Evaluation of the Resistance of Five Tomato Varieties to Bacterial Wilt (Ralstonia solanacearum) under the Agro-climatic Conditions of Katibougou | Chapter 8 | Microbiology and Biotechnology Research: An Overview Vol. 4

 

The objective of this research is to contribute to the improvement of tomato productivity in Mali. Tomatoes remain one of the most widely grown vegetable crops in the world. It is the most consumed vegetable in the world after potatoes. However, its production faces enormous difficulties such as the extreme poverty of the soil, the low technicality of the producers, the high pest pressure and the scarcity of high-performance varieties. Of these, bacterial wilt is an important factor, as it causes a huge loss of production on average if left unchecked. A study was carried out on the evaluation of the resistance of five varieties of tomato (Anaya, Raja, Tingal, Mona and Petomek) to bacterial wilt (Ralstonia solanacearum) in the agro-climatic conditions of Katibougou. The experimental device used was the Fisher block with three (03) repetitions to five (05) treatments. The analysis of biometric observations shows that the Raja variety had the largest diameter at the collar with 12.13 cm at the 60th day after transplanting, the highest number of leaves at 40.1, it also gave the highest number of branches with 9.8 and also the greatest height of the plants with 82.5 cm. Regarding the incidence of bacterial wilt, the Petomek variety (T5) had the highest percentage with 73%, followed by the Anaya variety (T1) which had 70%. As for the severity, a total of three (03) observations were made, the analysis of variance showed a significant difference between the levels of variation, the Petomek variety (T5) had the highest score with 85.9%, followed by the Anaya variety (T1) which recorded 84.4% and finally the Tingal (T3) and Mona (T4) varieties had the lowest scores 24.4%. In terms of yield, the Tingal variety had the best yield with 45.83 t/ha, followed by the Mona variety with 39.46 t/ha. Finally, the Anaya and Petomek treatments gave the lowest yields with 21.66 t/ha and 20.55 t/ha, respectively.

Management of Bacterial Wilt disease of Brinjal by P. fluorescens Based Bioformulation: Experimental Investigation | Chapter 9 | Emerging Issues in Agricultural Sciences Vol. 2

 This experiment was completed activity to explore the aptitude of an indigenous strain of Pseudomonas fluorescens as a biography-control agent in the administration of bacterial wilt ailment of brinjal under local conditions. Bacterial sag is a major warning to brinjal production. Different natural materials were judged for their potential as substrate carriers in the expression of P. fluorescens based biopesticide. It was discovered that vermicompost and farmyard fertilizer significantly comprehensive the shelf life of the biocontrol microorganisms. In pot and field experiments, formulations of P. fluorescens established carboxy methyl cellulose and substrate one who carries or transmits something were used in differing ways to test their efficiency in preventing bacterial sag of brinjal. CVPf formulation and children + root + soil method of request performed considerably better than others providing 83.33% control of bacterial fail of brinjal in field experiment conducted by Completely Randomized Block Design. The yield and yield traits of CVPf-treated brinjal plants were further noticeably above those of other expression-treated brinjal crops. The P. fluorescens-located organic expression's capability and opportunity as a PGPR are indicated by allure successful control of the bacterial wilt of brinjal and bettering of yield and yield attributes under local conditions.

An Assessment of Extension Approaches for Bacterial Wilt Control with Potato Farmers in Ethiopia | Book Publisher International

 In Ethiopia's densely populated highlands, potato farming provides both food and cash income, contributing considerably to smallholder potato growers' food security and cash income. Ethiopian potato producers, on the other hand, face a number of problems, including a lack of access to improved high-yielding seed, seed tubers, and soil with a high frequency of bacterial infections, as well as a lack of agricultural extension services. In this study, three questions are investigated. How well do farmers understand bacterial wilt and how it affects potato production? How enthusiastic are farmers in taking collective/community action to combat bacterial wilt? Should farmers rely on local knowledge or scientific guidance to better their reaction to the condition? In 2015, the thesis was part of a wider research project called Developing a sustainable seed potato production system for enhanced livelihoods. The initiative is based in Chencha Woreda, in Ethiopia's SNNPR area, and is supported by Vita and Teasasc. The thesis employs a mixed method approach, with farmer surveys, key informant interviews, field observations, and focus group discussions. The study took place in two separate kebeles. The following were the study's goals: I will look into farmers' awareness of bacterial wilt (BW), (ii) analyse farmers' willingness to participate in collective action, and (iii) build the best-fit technological information channels for obtaining and sharing bacterial wilt management knowledge.

 

BW is the most important disease problem, according to the survey, and communities are well aware of it. Farmers' concerns about BW are justified, as the disease affects potato yields and poses a serious danger to potato output, food security, and farmer profitability. There is, however, a knowledge gap in BW management. In addition, there is inadequate data to pursue the best potato production management practises. These deficiencies affect three groups: the general public, farmers, and there is a special difficulty between female and male farmers in terms of their comprehension of BW. A lack of understanding of cultural control practises that may limit the spread of BW was identified to be a prevalent feature in the study. Furthermore, it was determined that more than half of the farmers tested lacked sufficient knowledge. The most significant finding is that nearly all farmers are willing to collaborate in the fight against bacterial wilt. Female farmers and impoverished farmers must be regarded an unique group that requires special attention from extension services, according to study data. Both male and female farmers require access to information, skills, and tools in order to boost yields. Farmers' contact with extension agents, on the other hand, was found to be low in general, and particularly low among female farmers. Peer-to-peer learning from fellow farmers, on-farm demonstrations, and farm visits to observe improved agronomic practises were selected as farmers' preferred methods of learning about BW. Non-state actors / private organisations have also been discovered to be major sources of information on BW. Churches, chiefs, community meetings, private agricultural firms, local FM radio, and on-farm advice services are also major information sources in some places. According to the report, considerable farmer gains require a combination of technical breakthroughs and collective action activities. It also recommends that the government and non-governmental organisations work together to help farmers, particularly women, implement BW-prevention techniques.
