  1. Herbicide Resistance in Waterhemp

    Jan 21, 2020

    Problem: Waterhemp is becoming resistant to everything Waterhemp is a dioecious species, with separate male and female plants. Cross pollination results in tremendous variability within populations, which is evident from differences in plant color and other characteristics. This genetic variability results in a relatively high frequency of mechanisms that can impart resistance to herbicides, enabling waterhemp to develop resistance more rapidly than most weeds. Waterhemp can produce over 1,000,000 seeds per plant.

  3. Proper Calibration and Operation of Backpack and Hand Can Sprayers

    Manually operated sprayers (hand pumps, hand cans, and backpacks) are designed for spot treatment and for spraying smaller areas such as tree seedlings, small lawns, or flower beds not suitable for power sprayers. As is true for all sprayers used for application of chemicals, application accuracy with backpack and hand can sprayers is affected by travel speed, nozzle type, and spray pressure. Uniform distribution of sprays can be difficult even with training and regular calibration.
