DBNPA or 2,2-dibromo-3-nitrilopropionamide is a quick-kill biocide that easily hydrolyzes under both acidic and alkaline conditions. It is preferred for its instability in water as it quickly kills and then quickly degrades to form a number of products, depending on the conditions, including ammonia, bromide ions, dibromoacetonitrile, and dibromoacetic acid.

The Biocidal Products Directive (BPD) also known as the Biocides Directive is European Union Directive, (98/8/EC), which concerns biocides. It is officially known as Directive 98/8/EC of the European Parliament and of the Council of 16 February 1998 concerning the placing of biocidal products on the market . [ 1 ]
Bronopol is used in consumer products as an effective preservative agent, as well as a wide variety of industrial applications (almost any industrial water system is a potential environment for bacterial growth, leading to slime and corrosion problems - in many of these systems bronopol can be a highly effective treatment).
The biological activity of a pesticide, be it chemical or biological in nature, is determined by its active ingredient (AI - also called the active substance). Pesticide products very rarely consist of the pure active ingredient.
A biopesticide is a biological substance or organism that damages, kills, or repels organisms seens as pests.Biological pest management intervention involves predatory, parasitic, or chemical relationships.
Agricultural spray adjuvants are part of integrated pest management, and during pesticide application are used to enhance the effectiveness of pesticides, herbicides, insecticides, fungicides and other agents that control or eliminate unwanted pests.
THPC can be synthesized with high yield by treating phosphine with formaldehyde in the presence of hydrochloric acid. [1]PH 3 + 4 H 2 C=O + HCl → [P(CH 2 OH) 4]Cl. The cation P(CH 2 OH) 4 + features four-coordinate phosphorus, as is typical for phosphonium salts.
Algaecide or algicide is a biocide used for killing and preventing the growth of algae, often defined in a loose sense that, beyond the biological definition, also includes cyanobacteria ("blue-green algae"). [1]
