is today an increasing problem in the BLM Rawlins field
This practice is very effective in wet years, but it makes the perennial species very susceptible to dry conditions and stimulates the growth of annual weeds such as Halogeton
infests rangeland in seven western states.
Plants in the genera Halogeton, Rumex and Oxalis show high levels of oxalate accumulation.
They include setaria, halogeton, soursob (Oxalis spp.), pokeweed (Phytolacca americana), purslane (Portulaca oleracea), lamb's quarter (Chenopodium album), bassia (Bassia hyssopifolia), greasewood (Sarcobatus vermiculatus), pigweed (Amaranthus spp.), Russian thistle (Salsola kali), sugar beets (Beta vulgaris), rhubarb (Rheum rhaponticum) and various others (Jones et al., 1970; Cheeke and Shull, 1985).
In contrast, in some plant species such as rhubarb (Rheum rhabarbarum), halogeton and water hyacinth (Eichhornia crassipes), oxalate content tends to increase as the plant matures.
Principles for managing ranges infested with halogeton. J.
Williams (1960) observed that control (without NaCl) treatment produced significantly lower (1.09%) soluble oxalate content in halogeton
plants than treatments of 0.001 N (3.13%), 0.01 N (3.66%) and 0.1 N NaCl (3.90%).
The PPA repealed the Plant Quarantine Act of 1912, the Federal Plant Pest Act, portions of the Department of Agriculture Organic Act, the Federal Noxious Weed Act of 1974, the Mexican Border Act of 1942, the Insect Control Act of 1937, the Halogeton
Glomeratus Act, the Golden Nematode Act, and Section 1773 of the Food Security Act of 1985.
A C-130 Hercules tactical cargo transport aircraft assigned to the Air Force Reserve's 910th Airlift Wing, Youngstown Air Reserve Station, Ohio, applies a herbicide mixture to control halogeton
, an evasive weed that can hamper bombing test evaluations and unexploded ordnance recovery, at the Utah Test and Training Range.
