  • The response of tomatoes to atrazine as affected by magnesium and photoperiod

    Creator:
    Brenchley, Ronald Glenn
    Abstract:
    Studies were conducted to determine the nature of the interaction between atrazine (2-chloro-4-ethylamino-6-isopropylaminos- triazine) and magnesium on tomatoes. This interaction was studied under two light regimes: continuous light and a 12-hour photoperiod. Tomato plants were grown in sand cultures at three levels of magnesium fertilization. Four weeks after planting, atrazine...

  • The influence of magnesium on the toxicity of atrazine

    Creator:
    Brenchley, Ronald Glenn
    Abstract:
    Atrazine is an asymmetrical s-triazine herbicide used pre- and post emergence for weed control in many crops. Triazine herbicides have been used in the Pacific-Northwest for weed control in orchard crops. Under certain conditions where trees were grown in nutrient deficient areas, it was noted that toxic symptoms due to...
