Leaf rust caused by Puccinia triticina Eriks. is a fungal disease of wheat (Triticum aestivum L.), which causes considerable yield loss. Host resistance is the most effective and economical method to minimize yield losses caused by leaf rust. The current research was planned to evaluate the response of 93 wheat genotypes lines selected from 716 wheat genotypes delivered to Egypt by International Maize and Wheat Improvement Center (CIMMYT). These genotypes were evaluated against leaf rust resistance under field conditions at two locations i.e. Behira governorate (Itay El-Baroud Agricultural Research Station) and Menoufia governorate during three successive growing seasons i.e. 2017/2018, 2018/2019 and 2019/2020. Results of the current study showed that 47 wheat genotypes were resistant and had the lowest values of final rust severity (FRS %), average coefficient of infection (ACI) and area under disease progress curve (AUDPC). Also, these genotypes showed desirable/acceptable relative resistance index (RRI) at the two locations during the three growing seasons of the study. Therefore, we can select these genotypes as resistant lines in the breeding program for the resistance of leaf rust.

Two field experiments were carried out during the two successive summer seasons of 2014 and 2015 at the experimental farm of the Environmental Studies And Research Institute, University of Sadat City to study the effect of some chemical, organic and bio fertilizers on seed yield and its components as well as rust disease infection of Kafer EL-Shaikh cawpea cultivar. seven treatments were used in addition to control treatment.. Results indicate the treatment of 50% NPK +Rhizobia + Homic + Microbin and 50% NPK + Rhizobia + Homic were the best among all tested treatments where both of them gave an average high-yield and some of its components compared with the other treatments in both seasonsAs for rust disease, the low percentage of infection has always been linked to the presence of humic acid and in some cases with the compost, on the other hand, the ratio was high percentage of infection in most cases linked to the existence of chemical fertilizer and sometimes the presence of rhizobia, or both together. The treatment 50% NPK + Rhizobia +Homic+Microbin was the best while it give the lowest percentage of infection under the four periods in the two seasons. The recommended added rates were as follows: 50% NPK. (16.5kg N+ 30 kg P 2 O 5 + 25kg K 2 O) +2kg commercial rhizobia + 4L commercial homic +5L commercial microben / feddan.

The present study tested the antifungal activity of twenty wild plants grown at the desert area of Sadat city, Menoufiya governorate, Egypt against three phytopathogenic fungi (Fusarium oxysporum, Fusarium solani and Rhizoctonia solani). Antifungal activity of plant extracts was performed using poison food technique. Aqueous extracts showed variability in inhibition of mycelial growth at 10%concentration. Among tested extracts Artemisia herb alba, Convolvulus arevensis, Conyza discordis, Deverra tortuosa, Fagonia arabica, Gymnocarpus decandrum, Limonium sinuatum, Mathiola livida, Pulicaria undulata, Rumex vesicarius, and Typha domnegensis were the most effective plants in reducing mycelial growth. Aqueous extract of Artemisia herb alba recorded the highest percent of inhibition in the radial growth of tested fungi that exceeded 45% in case of fusarium oxysporum.

inety wheat promising genotypes were evaluated for their resistance against leaf rust caused by Puccinia triticina under field conditions at Shibin El-Kom and Sadat City during 2014/15 and 2015/16 growing seasons. Evaluation was carried out through disease assessment including final leaf rust severity (FRS), coefficient of infection (CI) and relative resistance index (RRI). Thirty four candidate lines i.e.

The present study was conducted at a private farm in El-Khatateba -Sadat City-Menofyia Governorate location during 2019/2020 and 2020/2021 to evaluate the effect of foliar spraying with some organic fertilizers (green organic magic, green power and compost tea on growth, seed yield and seed quality of three dry beans cultivars (Giza 6, Giza 10 and Nebraska), as well as the impact of those fertilizers on the severity of the three cultivars of rust diseases. The obtained results showed a wide diversity among all tested cultivars in growth, yield and quality traits. All bean studied traits significantly affected by the differences organic fertilizer treatments in both seasons. Giza 6 cv. had the highest number of pods/plant, number of seeds/pods, number of seeds/plant and seed yield/fad in addition to the lowest percentages of disease severity and disease incidence of rust, in both seasons. Nebraska cv expressed the highest number, 100-seed weight as well as seed contents of; moisture, total protein, total carbohydrates, total soluble sugar and total phenolic in both seasons. Bean plants that treated with Green power gave the highest; number of pods/plant, number of seeds/plant, 100-seed weight, seed yield/fad and the highest seed contents of; moisture, total protein, total carbohydrates, total soluble sugar and total phenolic in both seasons. Bean plants that sprayed with Green power recorded the lowest disease severity and disease incidence and this reduction in both severity and incidence associated with the highest efficacy of disease reduction in both seasons. As for the interaction Giza 6 cv that treated with Green power had the highest; number of pods/plant and seed yield/fad in both seasons. Giza 6 cv that sprayed with Green organic magic recorded the lowest disease severity, disease incidence and the highest efficacy of disease reduction in both seasons. Nebraska cv that treated with Green power had the highest seed contents of moisture, total protein, total carbohydrates, total soluble sugar and total phenolic in both seasons. The results confirmed that seed yield/fed significant negative associated with rust disease severity
