Pest Control for Succulents

Common pests

Red Spider

It mainly harms succulents of Apocynaceae, Euphorbiaceae, Asteraceae, Liliaceae and Cactaceae. The insect sucks the juice of young stems and leaves with its mouthparts, causing yellow-brown spots to appear on the damaged stems and leaves or causing them to turn yellow and fall off. The spots remain permanently and do not fade. After an insect infestation occurs, ventilation should be strengthened and low-temperature measures should be taken. 40% dicofol emulsifiable concentrate can be used for spraying at a dilution of 1000-1500 times.

Whitefly

It occurs more frequently in succulents such as Kalanchoe and Sedum in the Crassulaceae family. The insect sucks sap from the back of the leaves, causing the leaves to turn yellow and fall off, and at the same time induces sooty mold, which directly affects the ornamental value of the plants. In the early stage of insect infestation, 40% oxydemeton-methyl emulsifiable concentrate can be sprayed at 1000-2000 times dilution.

aphid

Most succulents that harm the Crassulaceae and Asteraceae families often suck the juice of the young and tender parts of the plants, causing the plants to grow weak. Their secretions also attract ants. In the early stage of damage, spray with 1500 times diluted 80% DDT emulsifiable concentrate.

Scale insects

Long harms plants such as Agave, Haworthia and Cactaceae with compact leaves. The fungus sucks the juice from the stems and leaves, causing the plants to grow poorly and, in severe cases, wither and die. In addition to using a brush to drive away the pests, you can also use 800-1000 times the liquid of Supo Kill Emulsion to spray.

Whitefly

It is the most annoying pest of cactus. It will infest the surface of the stems or leaf-like stems, causing the plants to turn yellow, wither, the nodes to fall off, and induce sooty disease. It can be sprayed with 800 times diluted 25% imine sulfuric acid emulsifiable concentrate or 2000 times diluted 40% cypermethrin emulsifiable concentrate.
