What chemicals are allowed on hemp?
Most herbicides and pesticides are not labeled for hemp. rechem's chemicals are organic, and they go on early.
What chemicals are allowed on hemp?
Most herbicides and pesticides are not labeled for hemp, so a corn or bean program does not transfer. rechem's chemicals are organic: a seed treatment, field enrichment before planting, and support for the young stand. The HFGA textile standard also refuses unlabeled crop protection and pre-harvest desiccants, including glyphosate.

What is plant immunotherapy?Plant immunotherapy is rechem's name for organic chemistry that helps a crop defend itself. Pesticides, in this framing, are chemotherapy for the field.
Heartland's account is the short one: most pesticides and herbicides are not labeled for hemp. If it is not labeled for the crop, do not put it on the crop. A corn or bean program does not transfer.
rechem's chemicals are the other list. They are organic. They are not a herbicide program and not a rescue-spray calendar. They are a seed treatment, field enrichment before planting, and support for the stand after it is up. That is plant immunotherapy: help the crop, and leave the soil able to work. The comparison is What is plant immunotherapy?. This page does not add a USDA or EPA registration the company has not stated.
The textile standard
The HFGA US Hemp Textile Standard is stricter still for fiber that has to meet it. No crop-protection product without an EPA label for hemp, for the twelve months before harvest. No pre-harvest desiccants, including glyphosate. Total delta-9 THC at or under 0.3 percent on a dry-weight basis, from a sample drawn within 30 days before harvest.
Those products labeled for corn or beans stay on corn or beans. HFGA's textile standard treats an unlabeled pass as a failed lot, not a paperwork detail.
Fertilizer, seed treatment, and drift
Less nitrogen drama than the crops hemp often replaces. Heartland describes hemp as needing minimal nitrogen, which is one reason they talk about it for organic acres. HFGA points farmers at a fertilizer package, and it does not publish that package as a universal rate. rechem will talk about enrichment of the field before planting. That note is How do I prepare a field for hemp?. A copied corn fertilizer bill is not a hemp plan.
What goes on the seed is rechem's seed treatment, written up as Organic seed and planting chemistry. Anything else on the seed needs a reason that survives the "is it labeled for hemp?" test.
If spray drifts in from next door, treat it as a contamination problem. A product that is not allowed on hemp is still not allowed because it arrived on the wind. Tell the buyer and the state program what landed, and when. A drifted desiccant can cost the lot.
FAQ
Quick answers about this part of the approach.
Can I spray my corn herbicides on hemp?
No. Those products are labeled for corn or beans. An unlabeled product does not become allowed because it worked on the last rotation.
What does rechem put on the crop?
Organic chemistry. A treatment on the seed, enrichment of the field before planting, and support for the stand after it is up.
Are pre-harvest desiccants allowed?
Not under the HFGA textile standard. That includes glyphosate. The standard also refuses any crop-protection product without an EPA hemp label in the twelve months before harvest.
What fertilizer does hemp need?
Heartland describes hemp as needing minimal nitrogen. HFGA points at a fertilizer package and does not publish it as a universal rate. A copied corn bill is not a hemp plan.
What if spray drifts onto the field?
Treat it as contamination. Tell the buyer and the state program what landed, and when. A drifted desiccant can cost the lot.
