Root treatment with oxathiapiprolin, benthiavalicarb or their mixture provides prolonged systemic protection against oomycete foliar pathogens - Fig 13

A-C, Control of basil downy mildew in the field by root treatment with BENT, OXPT or ZE. Two-leaf basil plants growing in multi-cell trays were treated (n = 10) with BENT, OXPT or ZE of 0.01, 0.1 or 1 mg a.i. per plant. Plants were transplanted to the field one day later. Disease scores were taken at 9–23 DAT. A- Disease records as taken at various time intervals after transplantation. Different letters on curves indicate on a significant difference between treatments at α = 0.05 (t-test). B- Area under disease progress curves. C- Season-long protection. D-F, Control of basil downy mildew in the field by root treatment with BENT, OXPT or ZE. Four-leaf plants growing in 250 ml pots (n = 10) were treated with a fungicide and transplanted to the field two days after treatment. Disease scores were taken at 8–20 DAT. D- Disease records as taken at various time intervals after transplantation. Different letters on curves indicate on a significant difference between treatments at α = 0.05 (t-test). E- Area under disease progress curves. F- Season-long protection. H and I, the appearance of the plants at 13 DAT. Note heavy sporulation of P. belbahrii in control plants but no sporulation in plants treated with ZE of 0.01 mg ai per plant.
