Understanding pest prevention is the first priority, comprehensive management of pest control examples With the acceleration of urbanization, urban greening and landscape construction are receiving increasing attention. Ornamental plants, as an important part of urban greening, not only beautify the environment, but also regulate the climate. The problem of pests and diseases has become a problem in the maintenance of ornamental plants. This article will introduce you in detail the methods of pest control for ornamental plants and help you solve this problem. Understand pests and diseases 1. Diseases: Plant diseases caused by pathogenic microorganisms (fungi, bacteria, viruses, etc.), such as leaf spot disease, root rot, etc.
2. Pests: Plant diseases caused by insects (such as aphids, red spiders, termites, etc.) or other pests, such as aphids, red spiders, etc. Prevention first, comprehensive management 1. Select disease-resistant varieties: When purchasing ornamental plants, varieties with strong disease resistance should be selected to reduce the risk of pests and diseases.
2. Rotation: Implement a rotation system to avoid continuous occurrence of pests and diseases in the same plot.
3. Clean the countryside: Remove sick and disabled bodies in time to reduce the spread of pathogens.
4. Strengthen management: Reasonably fertilize and water, keep the soil loose, and enhance the disease resistance of plants.
5. Biological control: Use natural enemies, microorganisms and other organisms to control pests and diseases and reduce the use of chemical pesticides.
6. Chemical control: When pests and diseases occur seriously, chemical pesticides can be used for prevention and control, but the following points should be noted: (1) Select pesticides with high efficiency, low toxicity and low residue;(2) Use pesticides strictly in accordance with the instructions to avoid excessive use;(3) Use different types of pesticides alternately to delay the resistance of pests and diseases. Example of pest and disease control 1. Leaf spot disease: It can be sprayed with 70% thiophanate-methyl wettable powder at 800 times or 50% carbendazim wettable powder at 600 times for control.
2. Aphids: You can use 10% imidacloprid wettable powder at 2000 times, or 20% pyrethroid pesticides at 1500 times for control.
3. Red spider: It can be sprayed with 20% Miamijing EC at 1500 times or 1.8% avermectin EC at 2000 times.
The prevention and control of ornamental plant pests and diseases is a long-term and complex task. Only through prevention-oriented and comprehensive management methods can the occurrence of pests and diseases be effectively reduced. I hope this article can provide a useful reference for your ornamental plant pests and diseases control.
