Scope

Main Technical Content: According to the different types of pests and diseases, they are divided into three categories: major pests and major diseases. 3.1 **Major Pests** There are more than 150 pests that can harm date trees, but only about 20 of them cause significant damage. Among them, green blind bugs, red spiders, and date gall moths pose serious threats to winter dates in Dianzhou. 3.2 **Major Diseases** In the main production areas of winter dates, there are also more than 20 diseases that can harm date trees. Although there are many types of date tree diseases, the following are particularly harmful to Dianzhou winter dates: date rust, scab disease, spot disease, and anthracnose. 4 **Requirements** 4.1 **Pest and Disease Control Management** Pest and disease control is a key aspect of production management. From the budding, leaf unfolding, flowering, fruiting, to fruit ripening stages, various pests and diseases occur and cause harm. The severity and types of pests and diseases are greatly influenced by climate and seasons. In drought years, pests cause more severe damage, especially sucking insects, which can outbreak and cause disasters when environmental conditions are favorable. In rainy years, diseases become severe, affecting flowering, fruit set, and fruit quality and yield, and in severe cases, leading to total crop failure. 4.2 **Control Methods** Dianzhou winter date pest and disease control follows the principle of "prevention-oriented, integrated management", combining plant quarantine, forestry measures, biological control, physical control, manual control, and chemical control. Control methods shift from in-season prevention to dormant-period control, with on-tree control focusing on underground prevention, aiming to detect and control pests early, prevent them from causing disasters, and prevent diseases from causing harm. 4.3 **Plant Quarantine Control** Plant quarantine is a regulatory measure. It involves national
