All seed used in transplant production, as well as, any transplants brought into the greenhouse should be certified ‘clean’ or disease-free. Important diseases such as Bacterial leaf spot of tomato and pepper can cause major problems in transplant production if introduced in the greenhouse. Bacterial leaf spot of tomato and pepper can be seed-borne and infested seed can be a major source of inoculum in the greenhouse and cause problems in the field later in the growing season. As a rule for any crop, any non-certified or untreated seed should be treated, if applicable, with a Clorox treatment, or hot-water seed treatment, or dusted to help minimize bacterial or damping-off diseases. For more information on seed treatments for specific crops please see Table E-14 on page E45 in Section E of the 2013 New Jersey Commercial Vegetable Production Recommendations Guide.
An updated table for selected fungicides and bactericides labeled for greenhouse use is available in Section E of the 2012 recommendations guide. The table includes a comprehensive list of fungicides and biological agents approved for greenhouse use. Table E-15 can be found on page E46 and E47 of the 2013 New Jersey Commercial Vegetable Production Recommendations Guide.
