Abstract

The study entitled Persistence of the virus that causes mosaic disease in chili seeds originating from the production of chili plants that are attacked by a virus that is treated by soaking at some temperature aims to see the persistence or presence of the virus that causes the mosaic. The persistence of the virus is done by observing the chilli seedlings that are 8 weeks after planting. The research was carried out at the Plant Pest and Disease Laboratory, Faculty of Agriculture, Mulawarman University, Samarinda. The study was conducted using the observation method that is directly observing the treatment carried out. This study used 5 treatments and each of 4 replications, consisting of: C1 = treatment of warm water with a temperature of 40 ° C for 10 minutes, C2 = treatment of warm water with a temperature of 45 ° C for 10 minutes, C3 = treatment of warm water with a temperature 50 ° C for 10 minutes, C4 = treatment of warm water with a temperature of 55 ° C for 10 minutes, Cs = treatment of warm water with a temperature of 60 ° C for 10 minutes. The results showed that soaking warm water had an influence on the persistence of viruses carried in the seeds to the development of mosaic disease in chilies. Temperatures of 50 ° C and above have been able to prevent mosaics disease at chillie plant.

Abstract

The research was conducted to determine: endophyte fungi on paddy plant (Oryza sativa); the antagonistic percentageof endophyte fungi against to Pyricularia oryzae Cav.; and the antagonistic mechanisms between each endophyte fungi to Pyricularia oryzae Cav..The experiment was conducted at the Integrated Laboratory of Agriculture Faculty of Mulawarman University, and samples of infected plant was collected from Sungai Kapih village, Sambutan Sub-district of Samarinda City The experimental treatments was arranged in a Completely Randomized Design (CRD), consisting of four treatments and each treatment was repeated ten times.The results showed that endophyte fungi isolated from the paddy plant (Oryza sativa) were Trichoderma sp., Rhizopus sp., Gliocladium sp., and Penicillium sp. The competition was proved as the antagonistic mechanism of Rhizopus sp. against, while antibiosis was proved as the antagonistic mechanism of Penicillium sp. against. Trichoderma sp. and Gliocladium sp. against were shown to have two antagonistic mecanism are competition and parasitsm. The capability of endophyte fungi as a biological agents to compete those P. Oryzae was express an antagonism capacity differences, the highest rate of inhibition was occurred on the P. oryzae vs Gliocladium sp.(78,96%). Keywords :Pyricularia oryza Cav., Endophyte fungi, Antagonistic mechanim
