What do scales do to plants?

Scale insects feed by sucking sap from trees and shrubs through piercing-sucking mouth parts. Sap feeding by scale insects may cause yellowing or wilting of leaves, stunting or unthrifty appearance of the plants, and eventually death of all or part of the plant when infestations are heavy.

What is soft scale?

Soft scales damage plants by extracting plant fluids from the phloem. This can reduce plant growth and cause leaf drop or branch dieback. The most common symptom of soft scale infestation is accumulation of honeydew and sooty mold on or beneath a plant.

What is black scale on plants?

Look on olive trees, citrus or passionfruit vines and you'll probably find black scale. These sucking insects gather on leaves and stems and can quickly build up to the point where they stunt plant growth. ... Honeydew also leads to sooty mould, a black dusty fungus that grows over the leaves and stems.

How do plants prevent scales?

Regular applications of a horticultural oil such as Bonide All-Seasons Horticultural and Dormant Oil will help. Cover all plant surfaces with the oil in an even layer, and all life phases of scales will suffocate. Neem oil is a godsend.

Does dish soap kill scale?

Dawn liquid dish detergent in approximately a 2 percent concentration is a fairly safe alternative to commercial insecticidal soaps formulated to kill insects such as aphids, mites and scale on plants and keep them away.

How do I know if my plants have scales?

Scale almost always appears in clusters. Unlike other insects, they are immobile once they lock themselves into place to pierce the plant and begin feeding on sap. If you see clusters of tiny shell-like bumps on the stems or leaves of a plant, there is a good chance you are looking at a scale.

How do you get rid of soft scales?

The safest effective way to control scale is with a horticultural oil spray. These insecticides contain oil in a form that will mix with water. When mixed and sprayed onto an infested plant, the oil coats the scale insects and clogs their breathing pores.

What is the life cycle of scale insect?

Scale insects have three distinct life stages (egg, immature, adult) and may complete several generations in a single year. Adult females produce eggs beneath the scale covering or in a cottony material, and in many cases spend the cold winter months in this stage.

How do you treat a soft scale?

The most effective coccid soft scale insect control is using neem oil. Neem oil will treat insects and fungal diseases. Systemic insecticides are also very effective against scale insects because they feed on the plant sap.
