Soil conditions are excellent for cultivation at the moment, and there is a lot of field work going on, mainly grass reseeding , but also the drilling of cereals. With a longer gap than usual between harvesting and drilling autumn crops, some stale seedbed cultivations have been carried out, to assist control of brome and other problematic grass weeds.
Be aware though, early drilling of crops brings its own problems. When temperatures remain mild, aphids numbers remain high and will quickly move into new crops as these emerge, therefore increasing the likelihood of BYDV infection in all emerged winter crops. Early drilling also increases the likelihood of disease infection. Lush crops of winter barley going into the winter are much more susceptible to Rhyncho and Mildew, as was prevalent last winter. Early drilling of winter wheat in particular significantly increases the likelihood of Take-all and an appropriate Take-all seed treatment should be applied as a matter of course. Winter oats are particularly susceptible to Mildew.
Annual meadow grass and broad leaved weeds
Annual meadow-grass (AMG) continues to be the most problematic weed in autumn cereals. If not properly controlled, this weed grass will continue to grow throughout most of the winter and once well tillered is impossible to control effectively. Flufenacet, available in various mixes, is the principle active in autumn herbicide programmes to control AMG, giving pre and post emergent activity of the weed grass. It has limited broad-leaved weed activity but is very effective on a wide range of other grass weeds, including all species of brome. Whilst HAMLET and OTHELLO are effective alternatives to flufenacet for controlling AMG in winter wheat, in the early spring, there are no such options for barley, rye or oats. The key to effective control in winter barley and rye is to apply flufenacet (not oats) before or soon after emergence of the crop, critically before the AMG has begun to tiller. Only when soil temperatures have dropped, pre-emergence of the crop is very effective and with GPS technology this is an option.
Other actives used at this time include pendimethalin (PDM) and diflufenican (DFF). PDM is also active on AMG but pre-emergent only. It is relatively insoluble and so persists for an extended period in the soil. PDM also has a wide broad leaved weed (BLW) pre-em spectrum, including chickweed and fumitory, but not groundsel. DFF is a residual with both pre and post emergent activity. It has no AMG activity but has a wide spectrum of BLWs including large chickweed and field pansy, but no activity on fumitory or groundsel.
FMC (formerly Headland) have introduced a new broad spectrum autumn herbicide called NUCLEUS, containing flufenacet and DFF. Whilst the grams of both actives are the same as LIBERATOR and therefore performs in an identical way in the field, NUCLEUS has a broader label with full approval for use on winter rye and triticale, alongside winter wheat and barley.
The persistency of any herbicide product that has residual activity is directly linked to soil temperature – the lower the temperature the longer the duration of its persistency. As soils cool in the coming weeks and months, product performance will improve the longer application is delayed into the winter.
Soil acting herbicides also require adequate soil moisture to work, but a persistently wet winter will also adversely affect performance, the more soluble actives being leached out of the soil, before the crop canopy has sufficiently covered the soil surface to prevent a late weed infestation reoccurring.
In known deficient soils, manganese should be applied during November. Treatment of the condition before deficiency symptoms are seen will mean stronger healthier plants going through to spring. A follow-up treatment should also be applied in the early spring.
Scott Partridge, Monsanto Vice President
Like everyone else following the Dewayne Johnson v. Monsanto Co. trial, my colleagues and I have deep sympathy for Mr. Johnson’s plight. Our hearts go out to the Johnson family, and we understand their desire for answers.
Glyphosate is not the answer. Glyphosate does not cause cancer. The jury got it wrong. We will appeal the jury’s opinion and continue to vigorously defend glyphosate, which is an essential tool for farmers and others. We are confident science will prevail upon appeal.
The jury’s opinion does not change the science. Glyphosate has a more than 40-year history of safe use. Over those four decades, researchers have conducted more than 800 scientific studies and reviews that prove glyphosate does not cause cancer. The National Institutes of Health (NIH) and the Joint FAO/WHO Meeting on Pesticide Residues (JMPR) both recently reaffirmed glyphosate does not cause cancer. The U.S. Environmental Protection Agency (EPA) and other regulatory authorities in Europe, Canada, Japan, Australia, Korea, and elsewhere routinely review all approved pesticide products and have consistently reaffirmed that glyphosate does not cause cancer.
Rather than arguing the science, the plaintiff’s lawyers repeatedly crossed the line, distorted the facts and used baseless and egregious emotional appeals to inflame the jury. We are deeply troubled by the conduct of the plaintiff’s lawyers in this case. The judge admonished this conduct on several occasions and instructed the jury to ignore these statements. However, we are concerned that this conduct unduly influenced the jury’s deliberations, and we will be raising this issue in our appeal.
The plaintiff’s lawyers know they cannot win on the science. This lawsuit is based solely on the opinion of one organization called IARC. IARC is not a regulatory authority and did no independent studies. IARC is the same organization that determined beer, meat, cell phones, and coffee cause cancer. Investigative reports by Reuters (here and here) and the Times of London (here) have uncovered that IARC members reviewing glyphosate concealed important scientific data, edited out the conclusions of key studies, and were closely aligned with U.S. trial lawyers.
After IARC’s opinion was announced in 2015, U.S. trial lawyers starting running advertising campaigns to recruit people for their lawsuits against Monsanto. There were no lawsuits blaming glyphosate for cancer until after IARC’s opinion. A federal judge overseeing some of these lawsuits recently stated that plaintiffs’ evidence is “shaky” and any lawyer faces a “daunting challenge” in bringing a case to trial based on IARC’s opinion.
Our next step is to file post-trial motions with the Court. Following the Court’s ruling on the motions, we will file our appeal with the California Court of Appeals if needed. We are fully confident that science will prevail in the end. Glyphosate-based herbicides are too important to farmers and others for these baseless lawsuits to go unchallenged.
Words matter. As a professional communicator, I spend a tremendous amount of time working with words: determining which ones make the most impact toward a goal, aligning them to the tone and tenor of an occasion, organizing them to articulate a thought with clarity.
We put a lot of stock into words, as we should. Language helps us to understand the world around us and relate to one another. It’s also true that some words have baggage – thanks to their composition and/or history. Take the word “pesticide.” At first blush, it may sound like a scary word. It has the word “pest” and suffix “cide” right there, front and center, so it must be bad, right? Combine that with the fact that the conversation around pesticides is riddled with misinformation, and “pesticides” fall short of engendering warm, fuzzy feelings.
However, for the millions of farmers across the world who rely on crop protection, including pesticides, to deliver strong crops to help feed the planet, these products do critically important work despite their reputation in some circles. Every year, as much as 40 percent of the world’s potential harvests are lost to damaging insects, weeds and plant disease. Without crop protection tools and practices, the Food and Agriculture Organization of the United Nations says these losses would double. The results of that would be catastrophic.
There’s no single solution to crop protection, but pesticides are an important tool farmers can use alongside other common and effective practices, including cover crops, tilling, crop rotation and proper timing of planting.
The very real threat of losing crops means that most farmers – whether they employ organic or modern agriculture practices – use some type of pesticide to keep insects, weeds and plant diseases from destroying their crops. That may sound surprising, as there’s a common misconception that organic crops are grown without pesticides. That’s simply not true. Organic farmers must make tough decisions every day, too, including how to manage pests. And that includes the use of pesticides. To keep harvesting the food needed to feed a growing population, all farmers must protect their crops from threats in the field.
Despite their diminutive size, insects can leave behind a broad wake of destruction. An insect tinier than an apple seed spread a disease with no cure among orange crops a few years ago, leading to a $4 billion loss and another battle in the global war against food waste.
Insects aren’t the only culprit. People who enjoy gardening around their homes likely think of weeds as an unattractive nuisance, but invasive weed species play a more sinister role on farms. Weeds steal water, sunlight and nutrients from crops, harming their ability to grow strong and produce food.
Still, the idea of pesticides can make people nervous. “Aren’t those chemicals?” is a question I hear often. But we need not fear chemicals: The world around us is made up of chemicals, and the chemicals used in pesticides are heavily researched, validated and regulated. Before companies can make pesticides available to farmers, these crop protection tools must undergo comprehensive evaluations by regulatory authorities. Here in the U.S., the Environmental Protection Agency requires all pesticides to pass significant safety studies before they are approved. The regulatory involvement doesn’t stop there: The EPA routinely reviews registered products to ensure they continue to meet safety standards.
It’s easy to see how the myths about pesticides keep spreading. Like you, I want the best for my family. I want to feed my three kids safe and nutritious foods, developed by an agriculture system that protects our precious natural resources. Pesticides, even if they sound intimidating, make that possible. And for that, I am thankful. Without them, agriculture production will not be able to keep pace with the growing demands of society.
So what’s in a name? When you’re a communications professional in agriculture – sometimes a whole lot. But my colleagues and I are committed to championing facts over fiction, for pesticides and otherwise, when it comes to protecting the solutions that drive progress for modern agriculture and the people who are charged with helping feed the rest of us.
The drought during July has caused rapid senescence on many winter wheat and spring barley crops. A fair acreage of winter wheat crops have been harvested for whole crop. In order to ensure harvested crops are kept free from pests,stores need to be thoroughly cleaned to ensure any debris that may be harbouring pests is removed.Pests arise from within the store and not from harvested grain. Reldan can be applied to empty stores to combat grain store pests.
The recent rainfall will bring slugs back up onto the soil surface and there will certainly be a need to assess numbers for autumn planting. An easy way to trap is to use dry food such as breakfast cereal (muesli) or similar and place a tablespoon under a slate or fertiliser bag. Traps should be checked early in the morning approximately two days after being placed in the field. Slugs don’t like fine firm seedbeds so good cultivation can reduce the risk of damage as can deeper sowing. There are also some cereal seed treatments which can protect seed hollowing by slugs but damage to shoots remain a threat.BYDV protection can be given in seed treatment as well as takeall and autumn foliar diseases.
The risk of blight remains high with great variations in particular areas due to localised showers. To try and keep crops free from blight where pressure is severe requires short intervals appropriate for high risk and also the use of fungicide products with curative activity. Fungicides with good rainfastness will be very beneficial given the current showery conditions , especially because it’s been difficult to accurately predict the timing and location of showers.
Propionic acid has an energy value of 1.5 times that of barley so as well as preserving the grain it also adds to its energy value. With Propionic treatment, harvesting can take place when there is still surface dampness on the grain, dew or rain. Harvesting can start earlier in the morning or after rain and continue later at night, giving a quicker more flexible harvest, which leaves extra time for autumn cultivations. By harvesting before grain is fully ‘ripe’ a higher yield is also obtained, reduced shedding losses may save 200kg per hectare.
Natural vitamin E levels in moist grain, whether treated or not, are destroyed during storage. When moist grain forms a major part of the diet a mineral/vitamin supplement high in vitamin E should be used.
Treated grain can be stored simply on a dry floor. It should not be stored with untreated grain. Check MC and auger rate regularly.
