Witryna22 lut 2024 · Under dry conditions, more herbicide clings to soil colloids, making it unavailable for weed seedlings to absorb. That’s why it often requires 0.5 inches of rainfall or more to move herbicides from the soil surface into the weed seedling zone and keep the herbicide in solution for a few days so it can be absorbed by the weed … Witrynatiming impact carryover. Misapplication, either by applying more than the labelled rate or overlapping spray patterns, increases the potential for herbicide carryover. Likewise, the later an herbicide with residual activity is applied in a growing season, the higher …
