Abstract

Blast is important disease of rice, and it caused by Pyricularia oryzae Cav. Synthetic fungicide in plant disease control may have negative impacts, so another alternative is needed. Yeast can used as a biocontrol agent. This research aims to investigate the potential of the yeast from leaf phyllosphere of rice paddy as biocontrol agent against P. oryzae. This research was consisted of yeast exploration, isolation and filtrate antagonistic inhibition essay to P. oryzae, and yeast growth respon due to temperature. Ten isolates successfully obtained and tested as antagonist to P. oryzae. Five isolates, YLP05; YLP07; YLP08; YLP09; YLP10, have percentage inhibition more than 30% at 3 dai (day after incubation) dan more than 50% at 7 dai, but their filtrate had not shown any inhibition activity. The five isolates had been formed colony on 1st day at 30 °C. Based on diameter and percentage of forming colony, the optimal temperature is different for each yeast isolates. Four isolates which can still grow at 20-40oC those are YPL05, YLP07, YLP09, and, YLP10.

Abstract

The production of black rice has decreased due to disease attacks. One way to improve rice resistance to disease is through the induction of mutations with gamma ray radiation. The purpose of this study is to evaluate the resistance of black rice induced by Co-60 by 0 Gy, 200 Gy and 300 Gy against disease. The research was conducted on BBI's land in Sungai Kakap Village, Kubu Raya Regency during one planting season, from October 2017 to April 2018. This research used a descriptive research method. Each treatment was observed as many as 50 rice plants, so that the total sample of observation is 150 plants. Observations were made 3 times, during vegetative, maximum vegetative, and generative periods. Disease identification is done in two ways which are macroscopic and microscopic. Assessment of the severity of the disease is guided by the guidebook. The results of the study found 4 diseases that attack black rice mutant plants, namely narrow brown spots, leaf and collar blast disease, fusarium disease, and midrib blight. Narrow brown spot disease, rice irradiated by 200 Gy is the most resistant with medium - rather resistant category. Leaf blast disease, rice that is not irradiated is most resistant with medium - rather resistant category. Panicle blast disease, rice irradiated by 200 Gy is most resistant with medium - resistant category. Keywords: Black rice, Cobalt-60 induction, disease scoring
