Abstract: Control of leaf spot and powdery mildew was evaluated in a commercial blueberry field in Northeastern New Brunswick. Fungicides evaluated were; propiconazole (Topas 250E 500 ml/ha), myclobutanil (Nova 40W 340 g/ha), azoxystrobin (Quadris Flowable 250 1 L/ha), chlorothalonil (Bravo 500 3.5 L/ha) and sulphur (Flowable Sulphur 52 3.75 L/ha). Fungicide applications were made on 4 and 16 July and disease incidence assessed on 2 August. Disease incidence at both locations was trace to low and no significant differences were found between the treatments and the control.
