nw NC | Different area of the country here and a long distance from you and perhaps different weed growth too. I always spray my burndown for no-till corn in late March/early April, weather permitting, using glyphosate and 2-4-D in plenty of water. Some early maturity corn is planted late April , then the rest of my full season silage corn is planted by late May and even to mid-June. There will be some new summer annual weed growth at the late planting dates, so the field will be sprayed again (sprayer on planter) with either glyphosate or paraquat depending on weed and grass species growing, and their size. All residual chemicals are applied at planting with sprayer on planter using water. Vegetation control with glyphosate is always diminished when using fertilizer solution as carrier due to fertilizer burn to plant before chemical can be taken in by the plant. Paraquat in fertilizer works good. Some nitrogen is applied in dry form broadcast shortly after planting, the rest in liquid form before corn is knee high. | |

Corn burn down?
