Abstract: Mango is a significant fruit crop in our country, but it is often attacked by anthracnose, a disease that causes considerable pre and post-harvest losses. There are different methods to control this disease but management through the use of various fungicides, often in combination is more suitablef, under field conditions. This study was conducted in vitro experiments using the poison food technique to induce anthracnose disease in mangoes. Efficacy of 10 different fungicides was investigated, including contact fungicides like Blitox (Copper oxychloride 50% WP) and Indofil M-45 (Mancozeb 75% WP), as well as systemic fungicides like Topsin-M 70 WP (Thiophanate-M methyl 70% WP), Amistar Top (Difenconazole @ 12.5%), Aliette (Fosetyl Aluminium 80%), Score (Difenconazole @ 25% EC), Meriman (Captan WP 50%), Tilt (Propiconazole 25% EC), mirador (Azoxystrobin @ 20%), and Native (Tebuconazole+ Trifloxystrobin 75% WG). These fungicides were tested at three concentrations (0.05, 0.1, and 0.15) to evaluate their effectiveness in inhibiting the growth of Colletotrichum gloeosporioides, the causal agent of anthracnose in mangoes. The results of this study showed that among the fungicides tested, Tilt (Propiconazole 25% WP), a systemic fungicide, exhibited superior inhibition, achieving complete 50 percent mycelial inhibition and preventing sporulation across all three concentrations. In contrast, Meriman (Captan WP 50%) showed the lowest inhibition, at 31.57 percent, compared to the other fungicides tested. These findings underscore the importance of selecting the appropriate fungicide for effective management of anthracnose in mango crops.

Abstract: The importance of RhD-negative blood in clinical blood transfusion is becoming more and more prominent with the continuous advancement of medical technology, but the resources of blood donors are especially precious due to their rarity. As a densely populated area, the recruitment and retention of RhD-negative blood donors in Chongqing Municipality is crucial to ensure clinical blood supply. In this study, a questionnaire survey method was used to collect 1,200 valid questionnaires from RhD-negative blood donors in Chongqing Municipality during 2019-2021 by random sampling. The questionnaires covered the donors' knowledge of RhD-negative blood, knowledge of blood donation policy, motivation to donate blood, experience of blood donation and willingness to donate blood again. The data were statistically analyzed using SPSS software to explore the key factors affecting the willingness to donate blood through descriptive statistics and chi-square test. The results showed that factors such as donors' knowledge of RhD-negative blood, knowledge of blood donation policy, motivation and experience of blood donation significantly affected willingness to donate blood. Therefore, measures such as strengthening the publicity of RhD-negative blood knowledge, improving the blood donation policy, and upgrading the quality of blood donation services are recommended to promote the stable development of the RhD-negative blood donor workforce, to meet the urgent clinical demand for RhD-negative blood, and at the same time to enhance the satisfaction of the donors and the blood donation rate.
