Hello. This is Kkumkkura Jujube. With temperatures rising rapidly recently, the rate of germination and the timing of pest and disease outbreaks are occurring earlier than in previous years in jujube cultivation fields. Accordingly, we have compiled essential management points to check at this time, tailored to both greenhouse and open-field environments. We also introduce the causes and solutions for the recurring leaf tip burn symptoms experienced by apple jujube (king jujube) growers every year.
