Problems resulting from last year’s drought are far from over, and farmers will need to take necessary precautionary steps to stay on top of weed and insect management. If you haven’t already started planning your management program for this year, now is the time to start.
One of the hardest challenges you will encounter with weeds is your application timing. Depending on the weather this spring, it may be too windy or rainy to be out in the fields when you want to be. Last year’s drought has caused a variety of concerns related to what we can expect this year.
Palmer Amaranth, a glyphosate resistant broadleaf weed, is expected to be a concern for this season due to its high water efficiency and its competitiveness among other pigweed species, according to Vince Davis, a weed scientist from the University of Wisconsin in the article Weed management concerns germinate post-drought.
According to Dr. Kevin Bradley from the University of Missouri, 18 states are currently dealing with glyphosate resistance in Palmer Amaranth.
Davis suggests using an early preplant application as part of your weed management plan to overcome weed problems in your fields.
Recalling last spring, Davis points out that weeds were able to get a jump start on growth with the early spring weather. This was paired with dry, dusty conditions that made spray conditions difficult in many areas. Together, this has created a great situation for weeds to take over.
Insect problems in the field vary from year to year, and it is necessary to monitor all of your fields for insect pests that can damage your crops.
According to the 2013 Insect Control Recommendations for Field Crops, provided by the University of Tennessee, certain production practices can greatly hurt your crops and should be avoided while others can help your crops. Destruction of weeds and cover crops by tillage or herbicide three or more weeks before planting will reduce the risk for cutworm infestations.
Some of the more common insecticide resistance problems are related to managing the tobacco budworm in cotton, cutworms which are mostly found in reduced tillage or legume cover crops and bean leaf beetles on soybeans.
As with any pest management plan, early detection is important to keeping the problem from spreading. While some of the insects you find can be detrimental to your crops, others such as lady beetles, brown lacewings, and assassin bugs can be beneficial as well. It is important to implement regular scouting in the fields and to be able to properly identify insects. This will help you develop your pest management plan.
