Complete Guide to Pest Control for 蛛丝卷绢
Identification of Root Mealybug Infestation Features
This white wax-coated insect, only 2-3mm in size, sucks the sap from the roots. Initially, it manifests as dull leaves, and in severe cases, the entire plant wilts. Checking the potting soil at night may reveal white powdery secretions, which are typical signs of infection.
Implementation of a Three-Pronged Control Strategy
1. Preventive stage: In May and November each year, dilute Abamectin solution at a ratio of 1:1000 and pour it into the roots. 2. Early treatment: Bury granular insecticides (5-8 granules per pot) and combine with bi-weekly灌溉 of Huahushen solution. 3. Environmental control: Maintain a well-ventilated environment in spring and summer, and use red pottery pots to enhance breathability.
Strategies for Dealing with Diseases in 蛛丝卷绢
Analysis of Black Rot Disease Progression
This disease has a 'three-stage deterioration' characteristic: initial browning of the roots, intermediate soft rot of the stems, and final liquefaction of the entire plant. Under high temperature and humidity, the pathogen can spread to the entire plant within 48 hours.
Staged Treatment Plan
• Stage one treatment: Cut off the infected area, apply sulfur powder to the incision, and place it in a vermiculite matrix to grow roots.• Stage two control: Spray with Mancozeb solution (800 times concentration) weekly.• Environmental optimization: Set up a shading net in summer to maintain a day-night temperature difference greater than 8℃.
Through systematic control and the use of particle soil with 40% perlite, the incidence of disease can be significantly reduced. Regularly observing the plant's condition and addressing issues early is key to maintaining the health of 蛛丝卷绢.
