Greenhouse Sanitation Important for Disease Management in Transplant Production

Proper greenhouse sanitation is important for healthy, disease-free vegetable transplant production.

Efforts need to be made to keep transplant production greenhouses free of unnecessary plant debris and weeds which may harbor insect pests and disease. Efforts need to be taken throughout the transplant production season to minimize potential problems.

  • All equipment, benches, flats, plug trays and floors should be properly cleaned and then disinfested prior to use.
  • Any weeds in or around the greenhouse structure should be removed prior to 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.

Remember, disinfestants, such as Clorox, Green-Shield, or hydrogen dioxide products (Zerotol – for commercial greenhouses, garden centers and Oxidate – commercial greenhouse and field), kill only what they come into direct contact with so thorough coverage and/or soaking is necessary. The labels do not specify time intervals for specific uses, only to state that surfaces be ‘thoroughly wetted’. 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.

 

Take a quick survey to help with Field Equipment Sanitation Research!

In a Specialty Crop Research Initiative (SCRI) grant designed to guide future solution and resources centered around field equipment sanitation, collaborative team comprising pathologists, weed scientists, agronomists, and experts in agricultural equipment sanitation has crafted a questionnaire. This questionnaire is designed to gather growers’ input on their current practices and determine the necessity for implementing new ones.

The research will develop a more comprehensive understanding of the challenges associated with field equipment sanitation and work toward developing solutions that are effective, implementable and sustainable.

To introduce the survey and forthcoming research effort, Dr. Matt Grieshop, lead PI on this project indicates that “We are a group of agricultural research and extension professionals from across the United States that are curious about grower and agricultural professional perceptions about the importance of field equipment sanitation to mitigate the spread of organisms that pose human health, weed, plant pathogen or other risks.

Agricultural field equipment includes tillage implements, tractors, harvesters, cultivation equipment, trucks, trailers, sprayers, mowers, or any other piece of equipment that is shared across fields.

This information will be solely used to help frame future research questions and outreach activities.  It will not be published or distributed in any form. Answering should take 5 minutes or less and is completely voluntary and anonymous.

Your participation is invaluable to future developments in the industry regarding food safety and equipment sanitation. We need more inputs from New Jersey specialty crops growers so that they have a say on the direction that field equipment sanitation research will take in the future!

Have A Say in Field Equipment Sanitation Research!

In an initiative to guide future solution and resources, the Specialty Crop Research Initiative (SCRI) has designed the Sanitation of Agricultural Field Equipment Questionnaire to begin the research process centered around field equipment sanitation.

The research will develop a more comprehensive understanding of the challenges associated with field equipment sanitation and work toward developing solutions that are effective, implementable and sustainable.

To introduce the survey and forthcoming research effort, Dr. Matt Grieshop Director at The Grimm Family Center for Organic Production and Research College of Agriculture, Food and Environmental Sciences Cal Poly, San Luis Obispo says,

Virtual Pesticide Recertification Credit Series – Horticulture 3x Sessions

Sessions hosted by Tim Waller and Bill Errickson – through RCE of Cumberland County

Individual Sessions – October 13th (Th), 20th (Th), 26th (W) 6-7:00pm (Login @ 5:30pm)

Please join us as we discuss topics applicable to all horticulture applicators – the classes of chemistries we use, which to use under various circumstances, and safe handling thereof. These sessions are valuable to our general understanding of IPM tactics via a deeper understanding of the tools available to us.

Disinfection of Surfaces for Prevention of COVID-19 Spread – Use Caution

Cleaning supplies

The chemical concentrations for the disinfection of high touch surfaces in retail markets during the COVID-19 pandemic are higher than we normally recommend. This concentration is for the disinfection of hard non-porous surfaces and is not for use on produce. Care must be taken to ensure the safety of yourself and your workers when using this concentration. Typical concentrations of bleach for sanitizing surfaces is 150 PPM, the disinfection recommended 1/3 cup bleach to 1 gallon of water is 1000 PPM. This concentration can be caustic to skin, airways, and produce.  Take the following precautions:

1. Clean the surface with detergent removing all visible debris and with a clean water rinse.
2. Conduct mixing in a well-ventilated area and increase ventilation when possible in areas of use, wear rubber gloves to protect skin from contact with the bleach and bleach solution.
-If skin comes in contact with the bleach or bleach solution rinse with water, if irritation continues call a doctor.
-If the bleach or bleach solution comes into contact with the eyes rinse with water for 15 minutes, if irritation continues call a doctor.
5. Chlorine PPM measurement strips typically used in packing houses do not go up to 1000 PPM.
-1000 PPM test strips are available online through Granger, Amazon, and restaurant supply stores.
-Test strips must be for FREE chlorine, not total chlorine.
-Test strips have expiration dates, make sure yours are not expired.
6. Follow bleach label instructions for contact time requirement. This is the amount of time your surface needs to stay wet with the bleach solution to ensure efficacy and is usually 1 minute or more.
7. Use containers of bleach that have been opened no longer than 30 days to ensure proper concentration.
8. Mixed concentrations of bleach should be stored at cool temperatures and away from direct light, used within a few days and retested for PPM prior to each use to ensure correct concentration.
9. Do not mix bleach with any other cleanser!
