Ep. 10. Murder Hornet ‘Slaughter Phase’ and Plant Guttation
Oct 13 • 30 min
The Asian Giant Hornet is one of the many plagues that’s hit us in 2020; but as fall approaches, it’s thought they will enter the slaughter phase, when they can take out an entire bee hive within hours. Fortunately for us in Texas, recent models suggest…
Ep. 9. Poison Ivy Getting Worse and Beetles Escape Through Frog’s Rear End
Sep 29 • 25 min
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…
Ep. 8. Watering potted poinsettias
Sep 15 • 29 min
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…
Ep. 7. Whiteflies on Poinsettias
Sep 1 • 29 min
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…

We often associated federal crimes with illegal drugs, guns or human trafficking, but rarely do we consider that selling plants and insects can be illegal, especially if imported without a permit. In this episode, we discuss two popular science articles…
Ep. 5. Cucumber Mosaic Virus Increases Plant Fertility
Aug 4 • 30 min
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…
Ep. 4. Impact of Soil Fungi on Milkweed Plants
Jul 21 • 32 min
The soil harbors all kinds of fungi; some beneficial and some detrimental to the health of plants. A specific class of fungi, known as arbuscular mycorrhizal fungi (AMF) form a symbiotic relationship with the roots of plants that’s associated with over…

Ep. 2. Great Basin Bristlecone Pine vs the Pine Killer
Jun 23 • 29 min
The mountain pine beetle is a devastating pest of pine forests in the west coast of North America. The beetle will bore into and kill healthy trees, much like the Emerald Ash Borer that has recently been detected in Texas. In this episode, we explore how…
Ep. 1. Intro & Insecticides Causing Secondary Pest Outbreaks
Jun 9 • 28 min
Learn a bit about the two hosts of the show, Erfan Vafaie and Vikram Baliga, how their aspirations to become medical doctors led to become lowly poor scientists, and how they found their passion for insects sand plants. In this episode, we also digest an…
Intro: Jolly Green Scientists Introduction
May 19 • 0 min
On this show, we’ll digest data from scientific research and popular science magazines (such as GrowerTalks) related to horticultural sciences; whether we’re talking about insects or plant production practices. The two hosts are: Erfan Vafaie, Extension…
