Science and Technology 110 Science and Technology Co., Ltd. Popularization of QQ Group User "Agricultural Medicine and Drug Co., Ltd." Q: Atractylodes leaves appear black necrotic spots after the beginning of autumn, rotten leaves, what is the reason? How to do?
The Chinese Academy of Agricultural Sciences and Plant Protection Institute Zhao Zhanzhou’s expert group replied: In recent days, there were indeed many Atractylodes macrocephala plots. The reason was that the high temperature and strong light irradiation caused damage to the leaves in the previous period. After the beginning of autumn, the temperature dropped. The growth rate of the leaves slows and the symptoms of damage gradually appear. If the leaves in the field are not particularly large, no measures can be taken; if there are more, some foliar fertilizers and fungicides can be sprayed, such as cytokinins or brassinoline or difenoconazole.
