Plant fungicide

Copper(I) carbonate (Cu + CO Cu Oj) is known as cuprous carbonate since coppers ion is +1 copper(II) carbonate (Cu + CO — CuCO ) is known as cupric carbonate, which is also known as the green copper mineral malachite, used in pigments, as an insecticide, as a cosmetic astringent, and as a plant fungicide to prevent smut. 

Use Dyeing textiles, either directly or with mordant plant fungicide, staining bacteria, antiseptic. 

Use Plant fungicide, starting material for derivatives that are also pesticides. 

CAS 17406-45-0. C H NO. A glycosidal alkaloid prepared from the dried leaves and stems of the tomato plant. White crystals used as plant fungicide and as a specific precipitating agent for cholesterol and other sterols. The crude extract is referred to as tomatin. 

USE Plant fungicide, more phytotoxic than Bordeaux mixture. 

White odorless crystals, mp 117-119 Practically in sol in water (13.7 ppm at pH 7). Sol in most organic solvents Vapor pressure at 25 < 10 7 millibar. LDM in mice, rats (mg/kg) 4500, 2500 orally (Beraud). use Plant fungicide. 

Bonide Sulfur Plant Fungicide A259 Precursor 133... 

Sulphur has various allotropic forms. Below 95.6°C the stable crystd form is rhombic above this temperature the element transforms into a triclinic form. These crystalline forms both contain cyclic Sb molecules. At temperatures just above its melting point, molten sulphur is a yellow liquid containing Ss rings (as in the soiid form). At about 160°C, the sulphur atoms form chains and the iiquid becomes more viscous and dark brown. If the molten sulphur is cooled quickly from this temperature (e.g. by pouring into cold water) a reddish-brown solid known as plastic sulphur is obtained. Above 200°C the viscosity decreases. Sulphur vapour contains a mixture of S2, S4, Sg, and Ss molecules. Flowers of sulphur is a yellow powder obtained by subliming the vapour. It is used as a plant fungicide. The element is also used to produce sulphuric acid and other sulphur compounds.
