Hi Wondering there are any members using CO2 as a means of pest control. I am really struggling to get any info on this subject. What I have found is this. PLEASE advice. YOUR HELP WILL BE MUCH APPRICATED
Agricultural and biological applications
Plants require carbon dioxide to conduct photosynthesis. Greenhouses may (if of large size, must) enrich their atmospheres with additional CO2 to sustain and increase plant growth.[26][27] A photosynthesis-related drop (by a factor less than two) in carbon dioxide concentration in a greenhouse compartment would kill green plants, or, at least, completely stop their growth. At very high concentrations (100 times atmospheric concentration, or greater), carbon dioxide can be toxic to animal life, so raising the concentration to 10,000 ppm (1%) or higher for several hours will eliminate pests such as whiteflies and spider mites in a greenhouse.[28] Carbon dioxide is used in greenhouses as the main carbon source for Spirulina algae.
In medicine, up to 5% carbon dioxide (130 times atmospheric concentration) is added to oxygen for stimulation of breathing after apnea and to stabilize the O2/CO2 balance in blood.
carbon dioxide (chemical formula CO2) is a naturally occurring chemical compoundcomposed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas atstandard temperature and pressure and exists in Earth's atmosphere in this state, as a trace gas at a concentration of 0.039% by volume.
As part of the carbon cycle known as photosynthesis, plants, algae, and cyanobacteria absorb carbon dioxide, light, and water to produce carbohydrate energy for themselves and oxygen as a waste product.[1] But in darkness photosynthesis cannot occur, and during the resultantrespiration small amounts of carbon dioxide are produced.[2] Carbon dioxide is also produced bycombustion of coal or hydrocarbons, the fermentation of liquids and the breathing of humans and animals.
