Measures for controlling the soft rot caterpillar in succulents

Damage caused by the soft rot caterpillar

The most troublesome aspect of growing succulents is pest infestation, especially the soft rot caterpillar. In early spring and summer, when the incidence of soft rot caterpillar in succulents is high, cacti and succulents are attracted by scale insects, their growth is hindered, the leaf color darkens, and soot blight occurs, causing significant harm.

Causes of the soft rot caterpillar in succulents

Hot and humid weather in summer easily leads to soft rot caterpillar pests. In September every year, the larvae of the soft rot caterpillar usually hide under the bark and then become infectious.

Applying insecticides for the soft rot caterpillar

Chlorantraniliprole, methoxyfenozide, and carbazamides can all be used for the soft rot caterpillar. Resistance can develop from frequent use of chlorantraniliprole and methoxyfenozide, so it is recommended to alternate or rotate the use of other insecticides.

Treatment for the soft rot caterpillar

Chemical insecticides are not good for plants, so homemade remedies can be used to prevent pests at home. Boiling chili peppers in water creates a good remedy with disinfectant properties. Garlic and ginger, which also have disinfectant effects, can be boiled in water and used as remedies.

Treatment for the soft rot caterpillar

Monitoring and forecasting for the soft rot caterpillar should start in July. Insecticide control should be carried out during the peak periods of egg hatching and larval hatching, with spraying best done every 3-4 days and once a week. Available insecticides for the soft rot caterpillar include Lesiben emulsion, Kangyesong emulsion, and Kangjuzhi emulsion.

Preventive measures for the soft rot caterpillar

The insecticide Xijingte suspension mixed with water has good effects. If the late rice crop has entered the stage of panicle differentiation, the appropriate period for control has passed, and no more pesticides need to be sprayed.
