Abstract Background Pesticides have become a central public health problem and source of environmental contamination. The use organic matter is an important strategy to reduce synthetic agrochemicals, improve soil conditions, increase nutrient uptake by plants. Organic can also induce plant resistance against biotic stress in some circumstances. However, the results reported for different types...
Bacterial spot disease on peppers is caused by four species of the genus Xanthomonas. This causes black lesions not only leaves but also fruit, leading to yield and quality loss. Xanthomonas cause major outbreaks in tropical, subtropical humid continental regions worldwide. blight xanthomonads occurs both greenhouse- field-grown particularly important areas characterized hot environmental condi...
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 ...
Extensive applications of organochlorine pesticides like endosulfan have led to the contamination of soil and environments. Five different bacteria were isolated from cockroaches living in pesticide contaminated environments. According to morphological, physiological, biochemical properties, and total cellular fatty acid profile by Fatty Acid Methyl Esters (FAMEs), the isolates were identified ...
Pathogen effectors are virulence factors causing plant diseases. How the host targets of these effectors facilitate pathogen infection is largely unknown. An effector of Xanthomonas oryzae pv oryzae (Xoo) transcriptionally activates rice (Oryza sativa) susceptibility gene Xa13 to cause bacterial blight disease. Xa13 encodes an indispensable plasma membrane protein of the MtN3/saliva family, whi...
One of the major problems with pesticides is linked to non-negligible proportion sprayed active ingredient that does not reach its intended target and contaminates environmental compartments. Here, we have implemented provided new insights preventive bioremediation process based on simultaneous application pesticide pesticide-degrading microorganisms reduce risk leaching into environment. This ...
Pesticides are widely applied in agriculture to combat disease, pests, and weeds, leading long-lasting contamination of agricultural soils with pesticide residues. While classical risk assessment experiments have repeatedly addressed immediate effects, we employ an ecological approach investigate how residues persisting influence the soil microbiome under realistic conditions. We assessed a wid...
Organochlorine pesticides are one of the major groups of chemicals responsible for environmental contamination. Endosulfan a pesticide used mainly in cashew plantation is a highly toxic endocrine disrupter and a contact stomach poison. To study the endosulfan degrading microorganisms, 20 soil samples were collected from five different cashew plantations having a history of endosulfan applicatio...
پوسیدگی ذغالی سویا هر ساله خصوصا در سالهای خشک و کم باران باعث آلودگی مزارع سویا شده و موجب کاهش کمیت و کیفیت محصول می گردد و می تواند 23 الی 100 درصد محصول را از بین ببرد. قارچ های piriformospora indica و sebacina vermifera در مقایسه با دیگر قارچ های میکوریز همزیست های اختیاری گیاهان بوده و قادرند جدا از میزبان خود رشد نمایند. به منظور کشت مصنوعی این قارچ ها فاکتورهایی نظیر دما، ph و محیط کشت ...
