Abstract: Control of leaf spot and powdery mildew was evaluated at two sites in Central and Northeastern New Brunswick. Fungicides evaluated were; propiconazole (Topas 250E 500ml/ha), myclobutanil (Nova 40W 340g/ha), flusilazol (Nustar 20DF 200g/ha), cyprodinil (Vangard 75 WG 740g/ha) and fenbuconazole (Indar 75 WP 140g/ha). Applications were made on 16, 28 June, 9 July (Trial 1) and 18, 30 June, 13 July (Trial 2). Disease incidence at both locations was trace to low and no significant differences were found between the treatments and the control.
