“…Ref. [ 75 ] supported the high efficacy of propiconazole fungicides such as Tilt 25EC, which is particularly effective against leaf rust and yellow rust. Also, propiconazole 25EC demonstrated significant effectiveness in reducing the severity of yellow rust by 80.2% [ 40 ].…”

Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a destructive disease that causes significant yield losses in wheat production worldwide, including in Egypt. The use of biocontrol agents is among the best eco-friendly management strategies to control this disease, as they are more sustainable and environmentally friendly than traditional chemical control methods. In a comparative analysis, antioxidant enzyme activity and various management approaches were compared with two bacterial biocontrol agents, Bacillus subtilis and Pseudomonas putida. This study showed the remarkable efficacy of endophytic bacteria, B. subtilis and P. putida, in mitigating wheat stripe rust infection across three wheat varieties, namely Misr1, Gimmeiza11, and Sids12. B. subtilis exhibited superior performance compared to P. putida, resulting in infection types of 1 and 2.66, respectively, following inoculation. The highest reduction rate was observed with Tilit fungicide (500 ppm), followed by B. subtilis and Salicylic acid (1000 ppm), respectively. Variations in wheat varieties’ response to Pst infection were observed, with Misr1 exhibiting the lowest infection and Sids12 showing high susceptibility. Among the tested inducers, Salicylic acid demonstrated the greatest reduction in disease infection, followed by Indole acetic acid, while Oxalic acid exhibited the lowest decrease. Additionally, the study evaluated the activities of five antioxidant enzymes, including Catalase, Ascorbate peroxidase (APX), glutathione reductase (GR), Superoxide dismutase (SOD), and peroxidase (POX), in the wheat-stripe rust interaction under different integrated management approaches. The wheat variety Misr1 treated with Tilit (500 ppm), B. subtilis, Salicylic acid, Montoro (500 ppm), and P. putida exhibited the highest increase in all enzymatic activities. These findings provide valuable insights into the effectiveness of B. subtilis and P. putida as biocontrol agents for wheat stripe rust control in Egypt, emphasizing their potential role in sustainable, integrated, and environmentally friendly management practices.

“…However, the recent emergence and spread of the Ug99 race and its variants have been reported to cause upto100% damage (Amulaka et al 2013). In addition to rust, PM is an emerging disease that causes considerable yield losses of up to 35% (Sharma et al 1996). Recently, the incidence of PM has increased in several wheat-growing regions worldwide, including India (Vikas et al 2020).…”

Rusts and powdery mildews pose serious threats to wheat and have caused substantial yield losses worldwide. Host resistance is the most economical and sustainable approach for managing such diseases. In this study, an effective leaf rust resistance gene Lr45-derived from Secale cereale L. and a linked stem rust and powdery mildew resistance gene Sr36/Pm6-derived from Triticum timopheevii were successfully pyramided. They were validated into well-adapted Indian wheat cultivars that were already carrying the APR stem rust gene Sr2/ Lr27/Yr30 through marker-assisted backcross selection (MABC) following two parallel backcrossing schemes. Three efficiently linked microsatellite markers, G372 185 (Lr45), , and Xgwm533 (Sr2), were used to confirm introgression of these genes. Lines with resistance genes in each background showed improved agronomic traits in comparison to their recurrent parents. These lines could be used in wheat improvement programs as potentially resistant stocks for leaf, stem rusts and powdery mildew to develop new wheat cultivars.

“…The powdery mildew occurs throughout the year under favorable conditions and it is more severe in late sown kharif crop.A factor limiting breeding progress is that selection for powdery mildew resistance is confined to the cool-dry season on mungbean (Chankaew et al, 2013) [6] . Numerous attempts have been made for the identification of resistant sources against these diseases (Basandrai et al, 1999(Basandrai et al, , 2003(Basandrai et al, , 2011aIqbal et al, 2004;Raje and Rao, 2002;Reddy et al, 1994aReddy et al, , 2001Reddy et al, and 2008 [3,4,5,13,22,23,27,26] of Green gram. Depending upon the temperature and humidity, these diseases spread rapidly in susceptible varieties.In Telangana state, it is cultivated in all most districts but prominently grown in Warangal, Khammam, Medak, Mahaboobunagar, Karimnagar, Nalgonda, Nizamabad and Rangareddy districts.…”

Green gram genotypes/germplasms were evaluated to identify the sources of resistance to leaf spot and powdery mildew diseases. Screening was done under natural field conditions at Regional Agricultural Research Station (RARS), Warangal, Telangana State, India. The experimental material consisted fifty seven AICRP and state twenty one Green gram entries with one check during Kharif-2017 and 19 AICRP and 12 state green gram entries with a check during Rabi-2017, which were screened against the major diseases at RARS, Warangal. Out of one hundred twelve Green gram entries, eight entries viz.,VGG 16-055, VGG 16-036,LGG 607, Pusa 9072,VBN(Gg)2, MGG 385,VGG 15-030 and VGG 16-027 were moderately resistant to Cercospora leaf spot disease; two (TM-96-2 and TARM -1) entries were found highly resistant to powdery mildew Disease. Resistants' can be exploited to develop high yielding varieties of green gram by breeding.
