Efficacy of a Fugal Pathogen and Biological Control weevil on Limiting Eurasian Water Milfoil Biomass

Proposal #4 (Grokenberger) was focused on invasive Eurasian water milfoil. The author was interested in researching the effects of a fungal pathogen, M. terrestris, on Eurasian milfoil biomass in realistic conditions outside a laboratory. Since, weevils had previously been used in biocontrol, they decided to compare the ability of the fungal pathogen to manage Eurasian water milfoil by itself and with in conjunction with weevils.

Integrating chemical, biological, and mycoherbicidal control of Alligator weed to reduce weed growth in North Carolina

Majumdar’s pre-proposal is focused on the alligator weed, an invasive species which forms giant mats over aquatic bodies and blocking our sunlight.  The paper suggests preforming a study on the plant by testing several different types of control methods, namely a flea beetle, mycoherbicide, and herbicide, and then various combinations of the three.  The goal is to see which single treatment or combination of treatments is most effective at reducing the growth of alligator weed over the course of six months.

The efficacy of biocontrol on invasive Melaleuca quinquenervia in the Everglades

The Melaleuca tree is an invasive plant in the Florida Everglades and especially thrives under moist conditions. The tree covers nearly 0.6 million hectares of land and is an ecological and economic concern in the Everglades, costing the US $2 billion while reducing biodiversity. The author plans to explore biological control in combination with chemical control on the tree and whether water levels influence each control method. The methodology calls for 40 saplings, each subjected to different irrigation levels to simulate water levels and various combinations of biological and chemical control. After two years of weekly observations, the trees’ biomasses will be measured to determine if the control methods were successful in stopping the growth of the Melaleuca tree.

Hyperspectral Remote Sensing of Hydrilla verticillata

The goal of this study is to use remote sensing to create a spectral library of the annual lifecycle of hydrilla, an invasive plant. The proposal suggests that remote sensing will improve upon the costly and inefficient field based methods that have been used in the past, and help to better detect the distribution of hydrilla in various environmental conditions.


Our group chose to recommend Mejia’s “Efficacy of biocontrol on invasive Melaleuca quinquenervia in the Everglades”. This pre-proposal outlined a study that sought to determine the effects of both biological and chemical control methods on the Melaleuca tree, an invasive plant in the Florida Everglades. The pre-proposals objectives were two-fold; first, determine if water levels influenced the efficacy of biological controls on the tree, and second, to determine if an herbicide would be effective in combating the tree along with the biological controls.

While the pre-proposal was obviously well thought out and very informative, our group thought that it was perhaps a bit too descriptive for a pre-proposal. We were questioning whether sections needed to be elaborated on, such as the Objectives and Hypothesis portion. There was information presented that may not be necessary for a pre-proposal, but would be more appropriate to add in a full proposal. In short, the paper as a whole could certainly be condensed to make less complicated or extensive. In addition, towards the end of the pre-proposal, the author tended to be repetitive, which adds to the density of the paper. We would advise the author to figure out and separate what is pertinent to the pre-proposal and what is simply superfluous.
