Replant decisions should be based on strong evidence that the returns to replanting will not only cover replant costs, but also net enough to make it worth the effort.

A study published in the journal Weed Science found cotton yield loss was reduced from 67% to under 30% when weed establishment was delayed until 6 weeks after crop planting.

Researchers found wheat that's resistant to Fusarium Head Blight has specialized and protective cell walls, which may help produce disease-resistant varieties of durum wheat.

Some places have received significant rainfall over the summer and the last week, causing soil moisture to be high in some areas. Soil moisture content can lead to the threat for soil compaction.

New closing-wheel options means that no-tillers may not need to wait for optimal conditions to no-till corn.

Jeff Housman, Mycogen Seeds customer agronomist, advises growers to consider all factors before deciding to replant to determine whether the yield advantage of a replanted field will offset the added cost and the lower yield potential of the first planting.
