In the last 20 years, pathogens that invade wood i.e. vascular tissues of trees causing wilt, yellowing, premature defoliation, cankers and tree death, have been on the rise. Diplodia corticola causes Bot canker of oak species which can kill trees diminishing the valuable ecological services they provide and reducing profits from wood and cork production. Since this and similar pathogens have difficult biologies because they reside in wood and cause severe internal damage and tree death, their management is difficult or inefficient with classical pesticide application methods that cannot reach and distribute the active ingredient in vascular wood tissues. As practical management options for this and other vascular tissue pathogens of trees are limited, we evaluated efficacy of several trunk injected fungicides in control of D. corticola and compared it with the efficacy of trunk injection of similar compounds for control of Venturia inaequalis and Erwinia amylovora , as two well-studied apple tree pathogens with different or partially similar lifestyles to D. corticola , respectively .","PeriodicalId":151191,"journal":{"name":"Plant Diseases - Current Threats and Management Trends","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123884611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sisal yields a coarse and strong fibre that is increasingly being used in composite materials for automobiles, furniture, construction and plastic and paper products. Extracts of sisal contain substances with anti-inflammatory, antimicrobial and anthelmintic activities. Sisal is adapted to warm environments with low rainfall and is an excellent option for cultivation in semiarid conditions, where other crops cannot be grown. The world’s largest sisal producers are Brazil, Tanzania, China, Kenya and Madagascar. Sisal is a labour-intensive crop with great socio-economical importance as it is cultivated in poor areas employing familiar labour. Sisal bole rot is the main disease of sisal, responsible for substantial losses in producing countries. The disease is caused by certain species of the genus Aspergillus , especially the ones belonging in the section Nigri . The main symptoms are yellowing of the aerial parts and the red-coloured rot of the bole, which causes the plant to die. In this review we are going to address the taxonomy of the causal agents, disease diagnosis and epidemiology and disease management, with emphasis on biological control.","PeriodicalId":151191,"journal":{"name":"Plant Diseases - Current Threats and Management Trends","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129962427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tobamoviruses are highly stable plant viruses that could cause severe disease symptoms. The well-known tobamovirus Cucumber green mottle mosaic virus (CGMMV) has recently caused severe damages in the cucumber, melon, and watermelon cucurbitaceous crops, worldwide. Similarly, a recent widespread of the newly identified tobamoviruses, Tomato mottle mosaic virus (ToMMV) and Tomato brown rugose fruit virus (ToBRFV), has reduced the solanaceous crop production. The primary route of tobamoviral infection is through mechanical means. These viruses adhere to agricultural facilities, contaminate the soil, infect seeds, and spread via beneficial pollinators and irrigation water. Mechanical plant injury suf-fices to initiate viral infection. Practicing hygiene by plant growers and in nurseries is currently the main strategy for mitigation of tobamoviral infection. Promoting the production of solanaceous vegetable crops genetically resistant to ToMMV and ToBRFV infection is a promising approach. However, CGMMV-resistant sources of cucurbitaceous vegetable crops are scarce. Conferring resistance to rootstocks and cross-protection strategies are newly implemented approaches that could alleviate tobamovirus disease spread in both solanaceous and cucurbitaceous crops.","PeriodicalId":151191,"journal":{"name":"Plant Diseases - Current Threats and Management Trends","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132909669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plant pathogen that causes Witches’ Broom disease of lime (Candidatus Phytoplasma aurantifolia) is a major limiting factor in lime production across the Middle East and was recently detected in Brazil, but without the typical symptoms from the Middle East. Here, we discuss the difficulty of monitoring asymptomatic infections and highlight the threat posed by highlight future outbreaks. Asymptomatic infections have important implications for understanding the evolution of pathogens within perennial hosts. We use three model systems of asymptomatic infections: (i) a Phytoplasma and (ii) a bacterial infection of lime (Citrus aurantifolia) and (iii) an “out-group” Phytoplasma of Cassava (Manihot esculenta) to demonstrate consistency across divergent hosts. We found that although all plants in the study were intentionally infected, assays typically did not confirm this diagnosis. Emergent technologies monitoring gene expression could be used to both study novel biology associated with asymptomatic infections and develop monitoring technologies. We highlight the difficulty of monitoring asymptomatic infections in possible future outbreaks and have important implications for understanding the evolution of pathogens within perennial hosts.","PeriodicalId":151191,"journal":{"name":"Plant Diseases - Current Threats and Management Trends","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127200701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
