Soil application of DBCP (l,2-dibromo-3-chloropropane) and foliar applications of oxamyl (methyl N',N'-dimethyl-N-[(methylcarbamoyl)oxy]-l-thiooxamimidate) were compared for control of Tylenchulus semipenetrans in a grapefruit (Citrus paradisi) orchard, DBCP reduced nematode populations and increased fruit growth rate, fruit size at harvest, and yield compared to the untreated controls in the 2...

Os óleos essenciais são substâncias voláteis extraídas de diversas partes das plantas e com propriedades diversas, entre elas a ação inseticida ou repelente. Objetivou-se, esse trabalho, testar os citronela (Cymbopogon nardus L.), copaíba (Copaifera sp.) laranja (Citrus sinensis L.) como repelentes alternativos sobre Apis mellifera L. Realizou-se um bioensaio experimental 320 abelhas capturadas...

Since citrus flowering is a key process in citriculture and its evaluation is often difficult due to the canopy structure and field sampling, the aim of this research was to give some directions regarding the evaluation of flowering in field-grown sweet orange plants. This study was conducted in a citrus orchard of sweet orange plants cv. ‘Valencia’ [Citrus sinensis (L.) Osbeck] grafted on ‘Cle...

BACKGROUND Use of plant extracts and phytochemicals with known antimicrobial properties may have great significance in therapeutic treatments. OBJECTIVE To assess the in vitro antimicrobial potential and also determine the minimum inhibitory concentration (MIC) of Citrus sinensis peel extracts with a view of searching a novel extract as a remedy for periodontal pathogens. MATERIALS AND METH...

This study sought to characterize the effects of some citrus fruit juices (shaddock [Citrus maxima], grapefruit [Citrus paradisii], lemon [Citrus limoni], orange [Citrus sinensis], and tangerine [Citrus reticulata]) on acetylcholinesterase activity in vitro. The total phenolic content, radical scavenging abilities, and inhibition of Fe(2+)-induced malondialdehyde (MDA) production in rats brain ...

sooty mold fungi are often associated with honeydew which insects secrete while feeding on the plant. a great variety of these fungi occur in the north of iran, especially on citrus ssp which is one of the most widely cultivated fruit trees in this region. during last 10 years, several collections of these fungi examined and 15 species have been recorded. in this paper seven previously unreport...

Fruit flies (Diptera: Tephritidae) represent a threat to fruit growing worldwide, mainly the citrus culture, however, biological studies show that fruit flies are not perfectly adapted to this host. This study investigated oviposition of Anastrepha fraterculus (Wiedemann, 1830) and Ceratitis capitata (Wiedemann, 1824) and its relation with the pericarp of citrus fruits. We evaluated the relatio...

In this work, seedlings of two citrus rootstocks, the salt-tolerant Cleopatra mandarin (Citrus reshni Hort. ex Tan.) and the salt-sensitive Carrizo citrange (Citrus sinensis [L.] Osb. x Poncirus trifoliata [L.] Raf.) were used to study the relationship between chloride and water uptake. The results indicated that net chloride uptake rates in both genotypes were alike and decreased linearly with...

Purpose: The availability of fresh Citrus fruits is limited by their susceptibility to invasion microbial pathogens which leads cause serious postharvest losses. present study was carried out isolate and morphologically identify fungal associations from selected fruit species (C. sinensis, C. limon, crenatifolia medica) confirm identity molecular characterization. Research method: Postharvest w...
