Sweet pepper ( Capsicum annum ) is an important vegetable with high economic and nutritional value. The present study was conducted to evaluate the effectiveness of biological treatments on nutritional, nutraceutical functional status greenhouse sweet peppers cv. Nirvin. Plants were divided into two categories: Peppers that biologically treated included five microbial-based fertilizers insectic...
Pesticides are very hazardous and lethal for organisms as well as for humans. They present danger to consumers, bystanders and workers during manufacture, transport or, during and after use. Pesticides are also toxic to plants and many food crops, including fruits and vegetables, contain pesticide residues after being washed or peeled. Pesticides decrease the biodiversity in soil and it has bee...
Background and Objectives: Water pollution by pesticides has adverse effects on the environment and human health, as well .In recent years, advanced oxidation processes, have been gone through to a very high degree for pesticides removal. Poly-Aluminum chloride (PAC) used for water treatment, can be effective on pesticides removal. The aim of this research was to study the use of UV/O3 and ...
Retention and degradation of co-applied atrazine fipronil was studied in laboratory constructed bio-augmented biobeds containing rice straw-compost (BM) compost replaced with 10% husk ash [RHABM(10%)] or 1% wheat straw biochar [WBCBM(1%)] biomixtures. Atrazine (5000 µg, 50% WP) 0.3 G) were 100 mL water. After 30 days, 7.31, 4.65, 11.21 µg g−1 21.59, 7.41, 37.20 remained undegraded the top 3–4 c...
Pesticides are essential tools in integrated pest management (IPM) programs which can have the great influence if they are used properly. However, the adverse impacts of these compounds on the environment and ecosystem should not be ignored. The ecological effects of pesticides can be discussed from different points of view. Some of the significant consequences of use of pesticides are side eff...
All aerial plant surfaces are inhabited by diverse assemblages of microorganisms, including bacteria, fi lamentous fungi, yeasts, and algae. These organisms have profound effects on plant health and thus impact on the ecosystem (Lindow and Brandl, 2003). The yeasts form a major component of the population on leaves (Inácio et al., 2002). Leaf surfaces are colonized by members of several genera ...
BACKGROUND AND METHODS Assessing the effects of pesticide hazards on microbiological processes in the soil is currently based on analyses that provide limited insight into the ongoing processes. This study proposes a more comprehensive approach. The side effects of pesticides may appear as changes in the expression of specific microbial genes or as changes in diversity. To assess the impact of ...
Microbial diversity of hydrocarbon in polluted soil and water bodies explains the variability that exists among various species microorganisms inhabiting such environments. Sources these pollutions include others polycyclic hydrocarbons, heavy metals contamination, industrial wastes unregulated use pesticides. No doubt, Niger Delta region is heavily due to exploration activities petroleum prosp...
Carbofuran (2,3-dihydro-2-2-dimethyl-7-benzofuranyl-Nmethylcarbamate) is a very effective systemic and contact insecticide and nematicide used against a wide range of agricultural pests (Aquino and Pathak, 1976; Caro et al., 1973). Though less persistent than most organochlorine pesticides, carbofuran is more toxic to animals, it is very soluble in water and tends to degrade faster under floode...
Plants are prone to various biotic stresses in nature by bacteria, viruses, fungi, parasites, harmful insects and weeds. The biggest percentage loss (70%) in plants is attributed to insects. Lepidoptera is one such diversified phytophagous insect group, which include Helicoverpa armigera, a key pest of many food crops including chickpea, pigeonpea, pea, lentil, chillies, sunflower, tomato, toba...
