Drift issues have grabbed a lot of attention this year. herbicide drift, in particular, can have a dramatic effect on your crops, and it naturally gets most of the attention when drift issues are discussed. Yet even insecticide, fungicide, or other spray material drift can create problems. Frankly, I consider any drift to ...

Lead author of the study Rob Freckleton, Professor of population biology from the University of Sheffield, said: "The driver for this spread is evolved herbicide resistance: we found that weeds in fields with higher densities are more resistant to herbicides. "Once resistance has evolved it does not seem to go ...

Robert Freckleton and colleagues looked at the UK occurrence and herbicide-resistance of black-grass--a high-density weed which commonly competes with cereal crops. The authors also surveyed farmers about their use of herbicides--and how much their respective approaches cost. The team found ...
The group believes herbicide chemicals can contaminate the Cape's sole aquifer. "We said 'please can we have a separate Vegetation Management Plan' and they said they would. Well, we'll see what it says, hopefully without herbicides. I hope they take into consideration our aquifer is right below us, not ...

The battle over the use of herbicides under power lines on Cape Cod and Martha's Vineyard is once again underway. The Department of Agricultural Resources has scheduled two hearings in March on the 100-page, five-year vegetation management plan for the region, recently submitted to the state by ...
The use of herbicides, which are ecotoxins, should be used as little as possible, as they do get into groundwater/aquifers. Most of today's herbicides have been designed to degrade faster than the previously used chlorinated hydrocarbons but they are still foreign to all life forms -- you and me included.
The researchers tested nine chemicals that bees normally encounter in plants and hives along with two herbicides--atrazine and glyphosate--and three fungicides--boscalid, chlorothalonil, and prochloraz. The results were unexpected. The bees preferred sugar syrup laced with glyphosate--the herbicide ...
"We have conducted nearly 60 experiments on specialty crops in an effort to understand their sensitivity to drift from various agronomic herbicides," he says. "Example: You just don't spray a herbicide like dicamba near a tomato crop (or many other crops), which can be worth $30,000 an acre. You also don't ...
Many farmers have begun to use multiple actions to combat herbicide resistance and are on the cusp of good weed management in Iowa, long-time weed scientist Mike Owen says. But, herbicide resistance continues to grow, and at an increasing rate. Multiple resistance is becoming the norm, with no new ...
BEND, Ore. - The U.S. Forest Service is seeking comments on a proposal to add the herbicide aminopyralid to the list of available herbicides on the Deschutes and Ochoco national forests and the Crooked River National Grassland. Forest Service officials say aminopyralid is more effective than the ...

farmers have relied upon glyphosate-based herbicides to kill unwanted vegetation for more than four decades, but its use sparked hefty debate in 2015, when the World Health Organization's International Agency for Research on cancer (IARC) concluded that it was "probably carcinogenic," adding it to a ...
However, POST applications are only one part of a soybean herbicide program. To achieve successful weed control, all the herbicides you apply, either in the burndown, pre-emergence (PRE) or POST applications must work together, using multiple modes of action (MOA) and sites of action (SOA).
A Hersey area farmer broadcasted a mix of Oilseed Radish, Crimson Clover, and Rye into his corn field after applying a contact herbicide with no .... Issues were found with other types of cover crops, so herbicides from this group may not be a good choice for those producers looking to seed a cover crop ...
Mike estimates the total loss at $300,000. Tests revealed that the herbicides responsible for the damage were glufosinate, clethodim and metolachlor. Their Certified Naturally Grown certification was suspended, and the Brabos must essentially start over to remove the herbicide contamination from their farm. It will take three ...
LITTLE ROCK, Ark. (AP) - A special panel of judges says 11 lawsuits filed in four states against the makers of the herbicide dicamba will be centralized in federal court in St. Louis. The U.S. Judicial Panel on Multidistrict Litigation made the determination Thursday regarding farmers' lawsuits filed in ...
The fifth year, about 60 percent of the weeds are now resistant, Lyon said. The length of time varies, depending on cultural practices, frequency of herbicide use and the biology of the weed species. Group 2 herbicides, or ALS inhibitors, tend to be overcome relatively quickly, Lyon said. That's the class used ...
Adjuvants: no restrictions when applied preemergence. Do not use MSO when applying postemergence. Do not apply with COC or nitrogen-based adjuvants when applying postemergence to yellow popcorn. Do not use COC, MSO, or nitrogen-based adjuvants when tankmixing with Liberty herbicide.

Although the cover crops cost me $24 per acre, I saved that much in herbicide applications, although we did apply herbicide before the next cash crop, ... soil health practices has improved my soil organic matter content and I've reduced the amount of commercial fertilizer and herbicides on cash crops.
Another meeting I'd encourage our area farmers to attend is the herbicide Resistance Workshop, to be held on Feb. 23 from 8 a.m. to noon here in the Frederick County Extension office. Anyone who grows grain, especially soybeans, knows that weed pressure isn't getting any better. We now have at least ...
Des Moines, Iowa (KCRG-TV9) -- The herbicide dicamba has been used for decades in corn and pastures, but in 2017, it was approved for soybeans. In the last year, application problems with the product has caused thousands of complaints across the U.S. Because of that, registrants of dicamba like ...
I'd like to offer Jennifer Solomon (guest viewpoint, Jan. 2) a glass of water from the watersheds that have been sprayed with herbicides. She states that the public testimony at the county commissioner meeting on Dec. 19 against aerial spraying of known carcinogens was just "shenanigans." How nice that ...
The borough has opposed larger proposals for herbicide spraying in the past, whether it was proposed for vegetation control along state highways or forest treatment on Native corporation land. Local elected officials have even discussed a ban on herbicides and pesticides but never passed such a law.
WALL - The Texas A&M AgriLife Extension Service will conduct a series of auxin trainings for producers in Runnels, Tom Green and surrounding counties, according to organizers. "The Texas Department of agriculture has required a special auxin-specific training in 2018 for those applying the new auxin ...
Agricultural legislators in Arkansas are moving ahead with a motion to place a seasonal ban on a common soybean herbicide. The state Plant Board voted 11-3 yesterday in favor of the dicamba ban, which would be in place from April 16 to Oct. 31. In December, legislators had considered delaying the ban ...
French President Emmanuel Macron has declared he will ban the American herbicide glyphosate within three years, and sooner if a replacement is ready. Italy has vowed to do the same. activists have said the replacement is already available, and it has been used in France since 1863 - a fatty acid called ...
MU Extension will conduct both in-person and online training for synthetic auxin herbicides applicator training. In-person training sessions will be held at five locations in January and February. To register or for more information, visit extension.Missouri.edu/main/spotlight/dicamba.aspx. For questions, call ...
glyphosate is the world's most widely used herbicide, and underlies much of Monsanto's franchise in crop seeds. Monsanto sells corn, soybean and cotton seeds genetically engineered to withstand glyphosate, which have come to dominate U.S. farm fields. The St. Louis company also sells the spray itself.
Dicamba has been around for decades, but problems arose over the past couple of years as farmers began to use it on soybean and cotton fields where they planted new seeds engineered to be resistant to the herbicide. Because it can easily evaporate after being applied, the chemical sometimes settles ...
"Texas A&M AgriLife is holding trainings in many locations, so it makes sense to have one in Tulia," Villalba said. "We want as many producers as possible to attend this training to prepare for the 2018 crop while being sure we are doing our part to legally apply these herbicides. These technologies are big ...
A new paper published in the journal GM Crops and Food points to significant increases in carbon emissions and a worse environmental impact associated with weed control practices if farmers around the world stopped planting glyphosate-tolerant crops. Decreased production of important agricultural ...
The federal Environmental Protection Agency on Monday said glyphosate, the primary ingredient in the weed killer Roundup and one of the most widely used herbicides in agriculture, likely does not cause cancer. The assessment contradicts the conclusion of a European scientific panel as well as ...
BLYTHEVILLE, Ark. (AP) -- In a story Dec. 14 about a second-degree murder trial involving farmers in Arkansas, The Associated Press erroneously reported that the herbicide dicamba was made by Monsanto. Monsanto is one of several companies that make dicamba, but it does not sell its product in ...
The EPA's risk assessments, which sometimes rely on industry-funded studies, look at the long-term threat pesticides and herbicides pose based on the anticipated uses and the relatively low levels of exposure expected for humans and animals. IARC's finding that glyphosate is likely carcinogenic triggered ...
The platform leads to a 90% reduction in herbicide use. Additionally, there are. In addition to the application reduction, it also minimizes off-target drift. The volume/acre is reduced, and larger droplet sizes can be used. See & Spray can help prevent herbicide resistance with rotating herbicides modes of ...
Both products are designed to be cost competitive and provide high quality formulations. Helmet herbicide contains 7.8 pounds of metolachlor plus benoxacor safener per gallon. Helmet SPC herbicide contains 8 pounds of metolachlor without safer per gallon. Both products are packaged in 2 x 2.5-gallon ...
So far, glyphosate has been hard to replace: Other herbicides just aren't as effective or as easy on the soil, and the best of the alternatives are more expensive to boot. The current fudge -- a cautious five-year extension with an easy loophole for unwilling member states -- is a typical European compromise ...
Following concerns from applicators regarding a portion of the federal label, a recommendation for Loyant, a rice herbicide, was not offered pending potential further action by the EPA. "Enlist One contains the same 2,4-D choline salt that's in Dow's Enlist Duo. It just doesn't have the glyphosate component ...
There is no silver bullet for herbicide resistant weeds. If growers come to over-rely on dicamba products, history suggests that the cycle of resistance will continue, and we will face increased weed resistance to dicamba as we have with glyphosate, triazine, and ALS-inhibitor herbicides. It is important to ...
Gramoxone (paraquat) - This post emergence herbicide can be applied between cuttings. "The action is very quick," Creech says. "Often visible in a matter of hours." The chemical becomes inactive once it comes in contact with soil so there's no residual benefit. According to Dwight Lingenfelter with Penn ...
Each year, weed scientists from across the Midwest meet for the North Central Weed science Society (NCWSS) meeting. Here are three points they have discussed so far this week at the NCWSS meeting St. Louis, Missouri. • farmers want new herbicides and new herbicide site of actions. That's the ...
