Abstract
The present invention relates to a herbicide formulation based on pine oil. The present invention also relates to a method of reducing unwanted vegetation in a soil environment and a method for reducing seed viability using the herbicide formulation. The herbicide formulation comprises a pine oil, a tall oil, and an alkali. The formulation has improved herbicidal properties, and is less subject to coagulation at low ambient temperatures.
Claims28
An organic herbicide product comprising:
- low lignin content pine oil about 48%-75% (w/w);
- low to medium rosin tall oil about 19.4%-23% (w/w);
- and
- KOH about 4%-8% (w/w);
- wherein the pH of the product is about 10 to about 11;
- wherein the low lignin content pine oil comprises less than 1% (w/v) lignin;
- wherein the low lignin content pine oil comprises hand-tapped pine oil;
- wherein the low to medium rosin tall oil is a tall oil with 30% (w/w) or less rosin acid;
- and
- wherein the organic herbicide product does not contain NaOH.
A method of reducing unwanted vegetation in a soil environment comprising:
- spraying the soil environment with an effective amount of an organic herbicide product comprising:
- low lignin content pine oil about 48%-75% (w/w);
- low to medium rosin tall oil about 19.4%-23% (w/w);
- and
- KOH about 4%-8% (w/w);
- wherein the pH of the product is about 10 to about 11;
- wherein the low lignin content pine oil comprises less than 1% (w/v) lignin;
- wherein the low lignin content pine oil comprises hand-tapped pine oil;
- wherein the low to medium rosin tall oil is a tall oil with 30% (w/w) or less rosin acid;
- and
- wherein the organic herbicide product does not contain NaOH.
A method for reducing seed viability comprising:

- and
- wherein the organic herbicide product does not contain NaOH.
A process for preparing an organic herbicide product, the process comprising mixing at ambient temperature for a time sufficient to cause saponification:
- low lignin content pine oil about 48%-75% (w/w);
- low to medium rosin tall oil about 19.4%-23% (w/w);
- and
- KOH about 4%-8% (w/w);
- wherein the pH of the product is about 10 to about 11;
- wherein the low lignin content pine oil comprises less than 1% (w/v) lignin;
- wherein the low lignin content pine oil comprises hand-tapped pine oil;
- wherein the low to medium rosin tall oil is a tall oil with 30% (w/w) or less rosin acid;
- and
- wherein the organic herbicide product does not contain NaOH.
