Prevent plant disease spread with quat test strips for pruning shears, greenhouse benches, and trays. Verify 0–1500 ppm quaternary ammonium sanitizer levels for reliable horticulture sanitation.
Keep plants safe with proper quat sanitation. Plant pathogens spread easily through shared tools and greenhouse equipment. From pruning shears to potting benches, quaternary ammonium compounds (quats) are widely used to prevent cross-contamination. Indigo® 0–1500 ppm quat test strips help growers confirm sanitizer concentrations are strong enough to kill pathogens, but safe for plants and workers.
Sanitizing garden tools used around fruits, vegetables, and flowering plants, requires quaternary ammonium chloride (quat) concentrations ranging from 800 to 1500 ppm to effectively eliminate plant pathogens. At these levels, quats are effective bactericidal, fungicidal, and virucidal agents that work both in home gardens and in greenhouses, nurseries, and commercial agriculture.
We've been selling quaternary ammonium (quat) test strips since 2007. Buy best-in class, fully documented Indigo® QAC test strips, 100 strips/pack with a guaranteed 3 year shelf life (dated back from expiration date "yyyy.mm.dd"); see storage requirements in Specifications.
Dip strip & remove for immediate reading at 200-400-750-1000-1500 ppm for quaternary ammonium disinfectant concentration. Read strip results immediately. If you wait the 30 seconds needed for some other strips you will get a reading that is too high.
