Response of Tropical and Subtropical Woody Plants to Chemical Treatments

摘要

Research was conducted to evaluate new herbicides or combinations of herbicides for killing tropical and subtropical vegetation, develop methods of evaluating herbicides on different woody species, determine the effects of environment on behavior and effectiveness of toxic herbicides, determine optimum dates and rates of application, relate the percentage of defoliation to horizontal and vertical obscuration, develop methods for improved application techniques that provide better distribution patterns, and obtain the botanical information needed so that correlations might be made between vegetation indigenous to Continental United States (CONUS), Puerto Rico, and Southeast Asia.
