Back to peas again, but maybe not too soon in the rotation?

Pretty much all of the broad leaf chemicals you spray on cereals will leave the tank and the booms with the same residue. The merge in the odyssey, viper, and liberty type chemicals will lift the residue off and out the booms it goes. We even buy the merge seperate and mix it with rince water and leave it a couple days in the tank and booms to help clean it out.
These companies dont want to even talk about sprayer residue because they know that some are impossible to clean out. Couple of lawsuits around here the last couple of years and they settled with non disclosure agreements so others would not find out.

****....the way I post you'd think I was a paid shill for BASF!

Steller, axial, prepass, are florasulam based chemicals they are some of the worst to blame, Basically its group B chemical damage. You can get your damaged peas residue tested. When our field had resudue damage we tested and it had florasulam damage. The roots turn brown and the tops are yellow and stunted.

I want to make something clear, this is not a debate, it's a discussion on my part. I am NOT balking anyone's responses, it's all good food for thought.

So how do I explain all the irregular patches in the field? Why wouldn't herbicide damage be more of a blanket of symptoms than a patchwork of symptoms?

And thank you everyone for contributing.

If it was residue in the soil it could break down faster in some areas and others. It would be pretty tough to tell the difference between chemical damage and disease unless you were to Tissue test.

Does the stress of the chemical or its unintentioned residuals create the problem of disease.?

[the big wheel]

Inconsistent nutrients could cause patches. If plants are stressed and not able to aggressively seek nutrients or nodulate, areas in a field rich in nutrients will keep plants going while other areas with low nutrients the effects of rain or disease is amplified. At least that's what I had one year according to tissue and soil tests taken in a good area and a bad area of crop.

I thought express was registered for peas if you seeded deeper than 2 inches.?????

it is ,(express sg) have done it. but. they are talking about a sprayer residue getting sprayed on pea plants from a poorly washed sprayer

When group 2 Glean was introduced to the western market they soon found such a persistent product in our high PH soils caused all kinds of residue and resistance selection problems.

More recently "stacking" group 2's of unrelated trade names ( eg; Express and group 2 Wild oat prod )
cause unexpected carryover issues IE: significant crop damage.

Group 2's are great products.

Using them for profit is more of an Art than a Science.

Soil PH isn't at all uniform throughout your fields as the brush cover wasn't uniform when great- grandpa broke it up.

Definitely chemical damage will weaken a plant enough to make it allot more susceptible to disease.
