We read the paper by Parks et al. with interest, particularly the increased risk of rheumatoid arthritis (RA) reported for maneb and mancozeb pesticide use (odds ratio [OR] = 3.3; 95% confidence interval [CI]: 1.5, 7.1). We suggest that these findings are explained by heavy metal exposure. Maneb and mancozeb fungicides are approximately 21% manganese by weight (Gunier et al. 2014). Their use is...

The most devastating disease that affects ginger production and productivity in Southwestern Ethiopia lowers qualitative quantitative rhizome yields is leaf spot, which caused by the pathogen Phyllosticta zingiberi. In Tepi, Ethiopia, during main cropping seasons of 2020 2021, a field experiment was carried out to assess efficacy several fungicides managing epidemics spot disease. evaluated wer...

RESUMEN Debido a que la información sobre el uso de fungicidas para control roya asiática soja (RAS) en Paraguay es escasa, objetivo este trabajo fue evaluar efecto 18 tratamientos (fungicidas sitio-específicos aplicados forma aislada y combinación con mancozeb) RAS. Se realizaron dos ensayos La Paloma (Canindeyú, Paraguay) épocas siembra (S1: 10/10/2018 S2: 20/01/2019) bajo un diseño factorial...

Almond red leaf blotch is the most important fungal disease that is caused by the fungus Polystigma amygdalinum. Symptoms depending on the cultivar almond trees can be seen almost all year. In this study the effect of 5 fungicides (Copper oxychloride  2000 µg/ml, Bordofix 2000 µg/ml, Mancozeb 200 µg/ml, Bordo Compound 10000 µg/ml, Triforin 300 µg/ml with rep.control) was examined in a randomize...

Environ.Entomol.13: 1010-1014 (1984) ABSTRACT Field experiments were carried out to determine if a copper-based fungicide known to deter feeding by the Colorado potato beetle, Leptinotarsa decemlineata (Say), in the laboratory, could suppress the growth of L. decemlineata populations in the field when used regularly for plant disease protection on tomatoes, potatoes, and eggplants. Larval densi...

Some pesticide chemicals are based on inorganic elements such as sulfur, copper (i.e. copper sulfate ‘Bordeaux mixture’, copper hydroxide, and copper oxychloride), and arsenic salts (i.e. lead arsenate, calcium arsenate, sodium arsenite), or they contain an inorganic element in their chemical structure such as the organometallic pesticides based on manganese dithiocarbamate (maneb), manganese a...

Potato brown spot caused by Alternaria alternata (Fr.) Keissler is one of the most destructive diseases potato worldwide. The present study was conducted to identify causal agent, and test efficacy several fungicides with different modes actions against A. alternata. Five chemical including; Copper oxychloride (Sufer Oxychloride® 50% WP), Carbendazim (Carbendazim Aria® 60% Penconazole (Penconaz...

Reduced sensitivity to quinone outside inhibitor (QoI) fungicides conferred by the presence of the F129L mutation was identified in Alternaria solani isolates collected in Nebraska in 2000 and in isolates collected from the Midwestern states of Minnesota and North Dakota in 2001. Over 4200 isolates of A. solani collected over a 5-year period from 2002 to 2006 from 11 potato-producing states wer...
