The resulting extracts were applied to soil flats containing watergrass (Echinochloa crus-galli) as an indicator species at the very high application rate of 100 pounds per acre (112 kg/ha). There was a herbicidal effect from this test, so the extracts were developed on a preparative thin layer chromatographic sheet.
Tribenuron has a broad spectrum of activity on commercially important broadleaf weeds and grasses but at the recommended use rate it is safe to important crops such as wheat. When introduced by DuPont, its recommended application rate was 0.015–0.03 pounds per acre (17–34 g/ha). [9]
Triclopyr is a selective weedkiller used to control dicotyledonous weeds (i.e. broadleaf plants) while leaving monocotyledonous plants (mostly bulbs, grasses and conifers) unaffected, [2] or to control rust fungus on soybean crops.
In the same report, it added the "yield loss plus increased herbicide cost may result in an average estimated loss of $28 per acre" if atrazine were unavailable to corn farmers. [4] In 2006, the EPA concluded that the triazine herbicides posed "no harm that would result to the general U.S. population, infants, children or other... consumers." [5]
The product is used at application rates of 0.008–0.0155 pounds per acre (9.0–17.4 g/ha). [16] The estimated use in US agriculture is mapped by the US Geological Service and shows that from 1992 to 2017, the latest date for which figures are available, up to 120,000 pounds (54,000 kg) were applied each year.
In the United States as of 2014, atrazine was the second-most widely used herbicide after glyphosate, [16] with 76 million pounds (34 thousand metric tons) of it applied each year, [19] [20] nearly identical to its usage in 1974, of 76.8 million pounds. [21] Atrazine continues to be one of the most widely used herbicides in Australian ...
Local Bounti already has started expanding the 3-acre greenhouse to double its size with the potential to grow the greenhouse up to 24 acres of the 30.38 acre site, according to the release.
Alachlor is an herbicide from the chloroacetanilide family. It is an odorless, white solid. The greatest use of alachlor is for control of annual grasses and broadleaf weeds in crops. Use of alachlor is illegal in the European Union [1] and no products containing alachlor are currently registered in the United States. [2]
