Crop protection are the main difficulties that farmers encounter in the agricultural sector. Sunscreen, bird nets, mulch mats, hail protection nets, harvesting nets, and windshields are examples of agrotextiles. The primary reasons for fruit and vegetable crop losses are diseases that develop both before and after harvest. In order to reduce pre- and post-harvest diseases, the purpose of this work
was to assess certain environmentally friendly products. Three organic acids i.e. salicylic, sorbic, and benzoic acids were examined in vitro against the inhibitory zone of Penicillium digitatum, Botrytis cinerea, and Colletotrichum gloeosporioides growth at three concentrations: 0.0, 2.5, and 5.0%. According to our results the inhibition zones for Penicillium digitatum, Botrytis cinerea, and
Colletotrichum gloeosporioides were more than 11.0, 10.0, and 9.0 mm for salicylic, sorbic, and benzoic acids at 5.0%, respectively. Four salts potassium bicarbonate, sodium benzoate, sodium bicarbonate and potassium sorbate at three different concentrations 0.0, 2.5, and 5.0% were examined. The results showed that the inhibition zone of all tested fungi was considerably recorded by all tested
salts. With sodium bicarbonate at 5.0%, the inhibitory zone increased the most, measuring 11.0, 9.0, and 8.0 mm for Penicillium digitatum, Botrytis cinerea, and Colletotrichum gloeosporioides, respectively. The effects of other salts were mild. In vivo tests were used to examine the effects of salicylic acid, benzoic acid, and sodium bicarbonate at a concentration of 5.0% on orange fruit green
mold, apple fruit gray mold, and mango fruit anthracnose. Results indicated that all tested treatments significantly reduced the all tested diseases. At a concentration of 5.0%, salicylic acid and benzoic acid completely suppressed the incidence and severity of every diseases that was examined. Meanwhile, sodium bicarbonate produced a moderate effect.
