The impact of nine medicinal and aromatic plant products as ground-oil-seeds i.e. fenugreek, arugula, coriander, celery and dill; and dried leaf powders i.e. peppermint, rosella, periwinkle and throne apple separately in comparison with oxamyl on M. incognita infecting eggplant cv. Black Long under greenhouse conditions, indicated that all tested materials obviously improved plant growth parameters of eggplant plants and significantly diminished nematode development and reproduction. Fenugreek as ground-oil-seeds application represented the maximum percentage increase values of plant length (54.3%), total plant fresh weight (177%), shoot dry weight (142.7%) and number of leaves/ plant (117.4%) whereas ground-oil-seeds of dill gave the least percentage increase values in this respect. However, peppermint as powder also represented the maximum increase values of ameliorating plant length (53.6%) , total plant fresh weight (158.4%), shoot dry weight (138.8%) and number of leaves / plant (108.7%), respectively, followed by that of rosella and throne apple whereas periwinkle showed the least values of the same plant growth criteria. Oxamyl ranked first and surpassed other tested applications in percentage increase values of the same plant growth criteria, respectively, and in diminishing nematode criteria with the lowest reproduction factor (RF) value of 0.37 vs 4.6 for nematode alone. Fenugreek treatment overwhelmed other tested ground-oil-seeds in suppressing nematode population density (81.1%), root galling (92.8%) and eggmasses number (92.0%), followed by arugula application. However, the least values of the same nematode parameters was achieved by dill ground-oil-seeds treatment. Moreover, peppermint treatment also surpassed other tested dried leaf powders of medicinal and aromatic plants in diminishing final nematode population (80.5%), number of galls (84.0%) and eggmasses (86.7%), followed by rosella powder (78.1, 84 and 84.4%) for the same nematode parameters, respectively. However, periwinkle powder gave the relatively low value of final nematode population density (60.5%) but with high % reduction values of number of galls (80.0%) and eggmasses (82.2%) than of throne apple in the latter two nematode criteria, respectively. Treatments of fenugreek and peppermint products represented the lowest values of RF that amounted to 0.86 and 0.89 vs 4.6 for nematode alone, respectively.

F. verticilliodes (Sacc.) Nirenberg (G) is the major pathogen of maize worldwide causing seedling, stalk and ear rots. Five isolates of F. verticilliodes have ability to infect maize Pioneer cultivar plants. The isolates varied in their infectivity, F. verticilliodes isolate 3 gave the highest stalk rot severity in both 2008 and 2009 growing seasons, followed by isolate 4, while isolate 5 was the lowest pathogenic one. In vitro, the microelements [zinc (Zn), manganese (Mn) and copper (Cu)] reduced linear growth of the pathogen. Manganese exhibited the highest toxic effect followed by zinc while, copper exhibited the lowest toxic effect. The antagonistic effects of 3 P. fluresences isolates on mycelial growth of F. verticilliodes were in the range of 55.14 to 79.82%, P. fluresences isolate (Pf2) considerably more antagonistic than other isolates. Under greenhouse conditions, treatment of maize plants with microelements decreased significantly disease severity. Manganese treatment was more effective than copper and zinc treatments. The biocontrol with P. fluresences (Pf2) provided moderate level of protection when used alone, while combination of Pf2 with microelements treatment significantly improved the biocontrol activity and significantly reduced disease severity compared with microelements alone. Microelements content increased with P. fluresences treatment comparing with control treatment.

The present study was carried out at the experimental farm, faculty of Agriculture, Mansoura University during two seasons (2010 and 2011) to evaluate the host plant (blood orange, limon and mandarin) - scale insect, parlatoria. oleae (Colvee)interactions.
The olive scale, P. oleae Population exhibited three peaks of abundance on blood orange and limon orchards, while, it showed two peaks only on mandarin orchard.
The more favourable host for P.oleae was blood orange followed by Limon then mandarin. However, P. oleae female showed the highest fecundity on blood orange trees and the lowest on mandarin trees. The average number of offspring for p.oleae female was 35.4 ± 4.8, 30.9 ± 5.6 and 18.7 ± 4.2 / female on blood orange, Limon and mandarin leaves, respectively.
Chemical analysis indicated that mandarin leaves had the highest percentage of total protein in comparison with limon and blood orange leaves. On the contrary, the pest exhibited the lowest reproductive rate and population density on mandarin leaves. So, volatile oils produced by the mandarin leaves may play a role in insect biology.
Statistical analysis indicated that there was a positive correlation between the changes of total protein contents and those of P. oleae population density in all tested host plants.

Two experiments were conducted at the experimental Farm at Tag El-Ezz, Dakahlia, Egypt, during 2008/2009 and 2009/2010 to evaluate the productivity, chocolate spot and rust diseases for five faba bean cultivars under two sowing dates and three salicylic acid concentrations. Sowing date November 15th gave the highest values of morphological and yield characters while, gave the lowest values of chocolate spot and rust compared with October 15th sowing date in both seasons. Seed yield/fed. recorded 8.17 and 7.49 ardab**/fed*. for sowing date November 15th and 6.17 and 6.15 ardab/fed. for the sowing date October 15th in both seasons, respectively. Giza 716 produced the highest seed yield/fed. in the second season, but no significant differences were observed between faba bean cultivars in the first season. The maximum reduction in severity of chocolate spot and rust diseases accrued under the application of salicylic acid (SA) at 150 mg/L. at the two sowing dates in both seasons. Whereas, led to marked improvement in morphological characteristics and yield. The interaction between sowing date and faba bean cultivars led to significant increase in plant height, straw yield, seed weight/plant and seed yield in both seasons. The maximum reduction of chocolate spot and rust disease severity was recorded with Giza 716 in November 15th planted under application of SA at 150 mg/L.
The correlation coefficient cleared significant positive correlation between seed yield and each of individual studied characters. Multiple regression analysis indicated that the relative contribution for all characters gave 93.06% from the total variations of yield. Stepwise regression revealed that three out of six variables significantly affected seed yield/plant, these variables were seed weight, number of branches and number of pods per plant.
The present investigation recommends to planting Giza 716 cultivar in November 15th with spraying of SA (150mg/l.) after 50 and 70 days from sowing to decrease the severity of chocolate spot and rust diseases and improve faba bean productivity.

Survey of fungal brood diseases were carried out in four districts of Dakahlia governorate (Mansoura, Metghamer, Metalsil and Bilqas) from September 2009 to August 2011. Two fungal diseases of the honey bee larvae were occurred in all tested districts which were chalkbrood (ascosphaeriosis) (CHB) and stonebrood diseases. CHB disease is the only fungal disease causing a problem in honeybee colonies . It appeared on the honey bee in all apiaries during autumn and winter seasons, however sometimes appears during summer. stonebrooddisease is fungal disease that effects on honey bee larvae before the capped stage. Similarity, it spread in all districts during autumn and winter seasons.

Field experiments were carried out at the experimental farm of Sakha Agricultural Research Station during 2009/10 and 2010/11 seasons. Three levels of mineral nitrogenous fertilizers and/or different treatments of compost tea were evaluated as affecting on insect infestation in sugar beet, as well as fertilizer effect on yield and yield characteristics. Infestation by Pegomia mixta Vill, Scrobipalpa ocellatella Boyd and Cassida vittata Vill were significantly highest at 90 kg N/fed as compared with lower doses (60 or 75 kg N/fed). Compost tea treatments induced lower infestation by the aforementioned insects as compared with the check (control). Compost tea used as soil drench (30 L/fed.), applied 40 days after sowing, followed by foliar application of compost tea at 60, 90 and 120 DAS (20 L/fed) proved to be the best treatment against insect infestations. The combination of the latter treatment with the application of 60 kg N/fed resulted in the lowest infestation of sugar beet insects. In contrast, the highest infestation with pest complex (P. mixta, S. ocellatella and C. vittata) resulted from the application of 90 kg N/fed in plots free from compost tea. Compost tea treatment induced significantly high percentages of sugar, purity, and sugar beet extractability, root yield and sugar yield but produced the lowest levels of sodium, potassium and a-amino nitrogen as compared with plots free from the compost tea. From the current results, it could be recommended to use compost tea, particularly as soil drench (30 L/fed) at 40 days after sowing, followed by foliar spray of compost tea (20 L/fed) at 60, 90 and 120 days after sowing. This application was superior in enhancing sugar beet yield and yield components, as well as in reducing insect infestation. It also confirmed that compost tea can be used as organic substrate additives in plant cultivation and substitute for chemical nitrogen fertilizers.

The study were conducted to monitor and determine the presence organochlorine pesticide residues in raw buffalo’s milk and some milk products. The studied samples were collected from different regions, Sharkia Governorate, Egypt. The effect of heat treatment on pesticide residue in raw buffalo’s milk and butter was also studied. The results showed that the only detected organochlorine pesticide residues in all examined milk samples was p,p’-DDE. Resides of DDE detected in yoghurt were 2.7298±0.1126 ppb, with a mean value of 1.9161±0.0992 ppb., while no residues were detected in cottage cheese samples. The organochlorine pesticide residues detected in butter samples were lindane, heptachlor epoxide and p,p’-DDE with mean values of 7.428±1.667, 3.384±1.583 and 67.063±4.933 ppb on fat basis, respectively. Effect of common heat treatment on p,p’-DDE residues in raw buffalo’s milk treated by pasteurization, boiling and sterilization, were 2.509, 0.932 and 0.2599 ppb on milk basis, respectively with degradation percent of 22.13, 71.16 and 92.8% , respectively. Resides detected in butter samples after heating processing to produce ghee were lindane, heptachlor epoxide and p,p’-DDE with a mean concentration 2.948, 1.935 and 15.609 ppb on fat basis respectively with degradation percent of 79.1, 87.50 and 76.76 %, respectively. We can conclude from the study that, the sterilization of raw milk is the most effective method for reduction of pesticide residues. The butter processing by heat treatment produced ghee (Samna) with marked decrease in organochlorine residue content.
