Clubroot is very detrimental disease to cabbage production so as farmers work on various efforts to control it. The use of fungicides not only ineffective but also pollute the environment, therefore biological control system need to be pursued. The use of antagonistic agents such as Pseudomonas has been widely studied and known effective in suppressing various pathogens. Therefore it is worth trying its effectiveness against Plasmodiophora brassicae, a pathogen of cabbage. The purpose of this study was to obtain indigenous Pseudomonas which effectively suppress the pathogens and may also increase plant growth. Microbes were isolated from the cabbage area using the Kings'B medium with multilevel dilution. All isolates were tested for their effectiveness in pots in a Completely Randomized Design with a concentration of 1.5x106 CFU (Colony Forming Unit) per pot. The variables observed were plant growth, number of club roots, and percentage of disease incidence. Fourteen isolates of Pseudomonas were isolated. Three Pseudomonas isolates were found most effective at suppressing clubroot disease and increasing plant growth. The best isolate obtained was Pseudomonas-6, followed Pseudomonas-9, and Pseudomonas-8.

The high economic value of cabbage crop leads farmers to make various efforts to suppress the pathogen of club root which is detrimental to plants. Efforts that need to be put forward must be environmentally safe. One way that is environmentally friendly is to control a pathogen biologically using antagonistic microbes. Therefore, the use of microbes such as Trichoderma which has been widely studied is important because it was able to suppress clubroot incidence and stimulate plant growth as well. Meanwhile, the need for plant nutrients to maximize plant growth requires an input of organic materials such as lignohumate which preserve soil nutrients, improve soil structure and increase plant resistance to biotic and abiotic stresses. The previous study on this scheme found an effective indigenous Trichoderma to suppress clubroot, therefore it is used in the current study. The objective of this study was to find out a combination treatment of Trichoderma and lignohumate which can suppress clubroot and increase plant growth. This experiment used a Randomized Block Design with 2 factors and 3 replications. Trichoderma concentration consisted of 3 levels, namely 0 spores (control), 1x106 spores. 2x106 spores, and 3x106 spores per plant which were suspended in 150 ml of water. The lignohumate treatments were 0.01, 0.02, 0.05, 0.1, 0.5, 1.0, and 2%. The results showed that lignohumate treatment was interact with Trichoderma population number on disease incidence, total clubroot, root dry weight, but not to canopy dry weight. The most suitable combination of treatments was the Trichoderma population of 3x106 spores (15 g) in combination to lignohumate of 0.5%. This combination resulted in the lowest disease incidence, the lowest total clubroot, root dry weight, and the highest canopy dry weight. The higher the lignohumate concentration up to 0.5%, the higher the number of microbes (fungi and bacteria) growth, howeverit decreased above the concentration of 0.5%.

Cultivation of organic snake fruit in Bali which is done on dry land with the irrigation depends on rainfall and the fertilization generally only uses uncertain amount of fallen leaves, it reduces the productivity, quality, and continuity of fruit production over time. In rhizosphere of snake fruit there are various types of indigenous endomycorrhiza that potentially can be developed as biofertilizer, but as a biofertilizer, the low number of spores population for inoculum becomes a limiting factor in using indigenous endomycorrhiza. The effort that can be done are to propagate the spores by giving water stress treatment. This study aimed to obtain the best rhizosphere location of snake fruit as the source of spores and the level of soil water content to multiply the spores. The research was conducted in the green House, Farm Station, Agriculture Faculty, Udayana University at Jalan Pulau Moyo, Denpasar, from October 2017 to January 2018. The spore propagation used nested experiment with Randomized Block Design patterns. The treatments were rhizosphere location as the source of indigenous endomycorrhizas spore consists of three levels (Bebandem District Karangasem Regency, Payangan District Gianyar Regency, and Pupuan District Tabanan Regency) and soil water content consists of three levels (100%, 70%, and 40% field capacity). The results of the research showed that the source of indigenous endomychorrizae from snake fruit rhizosphere in Payangan District gave the highest number of spores found and the highest percentage of the spore increase after propagation. While in the soil water content treatments, the highest number of spores found and the percentage of the spore increase after propagation were obtained at soil water content of 40% field capacity. The percentage of root infections from different sources of indigenous endomychorrhizae and different levels of soil water content is same i.e 100%.

PRIMER DESIGN OF CVPDr DNA FRAGMENT SEQUENCES THAT AMPLIFY SPECIFIC FRAGMENTS TO DISTINCT THE RESISTANT FRAGMENT FROM Triphasia trifolia (Burm. F.) P. Wils. AND THE SUSCEPTIBLE FRAGMENT FROM Citrus nobilis Lour. Ni Made Ayuratih Utami; I Gede Putu Wirawan; I Ketut Suada

CVPDr is a DNA fragment that indicates that plants are resistant to CVPD. Previous research using primers that amplified 841 bp CVPDr fragment was able to amplify the fragment from Triphasia trifolia that considers being a resistant plant, Citrus aurantifolia var. seedless which considers being a tolerant plant, and some susceptible citrus plants to CVPD disease. In this study, we designed some primers that amplified only CVPDr DNA fragment from T. trifolia which consider as the resistant plant and a primer that amplified only DNA fragmen from Citrus nobilis which consider as the susceptible citrus plants. The primers for CVPDr on T. trifolia are TCATCTGCATGGGATACC for forward primer and GCCTTGAGCTTGTAAGTG for reverse primer which turned out to amplify the DNA of T. trifolia and also the C. nobilis cultivar Denpasar and only succeeded in not amplifying the C. nobilis cultivar Gianyar. The primers for CVPDr on C. nobilis are GAATGGCTTAGCAGAAAGG for forward primer and GGTTGTAGATGGACATAGG for reverse primer turned out can not only amplify the DNA C. nobilis but also amplify T. trifolia.
