Corn and Cotton Producers’ Prevented Planting Decision

Federal crop insurance programs have a prevented planting provision that can protect producers from the financial losses and risks associated with not being able to plant the intended crop within the desired planting period. Revenue Protection, Revenue Protection with Harvest Price Exclusion, Yield Protection, and Area Risk Protection insurance policies pay indemnities if producers were unable to plant the insured crop by a designated final planting date or within any applicable late planting period due to natural causes, typically drought or excess moisture. This post highlights several components of those provisions and provides a few examples.

The purpose of this post is to highlight a few factors to consider while making the replant decision. Continue reading

Yield loss is most likely if defoliation occurs during the milk stages, with Continue reading
