Insects – Dropping down from SmartStax® to VT Double PRO® means giving up belowground insect protection on pests like corn rootworm. Be sure to use a planting time insecticide like Force, Aztec, or Capture LFR, as there is no rescue treatment for corn rootworm.
Weed Control – If you are used to using Liberty® or Roundup® in SmartStax® corn, remember VT Double PRO® is only tolerant to Roundup, not Liberty.
Use a PRE – Don’t skip the powerful weed control options you have for residual control. Apply them at or hopefully before planting.
Product Choice – If broadleaf weeds are a huge issue, choose a pre-emerge product to address those weeds and take many of them out before they even emerge from the soil. Products like Verdict and Resicore are great options, but there are many more, as well.
Multiple Effective Modes of Action – Be sure to use multiple effective modes of action each time you spray for weeds. For example, Status is a great post-emerge choice because of it’s broad-spectrum weed control and two highly effective modes of action on most weeds. Avoid spraying straight Roundup® or any single mode of action as resistant weeds are out there and growing in severity each year.
Diseases – Watch the Hefty Brand Corn hybrid characteristics chart and consult the management tips for each hybrid. Most hybrids have one disease or another that may require extra protection from a fungicide. Many of the diseases will show up in fields after V8 and come during very sensitive growth stages. Avoid the use of surfactants or oils with your pre-tassel fungicide applications to protect your crop from arrested ear development.
