INFLUENCE OF ROW COVER INSIDE THE GREENHOUSE ON STRAWBERRY GROWTH AND INSECT INFESTATION

Floating row covers, DuPont "Lawn and Garden Blanket", which transmits 75 to 80% of the sunlight, were applied on Nov. 21, 1991 over newly transplanted ‘Douglas’ strawberry. The plants were set on raised beds mulched with black plastic, inside an unheated greenhouse located on the Mediterranean coast of Beirut. Fruit number and yield were comparable between row covered and non-covered plants, over the 16 weeks of harvest. The row cover raised soil temperature at 10cm depth by only 1°C, over the non-row covered beds. Mite adult, nymph and egg counts increased significantly with the progress of the season. No other insects showed up to any serious level. Row covers did not affect the mite counts over non-covered plots; however, the acaricide sprays over the last 8 weeks of harvest, significantly reduced the adult, larva and egg counts, over non-sprayed plots.
