Disease and Pest Control of the Stick Tree
As a unique existence among succulents, the stick tree is deeply loved for its upright trunk and drought-resistant characteristics. However, the seemingly strong stick tree often faces the困扰 of diseases and pests during maintenance. This article will systematically analyze the key points of prevention and treatment from two dimensions: diseases and pests.
Identification and Control of Stick Tree Diseases
(T-J) Leaf Spot Disease Cause Analysis
When the humidity of the maintenance environment exceeds 60% and the lighting is insufficient, fungal diseases are prone to occur. The early stage of (T-J) disease is manifested as brown circular spots, while leaf spot disease shows irregular brown-yellow spots, both of which can cause premature aging and leaf fall.
Triple Play of Disease Control
1. Environmental regulation: Set a drainage layer during the rainy season to maintain the breathability of the matrix. 2. Drug disinfection: Spray with carbendazim 800 times liquid at the early stage of the disease, once a week for 3 weeks. 3. Diseased plant treatment: Timely cut off the diseased branches and incinerate them to block the spread of fungal spores.
Stick Tree Pest Control Strategies
Scale Insect Harm Characteristics
This type of pest often lurks under the epidermis of branches and trunks, causing new buds to be malformed by absorbing sap. During the high-incidence period of pest infestations, white waxy secretions can be seen on the branches and leaves, which can cause sooty mold disease in severe cases.
Biochemical Collaborative Control
• Biocontrol: Introduce Harmonia axyridis to establish ecological balance, releasing 5-8 adult insects per plant. • Physical removal: Wipe the insect bodies with a soft brush dipped in alcohol. • Drug application: Spray the枝干缝隙 with a 1500 times solution of scale insect control.
Through regular inspections, scientific medication, and optimization of the maintenance environment, the resistance of the stick tree to diseases and pests can be effectively improved. It is recommended to check the back of the leaves monthly and do preventive fungicide treatments in spring and autumn to keep the stick tree healthy and growing.
