almond red leaf blotch is the most important fungal disease that is caused by the fungus polystigma amygdalinum. symptoms depending on the cultivar almond trees can be seen almost all year. in this study the effect of 5 fungicides (copper oxychloride  2000 µg/ml, bordofix 2000 µg/ml, mancozeb 200 µg/ml, bordo compound 10000 µg/ml, triforin 300 µg/ml with rep.control) was examined in a randomize...

Red leaf blotch is one of the major fungal foliar diseases affecting almond orchards. High-resolution thermal and hyperspectral airborne imagery was acquired from two flights and compared with concurrent field visual evaluations for disease incidence and severity. Canopy temperature and vegetation indices were calculated from thermal and hyperspectral imagery and analyzed for their ability to d...

Almond red leaf blotch is the most important fungal disease that is caused by the fungus Polystigma amygdalinum. Symptoms depending on the cultivar almond trees can be seen almost all year. In this study the effect of 5 fungicides (Copper oxychloride  2000 µg/ml, Bordofix 2000 µg/ml, Mancozeb 200 µg/ml, Bordo Compound 10000 µg/ml, Triforin 300 µg/ml with rep.control) was examined in a randomize...

Red leaf blotch (RLB) of almond, caused by Polystigma amygdalinum, is an important foliar disease this nut tree in the Mediterranean basin and Middle East regions. In recent years, incidence has increased Spain, corresponding to increases area newly planted orchards use susceptible cultivars. 2009, experimental orchard including 21 almond cultivars was at Les Borges Blanques, Lleida, northeaste...

Red leaf blotch (RLB) of almond, caused by Polystigma amygdalinum, is an important foliar disease this nut tree in the Mediterranean basin and especially Spain. In recent years, control has become a key factor management Spanish almond orchards. The RLB not easy due to intrinsic factors (e.g., long infection latency periods) low number registered fungicides country. From 2015 2019, different fi...

Stagonospora nodorum blotch, caused by Stagonospora nodorum (Berk.) Castellani & E.G. Germano (= Septoria nodorum (Berk.) Berk. in Berk. & Broome, teleomorph: Phaeosphaeria nodorum (E. Müller) Hedjaroude) can cause serious yield and quality losses of wheat (Triticum aestivum L.) in many countries worldwide (3,14,20). Yield losses caused by this disease have been reported as high as 40% in sever...

Grapevine red blotch-associated virus (GRBaV) was isolated from table and wine grapes, as well as rootstocks, affected by red blotch, a recently recognized viral disease. Phylogenetic analyses revealed the clustering of GRBaV isolates two groups (clades) of genetic variants (Krenz et al., 2014, Al Rwahnih et al., 2015). Producing and using a full-length infectious clone of a representative isol...

The almond, which is a member of the Rosaceae family, is the fruit of the almond tree (Prunus dulcis). It has a hard endocarp that contains a seed covered by a rough, brownish skin. Unlike other prunoid fruits, which have an edible mesocarp and an outer skin known as the epicarp, the almond fruit has an epicarp and a mesocarp that are diffi cult to separate and have no nutritional or commercial...
