Jujube rust is easy to attack when there is more rain and high humidity. The rust of jujube rust which is often closed and low-lying and prone to stagnant water is serious, and defoliation and fruit drop are also serious. Intercropping high stem crops under the trees, poor ventilation and light transmission, early onset and heavy. The onset begins with the lower part of the canopy and the middle, and gradually expands towards the top. Prevention and treatment of the disease should pay attention to proper close planting, trimming the dense branches to facilitate ventilation and light transmission; timely drainage in the rainy season to prevent the orchard from getting too wet; do not grow vegetables and other frequently-irrigated crops between rows. After defoliation, the fallen leaves in the jujube garden are cleaned before being germinated and burned or buried deeply to eliminate the source of the initial infection. In the peak period of rust, diniconazole wettable powder or difenoconazole water dispersible granules may be used.
