Corn and soybean planting season may have been extreme, but there are many benefits to seeding alfalfa this time of year. As alfalfa stands age, yield potential declines.
Downy mildew or crazy top is a condition that often results in wet or flooded fields. A crazy top results when plants are infected by Sclerophthora macrospora at flooding.
Goss’s wilt has rapidly become a significant and yield-reducing disease.
Take a look at your spray tips before you hit the field again. A few quick checks can help ensure all tips are operating unimpaired. Be sure all tips are spraying uniformly across the boom. Check to be certain all are calibrated correctly and uniformly.
Various species of stink bugs cause a range of crop damage. In soybeans, they typically do not produce damage enough to warrant treatment while soybeans are in the early reproductive stages.
Numerous cases of Frogeye leaf spot have been reported in fields of susceptible soybean varieties.
Trap counts often spike late in July as fall army worm moths take flight. Their larvae feed on crops causing defoliation and crop damage. With much of the crop going in late this year, AgVenture encourages growers to be on the lookout for the pest.
Black cutworms feed on newly emerged and young corn plants, causing damage, stress, and the clipping of seedlings. Carefully monitor fields for black cutworm activity.
Brown stink bugs feed on rolled leaves making several aligned holes appear in a row. If the growing point is pierced, plants tend to create tillers, diminishing its value to the crop as it competes for nutrients.
Controlling weeds is a contributing factor to maximizing yields. Post-emergence herbicide applications play an important role in managing weed populations before weeds and crops exceed specific stages. It is critical that growers always read and follow label instructions.
Meet your corn crop’s demand for nitrogen (N) when it needs it and with the right amounts and forms. Corn response to N fertilization improves when exposure to wet conditions is minimized.
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.
