PerCarb is a contact fungicide/bactericide used to control plant pathogenic diseases on field crops, tree crops, berries, small fruits, vine crops, or crops grown in similar settings. The active ingredient is Sodium Carbonate Peroxyhydroxide (containing 75.00% Sodium Carbonate Peroxyhydroxide, which provides 67.20% Hydrogen Peroxide by weight). It works as a strong oxidizing agent to control diseases such as powdery mildew, leaf spots, and various bacterial infections. It is applied as a foliar spray. For best results, ensure thorough coverage of the plant surfaces. Note that this product is highly toxic to bees; do not apply to blooming crops or weeds where bees are active. It is also important to avoid application during amphibian breeding seasons. When handling, use appropriate PPE, including long-sleeved shirts, long pants, and shoes. If clothing becomes contaminated, wash it separately from other laundry. Do not mix with acidic pH solutions, as this may cause loss of effectiveness. Always check compatibility with other pesticides, fertilizers, or fungicides before mixing. This product is subject to Worker Protection Standard requirements.
