Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

Journal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

A Systematic Map to Identify Knowledge Gaps on a Vector of Citrus Greening Diseases: The African Citrus Triozid, Trioza erytreae (Del Guercio, 1918) (Hemiptera: Triozidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Globally, citrus production areas are threatened by greening diseases, also known as Huánglóngbíng (HLB), associated with phloem‐limited gram‐negative species of the genus Candidatus Liberibacter. Those pathogens are transmitted by either the Asian citrus psyllid, Diaphorina citri Kuwayama 1908 (Hemiptera: Psyllidae), or the African citrus ...

Feldspar Albitization With Implications for Reservoir Quality Evolution of Eocene Turbidite Sandstones in Offshore Espírito Santo Basin, Eastern Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

Study on Structure and Properties of Kaolin Composites- based Geopolymers

Chemical Engineering Transactions, 2018
In order to study the pore structure and corrosion resistance of kaolin composite-based geopolymers, in this paper, kaolin composite-based geopolymers were prepared by replacing fly ash with 15%, 25%, 35%, 50%, and 60% kaolin.

Long-Chain Diacrylate Crosslinkers and Use of PEG Crosslinks in Poly(potassium acrylate-acrylic acid)/Kaolin Composite Superabsorbents [PDF]

علوم و تکنولوژی پلیمر, 2013
Long-chain diacrylate crosslinkers based on linear α,ω-diols were synthesized and characterized using FTIR and 1H NMR spectroscopy. The highest reaction yield (99.5%) was due to polyethylene glycol diacrylate 1000 (PEGDA-1000).

Carryover of Aflatoxin From Dairy Feed to Milk: A Systematic Review (1 January 2004–31 December 2024)

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Aflatoxins, toxic metabolites produced by Aspergillus species, are frequently reported contaminants of dairy cattle feed worldwide, particularly in tropical and subtropical regions where climatic conditions favor fungal growth, and they can be transferred into milk and dairy products.

Effects of Meloidogyne incognita on agronomic parameters and structural changes in eggplant (Solanum gilo Raddi) roots treated with Purpureocillium lilacinum

Plant Biology, EarlyView.
Meloidogyne incognita impairs eggplant growth through gall formation with changes in root cell wall components and vascular tissue disruption, while the biocontrol agent Purpureocillium lilacinum mitigates these effects by reducing nematode infection. Abstract Meloidogyne spp. induce structural changes during the development of root‐knot galls, leading
