Pest control for red sage

Ligustrum moth

There are many types of moths, including the brown-edged green moth, the beautiful brown moth, the mulberry brown moth, etc. They are common in high temperature seasons and mainly feed on leaves, causing the plants to wither.

Prevention and treatment methods

Once discovered, immediately spray 800 times diluted dichlorodiphenyltrichloroethane crystals or use cypermethrin emulsifiable concentrate to kill.

Scale insects

The main scale insects include white-ringed scale, Japanese wax scale, red wax scale, brown soft wax scale, blowing cotton scale, bran-flake shield scale, snake-eye scale, etc. Their main harm is that they suck the juice of tender stems and young leaves, causing poor plant growth. The disease is more serious in poor ventilation and lighting.

Prevention and treatment methods

Discover the insects in the hatching stage in time. When white bag-like mycelium appears on the leaves, spray them with 2000 times solution of cypermethrin wettable powder in time.

Pay attention to ventilation and cooling during maintenance, and place it in a bright place.

aphid

Aphids mainly feed on the young and tender organs of the plant, damaging stems, leaves, flower buds, etc., affecting the growth and flowering of the plant.

Prevention and treatment methods

When insect pests occur, spray with 2000 times diluted imidacloprid wettable powder.

Rosa trifasciata

The larvae grow in groups and will eat all the tender leaves of the plant, leaving only the main veins, and the plant will not be able to develop normally.

Prevention and treatment methods

If larvae are found, immediately remove the leaves where large numbers of larvae are gathered. And spray 4000 times diluted chlorpyrifos emulsifiable concentrate.

Tetranychus cinnabarinus

Cinnabar spider mites mainly occur in hot and dry seasons. Dense small black spots will appear on the leaves, and the back of the leaves will turn yellow with dead spots.

Prevention and treatment methods

Once it is discovered that the only way to kill it is by spraying with drugs, spray 2000 times diluted Beleba wettable powder 2 to 3 times, once every 3 to 5 days.

Scarab

It mainly feeds on leaves, young shoots and flower buds, affecting the growth and flowering of the plant.

Prevention and treatment methods

Scarab beetles do not move at night, appearing to be in suspended animation, and can be caught and killed in the evening. Use black light to kill.

When there are many insect pests, spray them with 1000 times diluted malathion emulsifiable concentrate.
