Pests of Elaeocarpus edulis and their controlThe main diseases of Elaeocarpus are the following: copper green beetle, mole crickets and cutworms, red wax scale, geometrid, and tea bag moth. Copper Green BeetleThe larvae of the copper beetle will damage the roots of the plant and cause the death of the entire plant. The adults will eat the leaves and shoots of the plant, affecting the growth and appearance of the spider. For the adult copper green beetles, you can use pesticides or capture them. In addition, you can take advantage of the phototaxis of the copper green beetles and kill them with light. Mole Crickets and Earth EldersThese two pests mainly harm the roots of the plants. When these two pests appear, you can use DDT to kill them. Ceroplastes rubrumThe red wax scale will suck the sap from the stems and leaves of the plant, and the substances it excretes will cause the plant to suffer from sooty mold and cause the plant to wither. When carrying out prevention and control, it is important to pay attention to the gaps between plants, pay attention to ventilation, and prune branches and leaves in time to destroy them. Another preventive method is to spray the medicine before the nymphs hatch, killing the pests at the root and controlling the number of adults. Teabag mothTeabag moths feed on leaves, causing branch death and affecting the external aesthetics of the tree. The prevention and control measures include manual removal, timely pruning of branches and leaves, and centralized removal of dead and diseased branches. In addition, you can also spray hypertonic avermectin emulsifiable concentrate, cypermethrin emulsifiable concentrate and other agents for drug insecticide. LooperWhen facing looper pests, you should choose a concentrated killing method. You can set up plastic film bags on the tree trunks, or directly spray pesticides. The male moths of the geometrid are phototropic, and this can be used to lure and kill them with light. In addition, the blocking and poisoning method can also be used. |
