Research
Dr. Singh is responsible for total weed management research program for citrus. The main objective of my program is to develop the most efficient, economic, sustainable and environmentally sound weed management system for Florida citrus. In order to achieve these objectives, currently I am working in the following areas of weed science:
Using both, field and laboratory approaches, research is being conducted on:
- (1) determining the efficacy of available herbicides including chemical screening and phytotoxicity,
- (2) increasing the effectiveness of herbicides, including volume, time of application, additives, and equipments,
- (3) weed biology, including seed germination ecology,
- (4) integration of weed control methods for citrus nurseries and groves with production practices,
- (5) allelopathy and other biological control methods,
- (6) herbicide physiology, herbicide resistance, and
- (7) herbicide-soil interaction studies on leaching behavior of herbicides to reduce the risk of groundwater contamination.
