Different formulations of the same insecticide often vary considerably in their toxicity to bees. Granular insecticides generally are not hazardous to honey bees. Dust formulations (seldom used today on commercial field crops) are typically more hazardous than emulsifiable concentrates because they adhere to the bee’s body hairs and are carried back to the beehive. Wettable powder and flowable formulations essentially dry to a dust-like form which foragers can carry to the hives. Likewise, microencapsulated insecticides can be collected by foragers …

…Protecting Honey Bees During Corn and Soybean Planting Season
Field crops planting season is underway in the Midwest. Most of the annual crop acreage planted in North America this year will use neonicotinoid treated seed. Neonicotinoids are extremely toxic to honey bees, and recent research has suggested that honey bees that forage near these types of plantings may be at risk. The risk is greatest during the period while crops are being planted. Dr. Christian Krupke and Dr. Greg Hunt (Purdue Extension Entomology) will present an overview of the …
