Reduction infestation percentages of spiny bollworm (SBW), Earias insulana (Boisd.),and pink bollworm (PBW), Pectinophora gossypiella (Saund.),on cotton treated with some chlorpyrifos and cyhalothrin formulations alone or/and mixed with Top Film or Tritone K adjuvants were investigated under field conditions. Adjuvants/insecticides mixtures enhanced the reduction percentages of E. insulana infestation, compared with individually applied insecticides. Mixtures of Top Film with chlorpyrifos or cyhalothrin formulations gave the highest reduction percentages of infestation, where general reduction average ranged between 81% and 89.7%, and between 86.5% and 93.2%, respectively. Moreover, Tritone K mixed with cyhalothrin formulations displayed adequate infestation reduction, as general reduction averages ranged between 80.6% and 88.1%. In general, tank mixing of both adjuvants with cyhalothrin formulations enhanced the efficiency of formulation greater than mixing adjuvants with chlorpyrifos formulations against E. insulana. On the other hand, the infestation percent of P. gossypiella was lower than that of E. insulana in untreated cotton plants. The formulations alone or their mixtures with adjuvants gave good reduction of infestation, where the general reduction averages ranged between 88% and 93.5%, and between 70.6% and 87.1% for formulations/adjuvants mixtures and formulations alone, respectively.

The work aimed to indicate the differences in species and population densities of pests, which were found on the eggplant plantations (cv. Roma) in summer and autumn seasons in Alexandria. The results showed that presence of the red spider mite (Tetranychus urticae), whitefly (Bemisia tabaci), potato tuber moth (Phthorimae opercellula), semi-looper (Autographa spp.), onion thrips (Thrips tabaci) and the predator aphid-lion (Chrysopa vulgaris) in autumn season. While, T.urticae, B. tabaci and Autographa spp. were found in summer. T.urticae gave the highest number in the two seasons, especially in autumn. The general averages () of eggs, nymphs and adults were 85, 57.1 and 38.8 individuals/plant, respectively. The corresponding figures were 47.2, 43.1 and 15.1 in summer. Few numbers of the other-mentioned pests were counted in comparison with T. urticae in the two seasons. Therefore, T. urticae constitutes the major pest on eggplant and increases in autumn due to high temperature and PSD (possible sunshine duration). Therefore, effects of some climatic conditions in the two seasons on presence and numbers of pests were studied. In autumn, the simple correlation analysis indicated that PSD was the most effective on eggs of T. urticae. Also, amount of rain showed significantly negative correlations on T. urticae stages in autumn season. Concerning summer season, PSD had significantly effect on adults of T. urticae. It is evident that some climatic conditions have effects on population dynamics of some pests, and PSD was the most important factor on T. urticae. Also, treatments of abamectin and micronized sulfur induced reduction in eggs, nymphs and adults of T. urticae after 2, 5 and 7 days of application with the highest effect of abamectin after 7 days. Significant differences were noticed between treatments and days post-treatment.

Comparative toxicity of methomyl against two land snails Eobania vermiculata and Theba pisana was investigated. The Michaelis constant(Km) and maximal velocity(Vmax) valuesof E. vermiculata and T. pisana AChE were compared. Finally, the in vivo and in vitro inhibition of E. vermiculata and T. pisana acetylcholinesterase by methomyl was studied. Results revealed that, the median lethal concentrations (LC50s values) of methomyl against T. pisana were 58.85, 18.71 and 3.87 % after 24, 48 and 72hrs post-treatment,respectively. On the other hand, LC50s values of methomyl against E. vermiculata were 2.94, 0.92 and 0.38 % after the same time, respectively. The Km values were 0.098 and 0.042 mM and Vmax values were 0.042 and 0.052 mmole/min for E. vermiculata and T. pisana AChE, respectively. Specific activity of T. pisana AChE is 1.43 times the E. vermiculata AChE specific activity. When T. pisana was exposed to methomyl at concentrations of 375, 750 and 1875 ppm the inhibition percentages of AChE were 88.74, 89.44 and 92.25%, respectively. On the other hand, methomyl revealed inhibition percentages of 42.3, 51.4 and 75.3% of E. vermiculata AChE activity at concentrations of 37.6, 75.2 and 188.0 ppm, respectively. The in vitro studies showed that, the sensitivity of T. pisana AChE (I50 = 1.3 µM) is 4.1 times more than the sensitivity of E. vermiculata AChE (I50 = 5.3 µM) to methomyl.

The present work was carried out during the years of 2009, 2010 and 2011 at the Flower and Ornamental Plants Research Garden, Faculty of Agriculture, Alexandria University to study the effects of various levels of salinity of irrigation water (control= 0.47, 1, 2, 4, 6, 8, 10 and 12 ds/m) on the parameters that affect the landscaping potentials of Santolina chamaecyparissus,L. plants and also surveying the common landscaping uses of it in the green areas of Alexandria city. The obtained results indicated that increasing the level of irrigation water salinity led to significant decrease of all vegetative growth parameters (plant height, plant diameter, stem diameter and number of main branches/plant) and significant reduction in the aesthetic appearance and landscaping uses of plants (growth shape and plant condition), compared with the control plants which were irrigated only with tap water. Santolina chamaecyparissus,L plants showed tolerance to salinity of irrigation water till 8ds/m, and increasing the salinity level above 8 ds/m led to death of the plants after 6 months from starting the salinity treatments. Furthermore, surveying the uses of the plant in the landscaping of green areas showed a wide range of uses i.e. in separate beds, on sloped areas, for edging and shaping beds, drawing and writing on lawns and as herbaceous borders. It can be generally recommended that Santolina chamaecyparissus,L plants can tolerate the salinity of irrigation water up to 8 ds/m and still having high landscaping potentials and a good aesthetic appearance.

The present study was conducted on cotton variety Giza 88 during two consecutive seasons of 2009 and 2010 to evaluate and determine the possible use of each of four fertilization types: bio-fertilizer (Microbin®), Organic, Mineral and bio-+ mineral ones; two foliar nutrients (Greenzit S.P100 & Potasin-F), a bio-pesticide “Radiant” and two plant traps of okra and/or maize in comparison to a standard insecticide – Chlorpyrifos, in an Integrated Pest Management (IPM) program for controlling the pink bollworm, Pectinophora gossypiella (Saunders) & spiny bollworm, Earias insulana (Boisd.). The obtained results indicated that the bio-fertilized cotton plants were somewhat less infested with pink & spiny bollworm, in comparison to the organic, mineral and organic-bio fertilized ones. Spraying of both the foliar nutrients - Potasin- F + Greenzit SP100, the biopesticid- Radiant® and/or the conventional pesticide Chlorpyrifos on the surrounded cotton plants by okra and / or maize plants gave lower means values of pink & spiny bollworm infestation. Also, the encircled cotton plants by okra and / or maize plants without any spraying treatments gave lower significant means of infestation in both the successive seasons of study.

The objective of this study was to utilize milk protein concentrate hydrolysate (MPCH) in special drinks as functional beverages and to study the acceptably of such drinks with fresh fruits and flavors. The milk protein concentrate was hydrolyzed by trypsin at pH 7.5 for 20 h. Protein hydrolysis was evaluated by SDS-PAGE and RP-HPLC. Milk protein was completely hydrolyzed by trypsin after 20 h of incubations as there were no bands observed on the SDS-PAGE and broad peptides were separated by RP-HPLC as a source of bioactive peptides. The bitterness of milk protein hydrolysate by trypsin was eliminated by adding sweeteners (sucrose, fructose and sucralose). The reduction of bitterness was highly observed in fresh strawberry and mango juices when compared to flavored juices. However, the best score of sensory evaluation was in MPCH when it was treated by sucrose, fructose and sucralose without flavor compared to MPCH with strawberry flavor. MPCH that utilized in fresh mango juices and sweetened by sucrose, fructose and sucralose received the highest acceptability scores and lowest bitterness compared to all other treatments.

Two field experiments were conducted at El-Sirw Agriculture Research Station, Experimental Farm, Damietta governorate, Egypt during 2012 and 2013 summer seasons. The present investigation was designed to study the effect of gibberellic acid and potassium applications in improving salinity tolerance of three rice cultivars, namely; Giza 177, Giza 178 and Sakha 101. Data of both seasons revealed that, the three tested rice cultivars were significantly varied in their growth patterns, as well as, grain yield and its attributes. Giza 178 rice cultivar recorded the maximum values of plant height, number of tillers/m2, chlorophyll content, leaf area index, the contents of N, P, K and proline, as well as, grain yield and its attributes; viz, panicle weight and number of filled grains/panicle. However, the lowest values of the abovementioned traits were always shown with Giza 177 rice cultivar. Data, also, showed that, potassium and gibberellic acid applications could partially mitigate the harmful effects of salinity stress on growth and productivity of the three tested rice cultivars.

The agricultural sector is one of the leading sectors, which has a clear role in applying the economic reform policies. The overall objectives of the recent agricultural development strategy in are: to achieve a high standard of living of the rural population, the achievement of social justice, increasing agricultural productivity and support the competitiveness of agricultural products. As the agricultural policy includes a range of programs of construction and reform to ensure the optimal use of resources and achieve a balance between the interests of the individual and the community, leading to the achievement of economic and social well-being, The message of agriculture extension stands as one of the mechanisms to achieve the targets of agricultural development and its various agricultural polices. Subsequently the role of local leaders appears as rural base for the success of the extension work in achieving the objectives of the agriculture policy.
From what mentioned above, we can clearly touch the importance of the main adjective of this study which try to identify the level of knowledge of the local rural leaders about the agricultural policy objectives and their role in its diffusion among the farmers in their communities.
The research was conducted on a random sample of 120 leader, represent 50 percent of the total rural local leaders who agricultural extension agents depend on them for planning and implementation of extension activities. Data were collected using a questionnaire. For analysis and display the results the percentages, the arithmetic mean, the theoretical and actual range, frequency distributions, and correlation coefficient of Pearson were used. The most important results are as follows:
-There was 85% from the respondents have level of knowledge of agricultural policy objectives medium or high, which increases the chances of relying on them as liaison to flow the knowledge that related to the objectives of agricultural policy to farmers.
-More than 50% of the respondents got their knowledge about the objectives of the agricultural policy from agricultural extension agent and agricultural cooperative association.
-84.2% of the respondents, have medium or high level for implementation of the practices that will deploy and achieve the objectives of agricultural policies. This confirms that those leaders are the basic rule to maximize the role of agricultural extension in promoting the goals of agricultural policy and increase the awareness of farmers and urge them to adopt it.
-86.7% from the respondents said that the objectives of agricultural policy had achieved in their villages at low-grade or medium, which opens up very wide field in front of extension efforts supported by the efforts of local rural in order to deploy these objectives and provide educational climate and environmental that assist them to adopt it.
-Results showed that there is a significant correlation relationship between the knowledge level of the respondents (the first dependent variable) and the level of implementation of practices related to the deployment and achieve the objectives of agricultural policy (the second dependent variable) and each of the social position, degree of using communication methods, the opinion of achieving agriculture policy objectives and to what extent these objectives included in the extension activities as independent variables,
