Ever wonder why are snails and slugs so slow? If so, my students and I penned an answer for curious 11 yr old. I'll bet you know all this stuff:

A new Tooker Lab paper https://t.co/CKeM8Rjblw led by @MarionLeGall29 & @mtboucher provides more evidence that planting green with neonic-free corn or soybean seed can help control damage from slugs via a one-two punch of providing an alternative food source and more predators.

ICYMI: our new research paper, led by @elizabethrowen & Kirsten Pearsons @bikebugz, suggests that cover crops can help control insect pests:
Cover crops more effective than insecticides for managing pests, study suggests | Penn State University https://t.co/sy7nH7PmHI

FYI, we have a new paper available on 'Toxicity of clothianidin to common Eastern North American fireflies' article published in #OpenAccess journal @PeerJLife https://t.co/uicYH9d9ch
The paper was led by Dr. Kirsten Pearsons @bikebugz

Congratulations to Dr. Baniszewski @jbaniszewski10 on formally received her PhD over the weekend! Her hat was better than mine.

[John Tooker @jftooker]

Looking forward to working with Tanya and Eric on this! How DO plants decide on the defense responses to deploy??

A nice summary of challenges posed by seed treatments bu @Emily_Unglesbee of DTN

[Emily Unglesbee @Emily_Unglesbee]

Seed treatments are popular and ubiquitous in agriculture.

But a decade of reporting at DTN -- summarized here -- has raised serious concerns about the overuse, efficacy and environmental fate of the pesticides in them.

Here is a really insightful article from @Emily_Unglesbee on challenges posed by insecticides and fungicides coated on seeds:

A new publication with recent PhD grad Kirsten Pearsons @bikebugz explores simplifying effects of neonicotinoid insecticides on food webs. We hope you can find it useful:

A new paper from our lab (MS graduate Sarah Frame) and collaborators shows that neonics leach from crops fields in water mostly in subsurface flow, but their transport and persistence depends on the solubility of the active ingredients. Check it out!

Thanks for the opportunity to present at #MCCC21 with Kari Dunfield @karidunfield and Stuart Grandy @sgrandysoil ; I learned more than I shared!

[Cornell Cover Crops @CropsCover]

#mccc21 John Tooker @jftooker from Penn State showed that insecticides are killing beneficials in the soil, and that reduced tillage plus #covercrops can provide much of the protection that the insecticides are used for. Biology can be even more on our side.

One of the results of my collaboration with David Giron (IRBI, Univ. of Tours, France) has finally seen the light of day. We tackled a big topic, so it took a while. We hope it is useful to folks.

[John Tooker @jftooker]

@woodhaus2 Hi Franz. A blast from your past. Hope all is well with you and yours, including your brother Kurt. It’s been a long time. FYI brother Mo and I are both tesla owners and love them. You’ve help create something amazing. Thanks! John Tooker

[John Tooker @jftooker]

@bycrestfarms @blake_vince You know that, and Blake and I know that but evidence suggests that the broader Ag community does not seem to know that.

[John Tooker @jftooker]

The impossible is possible, Blake! Thanks for demonstrating it.

[Blake Vince @blake_vince]

No fungicide, no insecticide all season including planting. #nongmo

[John Tooker @jftooker]

A great contribution from recent graduate, Dr. Kirsten Pearsons! Neonics and pyrethroids limit decomposer communities, slowing decomposition in ag fields:

[John Tooker @jftooker]

@mgrieshop You’re right but neonics seed treatments are slightly different because a good percentage (ca. 30-40%) of farmers do not know they are using them.
