Late planted Corn

In Ontario and Quebec in 2011 we will have the majority of the corn planted after the optimum date of May 10th. What does this mean and what should our expectations be?

At the time of writing this (May 18th) it appeared we would be at least a couple of days before we could be back planting. Should we switch hybrids? I would recommend in the shorter growing season areas (<2750 CHU) switching now (drop 100 CHU per week delay but do not go below a 2600 CHU hybrid) and for mid range (2800 – 3000 CHU) switch around May 25th and rest of the area's do not switch until June. (reference: Switching to Earlier Hybrids).

What should we expect for yield this fall due to the delayed planting conditions this spring? First remember many other factors still affect yield other than planting date such as fertility, population, hybrid selection, weather, seed depth, compaction, etc…

Yield : expect to lose one bushel per day delay from May 10th or around 10% if delayed until June.

Harvest Moisture: On average expect one point of moisture increase for every four days delayed from May 10th. If delayed to early June a five point increase or 30% moisture compared to 25% if planted early.

Test Weight: Long term average is one pound of test weight loss for every 10 days delay in planting or 2 lbs if delayed to early June.

What can we expect if delayed to early June? 20 bu per acre ($100.00 per acre) plus on an expected 150 bu/ac crop $0.20/bu drying cost increase (assumed drying $0.04 per point per bu) equals $26.00 per acre. Assuming we do not lose grade due to reduced bushel weight a delay until early June could end up costing $126.00 per acre at $5.00 per bushel corn.

Let’s hope for a break in the weather and get this corn crop into the ground.

Calling all Western Bean Cutworm Scouts

If you are planning to scout for this important pest this year make sure your counts are sent into WBC Trap Network in Ontario. For information on how to do this please visit Baute Bug Blog.

Agrisure Viptera Experience

I had a chance to sit down with Grant Ozipko, Agrisure Trait Marketing Manager to discuss the results of Agrisure Viptera in the US and the new traits from Syngenta Seeds. Youtube link
A number of US growers had a chance to grow and see Agrisure Viptera 3111 in 2010 through Agrisure Experience Program. This gave them firsthand experience with the control of Agrisure Viptera on pests such as corn earworm, western bean cutworm and black cutworm on their farm. They were so impressed many of them came back this year and purchased hybrids with Agrisure Viptera trait for the 2011 growing season.
Why should I grow Agrisure Viptera? Peace of mind that you have a product that provides more control of more insects than any other product on the market. What can we expect for control and yield results? Syngenta testing has shown Agrisure Viptera had a yield advantage of over nine bushel per acre across all trials in 2010 when compared to smartstax products.

Agrisure Viptera will be the foundation of refuge reduction products from Syngenta. For Canada registration is expected for a refuge reduction product in 2012. It will be called Agrisure 3220 which gives two modes of action against broad lepidopteran insects and two modes of action against corn borer. It is this product that will allow reduced refuge and ultimately a refuge-in-a-bag product (when approved).

What is in the Agrisure pipeline? The pipeline has a full line of refuge reduction trait stacks including that can be used in rootworm areas. Agrisure Artesian is Syngenta water optimization platform that uses multiple traits to provide hybrids a chance to manage drought throughout the season.

Thanks Grant for your time.

Not all Genes for Western Bean Cutworm the same

We have seen the same results as described in the article attached. Under significant ear-feeding insect pressure, hybrids containing the Agrisure Viptera 3111 trait stack averaged 7.3 bu/ac better than hybrids with the Agrisure® 3000GT triple stack. In fact, hybrids with the Agrisure Viptera 3111 stack outperformed their Agrisure 3000GT stack counterparts in all geographies and insect pressures, delivering a 4.4 bu/ac yield advantage.
“Our 2010 trials included a range of geographies and a range of pest pressures,” says Bruce Battles, head, Agronomy Marketing with Syngenta. “We saw clean ears from the Agrisure Viptera trait in all of them, but of course the difference was most pronounced in plots that experienced heavier pressure. In those instances, there was no question which trait package was delivering better control.”

As compared to other competitive traits, the products with the Agrisure Viptera 3111 stack out yielded Pioneer® brand hybrids by an average of 9.7 bu/ac. The trials also demonstrated a 9 bu/ac yield advantage versus competitive DeKalb® brand Genuity™ SmartStax™ offerings, and 12 bu/ac over competitive DeKalb hybrids with the VT Triple PRO™ trait stack.

Picking the right hybrid for next year?

Rushing to put an order in to get the best deal is now the norm for the corn seed industry. So how do i make a decision when I have either just got my crop off the field or I am in the middle of harvest. It is difficult. This is where you really need to enlist the help of your corn dealer and company rep. Genetics is the most important production management decision you make every year. Why do we rush it? We do not know exactly what field we are putting corn into for sure yet. So how do we get this right to make the most money for your farming operation?
1) View the early order and pay as a way of securing seed supply for a number of acres. As an example – I am going to grow 400 acres of NK corn and 600 acres of NK soybeans (RR2Y) and the other acres I am going to grow a competitor. Then as a grower let your seed rep put the best package together for your farm for today based on what he knows. This allows you time to modify your order and put the correct genetics on field(s) they are adapted as you do your crop planning during the winter months. Orders can be adjusted if seed is available to allow you to grow your best crop ever.
2) Every year is different and this fall does not predict the results you will get next year. You need to use multi-year, multi-site data and do not fall into chasing the ‘hot hybrid’.
3) Select a package of diverse genetics and agronomic traits. You need high yield products to maximize your total overall yield average, plus average yield hybrids that have above average late season standability to maximize your harvest window, specialty (or niche) hybrids that excel on those special fields or conditions (corn on corn, drought soil, low productivity soil) to maintain yield in tough environmental conditions and you need economical products that yield in your operation to lower your overall cost of production.
4) Select genetically diverse products to spread risk. This is a ‘do not put all your eggs in one basket’ approach to manage the unknown growing environment for next year.
5) Remember you are selecting hybrids for next year‘s growing season not this year’s growing season. Often we get caught up in this year’s results rather than trying to get the best hybrid mix for what next year will bring. Anyone can predict the past; it takes skill and work to manage the future.

Every year is different. There is no perfect hybrid. Take you time in one of the most important decsion you make.

Multi-Pest Complex Control – Agrisure Viptera 3111

Over the past couple of months we have shown multi-pest field tours for western bean cutworm and fall armyworm. At Syngenta we inoculated western bean cutworm on an Agrisure Viptera 3111 hybrid and a non-Agrisure Viptera 3111 hybird in 2010. Here is the field tour of the plot by Nick Cowan, Techinical Product Specialist and what we saw.

Western Bean Cutworms moth #’s dropping — but look for larva

Contributed by Robert Moloney, NK Brand Seeds

Catches of Western Bean Cutworm (WBC) moths are rapidly dropping to zero across the province as of this week.  At this point we wouldn’t expect moths to be laying eggs anyway, but the overall catch numbers for the year give us an idea of how big and widespread the problem has the potential to become.  Even taking into account the fact that there were many more WBC moth traps in Ontario this year versus previous years, the number of moths caught increased massively this year.  We will have to wait for corn harvest to get a better handle on just what this means for the damage we may see in Ontario this year, but it isn’t difficult to find larva in corn ears in areas with high moth capture numbers now (see previous blog entries for details on scouting for larva).  The larvae are very mobile, so even if you couldn’t find the low numbers of egg masses in the field earlier, you may be able to find the larva and damage now.  In plots at the NK Arva research station which had egg masses moved into them to ensure infestation of WBC it is not uncommon to find larva in every cob within 6-8 feet of row from the marked plant that the egg mass was attached to.  In some spots they have moved even farther than this.  The positive news is that plants with the Agrisure Viptera 3111 trait that also had egg masses attached to them are showing no signs of WBC damage or larva survival.

Why scout for larva?

At this point in the season we can’t do anything to control the WBC larva in the cob but it is still worth scouting your fields to get an idea of what level of WBC larva pressure you have in the field.  This will allow you to prioritize fields with higher potential for ear mould growth for earlier harvest.  In some fields we are already seeing some ear mould development where WBC have been feeding.
