Abstract

Rust Disease Epidemiology of Maize (Zea mays L.) in South Denpasar. Rustdiseases consists of Southern rust, Common rust, and Tropical rust, has contracted causingsubstantial losses in maize in the world. Disease began to be seen attacking the corn crop inSouth Denpasar. The purpose of this study to determine the presence of rust disease on corn ,contracted diseases, epidemiology, and weather factors that dominate affect diseaseprogression. Place of research conducted in South Denpasar, the time from April to June2016. The study used survey methods at the center of the corn crop, and then determine thesample of plants by taking a random 20 corn plants in each plot, which was repeated 3 times.The results showed that the type of rust that attacks corn planting area in the south ofDenpasar was a kind of Southern Corn Rust, caused by the fungus Puccinia polysora.Pathogens can be identified by urediniosporanya, which is elliptical, there is also a round withno makrokopis symptoms on the leaves are brown reddish yellow . Epidemiology of diseasesincluded in the criteria being the epidemic range from 0.054 to 0.329 per unit per day. Therelationship between temperature and humidity with the intensity of the disease were notsignificantly different, but the relationship temperature with infection rate was significantlydifferent, while relationship humidity with infection rate was significantly different. Multipleregression temperature and humidity with infection rate was highly significant.

Abstract

Diveristy and Inhibition of Air-Borne Spores That Contaminate Substrat of OysterMushroom (Pleurotus ostreatus (Jacq. Ex Fr) Kummer). The aim of research to know thediversity, prevalence and inhibition of air-borne spores that could potentially contaminatesubtsrat baglog of oyster mushrooms. In this study using the method: (1) the arrest of sporescarried out during the hours of 7 am to 13 pm by placing three petri dish that already containsmedia PDA 3 pieces, and repeated 3 times, (2) inhibition ability of air-borne spores againstoyster mushroom. The place and time of the study conducted at Jl. Siulan Gang Zella No. 7Denpasar, and implemented in October 2014 to February 2015. The results showed that 13genera, including Aspergillus spp, as many as 10 with a prevalence of 13.51%, Aspergillusniger 7 (9.45%), Brachysporium sp., 1 (1.35%) , Cunninghamella sp. 1 (1.35 %), Fusariumspp. as many as 19 (25.6 %), Giotrichum sp. 1 (1.35%), Mucor spp. , a total of 18 (24.32%),Neurospora spp., as many as 8 (10.81%), Penicillium spp. 2 (2.70%), Phytophthora spp. 4(5.40%), Stachybotrys sp. 1 (1.35%), Trichoderma sp. 1 (1.35%) and Umbelopsis sp. 1 (1.35%). The highest prevalence achieved by Fusarium spp . amounting to 25.67 %, followed byMucor spp. 24.32%. Diversity index (H') was obtained from each replicate of 0.6438, 0.7048,0.5611 with a 0.6366 average. Dominance index (C) obtained by 0.6331. 0.8646, 0.6146, andaverage 0.7041. Diversity including < 1, marked by low diversity and dominance index closeto 1, meaning there is dominance. The dominance held by Fusarium spp . and Mucor spp.Inhibitory effects of air -borne fungi on the growth Oyster mushroom in vitro; The highestachieved by Fusarium spp, with inhibition of 94.00 ± 1.2%, followed by Aspergillus spp.amounting to 92.15 ± 1.5%, and the lowest was achieved by Penicillium spp . amounting to70.37 ± 2.5%.

Abstract

Status of wilt disease in pepper (Capsicum frutescens L.) at Banjarangkan, Klungkung. Wilt disease in pepper , has led to a total yield loss in Banjarangkan, Klungkung regency. Until now the disease was still a threat to farmers in the area pepper. The purpose of research to study the disease includes symptoms, causes disease, the percentage of the disease and the rate of infection (r). Research using existing observations of the disease in three plots of local farmers. Each plot the observed number of diseased plants and entire plants. Samples of diseased plants put in a plastic bag, then placed in an ice box , to be observed macroscopically in the laboratory. The study was conducted in two places, namely surveys Banjarangkan disease in Klungkung , and isolation of the pathogen as well as pathogenicity test carried out in the Laboratory of Plant Pathology, Faculty of Agriculture, Udayana University, Jl. PB Sudirman Denpasar-Bali. The research was conducted from June to November 2013. The results showed that the pathogen that causes wilt disease in pepper at Banjarangkan, Klungkung regency was the fungus Fusarium oxysporum f.sp. capsici, with the disease incidence was 76.67%. Fusarium wilt disease epidemic in pepper indicated by the rate of infection, first gained 0.44 per unit per day, then decreases with time, 0.23, 0.12 and 0.11 per unit per day respectively. The rate of infection ranged from 0.11 to 0.44 per unit per day, this means that the moderate criteria.
