## Abstract

Disclosed are compounds having a monoterpenoid and/or phenylpropanoid moiety and methods of their making and use as pesticidal compounds, such as herbicides.

## Claims

### Claim 1

An herbicidal composition having systemic phytotoxic effects, comprising:
a. an active herbicidal compound consisting of thymyloxyacetic acid or methyl thymyloxyacetate, present in 0.5% to 5% by weight, based on the total weight of the herbicidal composition; and
b. a carrier comprising water and potassium hydroxide, wherein the potassium hydroxide aids in solvation of the active herbicidal compound and is present in a 1:1 molar ratio with the active herbicidal compound.

### Claim 2 (depends on 1)

The herbicidal composition according to claim 1, wherein the active herbicidal compound is methyl thymyloxyacetate.

### Claim 3 (depends on 1)

A method for controlling or killing dicot weeds, comprising the step of: applying an effective amount of the herbicidal composition according to claim 1 to the dicot weeds, wherein the dicot weeds include pigweed, velvet leaf, dandelions, or lamb's quarters.

### Claim 4 (depends on 3)

The method for controlling or killing dicot weeds according to claim 3, wherein the herbicidal composition is applied directly to the dicot weeds in a foliar spray.

### Claim 5 (depends on 3)

The method for controlling or killing dicot weeds according to claim 3, wherein the herbicidal composition is applied to the soil adjacent to the dicot weeds.

### Claim 6 (depends on 1)

A method for controlling or killing unwanted vegetation, weeds, or grasses comprising the step of: applying the herbicidal composition according to claim 1 directly to the leaves of the unwanted vegetation, weeds, and grasses in a foliar spray or to the soil adjacent to the unwanted vegetation, weeds and grasses.
