Can CO2 Kill Insects and Garden Pests?

Can CO2 Kill Insects and Garden Pests?

For years, agriculturalists have used carbon dioxide to kill insects in sealed vegetable, grain and fruit storage containers. The benefits are obvious: Because CO2 is not a chemical insecticide, it does not leach into the food, making it totally safe for human consumption. But does that mean CO2 can be used to fumigate live plants? While the evidence says “yes”, it isn’t an easy solution. The first problem with using CO2 to fumigate is that to be effective, the CO2 level must be maintained above 40% over 7-15 days in order to kill every type of insect. For example, in...

Measuring Carbon Dioxide in Outdoor Air

Measuring carbon dioxide levels in outdoor air is both a simple and complex exercise. One of the main problems with talking about regulating global CO2 levels is that scientists aren’t all in agreement on how to measure it. At the simplest level, the monthly average global CO2 levels has been measured since 1958 at the Mauna Loa observatory in Hawaii. At Mauna Loa, the remote location, undisturbed air, and minimal influences of human activity and vegetation are ideal for monitoring CO2 levels over time. The data collected at Mauna Loa indicates a continual rise in global CO2 levels from less...

CO2 Important to Large-Scale Poultry Farming

Poultry is the most-consumed meat in both the United States and worldwide. Much of this expansion is due to the growth of large-scale production methods capable of delivering birds – especially chicken - to consumers at relatively low prices. Bulk carbon dioxide has become an integral part of the booming poultry industry. In fact, at virtually every stage of a chicken's life-cycle, CO2 is used to maximize production. CO2Meter has had the opportunity to work with many producers in the industry, and we’ve developed an understanding of how our products are used. • It starts with egg incubation. Using CO2...

Measuring Gases: Diffusion vs. Sampling Method

Many of you have called us to ask about applications that start with the sentence, “How do I…” In every case, the application falls into one of two groups: measuring gas by diffusion or measuring gas by sampling. Knowing the difference can help you decide which method is best for you. Diffusion – Measurement for Environment From indoor air quality to plant growth to personal safety: all of these involve people and areas where gases are diffused in ambient air. In other words, the sensor measures the gas concentrations diffused around it. Since the sensor is physically in the ambient...
