As spring arrives, shifting temperatures and rising humidity create ideal conditions for powdery mildew to develop and spread rapidly, especially inside greenhouse structures.

Identifying Powdery Mildew on Most Ornamentals

• Whitish-gray, talcum-like powdery patches on upper leaf surfaces

• These patches (colonies) often coalesce to completely cover
leaves, stems, and in some cases, the entire plant.

•Sometimes confused with spray residue.

Managing Powdery Mildew and Other Diseases

Besides managing the humidity levels in the production area, maintaining disease control on surfaces, in water and on crops is essential to reducing cross-contamination and development of pathogens.

Pace KleenGrow is a multi-use, EPA registered product that provides safe, effective, broad-spectrum control of water borne pathogens and algae in irrigation systems, plant pathogens on greenhouse crops, and diseases, viruses, and algae on hard surfaces. It offers powerful residual protection (up to 14 days on crops and up to 30 days on hard surfaces) and is a value tool for growers for managing plant diseases such as powdery mildew.

A clean environment, combined with protected crops, leads to healthier, more resilient plants. Use KleenGrow this spring as your season long insurance policy.

KleenGrow is not registered for the control of algae in the state of California

As exhibitors at Indoor Ag-Con 2026, we’re looking forward to hearing Peter Konjoian, sponsored by Pace 49, present Under Pressure: Managing Disease & Pest Threats in High-Tech Vine Crop Production

With a strong background in horticultural education and applied research. Peter previously collaborated with Judy McWhorter, VP Pace Plant Health, on greenhouse and nursery microbial control research. Including work focused on irrigation systems, biofilm management, and plant pathogen control.

At Pace Plant Health, a core principle we emphasize is that three critical target areas must be addressed as part of an effective start clean-stay clean strategy for hard surfaces, irrigation lines, and recirculating water systems. We also believe that a continuous, prevention focused approach reduces the overall cost and complexity of growing healthier crops.

Our PACE ACBD System® (Always Clean Before Disinfecting) is a research-proven protocol designed to optimize cleaning, microbial control and disinfection performance.
By removing mineral buildup and greasy residues first, surfaces are properly prepared for disinfection, helping to reduce
cross-contamination of plant pathogens, thus supporting a cleaner, healthier working and growing environment.
