What are Neonicotinoids?• A class of insecticides that work on the nicotinic
acetylcholine receptors.Systemic Nerve Poisons
• Examples:– Imidacloprid (Admire Pro, Gaucho, Aeris, etc.)– Thiamethoxam (Centric, Cruiser, Avicta, etc.)– Clothianidin (Belay, Nipsit INSIDE, Poncho)– Acetamiprid (Intruder)

What are they used for?• Seed Treatment: Thrips
• Foliar Spray: Tarnished Plant Bug, Cotton Aphid

Why is it important to know their value?
• European Union uses the Precautionary Principle
• U.S. EPA uses a Risk-Benefit analysis
• Currently, a lot of research focused on the risks of all insecticides, but little research on their benefits
![Page 10: Value of Neonicotinoid Insecticides In MS Cotton](https://reader035.vdocument.in/reader035/viewer/2022081520/5681655a550346895dd7dad9/html5/thumbnails/10.jpg)
Declining Pollinator Health• Several proposed causal mechanisms
– Viral pathogens– Parasitic mites– Pesticides
• Many agrichemical compounds have been detected in honey bee wax and pollen samples of bees managed near agricultural environments.

Tarnished Plant Bug• Key pest of cotton in the Mid-South
• Average 6-7 sprays per acre annually
• Highs range from 10-15
• Often high rates and tank mixes

ObjectiveTo determine the value of neonicotinoid
insecticides in Mid-South cotton
![Page 16: Value of Neonicotinoid Insecticides In MS Cotton](https://reader035.vdocument.in/reader035/viewer/2022081520/5681655a550346895dd7dad9/html5/thumbnails/16.jpg)
Materials and Methods• Treatments:
1) No Neonicotinoids
2) Neonicotinoids
3) Neonicotinoids + Sulfoxaflor
• Planted: May 20, 2013 – Bollgard II
• Harvested: October 11, 2013
![Page 17: Value of Neonicotinoid Insecticides In MS Cotton](https://reader035.vdocument.in/reader035/viewer/2022081520/5681655a550346895dd7dad9/html5/thumbnails/17.jpg)
Materials and Methods• Plots Scouted twice per week
• Insects controlled based on MSU recommendations/thresholds
• All other agronomic practices were the same across treatments (Fertilizer, Herbicides, Defoliant, Irrigation, etc.)
