A field experiment was conducted at Regional Research and Technology Transfer Station, OUAT, Chiplima, Sambalpur, Odisha, India for the management of purple blotch of onion. From the experiment it was found that all the treatments were effective to reduce the severity of the disease as compared to untreated control. Among the treatments, seed treated with Carboxin 37.5%+Thiram 37.5%@ 2g/kg and three foliar sprays of Trifloxystrobin + Tebuconazole @0.4g/l of water at 10 days interval starting from initiation of the disease was most effective in reducing the purple blotch disease of onion (69.5% disease control) and was closely followed by seed treated with Carboxin 37.5%+Thiram 37.5% @ 2 g/kg and three foliar sprays of Tebuconazole @ 1.0ml/l of water (62.3% disease control). A maximum increase of yield (83.4%) with highest cost benefit ratio (1.97) was also achieved with the same treatment.

Web blight caused by Rhizoctonia solani causes huge yield loses in urdbean (Vigna mungo). All the commercially grown varieties are susceptible. Hence, more than ten fungicides were evaluated as foliar sprays during kharif season 2005, 2007-2010 using susceptible variety UL 338. Two foliar sprays of fungicides, namely; hexaconazole 5EC (Contaf 5EC)@ 0.1%, difenconazole 25EC (Score 25EC) @ 0.05%, carbendazim 50WP (Bavastin 50WP) @ 0.1% and propiconazole 25EC (Tilt 25EC) @ 0.1% significantly reduced the disease severity resulting in 81.1, 80.6, 65.9 and 76.2% control over unsprayed check with corresponding mean yield of 872, 821, 791 and 754 kg/ha compared with the mean yield of 584 kg /ha in unsprayed control . The net benefit for the two foliar sprays of hexaconazole 5EC, difenconazole 25EC, propiconazole 25EC and carbendazim 50WP and chlorthalonil 50WP, has been worked out to be Rs.10229, 6891, 6375, 4524 and 3274, respectively for the crop grown for the grain purpose (@Rs. 4300/q) with the cost: benefit ratio of 5.8, 3.1, 2.6, 4.0 and 1.8, respectively. In the crop, grown for the breeder seed purpose (Rs.12000/q), the net profit for foliar sprays of hexaconazole 5EC, difenconazole 25EC, propiconazole 25EC, carbendazim 50WP and chlorthanonil was worked out to be Rs.32405, 25140, 17616, 22614 and 16980 respectively with cost: benefit ratio of 16.0, 8.6, 7.3, 11.2 and 4.9, respectively. The same trend was observed for foundation and certified seed also. The fungicides were effective in reducing the severity of powdery mildew also.

Background: YMV disease in mungbean is one of the major disease causing heavy losses annually throughout the country. As the disease is transmitted by insect vector, management of vector is important to check the YMV disease that can minimise the losses. The present investigation was aimed to evaluate different IPM modules for management of YMV disease of mungbean. Methods: Field experiments were carried out during Rabi season of 2016-17 and 2017-18 at the Research Farm of Regional Research and Technology Transfer Station, Chiplima, Sambalpur, Odisha, India. Population of whitefly was recorded on three leaves selected from top, middle and bottom canopy of the plant. Disease severity was recorded by using 0-9 scale. Result: The IPM module i.e. seed treatment with Thiamethoxam 25 WG @ 5 gm kg-1 of seed, installation of yellow sticky trap @ 50 ha-1 and spraying of Acetamiprid 20 SP @ 0.3 gm l-1 of water was found as the most effective among all other modules. Pooled analysis of two years data revealed that 65.5% YMV disease control and 59.3% reduction of white fly population over control were performed by the said IPM module. A maximum increase in yield (84.8%) and highest cost benefit ratio (1.77) were also achieved with the module.

 Bodyweight exercises (also popularly known as calisthenics) is a classic training method and its practice has been widespread since the 19th century, but little evidenced in the scientific literature over the years. This type of training aims to promote multi-system adaptations using body weight as an overload with no or few implements [1–3]. This characteristic makes exercise with body weight easy to apply, in addition to having an excellent cost-benefit ratio when compared to other training possibilities that require machines or materials [4,5].

Abstract Niger (Guizotia abyssinica Cass.) is an important minor oil seed crop grown in dry areas grown mostly by tribal and interior places as life line of tribal segment. Tribal people mainly use its oil for cooking purpose, above than that there were also other uses. Hence, the niger crop should be protected from the infection. The crop is affected by number of fungal diseases. Therefore, a field experiment was formulated for three years with the four replications at the Niger Research Station (NRS) at Navsari Agricultural University (NAU), Vanarasi, Navsari (Gujarat) on the foliar diseases of GN-1 variety of niger crop. In this experiment, six different fungicides along with one control have been evaluated to control the Alternaria and Cercospora leaf spot diseases, out of which all the fungicidal treatments were significantly superior over the control. Here, foliar spray on the incidence of diseases was compared with the control (without any treatment). All the fungicidal treatments were significantly superior over the control to reduce Alternaria and Cercospora leaf spot diseases of Niger crop. Treatment of Carbendazim + Mancozeb (0.2 %) with two sprays first from the initiation of the disease and second after the interval of 15 days recorded the lowest incidence of Alternaria (14.56) and Cercospora (14.94) leaf spot diseases of niger and recorded the highest seed yield 337 seed yield kg/ha along with the net return with cost benefit ratio graph.

To the Editor.— Two recent reviews in Pediatrics1,2 provide much interesting information on the effect of home visits on the health of women and children. However, I was disappointed not to find in either article more than token reference to the cost of the programs reviewed. In this day of increasingly scarce health care resources, we no longer have the luxury of evaluating programs such as these without detailed consideration of their cost-benefit ratio.

AbstractThe authors review the main concepts regarding the importance of cleaning/disinfection of ultrasonography probes, aiming a better comprehension by practitioners and thus enabling strategies to establish a safe practice without compromising the quality of the examination and the operator productivity. In the context of biosafety, it is imperative to assume that contact with blood or body fluids represents a potential source of infection. Thus, in order to implement cleaning/disinfection practice, it is necessary to understand the principles of infection control, to consider the cost/benefit ratio of the measures to be implemented, and most importantly, to comprehend that such measures will not only benefit the health professional and the patient, but the society as a whole.

In this paper we explain some of the difficulties of providing forecasts of the financial benefits of early intervention programmes, focussing on those delivered during the early childhood period. We highlight the diversity of early intervention, and the complexity and multiplicity of outcomes. We summarise recent work at the Early Intervention Foundation to assess the evidence on the impacts of early intervention, recognising the diversity of approaches to delivery and the importance of innovation and local practice as well as of rigorous approaches to evaluating causal effects. We also describe new ways of assessing accurately the local fiscal costs of late intervention and consider the implications of this for addressing the well-established barriers to investment in prevention. Our analysis brings to the fore gaps in the evidence from which even the most rigorous ‘gold-standard’ research is not immune. These limitations prevent the production of an accurate and realistic cost-benefit ratio or net present value for the majority of programmes as delivered in practice. We suggest some paths towards a firmer foundation of evidence and a better alignment of evidence and policy.
