Phenoxy herbicides include 2,4-D, MCPA, Crossbow, Banvel,
Garlon, Weed-B-Gone, and Brush Killer. They also are the active
ingredient (2,4-dichlorophenoxyacetic acid, 2-methyl 4-chlorophenoxyacetic acid, triclopyr, or dicamba) in “weed and feed” and brush control products for use in the home landscape.
Emissions largely associated with the combustion of fossil fuels and agriculture has caused elevated atmospheric deposition of nitrogen (N) and sulfur (S) throughout much of the developed world. Increased atmospheric deposition of N and S can lead to soil and surface water acidification and affect forest soil nutrient supply. The...
Spectral patterns of three brush species under the influence of herbicide treatment were investigated to evaluate the effectiveness of monitoring forest vegetation management using ground-based and remote sensing techniques. Foliage of Pacific rhododendron (Rhododendron macrophyllum D. Don), golden chinkapin (Castanopsis chrysophylla Dougl.), and hairy manzanita (Arctostaphylos columbiana Piper) sprayed with...

Alnus rubra (Bong. ) seedlings were grown in sand culture and
irrigated with nutrient solution containing CdCl₂
ranging from 5 μg to 100 mg per liter. Treatment of A. rubra seedlings for 4 weeks
with 50 and 100 mg CdCl₂
per liter of nitrogen-free nutrient solution
decreased in situ nitrogenase...
The effect of nitrogen (N) application on seed yield of Limnanthes
alba was studied for two years at two locations. Seeding following alfalfa
(Medicago sativa L.) was compared to establishment after wheat
(Triticum aestivum L.). Treatments used were a control (no N applied),
and two rates of N (50 and...
