Australian Report – Peanut Planting Time

Posted by romeethredge on December 14, 2015

Our weather is warmer than normal but we aren’t planting peanuts like they are in Australia, although it feels like we could.

I have an Australian fellow agronomist friend, Neil Halpin, who does research concerning peanuts and other crops. It’s funny that emails from there are often dated tomorrow’s date. Even right now it’s 9:19 in the morning here on Dec 14th, in his town of Bundaberg it’s already tomorrow, 12:19 am, Dec 15th.

He visited us here several years ago. He was kind enough to send us this report concerning what’s happening there at planting time down under.

 

“The Coastal Burnett cropping area is located around the towns of Bundaberg, Childers and Maryborough in Queensland Australia. The cropping is dominated by sugarcane. We have around 47,450ha (117,201 acres) of sugarcane. We also have about 5,800 ha of macadamia trees and about 1,000 ha of avocado trees as well in the region. Due to our sub-tropical climate we can grow a wide range of horticultural crops like tomatoes, capsicums and sweet potatoes to name a few.

Peanuts and soybeans are an excellent rotation crop for sugarcane. We have at least 80% of our peanut crop planted. Our area planted to peanuts is down to around 1,000ha this season. The reduced planting is a result of a poor season last year where grades and therefore prices were very poor. Pictured below is a recently emerged crop, however some other crops in the district are 10 weeks old.

We are expecting to have at least 2,000 ha sown to soybean this season. Some have been planted but many growers are waiting on some rain that is predicted in the next few days. Now is the ideal planting window for soybean so I hope we get lucky with the rain. Below are some growers inspecting the planting depth of their soybean seed.

Our average rainfall is around 1,100mm or 44 inches. Whilst the rainfall is summer dominant many of our soils have low water holding capacity so irrigation is essential. More attention to detail is generally paid to the peanut crop as it is a higher input crop. Due to the lower value of soybeans, growers tend to irrigate soybeans a little less frequently than peanut crops in our district. As a rough rule of thumb it costs us $200/ML to irrigate crops. Typically we would use 4ML/ha of irrigation on our peanut crops. A ML = 100mm (4 inches) on a hectare (2.47 acres).

Anyway we are hoping for a good legume cropping season as sugar prices are pretty low for our growers.”

 

Here is where Neil is located.

Peanut Field Sink Hole

Posted by romeethredge on December 11, 2015

We have the Floridan Aquifer under us and it’s got some small underground caverns or groups of holes in some spots and when we get lots of rain the water level rises and then perhaps falls and breaks some areas loose and holes can develop.

Calhoun County Farmer, Jimmy Webb  had one appear after digging peanuts but before picking them. I saw it on Twitter and I posted some photos below.  This happened in early November when we got so much rain. Jimmy said they got 9.3 inches of rain in 10 days

I believe this link will take you to Jimmy’s Twitter video of the sinkhole –   pic.twitter.com/rAQqgsvddI

Peanut Disease Bad In 2015

Posted by romeethredge on November 13, 2015

I think 2015 was definitely one of the worse peanut white mold ( Sclerotium rolsfii) aka southern stem rot, years in history. High heat and frequent cloudy rainy periods caused it to be worse than usual.  It was definitely a year that premium white mold products paid off.

FullSizeRender (3)

Here’s some comments from Dr. Bob Kemerait, UGA Extension Plant Pathologist, concerning white mold this year and what we can do.

  • Why do I have so much white mold in the field and did I get ANYTHING from my fungicide program?

Answer:  I have been asked this question again and again, over and over this season.  First, here are a few things to remember.  The 2015 season has been very favorable for white mold, pushing all of our fungicide programs to the limits of performance.  No program, no matter how much you spend, can control all disease in a field.  I think 75% control may be all we can get sometimes.  Couple warm temperatures with dry conditions and our dryland fields are, well, you know what I mean.  Without rain or irrigation to wash the fungicides to the crown of the plant, performance and control are reduced.  Our huge peanut acreage must mean that some of our fields are on a short rotation.  Short rotation, hot temperatures and perhaps over-reliance on tebuconazole because of low peanut prices all add up to a white mold “field day”.

How do you know if your white mold program worked for you?  If you look out in a field and see a number of white mold “hits” you are likely to be disappointed.  However, if such “hits” are contained to a one, maybe two plants and do not extend in streaks down the field, then you can be confident that your program was engaged and fighting for you.  Also, if finding active white mold is difficult, then you can also be confident that your program was working for you.  Note, however, that managing underground white mold is especially difficult because of getting the fungicide to the target below the soil surface.  Underground white mold is difficult to control, even under the best of circumstances.  Control may be improved with timely irrigation or rainfall, or by spraying the crop at night.

  •  Is there anything I can do now to prepare for disease management in peanut next season?

Answer:  Yes, there are several things.  First, do your best to increase the number of years between peanut crops in a field.  Second, identify the diseases that have been most problematic in your field and work with your county agent to develop a comprehensive management plan to include choice of variety and fungicides.  Educate yourself on fungicides that are available now and those, such as Elatus, that will be available in 2015.  Lastly, consider taking nematode samples and preparing for nematode management in 2016 with resistant varieties (Tifguard and Georgia-14N).  Also, note that our current predictions are for a strong El Niño this winter, bringing increased rainfall and cooler temperatures.  Growers should anticipate how such will affect disease management in all of their crops to include delays in planting or in application of Telone II.

Cold Weather and Peanuts

Posted by romeethredge on October 23, 2015

When we have 3 or more days with low temperatures in the lower 40’s  the peanut maturation process will shut down. When this happens and you have fields left to be harvested you can be making plans to begin harvest as soon as the colder mornings pass.

 

Here’s Alex Johnson with some real good peanuts recently harvested near Reynoldsville.

IMG_9065

DO NOT DIG the day before a morning in which the low temperature is low enough that there is a risk of frost or freezing. Keep in mind, the recorded low temperature is measured at 5 feet above ground by the NWS. Cold air sinks, which means it could be a few degrees colder in low lying areas of fields.

Frost or freezing temperatures on freshly dug peanuts can cause freeze damage to the kernels, which in turn, can be graded as Seg 2 peanuts. Seg 2 peanuts are greatly devalued when graded. If a field is dug on an afternoon and we approach the middle 30’s in temperature the next morning, freeze damage can occur. When dug, peanuts have 40% or greater moisture. Two or three days in the dug windrow allows the moisture content to drop enough so that the seed separates from against the inside of the hull. This separation will alleviate the risk of freeze damage. High moisture content with a seed still in contact with the inside of the hull increases the risk of freeze damage.

Nematodes in Peanuts and Thanks to WTVY

Posted by romeethredge on October 21, 2015

It’s a good time to evaluate peanut fields here at harvest. Just after we dig our peanuts is a good time to evaluate our nematode control. Sometimes we see that we have peanut rootknot nematode problems in a field that we didn’t have a problem in before. It is important to note this so that the next time we have peanuts or a susceptible crop in the field then we can take action to prevent yield loss due to this pest.

I recently recorded a TV spot where I talk about peanut nematodes.

Since this was my last scheduled appearance on the “Focus on Ag” segment on WTVY 4 in Dothan , I thank them for doing a good job covering Ag stories and promoting Ag awareness. I’ve been talking about Agriculture on WTVY for over 20 years starting with Gene Ragan on his farm show.

Peanuts Burning

Posted by romeethredge on October 16, 2015

We’ve lost a nice peanut warehouse in Donalsonville to fire. It’s the old Beall Peanut Company warehouse, that had a capacity of a whole lot of peanuts. Reports are that it was pretty full of this year’s, just harvested, peanuts belonging to Session’s Peanut Company.  It’s close to downtown and our Extension office, (see photo). The  fortunate thing is that there have been no reported injuries or fatalities. Firefighters and public safety officers are doing a good job keeping things contained .  It started about noon yesterday and this morning there is still a lot of smoke coming out of there and the whole town smells like burnt peanuts.

Here’s several photos from various sources. Wade Spooner sent me the aerial photos.

Peanut Situation in South Carolina

Posted by romeethredge on October 12, 2015

Peanut Situation in South Carolina

We feel for the South Carolina folks and here’s a peanut situation update from Extension Scientists there, Jay W. Chapin and Dan Anco.

“Only about 10-15% of the peanut crop was picked before the storm hit. Yield and quality was highly variable due to previous drought stress.  We had instances of 5000 lb+ high quality irrigated Virginias directly across the road from 1500 lb Seg. 3 drought stress.  We also had some very good dryland yields.

None of the following harvest comments refer to fields that are under water or washed away.  Obviously we are going to have some 100% losses in entire fields and field areas.  There has been some concern about harvesting these drown, rotted areas and mixing them with better higher ground peanuts.  But this should be limited just by the fact that we are not going to be able to go through the bottoms for a good while anyway and growers won’t wait around to get the ones they can get to.

Out of the unpicked peanuts, about half, maybe a bit less were dug.  The peanuts that had already weathered above ground for two weeks or more in the showers, mist and temperatures in the 80s are at high risk of pod loss at the combine header.  Most of these won’t stand lifting; it will be tough enough to pick them up one time with the combine without losing some of the best pods.  They also have greater risk of Seg. 2 from potential mold.

In contrast, peanuts dug the week before the storm should retain their quality and the vines will stand lifting.  These are a higher priority to lift and pick as soon as we can stand up.

Roughly 45% -50% of the crop was still in the ground, but growers were back digging by Wednesday (6 Sept.) in areas like Marion and eastern Orangeburg Cos. – above and below the worst of the storm.  Most of the crop that is still in the ground is already mature or over-mature.  Over-maturity digging losses will be severe where we can’t get to them for another week, or much longer in some areas.  Over-mature peanuts and wet soils are a bad combination.

Finally, we have some later planted or previously drought stressed runners that will mature late enough to not be affected by the storm.  We can wait for more ideal soil moisture for digging.

The harvest priorities are pretty clear-cut in non-flooded areas where growers can operate. Focus on picking the higher quality fresh vines and digging mature fields whenever soil conditions allow.  A lot of the deteriorated vines will have to dry without lifting.  We can’t worry about the digger getting even further ahead of the combine where we already have mature peanuts in the ground.  We have about a three week window left of normally good – excellent harvest conditions.

All this is easy to talk about; very tough to get done.  Growers in flooded areas have concerns other than getting the peanut crop out; transportation is a big problem with loss of roads and bridges.  It has been a very difficult year, but the peanut industry in South Carolina has a good future.  All of the investment in buying points, production equipment, irrigation, and management capability is still intact.  Peanuts have had a more positive impact on row crop farm profitability over the past decade than any other crop in our state and can continue to do so over the long haul.

Rain Delay

Posted by romeethredge on October 9, 2015

We felt like we were watching a great baseball game and then went into a long rain delay. Picking peanuts was delayed for 2 weeks in some cases. We also had heavy rains in many areas that stopped digging as well. The field below was wet and you can see how a three inch rain washed the peanuts around that had been dug.

Here’s a different field with peanuts washed around.

 It was agonizing but now thankfully we are seeing some sunshine.  Thanks to Brad Thompson for taking me flying so we could survey the damage.
