Olive leaf spot (OLS), caused by Fusicladium oleagineum, is a significant disease affecting olive orchards, leading to reduced yields and compromising olive tree health. Early and accurate detection of this disease is critical for effective management. This study presents a comprehensive assessment of OLS disease progression in olive orchards by in...

This study investigates the physiological and genetic diversity of Allorhizobium vitisstrains in Morocco, focusing on their ability to produce and utilize opines as sources of carbon, nitrogen,and energy. Using ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF) and specific PCR assays...

Crown gall is a globally recognized bacterial disease caused by Agrobacterium tumefaciens. This bacterium is characterized by its potential to infect a wide range of plants, specifically fruit trees. In Morocco, almond trees (Prunus amygdalus) are among the most heavily affected species by this disease. In our study, all tested bacteria were isolat...

Grapevine (Vitis vinifera L.) is one of the most widespread and economically important fruit crops in the world based on its capacity to produce high yields of quality fruit, hectares cultivated and its ability to grow in a wide range of climates and soils. However, it is greatly exposed to a wide variety of pathogens, affecting production and frui...

Codling moth, Cydia pomonella L., is a major pest of pome fruits and walnuts worldwide. Screening the susceptibility of apple varieties to C. pomonella infestation is an important step to develop a sustainable management program against this pest. Therefore, the present study aimed to explore potential correlations between pest damage and several p...

Olive leaf spot (OLS), also called olive scab and peacock eye, caused by Fusicladium oleagineum, is a major disease that causes significant damage to olive trees. However, we still lack information about how cultivar and environmental factors influence disease development. In this study, evaluation of the incidence and severity on twenty olive cult...

This study aims to investigate the yield, chemical composition and inhibitory effect of four essential oils of eucalyptus collected from Morocco on the pathogenic Allorhizobium vitis S4 causal agent of the crown gall of grapevine. The identification of the constituents of essential oils was performed by GC-MS analysis and the antibacterial activity...

Precision Agriculture (PA) is a management strategy based on Information and Communication Technologies (ICT) used to assist management decisions with the aim to increase productivity, to reduce labor time and inputs needed, to improve benefits and to protect the environment. Techniques related to PA were initially used to monitor status of annual...

This work investigated the effects of sustained deficit irrigation (SDI) on yield components and fruit physico-biochemical proprieties of two pomegranate cultivars, ‘Sefri’ and ‘Wonderful’ 21 trees each, in Sais plain (northern Morocco) over two consecutive seasons (2018–2019). Irrigation treatments consisted of a control, irrigation applied to ful...

Conservation and use of well-characterized olive (Olea europaea L.) genetic resources are the key to future olive improvement and sustainable production. Yet, authentication of plant materials in ex-situ olive collections throughout the world has received little attention. Here we characterized 95 accessions, from a collection maintained in the exp...

Stored grains are threatened by several insects, leading to losses in quality and quantity. Several studies have revealed the risks of using chemicals that can cause serious health problems for humans. It is in this perspective that the objective of our work should be seen: It was to assess the effect of the essential oil and leaf powder of Mentha...

Cydia pomonella (L.) is a worldwide dreadful pest in apple fruit production. In Morocco, where high temperatures are prevailing in a growing season, sexual traps demonstrate a massive flight of codling moth leading to an intensive chemical control. In Morocco, data concerning its life cycle are imprecise. Thus, its voltinism and the impact of tempe...

The codling moth, Cydia pomonella (L.), is the key pest of apple production worldwide. In Morocco, there is a sustainable presence of codling moth causing considerable damage in apple orchards despite frequent applications of broad spectrum insecticides. For 12 years, sexual trapping and chemical control were performed and the development of the co...

Disease symptoms in potato plants infected with Candidatus Liberibacter solanacearum and Phytoplasmas from the aster yellows group usually include upward rolling of the apical leaves often associated with secondary bud proliferation, leaf reddish discoloration, premature senescence, malformed or shortened internodes, swollen nodes, aerial tubers. I...
