What is 2,4-D herbicide?
2,4-D is a widely used herbicide that controls broadleaf weeds that has been used as a pesticide since the 1940s. It is used in many places including turf, lawns, rights-of-way, aquatic sites, forestry sites, and a variety of field, fruit and vegetable crops. It may also be used to regulate the growth of citrus plants.

What is the structure of mecoprop?
Mecoprop appears as colorless crystals. Corrosive to metals. Used as an herbicide. 2- (4-chloro-2-methylphenoxy)propanoic acid is a monocarboxylic acid that is lactic acid in which the hydroxyl hydrogen is replaced by a 4-chloro-2-methylphenyl group. It is an aromatic ether, a monocarboxylic acid and a member of monochlorobenzenes.
What is the pKa of mecoprop?
pKa = 3.21 pKa = 3.1 Mecoprop has an asymmetric carbon & therefore exists in 2 enantiomorphs, of which the commercial product contains equal amounts; forms water -sol salts with many inorganic & organic bases; esters of the lower alcohols are solids or volatile liquids
Is mecoprop toxic to metamorphosis?
Mecoprop in particular injured shell formation with an increase of shell abnormalities following herbicide concentrations. The active substances were not toxic to metamorphosis processes, but 2-MCP was revealed to be more toxic to the success of metamorphosis (EC50: 7.20 mg/L) than to embryo-larval development.
What is the half life of mecoprop?
Mecoprop is stable to aqueous hydrolysis at pH 5, 7 and 9 (2). Mecoprop absorbs UV light at wavelengths between 280 and 290 nm (3). Mecoprop, in river water (pH 7.31), exposed to sunlight had a half-life of 19.5 days, in the dark the half-life was 37.7 days (4).
