB, EARG dan PHK dapat mengendalikan penyakit hawar daun, dan meningkatkan tinggi tanaman, bobot segar tanaman dan bobot kering tanaman. Agens hayati dengan konsentrasi terbaik adalah PHK 1%, EAB 2% dan EARG 2%. Hasil penelitian yang terbaik dapat direkomendasikan kepada petani untuk meningkatkan produksi tanaman sawi. ABSTRACT Damping off and leaf blight diseases are often found in mustard (Brassica rapa) and other vegetable horticultural crops. Both diseases are caused by a fungal pathogen Rizoctonia solani. The use of natural materials based on biological agents is a sustainable environmentally friendly solutions, besides controlling crop diseases, it also has the potential to increase crop yields. This study aims to determine the effect of application of biological agents from bamboo roots and elephant grass on leaf blight and mustard. The treatments involved biological agents extracted from bamboo roots (EAB) and elephant grass roots (EARG), and consortium bio-fertilizers (PHK) with concentrations of 1% layoff, EAB 1%, EAB 1.5%, EAB 2%, EARG 1%, EARG 1.5%, EARG 2%, and without biological agents as a control. The experimental design was a randomized block design with three replications. The results of the study showed that the the application of biological agents from bamboo roots (EAB), elephant grass roots (EARG) and consortium bio-fertilizers (PHK) can control the leaf blight disease, and can increase the plant height, and the fresh and plant dry weight. The best concentration of biological agents is PHK 1%, EAB 2% and EARG 2%. The best results of this study can be recommended to farmers to increase the production of mustard plants.
