Pests

1. Scale insects

Scale insects are one of the more common pests among hoya pests and diseases. They mainly feed on the sap in hoya leaves, piercing deep into the leaves with their mouthparts and gradually sucking it out, which causes hoya to wither due to lack of nutrients.

Aphids are a pest that appears on many plants, and hoya is no exception. They mainly threaten hoya seedlings, gradually sucking the sap from the seedlings, which prevents the seedlings from growing and causes them to die. This shows that among hoya pests and diseases, the harm from aphids is still very great.

Prevention and treatment method: The harmful period for aphids is during the transition between spring and summer each year, so everyone must pay special attention during this time. When dealing with this pest, we can use a 1000x trichlorfon solution for spraying and killing. Generally, three consecutive sprays can completely eliminate this pest.

Diseases

Among hoya pests and diseases, anthracnose is a relatively common disease. In the early stages of the disease, many black spots appear on hoya leaves, and as time goes on they gradually spread, eventually causing the plant to wither and die.

Prevention and treatment method: When controlling this disease, we can use a 70% thiophanate-methyl 1000x solution to spray hoya. Generally, spray once every 7-10 days, and after 2-3 times it can basically recover.

2. Soft rot

The peak period for soft rot is every summer, so everyone must pay extra attention during this time. When the disease occurs, many water-soaked spots appear on hoya leaves, and they spread extremely quickly, eventually causing the plant to rot and die.

Prevention and treatment method: When controlling this disease, you must act promptly. If it drags on too long, it becomes very difficult to cure. During treatment, we can use a 1000x methyl parathion spray to prevent and treat hoya.
