Was out crop checking and noticed my large green lentils are thin on my hill tops.
This is on Sandy ground. I thought maybe it was too dry but after doing some digging I find there are lots that are curled up and not going up. There is no crust, just soft fluffy soil. They are packed in good. Seeded fairly deep 2" or a bit better.
The lower ground they seem fine.
Any ideas what's causing this?

Did you use pre emergent?

Ant...

I would be curios to know the previous 2 years of herbicide applications.

 

[tsaskcan]

looks like chem carryover to me

 

[mbfarmer]

+1. Herbicide residual.

I'd say pre em wash in..chem carry over should have affected the low spots as well to a degree...decent rain event after pre em on lighter land can be nerve racking...maybe the chem stuck in the sandy soil more....

Disappointing for sure...

Large greens 2 years ago, used heat and glyphosate preseed, then centurian(clethodim), dessicated with glyphosate.
Last year barley, used glyphosate for preseed, then occtain and acheive in crop.
this year glyphosate and heat preseed so far.

And no rain on the field this spring until last night had a little thundershower that maybe gave .25 inch

I wonder if it could be the heat https://agro.basf.ca/West/Products/Heat.html
I used the recommended rate for lentils, but maybe since its so sandy it was still too much?

I would guess the Heat. Since I'm from the states I had to go look up the active ingredient. Same as Sharpen (saflufenacil) here. What rate did you use? It needs rain to activate so even a low rate may cause damage if there is no time to break down. My book here shows the plant back for lentil is 0 to 1 month (read variable). Microbial activity slows down if the soil is too dry so -> then less herbicide degradation.

Could it be fertilizer damage? Lots around here on hill tops.

 

[f_armer]

I wouldn't think so. ..but I don't know. I only put 45lbs of 12 51 0 with them

any chance that the seed had been treated with pre harvest glyphosate? Its not the problem if only showing up in the hill tops but the way the plants are snaking around and not heading "up" is pretty classic glyphosate damage of the embryo

I would say not, these are from a field that I sprayed part of with reglone, and part with glyphosate. The seed came from the reglone part, I'm not saying its 100% but should be close.

About 10 years ago a fella I knew got the Reglone and Roundup bins mixed up on peas.
Total catastrophic failure of the pea crop.

That would be bad. But in this case I know I used the right bin☺
Is just the hilltops also. I think it has to be related to chemical injury. Kinda weird though.

Glad it's only that.

What was the rate of HEAT?

 

[f_armer]

What was the rate of HEAT?

Used heat LQ, 21.4ml/ac, or 80 ac/case. With .5 liter transorb (270gr/ac)

 

[mbfarmer]

How long after planting did you spray the heat? They like it to be pretty soon after. I have gotten away with it just prior to emergence lots on clay loam soils.

 

[f_armer]

I sprayed before seeding them....
