[Making strides facing "second flowering" syphilis papules].

Numai utilizatorii înregistrați pot traduce articole

In a recent past, the incidence of syphilis has increased in various geographical regions, particularly in urban areas. In addition, the disease is particularly associated with HIV infection. In secondary syphilis, the diagnosis may prove to be particularly difficult to reach because the

Evaluation of antibacterial, antifungal, and antioxidant activities of safflower natural dyes during flowering.

Numai utilizatorii înregistrați pot traduce articole

Two Carthamus tinctorius varieties (Jawhara and 104) were studied in order to investigate their natural dyes contents and biological activities. Obtained results showed that quinochalcone contents and antioxidant activities varied considerably as function of flowering stages. So flowers at

Translocation and degradation of tebuconazole and prothioconazole in wheat following fungicide treatment at flowering.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Prothioconazole and tebuconazole are among the most effective fungicides against Fusarium head blight (FHB) of wheat (Triticum aestivum L.). The translocation between the ears and the flag leaves and the kinetics of degradation may influence field efficacy of these active ingredients

Effect of the Timing of Fungicide Application on Fusarium Head Blight and Mycotoxin Accumulation in Closed-Flowering Barley.

Numai utilizatorii înregistrați pot traduce articole

Fungicide application is one measure available to reduce the risk of Fusarium head blight (FHB) and mycotoxin contamination in barley. The stage at or near anthesis, or at full head emergence, is generally thought to be optimal for fungicide application, regardless of cultivar. However, we have

Flowering and floral visitation predict changes in community structure provided that mycorrhizas remain intact.

Numai utilizatorii înregistrați pot traduce articole

Pollination is critical for plant fitness and population dynamics, yet little attention is paid to the role of flowering and plant-pollinator interactions in structuring plant communities, including community responses to environmental change. Changes in arbuscular mycorrhizal fungi (AMF), nutrient

Essential oil composition and antifungal activity of aerial parts of Ballota nigra ssp foetida collected at flowering and fruiting times.

Numai utilizatorii înregistrați pot traduce articole

The present study reports the results of gas chromatographic-mass spectrometric (GC/MS) analyses of the essential oils from the aerial parts of Ballota nigra L. ssp foetida (Lamiaceae) collected at flowering and fruiting times, as well as their in vitro antifungal activity against nine plant

Antimicrobial Activity of Essential Oil of Baccharis dracunculifolia DC (Asteraceae) Aerial Parts at Flowering Period.

Numai utilizatorii înregistrați pot traduce articole

Baccharis dracunculifolia DC (Asteraceae) is a Brazilian native bush tree, and its leaf essential oil has been reported to possess some biological activities, but the antimicrobial activity of its aerial part essential oil at the flowering period is unknown or little studied, mainly against

Distribution of prothioconazole and tebuconazole between wheat ears and flag leaves following fungicide spraying with different nozzle types at flowering.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Wheat ears are difficult targets from the aspect of fungicide spraying. Sideward-spraying nozzle types may enhance the ear coverage, which may possibly lead to higher effectiveness in the management of Fusarium head blight (FHB). RESULTS On average, sideward-spraying Turbo TeeJet Duo

Uptake, translocation and accumulation of the fungicide benzene kresoxim-methyl in Chinese flowering cabbage (Brassica campastris var. parachinensis) and water spinach (Ipomoea aquatica)

Numai utilizatorii înregistrați pot traduce articole

Benzene kresoxim-methyl (BKM) is an important methoxyacrylate-based strobilurin fungicide widely used against various phytopathogenic fungi in crops. Uptake, translocation and accumulation of BKM in vegetables remain unknown. This study was designed to investigate uptake, translocation, and

Bioactivity, proximate, mineral and volatile profiles along the flowering stages of Opuntia microdasys (Lehm.): defining potential applications.

Numai utilizatorii înregistrați pot traduce articole

Opuntia spp. flowers have been traditionally used for medical purposes, mostly because of their diversity in bioactive molecules with health promoting properties. The proximate, mineral and volatile compound profiles, together with the cytotoxic and antimicrobial properties were characterized in O.

Comparative Performance of Fungicides, Biofungicides, and Host Plant Defense Inducers in Suppression of Phytophthora Root Rot in Flowering Dogwood During Simulated Root Flooding Events.

Numai utilizatorii înregistrați pot traduce articole

During flooding events in nurseries, Phytophthora root rot caused by Phytophthora cinnamomi Rands often causes damage that leads to complete crop loss. In this study, we evaluated the efficacy of fungicides, biofungicides, and host plant defense inducers for preventive and curative control of

The effects of iprodione fungicide on survival, behavior, and brood development of honeybees (Apis mellifera L.) after one foliar application during flowering on mustard.

Numai utilizatorii înregistrați pot traduce articole

A semifield study to assess the effects of iprodione on honeybees at label use rates was conducted on a bloom mustard crop. The present study followed the Organisation for Economic Co-operation and Development guideline 75 tunnel test and consisted of 3 groups: the iprodione-treated group, the

Development of a tightly regulated and highly responsive copper-inducible gene expression system and its application to control of flowering time.

Numai utilizatorii înregistrați pot traduce articole

CONCLUSIONS A newly developed copper-inducible gene expression system overcame the mixed results reported earlier, worked well both in cultured cells and a whole plant, and enabled to control flowering timing. Copper is one of the essential microelements and is readily taken up by plants. However,

Effect of Seeding Rate and Seed Treatment Fungicides on Agronomic Performance, Fusarium Head Blight Symptoms, and DON Accumulation in Two Winter Wheats.

Numai utilizatorii înregistrați pot traduce articole

Fusarium head blight (FHB), caused by Fusarium graminearum, is an important disease of wheat (Triticum aestivum). FHB reduces yield and quality, and the pathogen produces several toxins in the grain, the most important being deoxynivalenol (DON). In North America, the foliar fungicide tebuconazole
