Diseases and insect pests of rat tail palm and their control
As a unique succulent plant, Rattail Palm is favored by gardening enthusiasts for its hanging shape. However, in actual maintenance, pest and disease problems often bother growers. This article will provide an in-depth analysis of the hazards of common diseases and insects in rat tail palms and scientific prevention and control solutions to help you create healthy plants. The core plan for the prevention and control of rat tail and palm disease spot disease: The killer of stem health This disease initially appears as small brown spots on the stem, which forms irregular depressed patches as the disease develops. According to plant pathology research, a high-humidity environment (humidity>75%) can triple the spread of bacterial spores. The infected site eventually appears soft rot, and in severe cases, the entire plant dies. Three-level defense system 1. Environmental control: Keep the temperature difference between day and night at 8-10℃, and control the relative humidity at 50-60%2. Pharmaceutical prevention and control: Use 65% zinc zeb 600 times solution in the early stage of the disease, spray once a week for 3 weeks 3. Physical isolation: Immediately cut off the diseased stem section, apply plant ash to the incision to disinfect the rat tail and palm pest response strategy Red spider: Invisible destroyer These tiny mites cause the plant to lose green by sucking on stem juice. Under the microscope, it can be seen that the back of the leaves is covered with 0.5mm red insect body. In a dry environment (humidity <40%), the breeding cycle of red spiders can be shortened to 5 days, and special attention should be paid to prevention and control in spring and autumn. Three-dimensional control plan·Biological control: introduction of predatory mites (300 released per square meter)·Chemical treatment: alternating use of 1500 times 40% dimethoate EC and 3000 times 1.8% avermectin·Physical removal: Wash the plant surface with pressurized water mist every week By establishing a three-level management system of "prevention-monitoring-management", the incidence of pests and diseases can be significantly reduced. It is recommended to conduct systematic inspections every month, focusing on stem junctions and new bud points. Combined with environmental regulation and scientific medication, the mouse tail palm can be maintained in optimal viewing condition for 5-8 years.
