Disease and Pest Control of Epiphyllum Oxypetalum
As an epiphytic cactus with high ornamental value, Epiphyllum oxypetalum often faces threats from diseases and pests during maintenance. This article systematically sorts out the characteristics of three typical diseases, providing a comprehensive solution including physical intervention, chemical control, and environmental regulation to help plant enthusiasts achieve scientific maintenance.
Pest Control System for Epiphyllum Oxypetalum
Comprehensive Control of Scale Insects
This white waxy pest often gathers in leaf axils and the base of flower buds,吸食汁液导致叶片失绿, and its secretion is prone to cause sooty mold. It is recommended to adopt a dual prevention and control strategy: 1. Physical removal: Use a soft-bristle brush or toothpick to clean the pest bodies regularly. 2. Chemical control: Alternate spraying 25% phosphamidon 800 times liquid and 40% supona 1000 times liquid, once every 10 days for 3 consecutive times.
Dynamic Control of Aphids
Special attention should be paid to the back of tender leaves during the growth period of new shoots. If aphids are found to gather, immediately spray 40% dimethoate emulsion 1000 times liquid. It is recommended to use yellow sticky boards for physical trapping, hanging sticky insect boards around the plants can reduce the insect density by more than 60%.
Disease Prevention System for Epiphyllum Oxypetalum
Three-dimensional Control of Rot Disease
This disease has the characteristics of rapid onset and rapid spread, and a three-level defense mechanism needs to be established: • Substrate improvement: Mix珍珠岩:蛭石:腐叶土=3:2:5 to ensure good permeability. • Environmental control: Start dehumidifying equipment when the air humidity is greater than 80% during the rainy season. • Medicament protection: Spray 50% carbendazim 500 times liquid monthly to form a protective film. For infected plants, immediate surgical treatment is required, cut off the diseased part and apply methyl thiophanate powder, strictly control water during the wound healing period.
By establishing a disease and pest monitoring log, recording key data such as temperature, humidity, and medication cycles, the risk of disease onset can be predicted 15 days in advance. It is recommended to conduct a systematic inspection every quarter, focusing on hidden parts such as the back of leaves and the junction of stems, to achieve early detection and early treatment.
