There's a plethora of misinformation, marketing, and hear-say related to growing horticultural plants. In this series, we digest replicated scientific data and research shared in popular science magazines (such as GrowerTalks) and share it with you, the listeners. Scientific papers are often behind a 'pay-wall' and riddled with academic jargon. Fortunately for you, both of the hosts of this show have a relatively limited spoken vocabulary and need to speak things out in very simple terms for ...

ACC, or more commonly known as 1-Aminocyclopropane-1-carboxylic acid on the streets, is a precursor to ethylene, the compound most known for its ability to ripen fruit. ACC was not thought to have its own set of functions, but this recent article supports otherwise. A better understanding of plant physiology can lead to a whole new area of plant re…

I've received reports of large migrations of whiteflies recently in the landscape, from Dallas, Austin and even east Texas regions. It's not uncommon to see large clouds of whiteflies when cotton is 'defoliated' in preparation for harvest; however, whiteflies often need some time to get used to their new plant host (acclimation). Changes in endosym…

Increasing levels of CO2 is one of the driving factors for global climate change. This same CO2 also happens to be vital for plant growth via photosynthesis. As a result, fast-growing plants, such as poison ivy, are actually becoming more abundant and more hazardous. https://www.southernliving.com/news/poison-ivy-more-poisonous-bigger-climate-chang…

Potted plants are arguably overwatered in the greenhouse and nursery industry. Over-watering can be considered a waste of water, results in leaching of pesticides and fertilizers, and can promote plant pathogens. In this episode, we discuss a study that uses various sensors to assess plant stress to determine how much watering can be reduced before…

A common assumption is that ornamental plants must be perfectly clean when they hit the retailer. No pests. Nada. This assumption is unrealistic and rather harmful. By making this assumption, we limit our pest management decisions to options that are most likely to kill all the insects: synthetic insecticides. However, how true is it that synthetic…

The cucumber mosaic virus is a plant virus vectored by aphids. The virus can decrease yields, which would ultimately result in the plant produce less progeny. In a natural environment, we would expect high virus pressure to quickly result in selection for virus-resistant plants. However, the virus counteracts the negative impact on plant fertility …

These fungi can help alter plant defense traits against herbivores…
