What is propazine used for?
Application Sites: Propazine is a selective herbicide that can be applied before planting, at planting and after crop emergence for preemergence control of annual broadleaf weeds in container grown ornamentals grown in greenhouses. Application Types and Methods: Spray tank using flood or drench nozzles only.
Why is atrazine banned?
“Atrazine is toxic to coral reefs and endangered species. Research has linked atrazine to birth defects and cancer in people, and even miniscule doses can chemically castrate frogs. It has been banned or is being phased out in more than 35 countries but is the second-most commonly used herbicide in the United States.
Where do you find atrazine?
Atrazine has been found in water collected from many drinking water wells in the Midwestern United States. Therefore, you may be able to reduce your risk of exposure to atrazine by ensuring that your water supply is free of atrazine, or contains no measurable levels of atrazine.
Is atrazine still being used?
How do I apply atrazine?
Mix 4.33 ounces of Atrazine per gallon of water. When mixing in a container, pour Atrazine first, followed by water for best results. Apply the mixture to 500 square feet of lawn. Do not increase Atrazine content per gallon of water.
When Should I spray my yard with atrazine?
You should apply Atrazine when the ground is dry. This product will control both emerged weeds and weeds from seeds. Rain or water within 2 or 3 days of application may decrease the effectiveness on emerged weeds.
Is atrazine safe to use?
Atrazine has a stellar safety record. In 2006, the EPA completed a 12-year review that included 6,000 studies and 80,000 public comments. When agreeing to re-register the product, EPA concluded that it provided no harm to people. Moreover, the World Health Organization has found no health concerns with atrazine.
How does propazine work as a weed killer?
Propazine is a systemic herbicide that is usually applied to the soil, absorbed through leaves and roots, and acts by inhibiting photosynthesis within the targeted plant. It is used as a selective herbicide to control most annual grasses and broadleaf weeds before the weeds emerge or after removal of weed growth.
When was propazine classified as a possible carcinogen?
Propazine was originally classified in 1989 as a Group C carcinogen, or possible human carcinogen, and was considered to have a non-threshold mechanism for tumor formation. In other words, a threshold, or dose below which the risk of developing cancer is negligible, had not been identified for propazine.
What’s the difference between Chloro and propazine?
Propazine is a diamino-1,3,5-triazine that is N,N’-di(propan-2-yl)-1,3,5-triazine-2,4-diamine substituted by a chloro group at position 6. It has a role as a herbicide, an environmental contaminant and a xenobiotic. It is a chloro-1,3,5-triazine and a diamino-1,3,5-triazine.
What is the half life of propazine in soil?
AEROBIC: In soil, microbial degradation of propazine occurs, with hydrolysis of the chlorine atom to give hydroxypropazine, dealkylation of both substituted amino groups, presumably followed by ring opening and decomposition(1). The half-life in soil is approximately 80-100 days(1).
