How to deal with insects in plum bonsai
As the first of the four traditional bonsai masters, Plum Blossom is deeply loved by flower friends for its proud charm. When mucus is found on branches or holes in leaves, it often means that pests have quietly occurred. This paper will systematically analyze the plum pest control plan from emergency response and prevention systems to pest identification. 1. Emergency treatment plan for pests 1.1 The golden treatment period for pests was found within 24 hours after precise de-pest control operation: the aphids were sprayed with 10% imidacloprid solution (diluted 1:800); the scale insects were sprayed with 50% fentrone EC (1:1000) to focus on spraying branches and branches; Red Spider recommends alternating use of 25% Bereba and 20% Mezaryl to avoid drug resistance. 1.2 For deep soil treatment and soil replacement, 1/3 of the protective soil needs to be retained, and the new soil needs to be disinfected at high temperature (baked at 120℃ for 30 minutes). Special attention should be paid to cleaning up insect pupae in the gravel on the floor of the basin. It is recommended to use 3% phoxim granules for soil pre-embedding treatment. 1.3 Environmental disinfection measures Use 75% alcohol to wipe the surface of the basin and spray broad-spectrum pesticides simultaneously on plants within 2 meters around. pruned pest and insect branches need to be sealed and burned. 2. Scientific Prevention System 2.1 Environmental management practices maintain daytime ventilation for more than 4 hours and humidity control at 60%-70%. Phosphorus and potassium compound fertilizer (N-P-K=5-10-10) is applied every month in spring and autumn to enhance resistance, and no fertilizer is used in summer. 2.2 Pharmaceutical prevention cycle 3-5: spray matrine biological agents every 15 days; June-8: hang yellow sticky insect boards to monitor insect population density; September-November: coat trunks with white (quicklime: sulfur: salt =5:1:0.5). 2.3 Establish a maintenance log for daily maintenance points, and inspect three key parts of leaf backs, tender tips, and basin soil every week. Newly purchased plants need to be isolated and observed for 15 days. 3. Pest identification map How to deal with plum bonsai insects 3.1 Peach pink aphids occur frequently from April to June, gathering young tips to suck juice. In addition to chemical control, ladybugs can be introduced for biological control. 3.2 The May incubation period of the Japanese turtle wax scale nymph is a key control window. It is recommended to use 40% quick-cull emulsifiable concentrate (1:1500) with a toothbrush for physical removal. 3.3 Tetranychus cinnabaris occurs easily when dry at high temperatures, and red bodies can be seen on the back of the leaves. It is recommended to spray 43% biphenylhydrazinate SC (1:2000) in the morning. 3.4 During the larvae stage of the yellow thorn moth (June to August), it is active at night. In addition to chemical control, mint can be planted around to repel adults.
By establishing a three-dimensional system of "prevention-monitoring-management", coupled with precise identification and scientific medication, existing pests can be effectively controlled, and a long-term protection mechanism can also be built. It is recommended that flower friends conduct systematic inspections every quarter and collect this pest map for timely comparison and processing.
