What causes volunteer corn?
If you don’t set your combine adjustment properly (and sometimes even if you do) you throw good corn seed out the back. This is the primary source of “volunteer” corn. These seeds will sit on the soil surface, or get mixed into the soil with tillage, and grow the next year.
What is the most effective timing of an appropriate herbicide used to control broadleaf perennial weeds in corn?
Pre-tillage glyphosate applications should be made at least seven days prior to tillage or mowing. The addition of 2,4-D may improve effectiveness on some perennial species. The rate of 2,4-D is dependent on the crop (due to crop safety) and the timing of application relative to planting date.
What is fungicide efficacy?
Efficacy is based on proper application timing to achieve optimum effectiveness of the fungicide as deter- mined by labeled instructions and overall level of disease in the field at the time of application.
How does Smartstax Pro work?
In the case of SMARTSTAX PRO, scientists harnessed RNAi to create a pesticide that works by silencing or turning-off the activity of a gene critical to corn rootworm survival. Corn rootworm damages corn plants growing in the field by eating the roots.
Will volunteer corn produce ears?
Volunteer Corn Scouting: The green leaves have a midrib that is lighter in colour; they are linear and can grow between 11 and 40 inches in length. They produce tassels or inflorescence at the top and ears of corn growing off the stems.
What herbicide kills volunteer corn?
Assure II (quizalofop-p-ethyl) is the only grass herbicide labeled to control volunteer corn in Enlist Corn. It can be applied at 5 to 12 fl oz/acre in Enlist Corn for selective control of Roundup Ready + LibertyLink volunteer corn.
What herbicide kills grass in corn?
In conventional corn it’s much different. Our best recommendation here is to use a full rate of one of the straight grass residual herbicides: Harness, Surpass, Outlook, or Dual. Apply them with either light, shallow incorporation OR leave them on the soil surface and let rain work them in.
What should I spray before planting corn?
Use Non-Selective Weed Killer Before Planting
- 3–4 weeks before planting corn, spray the entire corn patch with your weed killer of choice.
- Wait 1 week for weeds to die.
- Rake away dead weeds.
- For 1–2 weeks, water your corn patch as you would during the growing season.
What is crop protection management?
Crop protection is the science and practice of managing plant diseases, weeds, and other pests (both vertebrate and invertebrate) that damage crops and forestry. Crops include field crops (maize, wheat, rice, etc.), vegetable crops (potatoes, cabbages, etc.), and fruits.
What can you spray on SmartStax corn?
SmartStax® RIB Complete® corn blend has the broadest spectrum of insect control on the market — with Roundup Ready® 2 Technology and LibertyLink® Herbicide Tolerance for broad spectrum weed control. See how SmartStax® Technology stacks up against other above- and below-ground traits.
What is SmartStax pro?
Protects Against Above- and Below-Ground Pests In addition to corn rootworm, SmartStax® PRO Technology will also provide protection against above-ground pests including European corn borer, southwestern corn borer, fall armyworm, black cutworm and corn earworm. Compare Now.
How do I get rid of volunteer corn?
The best solution to control non-GMO corn will be to use tillage or glyphosate. Non-GMO corn is very sensitive to glyphosate and no waiting intervals are needed to replant. You can also use glyphosate or tillage to control Liberty Link corn hybrids (as long as the hybrid is not also Roundup Ready).
How do you deal with volunteer corn?
Here are a few options to take control of Volunteer Corn in new corn fields. Ignite herbicide will reduce the competiveness of Volunteer Corn by killing the emerged leaves. If Volunteer Corn has traits resistant to the active ingredient glyphosate, applying either SelectMax or paraquat can be used.
When should you spray corn?
Drop nozzles should be used for optimum spray coverage and weed control when corn is 24 to 30 inches tall. When corn is 30 to 48 inches tall, only use drop nozzles and avoid spraying into the whorls of the corn plants. Some labels also indicate the minimum corn growth stage before POST applications should be made.
What is the best herbicide for corn?
Glyphosate (Roundup) and glufosinate (Liberty) are two effective options to manage volunteer corn, but many corn hybrids contain resistance traits for one or both of these herbicides. As with other weeds, controlling emerged volunteer corn at planting to ensure a weed-free start is critical.
Can you spray corn with Roundup?
In corn with Roundup Ready® 2 Technology, Roundup® brand glyphosate-only agricultural herbicides can be applied broadcast up to the V8 growth stage or 30-inch tall corn, whichever comes first. Drop nozzles should be used for optimum spray coverage and weed control when corn is 24 to 30 inches tall.
What stage do you spray corn?
For example, Capreno® herbicide can be applied POST when corn reaches the V1 stage up through V7 or 20-inch tall corn, whichever comes first. Broadcast applications of Capreno herbicide in corn grown for seed are recommended from the V1 to V5 growth stages.
What are the 3 phases of crop protection?
How we do it: Breeding for resistance and Integrated Pest Management (IPM)
- Biological control. Biological control is the use of natural enemies — predators, parasites, pathogens, and competitors — to control pests and their damage.
- Cultural controls.
- Mechanical and physical controls.
Can I spray Liberty on SmartStax corn?
Liberty is the ONLY working nonselective herbicide that is effective on tough-to-control grasses and broadleaf weeds. * Plus, it’s available for over-the-top use on over 50 million LibertyLink®-enabled corn hybrid acres with Herculex®, Genuity® SmartStax® and Agrisure® hybrids with corn borer protection.
