مكافحة مرض العفن الكريمي على ثمار الطماطم باستخدام البدائل الطبيعية للمبيدات

Abstract EN

The results of the laboratory experiments showed that the addition of chemical substances, such as calcium chloride, pure sodium, natural sodium chloride, acetic acid, and propolis extract (bee glue) compared with diethane -45 m fungicide to the nutrient medium of dextrose agar leads to the reduction in the mycelium growth of Geotrichum candidum.

In addition, any increase in the concentration of these substances leads to a significant reduction in the disease rate of the creamy mold disease on tomato fruits of Mona’s variety tested at 4°C.

The percentage of effect of this treatment was (93%, 76%, 80%, 74%) respectively, whereas the effect of fungicide was 82%.
