- All equipment, benches, flats, plug trays and floors should be properly cleaned and then disinfested prior to use and efforts need to be taken throughout the transplant production season to minimize potential problems.
- Any weeds in or around the greenhouse structure should be removed prior to and after any production.
- Any transplant brought into the greenhouse from an outside source needs to be certified ‘clean’, as well as visually inspected for potential insects and diseases once it reaches your location.
Therefore, labels need to be followed precisely for different use patterns (i.e., disinfesting flats vs. floors or benches) to ensure proper dilution ratios. Hydrogen dioxide products work best when diluted with water containing little or no organic matter and in water with a neutral pH. There are a number conventional and organic products labeled for disease control during transplant production in the greenhouse.
