It poses a big threat, especially to prized species like the Golden Barrel cactus. Treating cactus rot well is crucial. It keeps these plants healthy and beautiful.

Understanding the signs of rot is the first step in cactus rot treatment. Symptoms include soft, discolored areas on the plant. They may develop into holes if the condition worsens.

Cactus Rot Treatment Strategies

Method 1: Fungicide Application

To treat the rot on your cactus, sprinkle a 70% methomyl wettable powder, or a similar fungicide. Keep sprinkling until the rot is dry. Also, add 2 to 3 grams of a 95% dichlorvos water-soluble powder to the top 0.5 to 1 cm of soil around the base of the cactus. Then, cover it with a thin layer of fine soil or sand. If the soil in the pot appears too dry, water it enough to moisten the fungicide powder. After treating, place the cactus in a cool, dry area. Once a dry scab forms and no signs of disease remain, you can resume normal care routines.

Method 2: Quicklime Treatment

After removing the rotten tissue, apply quicklime to the affected areas to burn off the decay. Do this carefully. Remove the lime and decayed matter as you go. Repeat this two or three times. Afterwards, place the cactus in a cool and well-ventilated area to dry until a hard, dry scab forms.

During the summer, you can also use the heat of the midday sun to aid in this treatment. Apply hot, dry soil or sand to the decayed parts until healthy tissue is visible. After each application, remove the decay, repeating two or three times. Finally, without removing the last application, let the cactus dry. Do this in a cool, ventilated area. Do this until it’s healed. Then, resume normal care once it’s healthy again.

Method 3: For Extensive Rot

If the cactus is extensively rotted or hollow but the core is healthy, remove the decayed flesh. First, detach the cactus from its pot. Wash the diseased areas with a 1% copper sulfate or 0.5% potassium permanganate solution. Do this to disinfect them. If necessary, soak the affected parts in the disinfectant solution for thorough cleaning. Or, soak the cactus in a 500 times diluted solution. It is 50% carbendazim. Do this for two hours. After soaking it, put it in a cool, airy, and dry area. Leave it there until it forms a dry scab and you no longer see any rot. Then, replant the cactus.

These detailed methods provide a full way to manage and treat cactus rot. They will keep your plants healthy and vibrant.

Important Considerations for Cactus Rot Treatment:

1. 1. Disinfect the soil right away if you see any rot in your cactus. Do this, unless the rot is severe. Use Method 1 with dichlorvos powder. This step is crucial. It stops the disease from spreading to healthy parts of the plant or other nearby plants.

   2. Best range: 25°C to 30°C. This range helps cacti stay healthy and grow while cutting disease risk. Keep it above 15°C.

   3. Disinfect New Potting Soil: Before planting, mix a fungicide into the new potting soil. A 95% dichlorvos water-soluble powder works well for this. After planting, do not water at once. Instead, put the pot indoors where humidity is above 60%. This prevents overwatering and the potential for rot.

   4. Seasonal Care Tips:

      • Winter: Ensure the temperature does not drop below 10°C to protect your cactus from cold stress.

      • Ideally, water your plants at noon during the summer. This timing ensures quick drying, stopping water from lingering and causing rot. Also, apply a 1000 times diluted solution of 70% methomyl wettable powder every half month. Apply a 500 times diluted solution of dichlorvos to the roots once. During winter, you only need to do root treatment once or twice. Keep the soil moist to ensure the cactus has enough water without risking rot.
