Dr. Kanissery’s research and extension programs are focused on the weed control and herbicide use associated with citrus and vegetable production in Southwest Florida. The primary goal is to develop effective, economical and crop-safe weed management practices in citrus and vegetable production.   Examples of his program areas include herbicide efficacy testing, herbicide residue analysis, and crop injury prevention. He also provides a statewide service for weed identification and diagnosis of herbicide phytotoxicity in conjunction with the Plant Disease Diagnostic Clinic at SWFREC.


  • Evaluate long-term weed control prospects of pre-emergent herbicide combinations by utilizing synergy between diverse modes of actions.
  • Understand the impact of herbicide persistence and exposure on crop health and productivity in citrus and vegetables.
  • Improve herbicidal efficacy and safety by utilizing surfactants, additives, slow-release carriers, etc.
  • Evaluate alternative and novel weed control tools for attaining goals of effective and sustainable weed management in horticulture production systems.


  • Optimize efficient and economical weed management practices in citrus and vegetables.
  • Provide weed identification, management, and herbicide phytotoxicity diagnostic/mitigation education and services.
