Bonide Rose Shield Spray, 16 oz – Insect & Disease Protection for Roses & Ornamentals

Triple-action protection for roses and ornamentals

Enjoy healthier, more vibrant blooms with Bonide Rose Shield Spray. This 16 oz concentrate delivers a balanced blend of pest control and disease defense designed for roses, flowers, and landscaped plants. The formula acts both on contact and systemically, working from within the plant to reduce pest activity while supporting disease resistance in new growth.

What it protects and how it works

• Triple-action protection — contact and systemic insect control plus systemic disease control safeguard leaves and blossoms from within.
• Broad-spectrum coverage — targets common garden pests such as aphids, leafminers, spider mites, ants (some types excluded), and more; also helps prevent diseases like black spot, powdery mildew, rust, scab, and leaf spot.

Where to use

Designed for roses, flower beds, and landscape plants—apply to roses, shrubs, trees, foliage plants, and groundcovers to support ongoing health and color throughout the season. The product is formulated to move within the plant, helping protect both established growth and new shoots.

Application timing and performance

• Insect protection duration — protects for about 30 days after application.
• Disease protection cadence — reapply every 7–14 days as conditions warrant.
• Weather resilience — becomes waterproof within roughly 60 minutes of applying, helping leaves tolerate light rain or irrigation soon after treatment.

How it works in practice

Thiamethoxam is absorbed by the plant and moves through its tissues, providing internal insect control. Difenoconazole acts as both a contact and systemic fungicide, stopping existing diseases and helping prevent new ones from taking hold. This combination supports ongoing plant health across the growing season.

Usage tips and safety

Follow label directions closely for safe use and storage. Apply to thoroughly cover foliage and blooms when plants are dry, and avoid applying during periods of peak heat. Test on a small area if you are applying for the first time to observe any plant response.
