Available through authorized OHP distributors, Kalmor is an OMRI-listed, copper hydroxide-based fungicide that is labelled for use on a range of vegetables and herbs grown in greenhouses, shadehouses and nurseries, for control of many problematic fungal and bacterial diseases.
Available in an easy-to-use dry flowable formulation, Kalmor is labelled for control of alternaria, bacterial leaf spot, botrytis, cercospora leaf spot, downy mildews, fire blights, needlecasts, pseudomonas leaf spots, xanthomonas leaf spot, and other diseases.
“Kalmor is a high-quality formulation with smaller particles than other copper-based products,” says OHP technical services manager Dr. Carlos Bográn.
“The smaller the particle, the more copper ions there are in solution which means you need less product to do the same job,” says Dr. Bográn. “Less copper is better for the environment as well.”
Kalmor is effective against resistant strains of certain diseases - making it an ideal choice in an IPM program, adds Dr. Bográn
As with any copper-based products, users should check compatibility with other products before tank mixing. Kalmor should not be tank-mixed with OHP’s Areca fungicide or other aluminum-based products.
