摘要

This invention provides low-dose, low-concentration formulations of phytotoxic trace inorganic compounds for use in methods and systems for selectively and effectively controlling invasive plants.

主权项

1. A modified geochemical soil effective in the growth of an existing desirable perennial grass community in the soil, and selective in the phytotoxic control of at least one invasive species in the soil selected from the group consisting of cheatgrass, dandelion, and spotted knapweed, said modified geochemical soil comprising an elevated level of soluble boron in the soil, wherein said elevated boron level is produced by applying boron to an area of the perennial grass community to achieve a soluble boron concentration in the soil of the perennial grass community of about 3 milligrams per liter to about 50 milligrams per liter.
