Brassica amendments and summer irrigation for the control of Macrophomina phaseolina and Fusarium oxysporum f. sp. cumini in hot arid region

The combined effect of Brassica amendments (mustard oil–cake or mustard residue at 2.5 tons ha-1) and summer irrigation was tested for survival of Macrophomina phaseolina and Fusarium oxysporum f. sp. cumini and on the severity of dry root rot on clusterbean in the rainy season and on wilt of cumin in the subsequent winter season in the same field. Seed coating with a Bacillus sp., an antagonist bacterium against M. phaseolina, was also integrated with pod residues to improve control of dry root rot. The soil temperature of amended soil after one summer irrigation in June ranged from 38–44°C at 15-cm depth. These temperatures were 0.5–5°C higher than those recorded in unamended soil for the same period and 6–16°C higher when amendments were incorporated in July. A single summer irrigation led to a significant reduction in viable propagules of M. phaseolina, Fusarium oxysporum f. sp. cumini, plant mortality due to dry root rot in clusterbean and incidence of wilt on cumin from Brassica amendments, as compared with the application of amendments in July. A seed coating with Bacillus sp. alone was also effective, but integration with residues did not improve control of dry root rot. In general, amended soil held more soil moisture than unamended soil. These findings have a potential value for irrigated pockets in the hot arid zone of India as well as for many countries with the appropriate climatic conditions

Relative Efficacy of On-Farm Weeds as Soil-Amendement for Managing Dry Root Rot of Clusterbean in an Arid Environment

The effectiveness of certain on-farm weeds as soil amendments was ascertained against Macrophomina phaseolina, a soil-borne pathogen causing dry root rot of crops grown under rainfed conditions in arid regions. Population changes in M. phaseolina were determined in soils amended separately with residues (1%, w:w) of Aerva persica, Celosia argentea, Corchorus depressus, Euphorbia hirta, Heliotropium subulatum and Polycarpaea corymbosa, for a period of 90 days. Significant reductions by 90.4–100% in the population of M. phaseolina were achieved with all the weed residues except P. corymbosa. Celosia and Euphorbia residues completely eradicated viable propagules of M. phaseolina. A strong increase (44–61%) in the population of antagonistic actinomycetes was also found in soil amended with Corchorus and Euphorbia. In field tests, soil amended (50 g m2) with Euphorbia, Aerva and Celosia residues significantly reduced dry root rot incidence on clusterbean and also reduced M. phaseolina propagules in the soil. However, dry root rot incidence in Polycarpaea-amended soil (5.8–24.6%) was not significantly different from that in non-amended soil (4.3–25.3%) in both years of the experiment. P. corymbosa also increased the number of propagules of M. phaseolina in the soil. The results demonstrate that dry root rot of rainfed-cultivated annual crops in arid land can be managed with certain weeds as a soil amendment

Cumin wilt management – a review

Cumin (Cuminum cyminum L.) is one of the oldest seed spice and an important production constraint is wilt caused by Fusarium oxysporum f. sp. cumini Prasad and Patel (Foc) and crop losses could be up to 60%. Maximum population of Foc was estimated at 0-5 cm soil depth in the presence of crop, but the population density tended to decline progressively with distance from the surface. Resting structures of the Foc, the chlamydospores, survive in the soil for more than 10 years. The inoculum density in the soil increases with each year of cumin cultivation and is directly proportional to disease incidence in the field. In this review, an effort has been made to compile research findings generated during past four decades on symptomatology, ecology and management strategies. In the absence of resistant sources against Foc, to reduce population of pathogen below the economic threshold level, integration of cultural, chemical and biological control measures is the only effective way to manage this diesease. &nbsp

“No good man will ever want me”. How structural social inequality increases women’s vulnerability to HIV transmission: a qualitative study from Bandung, Indonesia

Understanding the pathways that expose women to HIV transmission are vital in improving HIV prevention, especially among a “hidden” group of women without pre-established known risk for HIV. We investigated the pathways which place certain women at greater risk for HIV in a qualitative exploratory study with theoretical sampling using an emergent theory study design in an urban setting in Indonesia. We conducted semi-structured interviews with 47 HIV-infected women, one focus group discussion with five young women who occassionally engage in sex work, participant observation at six sex work venues and two midwife clinics, and 11 informal interviews with midwives, nurses, and obstetricians. Our research found that many women not characterized as belonging to a “high-risk group” or “key population” were nevertheless at increased risk for HIV. A history of sexual abuse, premarital sex, divorce, or involvement in sex work, often precipitated by poverty coupled with discriminatory public health policies further heightened women’s exposure to HIV. While reaching at-risk populations is a key strategy in HIV prevention, a novel and more tailored approach is needed to reach more hidden categories of women with less apparent risk behavior yet considerable risk for HIV infection

Non-Adherence in Patients on Peritoneal Dialysis: A Systematic Review

Background: It has been increasingly recognized that non-adherence is an important factor that determines the outcome of peritoneal dialysis (PD) therapy. There is therefore a need to establish the levels of non-adherence to different aspects of the PD regimen (dialysis procedures, medications, and dietary/fluid restrictions). Methods: A systematic review of peer-reviewed literature was performed in PubMed, PsycINFO and CINAHL databases using PRISMA guidelines in May 2013. Publications on non-adherence in PD were selected by two reviewers independently according to predefined inclusion and exclusion criteria. Relevant data on patient characteristics, measures, rates and factors associated with non-adherence were extracted. The quality of studies was also evaluated independently by two reviewers according to a revised version of the Effective Public Health Practice Project assessment tool. Results: The search retrieved 204 studies, of which a total of 25 studies met inclusion criteria. Reported rates of nonadherence varied across studies: 2.6 1353% for dialysis exchanges, 3.9 1385% for medication, and 14.4 1367% for diet/fluid restrictions. Methodological differences in measurement and definition of non-adherence underlie the observed variation. Factors associated with non-adherence that showed a degree of consistency were mostly socio-demographical, such as age, employment status, ethnicity, sex, and time period on PD treatment. Conclusion: Non-adherence to different dimensions of the dialysis regimen appears to be prevalent in PD patients. There is a need for further, high-quality research to explore these factors in more detail, with the aim of informing intervention designs to facilitate adherence in this patient populatio
