Last fall’s wet harvest conditions exposed the soybean seed crop to two key diseases. Phomopsis seed decay (diaporthe longicolla) attacks soybean seeds that are shriveled or have a cracked seed coat, often appearing as a chalky white covering on the seed.
Herbicide resistance continues to become an ever more challenging aspect of crop production. Currently, fifteen weed species in North America are confirmed glyphosate resistant.
Once alfalfa plants have 3-4 inches of new growth, stand health may be assessed by randomly selecting sites throughout the field. You want to see a minimum of 4-5 alfalfa plants per foot.
Early weed competition in soybeans can reduce yields where glyphosate is not applied early.
That’s the answer to how long it takes for corn to emerge; in other words, it depends.
