Japanese Beetles Attack!

A lot of our field and vegetable crops are now being attacked by Japanese Beetles, see photos. They consume the leaves of many crops, such as corn, soybeans, snap beans, tomatoes, melons, etc. Please check your fields now or contact one of our Allied Cooperative agronomists to assist you.

Soybean Aphid Alert!

Attention! Soybean Aphid Alert! Soybean aphids have started to hit our area. We found out some fields are at threshold. I just visited with a grower whose fields are in Southern Adams county and Northern Columbia county and he has soybeans fields that need to get sprayed. Be sure to use a minimum of 15 gallons of water and a lot of pressure to get good coverage. I have had very good results using Leverage 360 insecticide in the past at the 2.8 oz rate. If you are spraying the field consider tank mixing in a foliar micronutrient package, such as Max in ZMB, and/or a foliar fungicide such as Stratego YLD at 4 oz. Please contact one of our agronomists to find the best recipe for your acres. Thanks and be safe out there!

UPDATE (5:36pm): In talking with our team up in Galesville this afternoon it sounds like the Soybean aphids are very bad up on the Trempealeau Prairie, just west and a little north of our Galesville location. They are ordering in more Leverage to combat this pest. Please check your fields on a regular basis. Typically the threshold is at 250 aphids per plant.

Watch for insect damage and topdress your fields correctly!

Over the next couple weeks, it will be very important to keep an eye on your fields for insect damage and to topdress your fields with the correct recipe.

With the increase in temperatures, we need to keep a closer eye on our crops for insect damage. Yesterday one of our scouts, Bryan Decker, sent in some photos of some insect damage in northern Adams county.

Also with the constant flushing of the soil profile we are encouraging growers to evaluate fertility shortfalls in their crop ASAP. When the need is established, a liquid or dry fertilizer recipe should be developed and applied to the field as soon as possible. A lot of our corn is at or past the V6 stage, when the number of rows around is established. We want to make sure that our corn has all it needs at this critical stage. Also in preparation for the rapid growth phase, V8 to VT, the plant is going to be taking up a lot of nutrients. Our agronomists have done a lot of tissue testing this past week and a lot of the samples are showing some deficiencies. The major nutrient deficiencies are Nitrogen, Potassium, and Sulfur. Some micros that have shown up as low have been Zinc, Manganese, and Boron. If you are topdressing your corn please make sure you are putting together the appropriate recipe for your fields. Contact one of our agronomists to assist you in this process. Thanks and have a safe Fourth of July!

Armyworm damage found today! Watch your fields!

Armyworms found today north of Adams near Coloma. Please check your fields for this pest, they will move FAST with this heat. Let us know if you need any help checking your fields. If you are seeing more than 8% damage I would encourage you to spray an insecticide such as Arctic at 6 oz per acre ASAP. Contact us for more details!

Insects attacking our alfalfa fields!

We scouted a lot of our producers’ alfalfa fields today. Second crop is well on its way and we are finding some insect pests. The potato leafhopper is one of the most damaging pest to alfalfa in Wisconsin. I looked at a number of fields today that will need to get treated very soon to take care of this troublesome pest. Also with first crop off, now is a very good time to topdress second crop with a mixture of Potash, K-Mag and Boron. Please get a hold of us for a recipe that will best fit your fields.

More wet weather this week (June 10-14)

More wet weather ahead in the forecast makes for tough hay drying weather, and more rain is the last thing we need on some of the wetter ground that we have been waiting to plant all season long. Also, this cool wet weather favors pythium in the soybeans and we have been finding some dead seedlings in several fields across the area.

In the potatoes, the second hilling is getting finished up and fields should be checked for weed escapes. Also, Colorado potato beetles are laying eggs in full force, expect the first generation of larvae to emerge next week. The black light traps are extremely quiet right now with only a few cutworm moths.

Looking forward into the future, consider doing some nematode testing on your farm this year. Nematodes are microscopic worms that exist in almost all soils and, while many are harmless or even beneficial, there are several plant parasitic nematodes that may be secretly robbing yield year after year. Many of you are probably familiar with soybean cyst nematode, but there are many other nematodes that affect other crops. Nematodes that are particularly damaging in corn are dagger, lance, root lesion, and needle.

At Pest Pros, a division of Allied Cooperative, we sample and test soils for nematodes to measure a fields relative risk for nematodes in the future. Such information can help you identify and begin to manage a nematode problem. Sampling can also help you asses your Poncho/Votivo and Avicta programs. For more information on nematode testing, contact the Pest Pros lab at (715) 335-4046.

Dealing with wet fields, weeds, and pests this week (June 3-7)

This week is shaping up to be a wet one which is a problem for some of the fields that are weedy and too wet for us to get into to spray. Consider increasing rates, and heating up your tank mixes for better weed control on taller weeds when you do get into these fields later. Continue to be vigilant in looking for black cutworm clipping of corn.  The threshold is 3% of plants clipped to warrant a spray. In the potatoes, the first generation Colorado beetles are laying eggs so look for newly hatched larvae next week. Do stem and stand counts this week to determine populations, and weed scouting to see if the hilling operation missed any weeds. Watch out for common ragweed especially as they are very difficult to control if they get larger than 2 inches.

Crane Damage and a Cutworm Alert!

We saw two big issues in fields today!

First, crane damage was seen just north of Adams today! Keep an eye on your field for crane damage! Look at the picture below – the cranes pulled the plants right out of the ground.

Second, cutworms were found feeding just south of Adams this morning. Please check your fields or give us a call to help scout your fields ASAP, so that these pests don’t chew up your crop.
