Doctor
Hello, I am QOSTAL Safaa,
Doctor in Biotechnology and Pathology Vegetale at the Laboratory of Plant, Animal and Agro-Industrial Productions University Ibn Tofail Faculty of Science Kenitra, under the theme: Study of the fungal complex responsible for root rot of cereals and search for some alternative means of control.
Within the framework of a project around phosphates (APPHOS) sponsored by OCP (OCP Foundation, OCP R & D, Polytechnic Mohammed VI University, National Center for Science and Technology Research CNRST, Ministry of Higher Education, Scientific Research and Professional Training of Morocco MESRSFC) ‘Selection and use of Trichiderma spp, for the improvement of phosphate efficiency and control of wheat root rot in Morocco.
Study of the fungal complex responsible for root rot in cereals and search for some alternative means of control.
Study of the tolerance potential of three strains of Plasmopara Viticolà to homologous fungicides in Morocco.
Science of Life branch.
Science of Life and Earth branch.
Physical Science Series option.
Surveys carried out in wheat (hard and soft) and barley fields in April-May 2017 in northwestern Morocco revealed the presence of root rot symptoms in all prospected wheat and barley plots.
In Morocco, saffron is grown in the areas of Taliouine (provine of Taroudante) and Taznakht (province of Ouarzazate). Studies on fungi related to this crop are still very rare. Mycological studies on mycoflora associated with Saffron (Crocus sativus) from the main producing area, located in the Taliouine region was carried out between September (corms for cultivation) and December (soil and roots of saffron plants), 2018. The samples (corms and roots with symptoms) were cut up in fragments and disinfected with alcohol.
This work aims to demonstrate the pathogenicity of 37 isolates of Fusarium species and 4 isolates of Bipolaris sorokiniana on durum wheat (Karim and Amjad varieties)
The biocontrol abilities of Trichoderma isolates isolated from soil and roots collected from adjacent sites to the Khouribga and Benguerir Phosphate mines (Morocco) were tested in vitro by dual culture against different pathogens responsible for root rots in wheat and barley plants (Bipolaris, Curvularia and Fusarium) in the in vitro assays.
Surveys were carried out in wheat (durum wheat and soft wheat) and barley fields in April-May 2017 in northwestern Morocco allowed the isolation of a species of the Curvularia genus from the characteristic necrotic lesions of the root rot of wheat and barley.
Cereal cultivation occupies a preponderant place in Moroccan agriculture; around 5,559,800 ha were sown during the 2016-2017 agricultural campaign more than 60% of the national useful agricultural area, with a production of 97,776,700 Qx (HCP 2019). Wheat (hard and soft) and barley are among the staple foods in Morocco.
Field surveys carried out in wheat (durum and soft) and barley fields in April-May 2017 in North-West Morocco resulted in the isolation of a large number of fungal isolates from typical necrotic lesions characterizing the root rot of these cereals.
Thirty Trichoderma isolates isolated from compost, various crops and soil with roots of adjacent sites to the phosphate mines of Morocco, were tested in vitro for their potential to solubilize phosphorus from phosphate rock. The qualitative assessment of phosphate solubilization by Trichoderma isolates was performed on Modified Pikovskaya Agar (MPA) solid medium.
The study of root mycoflora of wheat and barley revealed the presence of several pathogenic fungi (Bipolaris sorokiniana, Curvularia spicifera, Fusarium culmorum, Fusarium solani, Fusarium nivale, Fusarium poae, Fusarium oxysporum, Fusarium graminearum, Fusarium sp. and Fusarium roseum), able to infect the roots of these cereals thus posing a threat to their culture in Morocco.
With the increasing interest to ensure competitive yields without causing harmful environmental effects, the use of beneficial microorganisms may be an attractive procedure (Singh et al., 2011).
Soil is a substrate rich in chemical elements such as nitrogen, potassium and phosphorus which are a source of nutrients for plants. Phosphorus (P) is of vital importance for metabolic needs, growth and reproduction and therefore for crop production.
