Rice is one commodity that have an important value for Indonesian people food. But the production of rice plant decreased by attacking of insect and bacterial. The bacterialleaf blight caused by Xanthomonas oryzaepv.oryzae. To avoid the bacterial leaf blight could used Trichoderma sp. suspension to induced resistant in rice plant. This research was conducted at the Laboratory of Plant Disease and Greenhouse of Lampung University. This study was conducted from June 2016 to August 2016.The experiment was conducted in a complete randomized design arranged with two factors, namely varieties of rice and kind isolate of Trichoderma sp.. The results of this study showed that the application of Trichoderma sp. reducing the severity of bacterial leaf blight diseaseand the kind isolate of Trichoderma sp. can increase the length rootand height of rice plant.

Bacterial leaf blight disease caused by Pantoea ananatis has been reported affects some species of Allium spp. Here, we determined the species of Allium spp. that are not the hosts of the P.ananatis through a host range test. The study designed as a completely randomized design with five replications. Pathogenic bacteria of P. ananatis inoculated to shallot, onion, spring onion, garlic, chives, leek, and cung spring onion in the greenhouse of the Faculty of Agriculture Tadulako University. The incubation period and symptoms of after inoculated by P. ananatis then observed. The results showed that four llium species (onion, onion, scallion, and garlic) were hosts of                P. ananatis while the other three species (chives, leek, and cung spring onion) were not hosts of          P. ananatis.

Fruit rot disease is very damaging to cacao pods, which is caused by Phytoptora palmivora. The attack rate of P. palmivora varies. In Java, losses due to this disease reduce yields by 90 %. P. palmivora is a soil–borne pathogen. It is currently included in the Kingdom Chromista. Control with fungicides is not successful at this time, the alternatives is biologis control with Trichoderma sp. This research used a Completely Randomized Design (CRD) which was arranged in factorial with two factors. The first factor was Trichoderma sp. the second factor was P. palmivora. All treatment combinations were repeated three times. Trichoderma sp. antagonist test to P. palmivora was analyzed using Analysis of Variance (ANOVA) and then further tested using a 5 % BNJ. Trichoderma sp. origin from Jember and Trenggalek districts, East Java, Indonesia were able to act as antagonists against P. palmivora with the highest inhibitory of 78 %. In comparison, the lowest inhibitory was 70 % of isolates from Jember district, East java, Indoe. Characteristics of Trichoderma sp. The origin of Trenggalek Regency and Jember Regency, East Java, Indonesia in inhibiting the growth of P. palmivora has the same species, namely Trichoderma harzianum.

The existence of Xanthomonas oryzae pv. oryzae, the bacteria which causes Bacterial Leaf Blight of rice, is really necessary for the laboratory to support the research activities of the phytopathology experts. Long-term preservation by using glycerol under -20°C can be conducted to preserve the culture’s availability to stay viable in the laboratory. This research aimed to determine the glycerol concentration that is able to preserve the viability and pathogenicity of Xanthomonas oryzae pv. oryzae bacteria after being preserved for 3 and 6 months. This experiments were performed using Completely Randomized Design which comprised of six treatments and four replications, they were: glycerol 50%, 40%, 30%, 20%, 10%, and control (without glycerol). The results of this study showed that viability of Xanthomonas oryzae pv. oryzae that was preserved within 20% glycerol solution for 6 months was different compared to control group. The number of Xanthomonas oryzae pv. oryzae bacteria on 20% glycerol was 4,49 x 109 CFU/ml, while on control group was 1,76 x 109 CFU/ml. 20% glycerol concentration had significant effect on the Bacterial Leaf Blight symptoms’ length after 6-months preservation that observed on the 7th day after incubation. The Bacterial Leaf Blight symptoms’ length on 20% glycerol treatment group was 46,2 mm and 22,7 mm on control group. Meanwhile for the 3 months preservation, the administration of glycerol did not show any significant effect on the Xanthomonas oryzae pv. oryzae’s viability and the Bacterial Leaf Blight symptoms’ length.
