Copper pesticide is applied as a contact protective foliar spray, so it remains deposited on leaf surfaces. A small concentration of copper ions may be taken up by plants as essential nutrients. Copper foliar sprays are also applied to correct plant copper deficiency. [8] Excess absorbed copper ions can kill sensitive cells in copper sensitive ...
The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [1] The University of Hertfordshire maintains a database of the chemical and biological properties of these materials, [2] including their brand names and the countries and dates where and when they have been ...
Traditional fungicides are simple inorganic compounds like sulfur, [5] and copper salts. While cheap, they must be applied repeatedly and are relatively ineffective. [ 2 ] Other active ingredients in fungicides include neem oil , rosemary oil, jojoba oil , the bacterium Bacillus subtilis , and the beneficial fungus Ulocladium oudemansii .

Large scale industrial production of basic copper chloride was devoted to making either a fungicide for crop protection or an intermediate in the manufacture of other copper compounds. [6] In neither of those applications was the polymorphic nature of the compound, or the size of individual particles of particular importance, so the ...
