What to Do When Viola Leaves Rot
As a beloved ornamental plant, violet leaf rot is a common cultivation challenge. When yellowing or soft rot symptoms appear on the leaves, taking timely scientific measures can effectively save the plant. This article will systematically analyze 5 key treatment plans, from environmental regulation to pest and disease control.
Environmental Regulation Treatment Plan
Strengthen Ventilation Management
Water residue and high humidity are the main causes of leaf rot. It is recommended to ensure 3-4 hours of air circulation daily, move the plant to a ventilated area such as a windowsill, and use a small circulation fan to assist air movement. Especially after watering in summer, it is necessary to open doors and windows to accelerate water evaporation.
Pest and Disease Control System
Comprehensive Control of Downy Mildew
During the high-incidence period in spring, prevent with a 800x solution of Mancozeb every week. Immediately remove diseased leaves at the initial stage of the disease, and alternately use Pyraclostrobin and Metiram for spraying, keeping the leaves dry.
Root and Leaf Treatment for Wilt Disease
Use a 1000x solution of Potassium Permanganate for root irrigation combined with foliar spraying. Soil disinfection with Carbendazim every month, and promptly clean up the surface leaves of the potting soil.
Systematic Control of Mosaic Disease
Focus on controlling vectors such as aphids, hang yellow sticky traps to monitor pest situations. Isolate and care for diseased plants, and use Ningnanmycin combined with amino-oligosaccharides to enhance disease resistance.
Biological Control of Aphids
Release natural enemies such as ladybugs, and use a 25% Imidacloprid 2000x solution in severe cases. Regularly wipe the back of the leaves with garlic extract to prevent egg attachment.
By establishing a preventive maintenance system, the incidence of leaf rot can be reduced by 80%. It is recommended to conduct systematic inspections monthly, combined with a thermometer and hygrometer to monitor environmental data. Remember to promptly remove diseased and damaged parts, rotate pesticides reasonably, and maintain moderate plant spacing to keep the viola in a healthy state at all times.
