Background: Pigeon pea (Cajanus cajan) is one of the important leguminous crop of the tropics and subtropics and is infected by the wilt pathogen Neocosmospora vasinfecta in addition to Fusarium udum. Objective: Hence, the study was undertaken to see the in vitro effect of different fungicides (Thiram 75 WP, Carbendazim 50 WP, Chlorothalonil 75 WP, Metalaxyl MZ 72 WP, Thiram+Cabendazim (2:1), C...

Sublethal exposure to fungicides can affect honey bees (Apis mellifera L.) in ways that resemble malnutrition. These include reduced brood rearing, queen loss, and increased pathogen levels. We examined the effects of oral exposure to the fungicides boscalid and pyraclostrobin on factors affecting colony nutrition and immune function including pollen consumption, protein digestion, hemolymph pr...

IN 1996, the U.S. Congress unanimously passed the Food Quality Protection Act (FQPA). Among other things, the law formalized the U.S. Environmental Protection Agency’s (EPA) Reduced-Risk Pesticide Program (initiated in 1993) and mandated that EPA continue to enhance it (EPA 2003, 2004). The FQPA expedited EPA’s review and registration decision-making process for pesticides that are classified a...

Health affecting, loss-inducing or otherwise harmful fungal pathogens (molds) pose a serious challenge in many areas of human activities. On the contrary, frequent use of synthetic fungicides is undesirable in some cases and may be equally problematic. Moreover, the ever more increasing fungal resistance against commercial synthetic fungicides justifies development of rising efforts to seek new...

Dithiocarbamate fungicides such as maneb and mancozeb are widely used nonsystemic protectant fungicides to control various plant fungal diseases. Dithiocarbamate fungicides should be frequently applied to achieve optimal efficacy of disease control and avoid either decline in effectiveness or wash-off from leaf surface. Dithiocarbamates are of low resistance risk but have the potential to cause...

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...

laboratory degradation studies were performed in water at ph 4.0, 7.0 and 9.2 using prochloraz (450 ec) formulation at the rates of 1.0 (t1) and 2.0 (t2) î¼g/ml. water samples collected on 0 (2h),3,7,15,30,45,60 and 90 days after treatments were processed for residue analysis of prochloraz by hplc-uv detector. in 60 days, dissipation was 89.12-90.53 % at ph 4.0, 84.10-88.17 % at ph 7.0, and 92....

We report two cases of occupational asthma caused by sensitisation to powdered fungicides fluazinam and chlorothalonil, from the same fungicide formulation plant. Both developed work related lower respiratory symptoms after a latent interval of asymptomatic exposure. The diagnosis in each case was confirmed with a serial peak flow record in the workplace followed by specific inhalation tests. T...

Bacteria are generally the predominant initial inhabitants of newly expanded leaves, while yeast and filamentous Fungi dominate later in the growing season (Srivastava and Shalini, 2008). The extraordinary use of chemical fungicides resulted in environmental pollution and ill health to biotic community as a whole. Therefore biological method of plant disease management seems to be a better alte...
