We have synthesized surface modified ZnS nanoparticles of size 2-3 nm using non-ionic surfactant-stabilized reverse emulsions. The non-ionic surfactants in the Span series, i.e. sorbitan monolaurate (Span 20) and sorbitan monooleate (Span 80) of hydrophilic-lipophilic balance (HLB) values of 8.6 and 4.3, respectively, have been used for the stabilization of emulsions. The role of these surfacta...

The most prominent problem in the current citrus industry worldwide is epidemic of Huanglongbing (HLB), also known as greening disease. Huang et al. identified a stable peptide, which has antimicrobial activities and induces systemic immune response against HLB, from Australian finger lime. This peptide effectively suppresses disease symptoms protects healthy trees this

Huanglongbing (HLB) disease is threatening the sustainability of citriculture in affected regions because its rapid spread and severity symptoms it induces. Herein, we summarise main research findings that can be exploited to develop HLB-resistant cultivars. A major bottleneck has been lack a system for ex vivo cultivation HLB-associated bacteria (CLs) true plant hosts, which precludes evaluati...

Machine learning is a branch of computer science concerned with developing algorithms & models capable ‘learning through data and iterations’. Deep simulates the structure function human organs diseases using artificial neural networks more than one hidden layer. The primary purpose this work to develop test vision machine for classifying Huanglongbing (HLB)-infected, he...

Aspects of the incidence and spread of the citrus disease huanglongbing (HLB) in relation to the vector Diaphorina citri population fluctuation were studied from January 1999 to December 2001 seasons in a 0.8 ha citrus orchard at Jemukan (1° 33'N, 110° 41'E), Southwest Sarawak in Malaysia. In relation to insecticide and horticultural mineral oils (HMOs) use, levels of HLB infection rose quite r...

This review highlights bioemulsifier-producing marine microorganisms, which are capable of producing unique metabolites having industrial applications. High molecular weight biosurfactants (bioemulsifiers) produce stable emulsions, which allow bacteria to adhere strongly to hydrophobic surfaces and then degrade large biological complexes. Bioemulsifiers are classified according to their hydroph...

BACKGROUND The purpose of this study was to select appropriate surfactants or blends of surfactants to study the ternary phase diagram behavior of newly introduced palm kernel oil esters. METHODS Nonionic surfactant blends of Tween(®) and Tween(®)/Span(®) series were screened based on their solubilization capacity with water for palm kernel oil esters. Tween(®) 80 and five blends of Tween(®) ...

Hyperspectral (HS) imaging has become an efficient tool for agriculture applications. While HS image can provide large amounts of information, it has high redundancy because the bands of HS image are highly correlated. To solve citrus greening disease (Huanglongbing, or HLB) detection problem using airborne HS image, an efficient dimension reduction method needs to be applied, to improve the ac...

Huanglongbing (HLB) is a severe citrus (Citrus spp.) disease associated with the bacteria genus Candidatus Liberibacter, detected in Brazil in 2004. Another bacterium was found in association with HLB symptoms and characterized as a phytoplasma belonging to the 16SrIX group. The objectives of this study were to identify potential leafhopper vectors of the HLB-associated phytoplasma and their ho...
