Buying Guide for Lawn Fungicide to Control Brown Patch
Choosing the best fungicide for brown patch depends on several important factors. Considering these aspects will help ensure effective treatment and sustained lawn health.
Type of Fungicide
- Granular vs. Liquid: Granular fungicides like Scotts DiseaseEx are easy to apply with spreaders, ideal for broad coverage. Liquids or ready-to-spray formulations provide precise application and fast absorption, often preferred for spot treatments.
- Systemic vs. Contact: Systemic fungicides penetrate grass tissue for internal protection, lasting longer even through rain. Contact fungicides protect surfaces but could wash off more easily.
Active Ingredients
- Propiconazole: Effective against many lawn fungi including brown patch; used in professional-grade products.
- Myclobutanil: Offers broad-spectrum control, curative and preventive.
- Azoxystrobin: Moves within the plant for comprehensive disease defense.
- Natural Compounds: For eco-conscious consumers, food-grade ingredients like citric acid provide safer alternatives.
Coverage Area and Application Ease
Consider your lawn size and whether the product covers that area in one treatment. Ready-to-spray options that attach to garden hoses simplify application, while concentrated liquids provide flexibility but require diluting. Make sure the product suits your preferred application method.
Rain Resistance and Longevity
Choosing a fungicide with rainproof or water-resistant properties ensures protection remains effective through irrigation or unexpected rain, minimizing reapplication. Duration of control, such as coverage up to 4 weeks, helps plan treatment schedules.
Environmental and Safety Concerns
If you have pets, children, or pollinators nearby, consider fungicides labeled as pet safe and bee safe. Natural formulations reduce chemical exposure risks, although they may have different efficacy levels or require more frequent application.
Disease Spectrum
Look for products that target multiple common lawn diseases besides brown patch, such as dollar spot, red thread, rust, and powdery mildew. This multipurpose approach offers better overall lawn protection and value.
Mixing Compatibility
If you plan to combine fungicides with other lawn care products, microemulsion concentrates (MEC) like Atticus Gunner offer enhanced mixing stability and compatibility with various tank mix partners.
