Scope
The main characteristics and occurrence patterns of diseases and pests affecting Pu'er coffee are as follows:
4.1 The Main Diseases of Pu'er Coffee
The main characteristics and occurrence patterns of the primary diseases affecting Pu'er coffee can be found in Appendix A.
4.2 The Main Pests of Pu'er Coffee
The main characteristics and occurrence patterns of the primary pests affecting Pu'er coffee can be found in Appendix B.
5 Principles and Measures for Prevention and Control
5.1 Control Principles
Follow the principle of "prevention first, integrated control." Consider all factors influencing disease and pest occurrences comprehensively based on the ecosystem of the coffee plantation as a whole. Employ agricultural, physical, and biological control methods primarily while scientifically and safely using chemical control technologies and pesticide reduction techniques to minimize pollution from pesticides to agricultural ecosystems and enhance ecological control levels.
5.2 Control Measures
5.2.1 Select strong-adaptive excellent varieties and healthy seedlings; the quality of the seedlings should meet the requirements specified in NY/T 358.
5.2.2 Strengthen cultivation management, apply appropriate density planting, provide suitable shade, fertilize scientifically, prune and shape plants at proper times, and renew them to avoid excessive fruiting that damages tree strength, prevent premature aging; follow the provisions of NY/T 922 for cultivation management.
5.2.3 Conduct field inspections regularly to monitor disease and pest occurrences, understand their occurrence patterns, and take timely control measures based on their severity.
5.2.4 Prioritize physical and biological control methods. For chemical control, apply green food certification according to the provisions of NY/T 393; for organic certification, follow GB/T 19630.
6 Control Measures for Main Diseases
6.1 Coffee Rust Disease
6.1.1 Select the latest rust-resistant varieties that have been certified. The identification of coffee rust disease should be conducted according to the provisions in NY/T 3331.
6.1.2 Choose appropriate planting areas, clear the garden after harvesting to reduce sources of infection; strengthen field management by maintaining good ventilation and light penetration for the plantation and trees.
6.1.3 Use chemical control when necessary. Strengthen surveys according to the method in DB53/T 1198; spray fungicides when lesions reach level 3; options include using a 1000-2000 times dilution of mineral oil or a 180-300 times dilution of stone sulfur.
6.1.4 Prune diseased and infested branches after harvesting, and destroy them by burning.
6.1.5 Biological control: monitor the field, release tube-shaped swollen legs to control low-age larval stages of the bark beetle according to GB/T 27614; use Beauveria bassiana or Metarhizium anisopliae at a 200 times dilution and apply them drop by drop to the trunk's corky areas.
6.1.6 Chemical control: strengthen surveys and monitoring of high-risk areas according to DB53/T 1201; use highly efficient low-toxicity insecticides when necessary, applying them as a dry spray.
6.2 Coffee Bark Beetle
6.2.1 Apply appropriate shade management, density planting, remove wild hosts, protect natural enemies.
6.2.2 Use water + lime powder + salt to treat the trunk, with a ratio of 2:1.2:0.005; this prevents beetles from laying eggs.
6.2.3 Chemical control: use insecticides on areas prone to coffee bark beetle infestation in May or June; options include Beauveria bassiana or Metarhizium anisopliae at a 200 times dilution, applied drop by drop to the trunks of 2-3-year-old young trees.
6.3 Coffee Green Scale Insect
6.3.1 Strengthen cultivation management, prune and shape in time, creating a well-ventilated environment.
6.3.2 Biological control: protect and utilize natural enemies such as red ladybugs, spotted ladybugs, etc., which prey on coffee green scales.
6.3.3 Chemical control: use chemical agents during the peak period of infestation; options include using 200 times dilution of mineral oil or a 180-300 times dilution of lime sulfur to spray leaves and young branches every 7-10 days, repeating the process twice.
