Abstract:

In almond [Prunis dulcis (Mill.) D.A. Webb.], fungicide sprays are required to prevent blossom blight, which can infect open flowers. Numerous studies have reported detrimental effects of agrochemical sprays on pollination, fruit set, and yield in tree fruit crops. However, effects of fungicides on pollen germination and growth in almond are little known, particularly those from recently developed active ingredients. In this study we evaluated the effects of commercial formulations of 10 fungicides on pollen germination and tube growth in almond using in vitro assays. Assays conducted at 1/100

In vitro control of Alternaria solani included studies of different fungicides, essential oils basil and ethyl extract of Allium cepa. In Romania in the case of tomato culture it is very low due to several production constrains including diseases. One such disease is the early blight caused by fungus Alternaria solani (Ell.) Martin. The isolate used in this study was obtained from tomato and it was cultivated on three culture media: potato dextrose agar (PDA), malt extract agar and Czapek Dox medium.

Abstract:

A fundamental principle of integrated pest management is that actions taken to manage disease should be commensurate with the risk of infection and loss. One of the less-studied factors that determines this risk is ontogenic, or age-related resistance of the host. Ontogenic resistance may operate at the whole plant level or in specific organs or tissues. Until recently, grape berries were thought to remain susceptible to powdery mildew (Uncinula necator) until late in their development. However, the development of ontogenic resistance is actually quite rapid in berries, and fruit become nearly

Abstract:

Fungicide effectiveness on yield loss owing to eastern filbert blight (EFB) was studied on mature, bearing hazelnut trees in a replicated trial. This case study found that fungicide use in hazelnuts not only limited EFB development but also protected future yield loss and gross financial returns. The results were similar to commercial industry experience even though the research occurred on small blocks of mature trees. There was no difference in disease or yield between the two fungicide programs evaluated. Growers who carry the annual cost of fungicides after discovery of EFB in their orchar

The fungicide treatments had a strong impact on the control of infection of P. teres and increased kernel yield in variable disease infection conditions.

As a result of their composition mostly of natural elements old textiles are extremely prone to physical and chemical degradation due to fungal action. The treatments usually applied for the cleaning of heritage textiles target the use of synthetic fungicides, which are potentially harmful to both human health and the environment.

Pruned vine-shoots used as wine additives have proven to be a useful tool for improving and differentiating wines. This is because they accumulate substances from the plant itself, which later, as a result of the toasting process, express their greatest oenological potential. However, vine being one of the crops subject to the most phytosanitary treatments, including fungicides in particular, it can be assumed that their residues will accumulate in the vine-shoots and pass into the wine. The aim of this study was to determine the content in pruned vine-shoots of four of the main fungicides app

Abstract:

In order to investigate the effect of expired pesticides on the yield and growth rate of green algae Pseudokirchneriella subcapitata, a study was conducted as per the Organisation for Economic Cooperation and Development (OECD) guideline number 201. Fifteen expired pesticide formulations, most commonly used in Indian agriculture, were tested in comparison with their unexpired counterparts. The expired pesticide formulations studied belonged to various class and functional groups: organophosphate, pyrethroid-based insecticides; azole-based fungicides; acetamide, propionate, acetic acid-based he

Fungal keratitis is difficult to treat, especially Fusarium keratitis. In vitro studies show that chlorhexidine could be an interesting option as monotherapy. We describe a case series of four patients (four eyes) with Fusarium keratitis at Radboud University Medical Center (Nijmegen, the Netherlands). The patients were treated with chlorhexidine 0.02% eye drops. The in vitro activity of eight antifungals and chlorhexidine was determined according to the European Committee on Antimicrobial Susceptibility Testing (EUCAST) broth microdilution method.

N-Methyl-N-D-fructosyl amphotericin B methyl ester (MFAME) is a semisynthetic derivative of the antifungal antibiotic amphotericin B (AMB). In contrast to the parent antibiotic, the derivative is characterised by low toxicity to mammalian cells and good solubility in water of its salts. Comparative studies on biological properties of free MFAME, AMB and their liposomal formulations were performed. To obtain liposomal forms, the antibiotics were incorporated into small unilamellar vesicles composed of dimyristoyl phosphatidylcholine (DMPC) and DMPC:cholesterol or ergosterol, 8:2 molar ratio.
