Cactus Pest Control Comprehensive Guide
Although cacti are drought-resistant and easy to care for, various pests are still key factors affecting their healthy growth. This article systematically sorts out the control strategies for four major types of common pests, combining physical prevention with chemical management to help growers establish a scientific pest control system.
Chewing Pest Control Solutions
Control of Caterpillars and Locusts
During the adult activity period from May to September, apply a 2000-fold solution of bromide ester spray comprehensively, focusing on the coverage of new buds and the junctions of stems. It is recommended to apply the pesticide before the dew dries in the early morning, and combining it with yellow sticky traps can enhance the physical trapping effect.
Radical Treatment for Soil Pests
Soil pests such as grubs and wireworms need to be treated with a 1000-fold solution of phoxim for root irrigation. Clear the surface humus before application, and cover with film to kill for 3 hours after application. Organic cultivation suggests mixing wood ash to improve the soil environment.
Sucking Pest Control System
Comprehensive Management of Red Spider Mites
Maintaining 50%-60% environmental humidity can effectively inhibit the reproduction of red spider mites. In the early stages, alternately use a 1500-fold solution of omethoate and a 1000-fold solution of dicofol, focusing on spraying the pubescent parts of the leaf back. Before the winter dormancy period, thoroughly eradicate the eggs.
Ecological Control of Scale Insects
Use medical alcohol cotton swabs for physical removal of the pests, and immediately prune and burn severely infected branches. Introduce natural enemies such as ladybugs for biological control, avoiding the use of broad-spectrum insecticides that disrupt the ecological balance.
Environmental Prevention and Strengthening Measures
Disinfect the cultivation matrix with carbendazim solution monthly, and isolate newly purchased plants for observation for 15 days. Maintaining a 10°C temperature difference between day and night and ensuring at least 4 hours of direct sunlight per day can significantly enhance the cactus's resistance to pests.
By adopting a strategy of "prevention first, control combined," along with regular inspections and scientific use of pesticides, the occurrence of cactus pests can be effectively controlled. It is recommended to establish a maintenance log to record the pesticide application cycle, adjust the focus of control for different seasons, and achieve dynamic management of pests throughout the year.
