Selection of Rhizosphere Bacterial Isolates and Development of Antagonistic Bacterial-Based Formulation to Control Fusarium Wilt on Shallot

Wilt disease caused by Fusarium spp. is a major disease in shallot-producing areas particularly in the North Coast of West Java. The research was aimed to select rhizosphere bacteria and develop an antagonistic bacterial-based formulation for its effectiveness to suppress wilt disease caused by Fusarium spp. on shallot plant under greenhouse and field trials. The field trials were carried out using randomized complete block design with four replications at the shallot farmer condition in Subang and Indramayu during the 2019 planting season. Antagonistic test of bacterial isolates from the rhizosphere showed that most of the bacterial isolates can be used as a biocontrol to Fusarium spp. pathogen. The result revealed that bacterial suspension formulation (E-76 + DBS-2 isolates) in combination with phytohormone (1:1 [v/v]) at Subang and Indramayu tended to suppress Fusarium wilt disease intensity with the disease inhibition ranging from 73.54–93.39% and 66.3–95.65%, respectively. The spraying application of formulation 2.5 ml/l was obtained as the best formula to suppress the disease. The growth and production of shallot were also affected by the application of antagonistic-bacterial formula.

This research was conducted in Pante Cermin, Padang Tiji Subdistrict, Pidie District. in March to August 2015, with the aim to know the use efficienci of Trichoderma sp on the growth of several types of Banana seedlings (Musa Paracica L.) This research using Randomized Block Design (RAK) factorial pattern with the factors studied is the type of banana and trichoderma dose . Both factors consist of 4 levels: Banana Barangan (J1), Ambon banana (J2), Banana King (J3) and Geupok banana (J4). While the dose of Tricoderma sp is: TO = 0 g / seeds T1 = 15 g / seeds T2 = 30 g / seedlings and T3 = 45 g / seedlings. So there are 16 treatment combinations and repeated 3 times, which resulted in 48 experimental units.To determine the influence of each treatment and its interaction on the growth of banana seedlings, the analysis of variance (Test F) and continued with the test of Beda Nyata Jujur (BNJ) at 5% level.The results showed that the growth of good banana seedlings among 4 species studied was shown by Barangan bananas, but not unlike bananas. However, trichoderma administration until the age of 4 months has not shown the growth and intensity of different attacks. So it should be extended the study period to 6 months. After 6 months of research there has been a difference in growth and intensity of attack, where the intensity of the greatest attack is shown by T0 (without trichoderma). Medium intensity of smallest attack is shown by T3 (Dose trichoderma sp 45 gr / banana seedlings). The type of banana does not affect the growth and intensity of fusarium wilt attack. and the interaction of these two factors had no significant effect on the growth of banana seedlings and the intensity of Fusarium wilt disease.

Eight cotton cultivars, with and without aldicarb treatment, were evaluated for their effect on the severity of the root-knot nematode-Fusarium wilt disease complex in cotton. A randomized complete block design with a split-plot arrangement of treatments was used with cotton cultivars as the main plots and nematicide treatments as the subplots. Results in 1994 and 1995 were similar. Yield of lint, boll weight, and wilt and root-gall ratings were different among cultivars and between nematicide treatments both years. Increased lint yield and boll weight, and reduced root-gall and wilt ratings were associated with application of aldicarb. Increased lint percentage was associated with application of aldicarb in 1994, but not in 1995. Fiber micronaire, elongation, uniformity, and strength were different among cultivars, but not between nematicide treatments. Fiber length (UHM; Upper-Half Mean) was different among cultivars and was higher in the aldicarb-treated plots in both years. Numbers of Meloidogyne incognita second stage juveniles and eggs extracted from soil samples were lower in the aldicarb-treated plots in July, but not at harvest, both years. Population densities of M. incognita were not different among cultivars, except the mid-season sample in 1995.

Uno de los factores que limitan de manera importante la competitividad y sostenibilidad del sector ganadero de la región Caribe es la degradación de suelos y praderas. El objetivo del estudio fue evaluar en fincas del departamento del Atlántico y dedicadas a la de producción de carne, el efecto de las tecnologías de renovación de praderas como la intervención mecánica con labranza vertical, establecimiento de una nueva gramínea, aplicación de un plan de fertilización y pastoreo rotacional, sobre la producción de carne. Se seleccionaron tres fincas en las cuales se estableció una línea base en el año 2007 y posteriormente en los años 2008 y 2009 se evaluó el efecto de la renovación sobre la producción de forraje y carne. Se determinó la disponibilidad de forraje tanto en la pradera renovada como en la pradera sin renovación y cada mes se registró el peso de los animales. Los datos se analizaron empleando un diseño de bloques completos al azar con arreglo factorial. Los resultados mostraron un efecto significativo de la renovación de praderas en la producción de forraje, tanto en época seca como lluviosa (P < 0.05). El efecto fue mayor en la época lluviosa que en la época seca (P < 0.05). Las praderas renovadas tuvieron en promedio 1,5 veces más forraje que la pradera testigo (21,9 vs. 8,9 t de MS ha-1). Durante el período seco, la tecnología de renovación disminuyó el efecto negativo del estrés hídrico, manteniendo una producción promedio de forraje que duplicó la registrada durante el mismo período en la pradera sin intervención (5,2 vs. 2,5 t de MS ha-1). En la producción total de carne también se observó un efecto de renovación de praderas tanto en época seca como lluviosa. El efecto de la tecnología en producción de carne fue mayor en la época de lluvias que en la época seca (353 vs. 163 kg ha-1). El promedio general indicó que la producción de carne por unidad de área fue 4 veces mayor en la pradera renovada que en la pradera testigo (859 vs. 171 kg ha-1).Los resultados mostraron que la aplicación de tecnologías de renovación de praderas a nivel de finca en el departamento del Atlántico se logra aumentos significativos en producción de forraje y producción de carne por unidad de área lo cual tendría repercusiones en los ingresos de los productores. Effect of the renewal technology pasture of Bothriochloa pertusa (L.) A. Camus on meat production in the North Coast of Colombia One of the factors that significantly limits the competitiveness and sustainability of the livestock sector in the Caribbean region is the degradation of soils and pastures. The objective of this study was to assess, on farms engaged in the production of meat in the Atlántico department, the effect of pasture renewal technologies, such as mechanical intervention with vertical tillage, establishment of a new grass, application of a fertilization plan and grazing rotation, on meat production.Three farms were selected in which a baseline was established in 2007 and subsequently, in 2008 and 2009, the effect of the renovation on the production of forage and meat was evaluated. Forage availability was determined in both the renewed and non-renewed pastures; and each month, the weight of the animals was recorded. The data were analyzed using a randomized block design with factorial arrangement. There was a significant effect of the applied technology on pasture production in both the wet season and the dry season (P < 0.05). The effect was greater in the wet season than in the dry season (P < 0.05). The recovered pasture had 1.5 times more forage in comparison with the control pasture (21.9 vs. 8.9 t DM ha-1). In the dry season, the applied technology decreased the detrimental effect of water stress, producing twice the amount of forage than the control pasture in the same period (5.2 vs. 2.5 t DM ha-1). The recovered pasture in the dry and wet seasons also positively affected total beef production. Meat production was higher in the rainy season than during the dry season (353 kg vs. 171 kg ha-1). The overall average indicated that meat production per unit area was 4 times higher in the recovered pasture than in the control pasture (859 kg vs. 171 kg ha-1). The results showed that pasture renewal technologies on farms in the Atlántico department provide significant improvements for forage and meat production per unit area that could have effects on the farmers incomes.
