Indoor Toxicities and Field Control Effects of 10 Fungicides to Botryosphaeria dothidea
The indoor toxicities and field control effects of 10 fungicides against Botryosphaeria dothidea were determined by crossing method and foliar spray method.Carbendazim and flusilazole had higher inhibitory activities to the mycelial growth of Bot-ryosphaeria dothidea, and their EC50 was 0.0429μg/mL and 0.0507μg/mL, respectively.The EC50 of difenoconazole and propi-conazole was 0.1144 μg/mL and 0.1959 μg/mL, separately.The investigations in field and during storage found that the 3000~4000-fold solution of 430 g/L tebuconazole SC, the 1000-fold solution of 250 g/L pyraclostrobin EC, the 4000-fold solution of 400 g/L flusilazole EC, the 1500-fold solution of 10%difenoconazole WG, and the 600-fold solution of 50%carbendazim WP all had a better control effect against Botryosphaeria dothidea, and they were safe to apple trees.
