Human exposure assessment tools represent a means for understanding human exposure to pesticides in agricultural activities and managing possible health risks. This paper presents a pesticide flow analysis modeling approach developed to assess human exposure to pesticide use in greenhouse flower crops in Colombia, focusing on dermal and inhalation exposure. This approach is based on the materia...

The effect of nine different pesticides on the growth of yeasts isolated from the leaves of fruit and forest trees was investigated. Four insecticides (with the active ingredients: thiacloprid, deltamethrin, lambdacyhalothrin, and thiamethoxam) and five fungicides (with the effective substances: bitertanol, kresoxim-methyl, mancozeb, trifloxystrobin, and cupric oxychloride) were tested. The con...

Field surveys were conducted in 3 major grapevine growing districts in Tamil Nadu viz., Coimbatore, Theni and Dindugal. The downy mildew infection on leaves was the highest (PDI 76.92 in Cumbum of Theni district. In the survey on the incidence of powdery mildew showed that the highest incidence of PDI on leaves, inflorescence and fruits in Cumbum of Theni with records of 65.49, 63.56, 61.23 per...

Most agronomic situations involve a sequence of herbicide, fungicide, and insecticide application. On the other hand, use of pesticidal combinations has become a standard practice in the production of many agricultural crops. One of the most important processes influencing the behavior of a pesticide in the environment is its degradation in soil. It is known that due to several pesticide applic...

We examined the effects of pesticides on the central and peripheral nervous system in the setting of a tobacco farm at a developing country. Maximal motor and sensory nerve conduction velocities (MCV and SCV, respectively) in the median, sural and tibial nerves, postural sway, and brain-evoked potentials (auditory event-related and visual-evoked potentials) were measured in 80 male tobacco farm...

Groundnut is infected by 55 pathogens which adversely contribute to the low yield of groundnuts. Three sub-trials were conceived proffer solutions groundnut Cylindrocladium parasiticum disease. These (using biocontrol, synthetic and botanical measures) set up in vitro using completely randomized design with each treatment replicated thrice. Firstly, all biocontrol (Trichoderma) isolates showed ...

Faba bean (Vicia faba L.) is a cool legume crop grown in the highlands of Ethiopia, and chocolate spot disease (Botrytis fabae Sard.) occurs wide areas. There shortage recorded data about impact on beans their management practices Ethiopia. The objectives this study were to assess influence sowing dates frequency foliar fungicide (mancozeb) application for spots determine association with occur...

Manganese (Mn), an essential nutrient, is a neurotoxicant at high concentrations. We measured Mn concentrations in repeated blood and hair samples collected from 449 pregnant women living near banana plantations with extensive aerial spraying of Mn-containing fungicide mancozeb in Costa Rica, and examined environmental and lifestyle factors associated with these biomarkers. Mean blood Mn and ge...

Efficacy of resistance induction by the bacterial isolates Pseudomonas putida (TRL2-3), Micrococcus luteus (TRK2-2) and Flexibacteraceae bacterium (MRL412), which were isolated from the rhizosphere of plants growing in Jeju Mountain, were tested in a greenhouse. The disease severity caused by Phytophthora infestans was effectively reduced in the potato plants pre-inoculated with bacterial isola...
