Research Project: Testing of Mbi-005 for Cut Flower Production

Location: Subtropical Plant Pathology Research

2013 Annual Report


1a.Objectives (from AD-416):
To determine if the biologically-based, broad-spectrum bioherbicide product MBI-005 can be utilized as a weed control material for high value cut flower production in Florida and Tennessee.


1b.Approach (from AD-416):
Greenhouse and small-scale field trials will be conducted to evaluate MBI-005 as a preplant and postemergent bioherbicide.


3.Progress Report:

This research directly relates to inhouse objective 1. Develop new management strategies for control of pests and pathogens currently or previously controlled by soil fumigants in vegetable and ornamental cropping systems and 2. Integrate cultural, biological, and chemical control tactics into technically feasible pest management programs for soilborne pests and pathogens.

Pre and post-emergent activity of MBI 005 bioherbicide was evaluated in replicated, repeated greenhouse experiments during late fall 2012 to spring 2013. This study was conducted to test activity of MBI 005 bioherbicide on yellow nutsedge (Cyperus esculentus) and endemic weed populations from an organic cut flower/vegetable production field. This study also evaluated phytotoxicity of MBI 005 on snapdragon (Antirrhinum majus), romaine lettuce (Lactuca sativa), and tomato (Lycopersicon esculentum). Treatments included: control (no bioherbicide), pre-emergent application (pre-plant incorporated), post-emergent application (simulated drip), and a combination of pre and post-emergent applications. Analysis of data from these studies is ongoing and will be used to design future studies, including a field study of MBI 005 use in cut flower production. Initial results suggest that MBI 005 improved control of a number of weed species compared to an untreated control.
