The product targets more than 20 turf and 30 ornamental fungi, including anthracnose, brown patch, leaf spot, and rhizoctonia.

It is positioned for lawns, landscapes, and greenhouses where a robust, dual-purpose fungicide is desirable.
Spectracide Immunox Fungus Plus
Spectracide Immunox Fungus Plus combines disease control with insect-killing action in a single hose-end concentrate. The dual-action formula helps treat major lawn diseases while also addressing listed lawn-damaging insects upon contact. The product boasts rainproof performance within hours, reducing wash-off concerns and allowing flexible timing for spring and early-summer applications. It is particularly convenient for homeowners who want both fungicidal and insect-control results from one product.
Buying Guide: Key Purchase Considerations
When selecting a lawn fungicide, consider disease variety, coverage area, and the plant safety profile for your grass type. Some products emphasize preventative protection and rapid onset, while others balance curative power with long-lasting protection. Always read the label to confirm compatible turf species and recommended application frequencies.
- Active ingredient and spectrum: Azoxystrobin, myclobutanil, and copper-based fungicides cover different fungi. A broad-spectrum option can simplify selection for mixed disease pressure.
- Application method: Ready-to-spray liquids offer quick use, while granular formulations can provide longer residual protection with slower release. Hose-end concentrates offer convenience for large lawns.
- Coverage and size: Match product coverage to your lawn size to avoid over- or under-application. Consider future uses if you have multiple lawn areas or seasonal needs.
- Safety and organics: Some products are labeled for organic gardening, while others are conventional. If organic practices are important, prioritize copper-based or approved organic formulations.
- Weather and timing: Many products perform best when applied before disease onset or during favorable conditions for fungal growth. Avoid applying during extreme heat or active drought unless label guidance allows it.
- Resistance management: Varying active ingredients across seasons can help reduce resistance. Consider rotating between products with distinct modes of action.
- Environmental impact: Look for products with minimal runoff potential and low non-target effects, especially near non-turf vegetation or waterways.
The selections above balance preventive and curative approaches, offering options for both routine lawn maintenance and disease surges. For homeowners seeking simplicity, a ready-to-spray or hose-end formula can deliver rapid results. For larger or more challenging lawns, a granular or systemic option may provide extended protection and deeper plant uptake. Evaluate your lawn’s disease history, climate, and maintenance routine to choose the best fit.
