دراسة تاثير عدد الرشات بالمبيد الفطري فوليكور لمكافحة مرض البياض الدقيقي في محصول العنب في منطقة الخليل بفلسطين

Abstract EN

The experiment was conducted in Zini cultivar vineyards established in Hebron to study the significance of increasing the number of Folicur applications to control powdery mildew disease.

The study showed that increasing the number of applications more than four sprays was not economic to farmers and did not improve the efficiency of disease control.

Four sprays were enough to reduce the average rate of infection to 1.5% which is below the economic threshold of the disease.
