Bacterial leaf blight can cause rice loss between 15-80%. Biorational pesticides can be an alternative to controlling the disease. Bacillus firmus, Burkholderia sp, and Serratia marcescens against bacterial leaf blight on rice plants in the field. The study was conducted in Maret-Juni 2014 in the land of the Independent Farmers Group, Cipeuyeum Village, Haurwangi District, Cianjur Regency, West Java. The design uses a randomized complete block design (RCBD) with 6 treatments and 4 replications. The treatments consist of: 1) Mekongga + biorational, 2) Inpari 14 + biorational, 3) Sintanur + biorasional, 4) Mekongga + without biorational, 5) Inpari 14 + without biorational, and 6) Sintanur + without biorational. The results of the study showed that the application of biorational pesticides can reduce the intensity of bacterial leaf blight disease. Sintanur varieties with the application of biorational pesticides produce higher and higher R / C ratios of 6.81 tons ha-1 and 2.79.

ABSTRACTInduced resistance to bacterial leaf blight disease in rice field by indigenous rhizobacteria.  Bacterial leaf blight is the most important disease on paddy at Southeast Sulawesi. Utilization of biological agents that induce plant resistance is an alternative tool to control bacterial leaf blight disease on paddy. The aim of  the experiment was obtain rhizobacteria that were able to stimulate the growth of paddy plants as well induce plant resistance towards bacterial leaf blight in the field. All experiment units were arranged with a factorial design in a randomized complete block design. The first factor was the rhizobacteria isolates, consisting 4 treatments, i.e: without rhizobacteria (R0), isolate P11a (R1), isolate PKLK5 (IR2), and  mixture P11a and PKLK5 (R3), the second factor is paddy varieties, (V1): IR64 variety, (V2): Cisantana variety. The pathogen was inoculated on leaf when 45 day after crop.  Weekly observation of disease severity, vegetative plant growth (leaf and stem numbers), and yield were conducted. The results showed that the 10 isolates of rhizobacteria tested were able to induce plant resistance toward bacterial leaf blight, stimulated vegetative growth as well as increased yield of paddy plant. Rhizobacteria application could increase the resistance of paddy toward Xanthomonas oryzae pv. oryzae. The application rhizobacteria could increase the vegetative plant growth, application  mixture P11a and PKLK5 isolates showed higher resistance than single application in terms of plant growth and yield, both IR64 and Cisantana varietes

ABSTRACT<br /><br />Hybrid rice varieties  is an alternative technology to improve  productivity of low land rice. The results of previous studies have identified and found the male sterile lines Wild Abortive type and Kalinga are resistant to bacterial leaf blight pathotype III, IV and VIII. The objectives of the research were to obtain information on agronomic characters, yield evaluation, genetic parameters, and repeatability information. The experiment was conducted in two locations namely  Muara and Indramayu experimental stations. The design used was a Randomized Complete Block Design with three replication at each site.  Each replicate consisted of 17 hybrid rice and three check varieties. The results from locations showed that genotype BI485A/BP1 (IR53942) has the highest yield of 5.8 ton ha-1. The coefficient of genetic and phenotypic diversity of six agronomic characters was low. The repeatability for seven character observed were low, except for days to flowering. The  scoring value  of bacterial leaf blight disease in Indramayu showed that nine genotypes exhibit resistance.<br /><br />Keywords: cytoplasmic male sterile lines, disease resistance <br /><br />

Physical Attributes

Hybrid rice technology is one of the promising, sustainable, and proven technologies for increasing rice production and productivity with a yield advantage of 15–30% over modern inbred varieties. The potential of hybrid rice has so far not been exploited in Ghana. This study was undertaken to evaluate the yield potential, reaction to diseases, and physical grain attributes of some introduced hybrids. The trials were laid out in a randomized complete block design (RCBD) with three replicates across three locations. Data were taken on grain yield, yield components, reaction to diseases, and grain physical characteristics. Four promising hybrids (SWARNA 2, ARGH 1501, ARGH 1502, and ARGH 1503) with a mean yield advantage of 15–20.8% over the best inbred check “AgraRice” were identified. With few exceptions, the hybrids were broadly adapted and had adequate resistance to blast and bacterial leaf blight. Most of the test hybrids had long slender grains which make them acceptable to the Ghanaian market but lacked aroma.

This study was aimed at determining the effectiveness of pheromone traps for controlling yellow paddy stem borer (Scabpophaga. Incertulas) insects and testing the effectiveness of biocontrol agents consisting of a mixture of endophytic bacterial cultures (Bacillus firmus E65 and Burkholderia sp E76) and insect pathogens (Serratia marcescens, SKM) based on kaolin bioformulation to control HDB disease. Tests were carried out on the conditions of farmers’ organic land in Cianjur, West Java by installing pheromones to catch male insects in the experimental plots, and applying kaolin-based biopesticide formulations (2.5 g / L). The results show that the application of pheromone traps by using 100 traps in an area of 10 ha, caused the population of male insects to be caught to decrease by less than 40 moths per month. It also effects stem borers to decrease into zero infestations, while stem borer infestation in plots that are not applied to pheromones show <10% infestation. The effect of bioformulation on non-Sintanur cultivars on other minor pests also decrease compared to controls (cv. Sintanur). Kaolin-based bioformulation shows a decrease in bacterial leaf blight of about 84.7% compared to untreated (without bioformulation) plots.APLIKASI PESTISIDA BIORASIONAL TERHADAP PENGGEREK BATANG DAN HAWAR DAUN BAKTERI PADIPenelitian ini bertujuan untuk mempelajari efektivitas perangkap feromon untuk mengendalikan serangga penggerek batang padi kuning (PBPK) (Scirpophaga. incertulas) dan menguji efektifitas agen biokontrol yang terdiri atas campuran kultur bakteri endofitik (Bacillus firmus E65 and Burkholderia sp E76) dan patogen serangga (Serratia marcescens, SKM) berbasis bioformulasi kaolin untuk mengendalikan penyakit HDB. Pengujian dilakukan pada kondisi lahan organik petani di Cianjur Jawa Barat dengan cara memasang feromon untuk menangkap serangga jantan pada petak percobaan, dan melakukan aplikasi formulasi biopestisida berbasis kaolin (2,5 g/L). Hasil penelitian menunjukkan bahwa aplikasi perangkap feromon dengan mengguna-kan 100 perangkap pada area seluas 10 Ha, menyebabkan populasi serangga jantan yang tertangkap menurun kurang dari 40 ngengat per bulan, dan serangan hama penggerek batang juga menurun menjadi nol infestasi, sementara serangan hama penggerek batang pada petak yang tidak diaplikasi feromon menunjukkan <10% infestasi. Pengaruh bioformulasi pada kultivar non-Sintanur terhadap hama minor lainnya juga menurun dibandingkan dengan kontrol (cv. Sintanur). Bioformulasi berbasis kaolin menunjukkan penurunan penyakit hawar daun bakteri sekitar 84,7% dibandingkan dengan petak tanpa perlakuan (tanpa bioformulasi).

Management Approaches

Compost tea, streptomycin and cupravit were evaluated against the Bacterial Leaf Blight diseases of rice cv. BR11 in two management approaches (preventive and curative) under field condition. The selected cultivar BR11 was cultivated in the field laboratory of the Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh, Bangladesh during the period from July to December 2012. The field experiment was carried out with seven treatments in Randomized Complete Block Design (RCBD) and each was replicated thrice. The treatments were T0 = Control, T1= Compost tea as foliar spray 2 times (preventive) @ 1:5 w/v, T2= Compost tea as foliar spray 2 times (Curative) @ 1:5 w/v, T3 = Streptomycin as foliar spray 2 times (preventive) @1gm/10 L, T4 = Streptomycin as foliar spray 2 times (Curative) @ 1gm/10 L, T5 = Cupravit as foliar spray 2 times (preventive) @ 0.2%, T6 = Cupravit as foliar spray 2 times (Curative) @ 0.2%. Cupravit as foliar spray 2 times (Curative) @ 0.2% showed marked effect in reducing Bacterial Leaf Blight diseases of BR11 rice as well as enhancing yield and yield contributing characters. The effect of compost tea also produced similar effects on disease and yield of rice over control. Among the application options of different treatment, curative application provided better results than preventive under field condition.Bangladesh J. Agril. Res. 42(3): 447-456, September 2017
