Herbicidal effectiveness of trifluralin as influenced by methods of incorporation into the soil and depth of weed seed germination

Creator:: Gargano, Don Richard
Abstract:: This study was conducted to compare the effectiveness of four methods of incorporating the herbicide trifluralin into the soil, and to determine the interaction between depth of incorporation of trifluralin and depth of weed seed germination. Field experiments on green and dry peas were established in Oregon and Idaho. Trifluralin,...

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...
