Great progress for most this week on planting. Extreme rain in the north for the area Thursday hurts. Route 6 3+”.

Biggest issue – beans planted, no herbicide applied- ppo herbicides (Valor/Envive/Trivence) are labeled to be applied no later than 3 days from planting.

All ppo family herbicides can cause seedling injury and stand loss if we experience heavy rain and cool temps following application.

If you have beans planted with no residual applied consider Prefix herbicide (fomesafen(flexstar)+metolacholar(Dual). This has some residual for grasses plus some broadleaves such as Waterhemp. 1qt per acre of Prefix. By far the best performance and cost option.

IF Beans are NOT emerged you can and should add a product like Canopy Blend and/or a brand of metribuzen for additional weed control and resistance management.

Please contact me for any/all questions about herbicides and planting. This remains our main issue with crop success. We simply can’t catch up with gly only tolerant beans if we miss the residual.

Below – proof of concept is the first part of research. The pictures below were taken tonight – 5/4 of beans I planted 3/26.

I placed 1/2 of the beans in a wet paper towel to absorb water for 24 hours before planting inside at room temp and the other half was planted normal/raw treated beans for each planting date.

I am very surprised there is no significant difference in emergence between the two options. Appx 12 hours difference in favor of the moist beans.

Also planted beans April 21 but no emergence as yet.
