Control method: For aphids, this pest of holly, the most direct method is to use chemicals to spray and kill them. In terms of chemicals, we can choose 50% pirimicarb wettable powder at 3000 times dilution.
2. Scale insects
Scale insects are an extremely harmful pest, mainly threatening the leaves, branches and fruits of holly. They gather heavily on branches, leaves and fruits, causing leaves to turn yellow, branch tips to wither, tree vigor to decline, and they can also trigger sooty mold.
Control method: For this pest of holly, we can use a pesticide made by mixing 40.7% chlorpyrifos EC and 80% dichlorvos EC at a 1:1 ratio, diluted 1000-1500 times, to spray and kill them.
III. Pest and Disease Control for Holly (Diseases)

2. Scale insects
Scale insects prefer to grow in warm, humid environments. If the growing environment is too dry, scale insects are very likely to appear. They mainly threaten the branches, leaves and fruits of heather, causing leaves to gradually turn yellow, tree vigor to gradually decline, and eventually withering.
Control method: When dealing with this pest of heather, we can use 255 phosmet at 1000 times dilution or 2.5% deltamethrin at 3000 times dilution to spray and kill them directly.
III. Pest and Disease Control for Heather (Diseases)
1. Leaf spot disease
Leaf spot disease, as its name suggests, harms plant leaves. When it occurs, many irregular spots appear on the leaves of heather, and over time small black dots also appear on the spots, greatly affecting its ornamental value.
Control method: When dealing with this disease of heather, we can use 50% carbendazim wettable powder at 500 times dilution to spray the diseased plants. Generally spray once every 7-10 days, and it can recover after 3-4 applications.
2. Rust disease
Rust disease is a type of plant disease caused by parasitic rust fungi, mainly harming the leaves, stems and fruits of heather. When it occurs, many small blister-like spots appear on the affected parts, and in severe cases the spots densely merge into patches, causing the plant to wither and die rapidly due to massive water loss.
Control method: When dealing with this disease of heather, we can use 12.5% diniconazole wettable powder at 2000-3000 times dilution to spray and control the plant. Generally spray once every ten-plus days, and it can recover after 1-2 applications.
