3 Best Time for Activity Spore germination Penetration Mycelial growth Blistering Sporulation 3

4 MODE OF ACTION C) Before treatment, the conidia are in chains and the mycelium develop abundantly on the leaf surface. D) After treatment with Buran, the conidia and the mycelium are plasmolyzied and are drying out 4

No differnce observed for ph (p=0.4927) and TA (p=0.8939).

12 2017 Strawberry trials data for sales support Results from fruit grading conducted on 9 of the 24 harvests 13% increased weight of marketable fruit per plant (Control+6L/ha vs 12L/ha; p=0,0304) Increased number of marketable fruit per plant (Control+6L/ha vs 12L/ha; p=0,0491) Increased total fruit weight per plant (Control+6L/ha vs 12L/ha; p=0,0336) Trial was conducted in Florida under a complete conventional plant protection and fertilization program (proportion of fruits with disease symptoms <0,1% at grading). Tivano treatments at the rate of 12L/ha significantly increased the average weight of fruits per plant, the number of large fruit per plant and the marketable yield. A marketable yield increase has also been observed in trials against angular leaf spot in Florida ( and ). 12
