Experiences and Recommendations for Cold Protection Sprays???

[huertasurbanas]

Hello all,

I hope this message finds you well. I was curious to know if any of you have used cold protection sprays in your tropical fruit trees and what your experiences have been.

I would love to hear your thoughts on their effectiveness and any recommendations you may have for a specific product.

Thank you in advance for your insights and sharing your knowledge.

Hi again, so nobody ever used those products?

Never seen this stuff before. I think the concept is good but do the work? Time for me to do some research. This could be a game changer.

Fun fact! One of the first GMOs was a spray created that would apply bacteria to frost sensitive plants that would out compete the bacteria that causes frost damage! I believe this was done in Davis, California on grapes.

Amazing info!

Lets keep in touch sharing the experiences here: I will buy some of them and try...

they need to make biodegradeable & safe aerogel, they already have sprayable aerogel. It really is only a matter of time

Today we started the experiment!








We protected: Psidum guajava,  Jambolán, Jua do jequitinhonha, Naranjilla do cipó, Inga marginata and Tamarillo.












We will see if, by september, they did well with our -4 or -5ºC frosts... I am afraid we will have some problems...

Making a similar protector to Wilt-Pruf for frost using beta-pinene and vegetable oils can be an interesting home experiment! Here is a step-by-step procedure:

Ingredients:

• Beta-pinene (400 ml). Bought as mentioned in a free market.
• Olive or coconut oil (600 ml). Vegetable oils will provide softness and waterproof properties.
• Emulsifier (10 ml). Needed to emulsify the oil and pinene, such as liquid soap, caprylic and capric triglycerides (Miglyol) or polysorbate 80.
• Mixer (hand whisk, magnetic stirrer).

Procedure:

Heat the oil mixture (olive or coconut) and emulsifier at 50-60oC with stirring until a homogeneous emulsion is obtained. This would be the oily component.

Heat beta-pinene to 30-40oC to soften it and facilitate its emulsion. If it is not heated well, it will be difficult to emulsify with the oil.

Pour the hot oily component over hot pinene and beat strongly with a hand whisk or magnetic stirrer until an oily and milky emulsion is obtained.

Continue stirring as it cools to ensure a homogeneous emulsion. It must form a stable emulsion, not separate into layers.

Allow the emulsion to cool completely. It should have a thick and creamy consistency. If it is too fluid, add more pinene.

Store the emulsion in an airtight container. It will be the frost protector, ready to apply to fruit trees before frosts.

The formed emulsion will protect plants from cold by forming a protective film. Pinene will help repel water and form a thermal barrier. Oils will provide hydrophobic and waterproof properties.
