Prevention and Treatment of Pests and Diseases in蟹爪兰 (Disocactus ackermannii)
As an epiphytic plant of the cactus family,蟹爪兰 is loved for its unique plant shape and brilliant flower colors. However, many gardening enthusiasts worry about the ease of infection with pests and diseases during its care. This article will provide answers and solutions through a systematic control plan.
One, Three Key Points for Disease Control
1.1 Key to Preventing Rot Disease
Rot in the succulent stems is a common issue, mainly caused by excessive watering. Suggestions: ① Choose a breathable ceramic pot ② Maintain a slightly acidic substrate (pH 6.0-6.5) ③ Immediately disinfect the cutting tool with alcohol and apply wood ash to the wound upon detecting any lesions
1.2 Solution to Fungal Diseases
(T-J) disease initially appears as brown spots on the leaves, while gray mold disease often breaks out during the plum rain season. Control measures: ① Spray with mancozeb before the rainy season ② Maintain a plant spacing of over 30 cm ③ Rotate the pot weekly to ensure even sunlight
1.3 Prevention of Root Diseases
Root rot disease is often overlooked but can be fatal. Suggestions: ① Soak the roots in warm water at 50℃ for 15 minutes during potting each year ② Use a substrate mix of peat: perlite: vermiculite = 3:1:1 ③ Control watering in winter to keep the soil dry
Two, Comprehensive Pest Management System
2.1 Ecological Control of Scale Insects
When white waxy insects are found: ① Use a toothpick dipped in 75% alcohol to kill them ② Spray neem oil once a month ③ Place sticky traps to monitor the population density
2.2 Comprehensive Control of Red Spider Mites
Easy to occur in high temperatures and dry conditions: ① Mist in the morning and evening to increase humidity ② Wipe the leaves with beer weekly ③ Alternate the use of abamectin and etoxazole
2.3 Biological Control of Aphids
Focus on protection during the bud stage: ① Introduce ladybug larvae ② Hang silver-gray reflective films to repel ③ Spray with sophoraflavescens extract solution
Three, Golden Rules for Daily Maintenance
① Maintain a growth temperature of 18-25℃ during spring and autumn ② Use LED grow lights to maintain 6 hours of sunlight daily ③ Apply phosphorus and potassium fertilizer (N-P-K=5-10-5) monthly during the growing season ④ Choose pitaya as the rootstock for grafting to enhance resistance
By combining scientific prevention with precise treatment, along with controlling temperature and humidity and reasonable fertilization, it is entirely possible to create a healthy ecosystem for蟹爪兰. It is recommended to conduct a systematic check every quarter, address issues early, and keep your蟹爪兰 free from the troubles of pests and diseases.
