Main Weed, Pest, and Disease Pressure

Weeds compete with corn for water, light, and nutrients from emergence through canopy closure. Annual grasses like crabgrass, barnyardgrass, and goosegrass, plus broadleaf weeds such as purslane and amaranthus, are common in many corn-growing areas. If left unchecked, they reduce stand uniformity and make harvest harder.

Insect pressure varies by region and season. Stem borers, leaf rollers, aphids, and thrips can damage leaves, stalks, and ears. Fungal diseases such as rust, leaf blight, and sheath blight appear under warm, humid conditions. A practical program combines a soil-applied or early post herbicide, targeted insecticides, and a fungicide when disease risk is high.

Season Program Outline for Corn

Seed or seedling stage
Use a mycorrhizal soil conditioner or amino acid biostimulant to support early root growth. Apply a pre-emergence herbicide like pendimethalin 450 g/L CS before weeds emerge.
Early vegetative stage
Apply a post-emergence corn herbicide such as atrazine plus topramezone or atrazine plus fluroxypyr plus nicosulfuron when weeds are small and actively growing.
Late vegetative stage
Scout for stem borers, leaf rollers, and aphids. Use chlorantraniliprole plus monosultap or flonicamid based on the pest complex present in the field.
Flowering and grain fill
Watch for rust and leaf blight. Apply a propiconazole plus tricyclazole fungicide if disease symptoms appear and conditions favor spread.
Throughout the season
Amino acid fertilizers can be used as a supplemental foliar feed during stress periods. Confirm compatibility with your registered products before tank mixing.

Distributor Questions on Corn Products

Which corn herbicide should I stock for broadleaf and grass weeds?

A combination product with atrazine plus topramezone or atrazine plus fluroxypyr plus nicosulfuron covers many annual grasses and broadleaf weeds. Check the label of your registered product for local weed spectrum and use rate.

Do you offer a pre-emergence option for corn?

Yes. Pendimethalin 450 g/L CS is a selective soil-applied herbicide used in corn and other crops. It is most effective on annual grasses and some small-seeded broadleaf weeds before they emerge.

Can I get a corn fungicide and insecticide from the same supplier?

Yes. CHICO lists propiconazole plus tricyclazole for fungal diseases and chlorantraniliprole plus monosultap or flonicamid for insect pests. You can consolidate orders and documentation with one source.
