NEW NDSU WEED SCIENCE HOME PAGE
The NDSU Weed Science home page listed on the front and back cover of the weed guide is no longer available. The new address is www.ndsu.edu/weeds. The new web site reflects a homogenous look with other NDSU web sites.
All features that were in the old web site are available in the new web site with a couple of changes. The electronic version of the weed guide is available now in .pdf format which is different than the html code style previously listed. The electronic version of the 2009 ND Weed Guide is also available at the new web site. The biggest change between the hard copy of the 2009 ND Weed Control Guide and the electronic version is the Herbicide Compendium. Herbicide prices has been updated to the 2009 season.
Herbicide prices are averages of four different suppliers. Many herbicide prices remain the same or had a slight increase. Some herbicides prices that are higher in price are: acetochlor, atrazine, Beyond, MCPA, Extreme, Pursuit, Raptor, and 2,4-D. The price of ammonium sulfate (AMS) is much higher now but is expected to come down. The price of most adjuvants are higher also.
Many SU herbicides are now available through generic trade names. Most of the generic SU herbicides are much lower in price than the original products. The price of some generic clethodim and clopyralid formulations are lower than in 2008.
Most generic 3 lb ae/gallon glyphosate formulations are in the $25 to $30/gallon range while the Monsanto brands are slightly higher than 2008.
ALERT - TELEMARKETERS
It is again the season of telemarketers selling products that are excessive in cost and usually do not do what is claimed. Below is an article that I wrote several years ago about a product called Triple Threat which I hear from Jim Gray at the NDDOA is being sold through the telephone again in the state. The dollar comparison listed below is based on early 1990 herbicide prices so the actual amount now would be much more. There are many other products being sold through telephone sales - As a "Rule of Thumb" - If it sounds too good to be true - it is too good to be true - HANG UP!
Telemarketers are out in full force selling high priced herbicides that contain very little active ingredient, and claiming these herbicides can do unbelievable things. We need your help to shut these people down. The ND Dept of Ag has indicated that with proper documentation of phone call conversation they can take action against companies that use this approach to rip-off growers of their hard earned money.
For example, reports have been made of a chemical company selling a product containing 2,4-D and bromacil (Hyvar) at a total concentration of 2% ai for $90/gal + $21 freight. By my calculations, the grower is spending the equivalent of: $3,961.76 for a gallon of 2,4-D LV4 and $2,610.33 for a gallon of Hyvar XL.
In North Dakota, an average price for 2,4-D LV4 is $14 per gallon and $55 per gallon for Hyvar XL (2 lb/gal). They are selling this herbicide for 47 times and 283 times the cost than if the grower were to buy the 2,4-D LV4 and Hyvar XL from his dealer.
Absurd claims are made with these products. For instance, one application of a product called Triple Threat (three phenoxy herbicides at a total of 1 lb/gal) was report by the telemarketer to control leafy spurge for 5 years. Do you think the telemarketer would sign his name to the guaranty - NOT!
Get the following information during the phone call - if you can:
We need your help to rid our state of this pillage. Please document the call and report to the ND Dept of Ag at 701 328-1505. When calling the Dept of Ag ask if the product is registered in the state. If it is not registered, it is a good indication its ‘scam brew’.
SPARTAN SECTION 18 FOR FLAX APPROVED
The U.S. EPA has approved his request for a Section 18 specific exemption for Spartan 4F®, enabling North Dakota flax producers to apply the herbicide to control kochia and ALS-resistant kochia. The exemption allows a single ground application of 3 to 8 fluid ounces per acre of Spartan 4F, depending on soil type. The application must be made up to 30 days before and three days after planting. Applicators must follow all directions, restrictions and precautions on both the Section 18 use directions and the EPA- registered product label. They must have a copy of the Section 18 use directions in their possession during application. The exemption allows for treatment of 250,000 acres of flax. FMC Corp., the manufacturer of Spartan 4F, supported the exemption request.
Questions have been asked whether the Section 18 exemption is specific for Spartan 4F or if users can use other sulfentrazone formulations such as Spartan Advance or Spartan Charge. The exemption is specific for Spartan 4F, meaning that users cannot use other sulfentrazone products on flax. Users can, however, tank mix Spartan 4F with other pesticides that are labeled for use on flax. Copies of the exemption use directions can be found at:
