Abstract:
Fruitlets and two years of branches of ‘Fuji’ apple were used to establish a rapid method based on conidial germination to evaluate the protective duration of different fungicides against apple white rot in this study.And it used the rapid method to measure the protective duration of 80% mancozeb WP and 80% carbendazim WP.The results showed that conidia appering within 3 days from fruitlets innoculated for 10-15 days were most suitable for testing.The cultivation time was 6 hours at 28℃ in the dark wet environment.Under indoor and field conditions，protective effcets of the two fungicides were descend with the extension of time on fruitlet and branch surface，but the duration of 80% mancozeb WP was longer than 80% carbendazol WP under the same the conditions.Under indoor conditions，protection effect of 80% mancozeb WP was higher than 70% for the 3 days on the surface of fruitlets and two years of branches，was only about 30% after 7 days；under field conditions，protective effcet of 80% mancozeb WP were descend obviously，but the drop speed on the surface of fruitlets was slower on two years of branches significantly.This rapid method based on conidial germination to measure the protective duration of different fungicides against apple white rot could be used in the future.
