Abstract
Date palm cultivation in Qatar is subject to attack by many fungal diseases
and ýinsects such as Black Scorch (Thielaviopsis paradoxa); Graphiola
leaf spot ýý(Graphiola phoenicis); Leaf spots (Alternaria sp. &
Cladosporium ýsp.); Red Date Palm Weevil (Rhynchophorus ferrugineus);
Fruit stalk ýborer (Oryctes elegans) and Stem borer (Jebusaea
ýhammershmidti). These pests significantly reduce date yield and quality in
ýseveral farms. Five components of Integrated Pest Management (IPM) were used to
ýreduce yield loss. These components were: 1) Using chemical pesticides, 2)
ýAgricultural practices, 3) Plant quarantine regulations, 4) Biological control
and 5) ýPheromone traps. Results revealed that the infestation level was highly
reduced to ýbelow the economic threshold. Additionally, the effect of ecological
and ýagricultural factors predisposing the palm trees to attack by those pests
was also ýstudied.ý
