LED lighting promising for better light distribution and light as a control

 Translation:

LED lighting promising for better light distribution and light as a control

Most opportunities for LED lighting are in the preliminary application as a control light for better light distribution. This emerged from a meeting of the business platform light on July 7 at the Horticulture. The purpose of the meeting was the latest results from research, both in the floriculture and vegetable cultivation, to share and discuss.

The presentations and discussions with the 40 present researchers, consultants, suppliers and growers, showed that the replacement of SON-T by LED lighting is expected to have a few years away. This by the high costs and too little energy. And while the heat of a SON-T lamp added value, there is no need to replace it with LEDs. On the cost and energy efficiency of the lamp is however working hard by the suppliers.

But there are opportunities to control light and better light distribution over the crop with LEDs. Examples that were discussed were as LED control light in carnation to replace the bulb and LED in a more low-growing tulip. This requires a lot of interest from practice. The price of LED bulbs is still a bottleneck.

Led by as additional exposure with SON-T used between the crops, like tomatoes, is also an added value given. This additional production by the improved light utilization of the crop. The discussion showed that new research is to focus on the above opportunities, but one must closely reflect the practical results that also picked up more easily.

The meeting is with LTO Grow Service, Ministry EL & I Product Board for Horticulture and organized within the framework of the Platform of Light program Greenhouse as Energy Source and is a continuation of previous meetings. This is the innovation and action to significantly reduce CO2 emissions and greatly reduced dependence on fossil energy for the greenhouse in 2020.

Update: Veranda O

Earlier this year Veranda O, a biopesticide, was labeled for commercial greenhouse use for food crops.  Recently, there have been some updates to the label and the product’s efficacy which we want to share with you.
Thielaviopsis (Black Root Rot) is now included as a pathogen controlled by Veranda O. 
Thus, the top three pathogens controlled are:
  • Botrytis
  • Rhizoctonia
  • Thielaviopsis
NOTE: Downy mildew control is minimal to ineffective (Straight from OHP).

Hort Americas is looking for Pest Management Products for Small Growers

Hort Americas realizes that Urban Farms, Commercial Hydroponic Greenhouses and Vertical Farms come in a wide variety of sizes.  But, we also realize that most greenhouses have very similar problems when it comes to managing insects and diseases.

Also, since this is a very technical subject we recommend that you contact us at infohortamericas@gmail.com to learn more about products like:

Veranda O, Floramite, Pylon, Attain TR, Pyganic, Evergreen, Pygnaic, RootShield, Actinovate, Actino-Iron.

Again, many of these products are labeled for use on Veggies, many are Organic, but many are not so carefully read the approved label.  Hort Americas is also working with non-traditional pest management products like UV Light. Check out the video below.

Using Ozone to Treat Biofilm, Algae, and Waterborne Pathogens

Potential contamination of surface and ground water sources from greenhouse runoff poses a challenge to our industry.  Tighter environmental restrictions, regulations, bruised reputations, and of course damage to our environment are all very real results of runoff.  Growers recognize the importance of conserving water and reducing runoff.  It has been estimated that on a per area basis greenhouse vegetable growers that recirculated their irrigation water used half the amount of water compared to non-recirculated operations.  Ornamental operations that did not recirculate their irrigation water used eight times the amount of water compared to their recirculated counterparts. These estimates are both crop and geographically dependent.  The values listed were the result of a study conducted in Canada.  The inescapable fact remains that growers heavily rely on the use of fertilizers and water to produce high quality crops.  Most growers would agree that if they can reuse their irrigation water and therefore maximize their fertilizer investment while also helping our environment the better it is for their company and everyone else.  The challenge of recycling irrigation water is the increased risk of transmitting waterborne plant pathogens. Untreated recirculated water is a looming disaster.  Furthermore, regardless of whether an operation recirculates its irrigation water they will experience biofilm if left untreated.  Biofilm is just that, a thin film of biological material e.g. bacteria, algae, and other potentially harmful and destructive micro-organisms that form on and coat numerous surfaces and can clog emitters.  It is common for growers to use chemical dosing to remove biofilm and pesticide applications to treat plants for diseases.  There is another solution.  Water treatment technologies make it easier and safer for growers to conserve water and protect their crops.  One technology available to growers is ozone.
Ozone has been around a very long time, occurs naturally, and is a strong sanitizing agent.  That smell in the air we so commonly encounter after a rainstorm: ozone.  The word ozone stems from the Greek verb “ozein” meaning “to smell”.  Ozone is made from oxygen.  Elemental oxygen (O2) exists as two atoms of oxygen. Ozone is the triatomic and unstable allotropic form of the gaseous oxygen.  When the bonds of O2 are broken either by UV rays from the sun or the energy from lightning, single oxygen atoms form.  A portion of these split atoms recombine with O2 molecules to form O3.  Ozone works to control algae and pathogens in irrigation water by oxidizing elements of cell walls before penetrating and oxidizing enzymes, proteins, DNA, RNA, and cell membranes.  Ozone has a short residual time in irrigation water yet it is strong enough to remove biofilm.  To produce ozone mechanically, oxygen from the air is converted by using an ozone generator.  The ozone generator uses electrical energy to cause O2 to break apart and reform as ozone.  The resulting ozone is then dissolved in water.  Ozone is often coupled with other technologies which increase its efficacy.  Pre-filtration provides an aid to ozone by removing larger organic particle debris.  The lower the organic load the more likely the ozone molecules will eliminate remaining algae and pathogens.  The required dose of ozone for any sanitation system depends on the intended application.  Destroying biofilm can be done with dissolved ozone residual levels of 0.2 parts per million for as little as 30 minutes.  Algae can be controlled with dissolved ozone residual levels of 0.01 to 0.05 ppm.  Ozone phytotoxicity can occur if residual levels of aqueous ozone exceed 1 ppm.  Therefore, high levels should be avoided.  Gaseous ozone levels as low as 0.075 ppm can reduce plant growth.  Inline monitoring of ozone is possible.  However, inline monitors are costly ($1,500 to $4,000) and require yearly maintenance cost of approximately $200.  Inline monitors can always be added to a system.  Most growers will elect to purchase a sample colorimetric kit.  Ozone is an oxidizer, so it can also be measured using an oxidation-reduction potential meter.  Growers need to recognize that installing an ozone system is a long-term investment.  Ozone sanitation systems are capital intensive.  However, the long term savings on labor and chemical dosing plus environmental friendliness make ozone sanitation an attractive alternative.  One company that understands irrigation sanitation is Pure O Tech, Inc.  
Pure O Tech’s BES-300 (Fig. 1), which stands for Biofilm Elimination System, supplies a concentration of ozone of up to 35 grams per hour and has an operating flow of up to 300 gpm.  The provision of ozone via the BES-300 eliminates and maintains microbial growth that clogs irrigation lines and emitters all the while increasing oxygen levels in the root zone.  The BES-300 offers drop-in installation, convenient service, and replacement parts.  With the BES-300, operations will experience reduced labor and hazardous chemicals are eliminated.  The result is cleaner irrigation tubing, increased production, and higher quality crops.  The BES-300 uses variable ozone injection rate to match the irrigation flow.  Pure O Tech’s design incorporates degassing and metering ozone in the irrigation lines.  Pure O Tech’s knowledge of mixing ozone and water utilizing an ozone generator makes them unique and worth consideration.  For more information on ozone sanitation and Pure O Tech products please contact customerservice@hortamericas.com or call (469) 532-2383.

Veranda O is now available

Veranda™O
High humidity and cool, cloudy conditions are highly conducive to many plant pathogens that cause plant diseases.  Having the necessary tools to combat these diseases is very important for any successful integrated pest management program.  Hort Americas is pleased to announce another weapon in its arsenal against potentially devastating plant pathogens: Introducing Veranda™O from OHP, Inc.  Recently, vegetables (including cucurbits and others), strawberries and more, were added to the Veranda O label.  Plant pathogens controlled are botrytis, rhizoctonia, and other problem pathogens such as alternaria, and powdery mildew.  The mode of action works by inhibiting chitin synthase during cell wall development.  Veranda O should be used in rotation with other fungicides as part of an overall integrated pest management program.
Veranda O is classified as a “biopesticide”, has no cross-resistance to other fungicides, and is soft on beneficial insects.  The product is a water dispersible granule formulation containing 1.81 ounces of active ingredient polyoxin D per pound. The active ingredient polyonxin D, is a natural antibiotic and fermentation product of a soil bacterium.  With a 4-hour REI, Veranda O has a 0 day preharvest interval except grapes which have a 7 day preharvest interval.  Veranda O should be used at 4 to 8 ounces per 100 gallons of water.
