Dazomet is synthesized from carbon disulfide (CS 2) and diluted methylamine (CH 3 NH 2). After stirring for 1-2 hours, an oily substance is formed, which is the intermediate methyldithiocarbamic acid (HS 2 CNHCH 3). Then, formaldehyde (CH 2 O) is added to the intermediate to form and precipitate out the dazomet. [6]
Bentazon is a selective herbicide as it only damages plants unable to metabolize the chemical. [1] It is considered safe for use on alfalfa, beans (with the exception of garbanzo beans [1]), maize, peanuts, peas (with the exception of blackeyed peas [1]), pepper, peppermint, rice, sorghum, soybeans and spearmint; as well as lawns and turf.

Peppermint (Mentha × piperita) is a hybrid species of mint, a cross between watermint and spearmint. [1] Indigenous to Europe and the Middle East, [2] the plant is now widely spread and cultivated in many regions of the world. [3] It is occasionally found in the wild with its parent species. [3] [4]
Peppermint extract is commonly used in cooking, as a dietary supplement, as an herbal or alternative medicine, as a pest repellent, and a flavor or fragrance agent for cleaning products, cosmetics, mouthwash, chewing gum, and candies. [1] [2] Its active ingredient menthol causes a cold sensation when peppermint extract is consumed or used ...

The pesticide manual provides much information on pesticides. [6] [7] Many of the insecticides in the list are not in use. The developer of a pesticide applies for a common name when they intend to sell it, but some nevertheless do not reach the market. Many insecticides have been banned or otherwise withdrawn from the market over the decades.
Pesticide standard values for many current and historical largely used pesticides such as DDT, aldrin, lindane, glyphosate, MCPA, chlorpyrifos, and 2,4-D often vary over seven, eight, or nine orders of magnitude and are log-normally distributed, which indicates that there is little agreement on the regulation of pesticide standard values among ...
SPEARpesticides (Species At Risk) is a trait based biological indicator system for streams which quantitatively links pesticide contamination to the composition of macroinvertebrate communities. [1] The approach uses species traits that characterize the ecological requirements posed by pesticide contamination in running waters.
