Mango production in the South of Senegal is exposed to intensive rainfall from late May to October, with high temperature and moisture levels. These conditions are conducive for the development of anthracnose caused by Colletotrichum gloeosporioides (sensu lato) and produce a need for adequate control measures. Anthracnose disease causes preand postharvest fruit spots, fruit rot, and premature ...

The effectiveness of 12 chemical compounds (azoxystrobin, carbendazim, chlorothalonil, fenarimol, folpet, mancozeb, myclobutanil + mancozeb, prochloraz + carbendazim, tebuconazole + triadimefon, tetraconazole + chlorothalonil, tiophanate-methyl, tridemorph + epoxiconazole) in the control of Puccinia horiana was tested on chrysanthemum cv. Fiji Yellow. Additionally, their influence on plant grow...

The objective of this work was to estimate the disappearance parameters of azoxystrobin, cyprodinil and fludioxonil initial deposits, active ingredients of Amistar 250 SC, and Switch 62,5 WG, at present, commonly used for the protection of fruits and vegetables against diseases of fungal origin. The tests were carried out on tomato plants grown in commercial greenhouses sprayed with homogenous ...

Strobilurins are one of the most important classes of agricultural fungicide. Their invention was inspired by a group of fungicidally active natural products. The outstanding benefits they deliver are currently being utilised in a wide range of crops throughout the world. First launched in 1996, the strobilurins now include the world's biggest selling fungicide, azoxystrobin. By 2002 there will...

The chemical management of the black leaf streak disease in banana caused by Mycosphaerella fijiensis (Morelet) requires numerous applications of fungicides per year. However this has led to fungicide resistance in the field. The present study evaluated the activities of six fungicides against the mycelial growth by determination of EC50 values of strains collected from fields with different fu...

Nanoparticles are of great interest for water treatment as they remove a significant portion contaminants. In analogy to these emerging practices, the present work investigated feasibility using silica nanoparticles (SiO2-NPs) azoxystrobin from an aqueous solution. We effects experimental parameters, such solution temperature, adsorbent dosage, contact time, and initial concentration, on remova...

Peronophythora litchii is the causal agent of litchi downy blight. Enestroburin, SYP-1620, SYP-2815 and ZJ0712 are four novel QoI fungicides developed by China. Eight mutants of P. litchii resistant to these QoI fungicides and azoxystrobin (as a known QoI fungicide) were obtained in our preliminary work. In this study, the full length of the cytochrome b gene in P. litchii, which has a full len...

Isolates of three fungal species associated with citrus, Phyllosticta citricarpa, Phyllosticta citriasiana and Phyllosticta capitalensis, collected from different citrus growing countries of the world, were investigated for their sensitivities to the QoI fungicides pyraclostrobin and azoxystrobin. Isolates were highly sensitive in microtiter tests and EC50 values were in narrow ranges, which in...

In tropical regions, protozoan parasites can cause severe diseases with malaria, leishmaniasis, sleeping sickness, and Chagas disease standing in the forefront. Many of the drugs currently being used to treat these diseases have been developed more than 50 years ago and can cause severe adverse effects. Above all, resistance to existing drugs is widespread and has become a serious problem threa...
