Despite the breakdown of Bs2 resistance, yields of the Bs2 hybrids were not reduced. Tolinapant and race of isolates from susceptible, Bs2, and Bs1-2-3 hybrids at the end of the 2018 trial were dependent on source plant genetics. AvrBs2 was expressed in 86% of isolates from a susceptible hybrid, but not in any isolates from the Bs2 and Bs1-2-3 hybrids. HR resistances effectively protected yield, but their deployment may not be sustainable without cultural practices such as crop rotation that limit pathogen survival and transmission to subsequent crops.The cyst nematodes are important plant-parasitic nematodes and make detrimental economic impacts worldwide. Heterodera elachista attacks rice in Japan (Ohshima 1974), Iran (Tanha et al. 2004) and China (Ding et al. 2012) and also attacks corn in Italy (De Luca et al. 2013) and northeast China (Xiao et al. 2019). Considering this nematode can infect these two most important crops with high reproduction rates, special attention should be paid to avoid its spread to new areas by soil, water, and agricultural practices. A survey for cyst nematodes was performed in fields of corn seed for propagation in September 2018 in Zhangye City, Gansu Province, which is the biggest corn seed production base in China. One hundred seventy four samples were collected by the zig-zag method in about 25 ha corn fields. Each soil sample containing approximately 1 kg soil in total was from the mixture of 20 cores (20 cm in depth and 0.2 cm in diameter). Cysts were detected in 6 out of 174 samples using the sieving-decanting method (he morphological and molecular features. Twenty-day-old corn seedling (cv. Tiannuo) was inoculated with 3000 J2 and eggs in a pot filled with sterile soil. Eight plants were inoculated and two uninoculated plants were used as controls. J2 were found in the stained roots at 10 d after inoculation and J4 were detected at 30 d. These inoculated plants exhibited yellowing and dwarfing similar to the symptoms observed initially in the field, and the control grew normally. After 60 d, the average of 28 cysts were detected from each inoculated plant. This is the first report of H. elachista in Gansu Province, northwest China.Tomato (Solanum lycopersicum), pepper (Capsicum annum), and gboma (Solanum macrocarpon) are major vegetables in Togo, with many people depending on these crops for their livelihood. In December 2018, during the dry season with temperatures between 21°C to 35°C, tomato ('Petomech'), pepper ('Gboyebesse') and gboma (local landrace) showing wilt symptoms without foliar yellowing were collected from two locations, Tchouloum and CECO-AGRO sites in the Sotouboua Prefecture of Togo, ~300 km from the capital city of Lome. Disease incidence ranged between 10% to 50% in multiple fields. Cut stems of most wilting tomato, pepper and gboma plants produced bacterial ooze in water and vascular discoloration was visible in longitudinal stem sections. Ground cut stem tissue tested positive with Rs ImmunoStrips specific to the Ralstonia solanacearum species complex (RSSC) (Agdia Inc., Elkhart, IN, USA). Collected samples were stored at ambient temperature and cultured within 36 hr. Culturing sap from cut stems plated on modifie with the Rs ImmunoStrips. This is the first identification of RSSC in Togo. These results will guide development of disease management strategies and regionally appropriate breeding of vegetable lines with resistance to the phylotype I RSSC strains present in Togo.In July 2018, a sample of lavender var. Grosso (Lavandula × intermedia 'Grosso') from Miami County, OH was received by The Ohio State University Vegetable Pathology Laboratory in Wooster. Lavender plants were field-grown in sandy clay soil with plastic mulch under drip irrigation. Disease incidence ranged from 0 to 32% depending on variety. Leaves and stems showed dark necrotic lesions that varied from roughly circular (ca. #link# 0.3 to 0.5 mm diameter) to large coalesced necrotic areas surrounded by a water-soaked halo. Bacterial streaming from lesions was observed microscopically. Leaf tissue pieces (~0.5 cm2) were surface sterilized in 70% ethanol for 30 seconds and rinsed in sterile deionized water. The tissue was sliced aseptically into smaller sections in 100 μl sterile water and the bacterial suspension was streaked on yeast dextrose calcium carbonate agar medium. Ten yellow Xanthomonas-like colonies were selected after 72 hours of incubation at 28ºC in the dark. Strains were gram negative, oxidase negative ported on ornamental plants (Mirik et al. 2010, Oliver et al. 2012, Roberts and Parkinson 2014, Klass et al. 2019), however additional research is needed to establish the host specificity of lavender strains. To our knowledge this is the first report of X. hortorum causing bacterial leaf spot of lavender in Ohio. The disease may negatively impact the yield and quality of flowers used in production of lavender oils and essences.

To understand the financial impact of health system adoption of novel heart failure medications under US alternative payment models (APMs).

This study used a decision tree model to assess the financial impact of health system adoption of sacubitril/valsartan to treat acute decompensated heart failure (ADHF). A comparator scenario modeled current health care utilization and cost for treating hospitalized ADHF patients with angiotensin-converting-enzyme inhibitors (ACEi) or angiotensin-receptor blockers (ARB). The study then measured the impact of adopting sacubitril/valsartan to treat ADHF on health system economic outcomes. Differences in treatment efficacy were based on the PIONEER-HF clinical trial. The financial impact of changes in patient outcomes under the sacubitril/valsartan and ACEi/ARB arms was assessed across three APMs the Medicare Shared Savings Program, Bundled Payments for Care Improvement, and fee-for-service payments adjusted according to the Hospital Readmission Reduction Program.

Sacusitive net financial impact on health systems after accounting for APM bonus payments.

Sacubitril/valsartan adoption decreased hospitalizations and led to a positive net financial impact on health systems after accounting for APM bonus payments.
