Buying Guide: Key Purchase Considerations
- Active ingredient: Different fungicides rely on propiconazole, azoxystrobin, or other actives. Consider the spectrum of diseases you face and any resistance concerns.
- Formulation: Hose-end sprays offer convenience; concentrates require mixing. Choose based on your preferred application style and equipment.
- Coverage and labeling: Check square footage coverage and whether the product is labeled for the grass type you maintain.
- Weather resistance: Some products claim rainproof or rainfast features. This impacts how quickly you need to reapply after rain events.
- Tank-mix compatibility: If you already use other lawn products, ensure compatibility to avoid phytotoxicity or reduced efficacy.
- Preventive vs. curative: Some formulas emphasize prevention, while others target active infections. Align with current disease pressure on your lawn.
