Bartoline Dark creosoate Substitute 4Ltr £6.81
"New formula Creosote.
Solvent based ready to use wood preservative for amateur use against
wood rotting fungal and surface algae on external timber only.

Are these creosote subs as good as the real thing? Do they kill all
nearby plants?

Creosote substitute is just that and really has very little of the
effect of true creosote which is banned for use by amateurs and which
is in restricted use in plants for professionals

You may find that the information on Active Ingredients that follows
of some use
Propiconazole

is a systemic foliar fungicide with a broad range of activity. It is
used on grasses grown for seed, mushrooms, corn, wild rice, peanuts,
almonds, sorghum, oats, pecans, apricots, peaches, nectarines, plums
and prunes. On cereals it controls diseases caused by Erysiphe
graminis, Leptosphaeria nodorum, Pseudocerosporella herpotrichoides,
Puccinia spp., Pyrenophora teres, Rhynchosporium secalis, and Septoria
spp. (1, 2, 4).

Propiconazole's mode of action is demethylation of C-14 during
ergosterol biosynthesis, and leading to accumulation of C-14 methyl
sterols. The biosynthesis of these ergosterols is critical to the
formation of cell walls of fungi. This lack of normal sterol
production slows or stops the growth of the fungus, effectively
preventing further infection and/or invasion of host tissues.
Therefore, propiconazole is considered to be fungistatic or growth
inhibiting rather than fungicidal or killing (2).

Iodopropynyl Butylcarbamate
is used as a broad spectrum biocide or preservative to inhibit the
growth of microorganisms. End applications include metal working
fluids, polymer emulsions, and pigment dispersions, cosmetics,
household products, paints, adhesives, cements and inks. Carbamic acid
is a compound of chemical formula H2NCOOH. But it exists only in the
form of carbamate (its salt or ester), carbamide (amide) and carbamoyl
(acyl radical). Carbamates , with general formula -NH(CO)O-, have
functional groups next to the carbonyl group. Carbamate is formed when
a carbon dioxide reacts with the amino group the COO- group is a
resonance structure. Carbamate structure inhibits cholinesterase and
many insecticides and parasiticides contain carbamate fuctional group.
Carbamate is a poisonous ingredient in insecticide. Other common
examples of poisonous ingredients in insecticide include
organophosphates and dichlorobenzenes. It is highly toxic to human
also. Heavy exposure to IT can cause carbamate poisoning. Natural
carbamide (urea) can be found in protein metabolism in urine.
Carbamoyl is the radical NH2CO-, also called carbamyl. It is a radical
formed from an organic acid by removal of a hydroxyl group. It is
involved in the biosynthesis of the pyrimidine ring. Carbamoyl
compounds, such as salicylamides, are important for the preparation of
pharmaceutical products, pesticides, dyes, and biosynthesis
researches.

Permethryn is a synthetic product used as an insecticide

None of these products are anything like as effective as the ones that
the EU has removed from our arsenal of AIs

Best protection is to keep out water by design.

cheers chris. Is there anything one can add to these preparations to
improve their effectivness, eg a copper salt or cu powder?
