This study was done to identify pesticide-biodegrading microorganisms and characterize degradation rates. Bacillus safensis strain FO-36bT, subtilis subsp. inaquosorum KCTC13429T, cereus ATCC14579T were isolated from pesticide-polluted soil in Sudan, separately incubated with each pesticide periodic samples drawn for GC GC-MS. Pesticide biodegradation followed a biphasic model. α β half-lives (days) of chlorpyrifos, malathion, dimethoate B. culture 2.13, 4.76; 2.59, 5.66; 9.5, 11.0,...

Biodegradation of endosulfan (α and β) pendimethalin by Bacillus safensis strain FO-36bT, subtilis subsp. inaquosorum KCTC 13429T cereus ATCC14579T isolated from pesticides-polluted soil was studied in mineral salt medium. Endosulfan were incubated with the three bacterial strains samples drawn at various intervals for GC analysis. Representative subject to GC–MS The loss initial concentrations, 0.663 mM endosulfan), 0.319 (β endosulfan) 1.423 (pendimethalin), monitored used compute...

A descriptive cross sectional study was carried out in Khartoum State to assess the knowledge, attitude, and practice of farmers towards pesticide residues on vegetables grown greenhouses. Fourteen from seven localities were selected interviewed. The results revealed that majority (92.9%) between age 25 45 years old, while only one farmer (7.1%) aging more than old. Regarding educational level, showed 20% illiterates, whereas 40% had completed secondary high school, university graduates....

Cowpea weevil causes losses of 50–90% in cowpea after harvest. Control has relied on toxic agrochemical fumigants that are no longer available or dangerous and relatively expensive, making its control difficult for most farmers. This study was initiated to investigate alternative methods synthetic pesticides, namely the suitable fumigation period oil concentration volatile oils garlic, Allium sativum, were evaluated as a fumigant against adults weevil, Callosobruchus maculatus (Bruchidae:...

Eggplant is a popular food item in Sudan, however pesticides are heavily used.To investigate the presence of pesticide residues fresh eggplants Khartoum State, Sudan.Eggplant fruit samples from three different regions State (central vegetable market, east Nile farms, and west farms) were analyzed for commonly used pesticides. Pesticide by gas chromatography coupled with mass spectrometry results expressed μg/kg fruit.Out 11 active ingredients analyzed, identified four (imidacloprid,...

Pesticides have been used for decades to protect agricultural products and increase productivity by controlling crop pests. However, the frequent application of pesticides on crops or soil leads accumulation their residues in environment, which will be subsequently absorbed plants finally translocated edible parts. This study aimed investigate uptake soil-applied dinotefuran three major metabolites lettuce celery from previous season’s applications analyze consumable Dinotefuran was at plant...

Ninety-nine human blood samples were collected from the riverine region of northern Sudan and traditional mechanized rain-fed areas western eastern Sudan, representing limited pesticide use in Sudan. Blood analyzed for organochlorine pesticides by gas liquid chromatography (GLC) followed electron-capture detection (ECD). p,p′-DDE (a metabolite DDT), heptachlor epoxide, β-hexachlorocyclohexane (β-HCH), dieldrin detected all locations surveyed. The level total burden was highest area, area. A...

ISHS IV International Date Palm Conference TRUNK INJECTION WITH NEONICTONIODS INSECTICIDES TO CONTROL THE GREEN PIT SCALE INSECT (PALMAPSIS PHOENICIS RAMACHANDRA RAO) (HOMOPTERA: ASTEROLECANIIDAE) INFESTING DATE PALM IN NORTHERN SUDAN

The knowledge of eggplant farmers on the proper use pesticides was evaluated in Khartoum State. Questionnaire distributed to North Nile Farms (NN), East (ENF), and West (WNF) solicit information. Interviews questionnaires revealed that there is a limited level awareness among farmers. majority (94%) did not abide by recommended disposal procedures, they only damage bury containers inside farms. (66%) were aware safety period for any given product. excessive production reliance as pest...

Experiments were undertaken in Elgaba scheme for two seasons (1999/2000 and 2000/2001) to evaluate the efficacy of imidacloprid (as Confidor 200SL) as part a technical cultural practices package (earthing, pruning regular irrigation) control date palm green pit scale insect Asterolecanium phoenicis (Rao). Four doses 200SL (15, 20, 25 35 ml/palm) compared with standard insecticide carbofuran (Furadan 5G (60g/palm) untreated control. A Completely Randomized Design six replicates (one =...

Laboratory experiments were conducted to evaluate the efficacy of three types garlic oils; Sudanese, Chinese and Egyptian on eggs cowpea beetle Callosobruchus maculatus.Volatile oils from Sudanese obtained by steam distillation Soxhlet extraction using ethanol correspondingly, whereas oil was bought as a ready-made product.The tested at concentrations 0.01%, 0.1%, 1%, 5% 10%, exposure periods ranging 24-72 hrs.Respective average number laid after lowest concentration were; 5.4, 4.0, 4.1 24...

The efficacy of the fumigant action garlic aqueous ethyl acetate extract (95:5 v/v) from Chinese was tested against adult stage cowpea weevil, Callosobruchus maculatus (F.) (Coleoptera: Bruchidae), under laboratory conditions at Department Crop Protection, Faculty Agriculture, University Khartoum, Shambat, Sudan.Garlic extracts were prepared by 24 hrs soaking powder in water: solution (95:5% v/v).The concentrations 0.1%, 1%, 5% and 10%.The bioassay done plastic cups placed glass chambers...

This study aimed at investigating the effect of extracts offenugreek seeds on feeding and development African melonladybird beetle, Henosepilachna elaterii. (Rossi). Seeds fenugreek(Trigonella foenum-graceum) were extracted by distilled water andorganic solvents (chloroform, acetone ethanol), weretested against melon ladybird beetle under laboratoryconditions. Both aqueous organic showed significant growthregulatory activities, mainly prolonging larval duration. The effectwas clear in late...
