Seven fungicides were evaluated in vitro against Exserohilum turcicum causing leaf blight of maize The treatment mancozeb 0.25% and combination treatments of carbendazim and mancozeb i.e. saff 0.25% recorded the lowest percent disease index (PDI) reducing the disease by 73.0% and 72.1% respectively. The treatment which had a combination metriram + pyraclostrobin i.e. cabriotop 0.3% was found to...

mancozeb, a fungicide of a manganese-zinc ethylenebisdithio-carbamate (ebdc), was administered by gavage at doses of 200, 400, 600 and 800 mg/kg/day to female virgin mice for 30 days. the mice were autopsied on 31st day. mice were also treated with similar doses for a period of 30 days and the treatment was withdrawn for a further period of 30 days for reversible study. the mice were autopsied ...

This work examines the effects of six pesticides on five green algae: Pseudokirchneriella subcapitata, Scenedesmus quadricauda, Scenedesmus obliquus, Chlorella vulgaris and Chlorella pyrenoidosa. The results indicate that the decreasing order of the average toxicity to five algae was: fluazinam > propineb > maneb > mancozeb > zineb > bromoxynil octanoate. however, according to sensitivity magni...

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 histochemical effects of the lipid and the biochemical analysis of cholesterol content induced by mancozeb, a widely used fungicide in India and in Madhya Pradesh were observed on Swiss albino mice (Mus musculus albinicus). Three groups were used for the present experiment, where Group I was taken as control and was administered distilled water. Group II and III were the test groups receivi...

It is widely recognised that complex interactions occur between chemicals in mixtures. In many agricultural situations, the use of tank mixes and complex spray programs is a common practice. Insecticides, fungicides and a herbicide being applied in potato protection were used in this research. Interactions between linuron and insecticides, such as thiamethoxam or clothianidin, and fungicides, s...

In recent times, human cell-based assays are gaining attention in assessments of immunomodulatory effects of chemicals. In the study here, the possible effects of cypermethrin and mancozeb on lymphocyte proliferation and proinflammatory (tumor necrosis factor (TNF-) α) and immunoregulatory cytokine (interferon- (IFN-) γ, interleukins (IL) 2, 4, 6, and 10) formation in vitro were investigated. H...

Two hundred and fifteen green beans samples from an agricultural region of the Souss (Agadir, Morrocco) were analyzed for endosulfan, dithiocarbamate, bifenthrin, chlorothalonil, iprodion, procymidon and deltamethrin. Of 189 samples that contained pesticide residues, dithiocarbamates (mancozeb and mefenoxam) were detected in 43 (20 %) in the concentration range of 0.045 to 2.651 mg Kg-1. Four o...

Mancozeb, an ethylenebisdithiocarbamate fungicide was administered orally to male rats at doses 0, 500, 1000 and 1500 mg/kg/day for 90, 180 and 360 days produced dose dependent signs of poisoning, loss in body weight gain and mortality. However the signs of toxicity and mortality were more pronounced initially at 0-90 days as compared to 90-360 days of treatment period. A significant increase i...

The dithiocarbamate fungicide mancozeb is used extensively around the world for control of foliar diseases. Initial yield decline research in the early 1990s investigated soil application of fungicides for the amelioration of poor root health in sugarcane. Experiments in both the glasshouse and field have since shown that root health and plant growth improve dramatically following mancozeb appl...
