Sheath Rot

Sheath rot disease caused by Sarocladium oryzae is an important disease on rice. The pathogen that infects uppermost leaf sheath enclosing to the young panicles can cause yield losses up to 85%. Though the disease is commonly controlled using synthetic fungicides, the use of natural products that safer to the environment have been enormously explored. The research aimed to test growth inhibition of S. oryzae colony using methanol leaf extract of binahong (Anredera cordifolia). The research was carried out from June until December 2017 at the Laboratory of Biotechnology Plant Protection, Department of Plant Pest and Diseases, Faculty of Agriculture, Universitas Padjadjaran. The method used was Randomized Complete Design consisted of six treatments and four replications. The treatments were five concentrations of binahong leaf extract of 0.125%, 0.25%, 0.5%, 1%, 2% and one control treatment. The result showed that binahong leaf extract did not inhibit the growth of S. oryzae. The highest inhibition percentage of 4.55% at 0.25% concentration was considered to be a low inhibition category. Although the colony growth of S. oryzae was not significantly inhibited, the extract caused hyphal abnormalities. This actually shows the antifungal potency of the binahong leaf extract that needed further examination with more adequate methods.Keywords : Anredera cordifolia, botanical pesticide, rice sheath rot

The experiment was conducted during 2002-03 in the infested plot of the BINA sub-station at Ishurdi, Pabna to evaluate the effectiveness of Rhizobium strains and biofertilizers in controlling the foot and root rot disease, and to increase green pod yield of Bush bean under field condition. The highest germination (91.6%) was recorded with BINAR P36, which was statistically similar to BAUR 107, BARIR 7029, BARIR 1000, BINAR P6 and BINA biofertilizer. The lowest germination (77.9%) was found in untreated control. The highest foot and root rot (24.5%) was observed in untreated control and the lowest (10.00%) was in BINAR P36. Biofertilizers and Rhizobial strains decreased foot and root rot upto 59.2% over untreated control. The highest green pod yield (20.8 tlha) was obtained for using BINAR P36, which was followed by BARIR 7029, BARIR 892, BARIR 1000, BINAR P6 and BINA biofertilizer. The lowest green pod yield (13.6 tlha) was found in untreated control. Rhizobium strain BINAR P36 may be used as seed treatment for controlling foot and root rot and increasing green pod yield of Bush bean.

Twenty samples of rough rice (Oryza sativa) (unpolished kernels) collected during the 1995 harvest season from Arkansas (seven samples) and Texas (13 samples) were obtained from rice fields known to include plants with symptoms of Fusarium sheath rot putatively caused by Fusarium proliferatum. Samples were analyzed for fumonisin B1 (FB1) at three laboratories using three different extracting solvents by high-performance liquid chromatography (HPLC) or enzyme-linked immunosorbent assay (ELISA) methods. Forty percent of the samples were positive for FB1 at levels ≤4.3 μg/g by HPLC. The same samples contained FB1 at ≤3.6 μg/g when measured by an ELISA method. Most samples that were positive for FB1 were positive for fumonisin B2 (FB2) and fumonisin B3 (FB3) by HPLC at levels ≤1.2 μg/g. Very good agreement was obtained among the two laboratories using HPLC methods and the third using ELISA. Shelling of the unpolished rice results in hull and brown rice fractions. In a sample that contained 4.3 μg/g in whole kernels, the fumonisin level was very high in hulls (≤16.8 μg/g) and low in brown rice (≤0.9 μg/g). Milling of brown rice results in bran and white rice fractions. Fumonisins were found in bran at a level of ≤3.7 μg/g but were below the level of detection by HPLC in white rice. The presence of fumonisins (FB1, FB2, and FB3) was confirmed by fast atom bombardment/mass spectrometry. This is the first report of fumonisins in naturally contaminated rice in the United States.
