Triple threat herbicide resistant goosegrass

Researchers from the Australian Herbicide Resistance Initiative report on the first confirmed case of a weed, Indian goosegrass (Eleusine indica), resistant to three non-selective herbicides, glufosinate, glyphosate, and paraquat along with several ACCase inhibitor herbicides (Jalaludin et al., 2014). The goosegrass population was initially reported in Malaysia by a vegetable farmer and a planter from an oil palm nursery (Jalaludin et al. 2010).

In the United States, E. indica occurs in forty five of the fifty states. In Wisconsin, populations have been identified in the following counties: Columbia, Dane, Grant, Lafayette, Rock, Kenosha, and Milwaukee. The first documented case of herbicide resistant E. indica was from North Carolina in 1973 and the latest confirmation was in 2011 (Heap, 2015).

The amount of glufosinate to kill half of the tested resistant plants was equivalent to applying 40 fl oz per acre (e.g. Liberty 280 SL). The maximum rate for the season in corn is 36 fl oz per acre. The next generation of plants from the resistant population required 657 fl oz per acre of glyphosate (i.e. Roundup Powermax) to kill half of the tested population. These plants also were twice as resistant to paraquat compared to the susceptible plants. Half of the resistant population survived applications of the ACCase inhibitors- haloxyfop-P-methyl (e.g. Verdict) and fluazifop-P-butyl (e.g. Fusilade).

UW-EXTENSION FARM TRANSITION AND SUCCESSION

PLANNING SURVEY

Farm succession has, by many local and statewide experts, been identified as one the most

urgent issue affecting farmers in Wisconsin. Nearly 6,000 Wisconsin dairy farm operators

(or two of every three) do not have a successor identified, leaving families, communities and

local economies in a state of financial insecurity.

This UW-Extension Farm Transition and Succession Planning Survey has been created

to determine needs regarding farm transition and succession planning for among farm

businesses in the state. Those with knowledge of the day-to-day operations and those who

own farmland are encouraged to participate in the survey. Any type of farm business can

participate in the survey if they are defined as a farm according to IRS definitions ($1,000

gross sales). Not all questions may apply to the situations of individual farms and no

question is required to be completed.

This UW-Extension Farm Transition and Succession Planning Survey was developed in

collaboration with Kenosha, Walworth and Racine Counties Cooperative Extension offices

with financial support from the UW-Extension Farm Team and Center for Dairy Profitability.

This workshop series is for farm women who are interested in learning or improving their farm financial management, which is part of the fabric of farm life. The series will be inter-active between speakers and participants with in-class exercises.

Topics include:

  • Introduction to Financial Management
  • Records and Recordkeeping Systems
  • Filing Important Family Papers
  • Management Reports including the Balance Sheet and Income Statement
  • Analysis and Interpretation of Financial Statements

Annie’s project is an opportunity for farm women to learn about farm management skills by providing resources and information to improve farming operations. Class sizes are small which allows for opportunities to network with other farm women in similar situations.
