Abstract

A fungicidal composition with a content of tributyltin dithiocarbamate of the general formula I 14Η9 N-C-S-Sn-C-Hq 4 9 r2 S c4h9 (I) wherein R 1 is alkyl having carbon numbers 1 to 4 and R 8 is hydrogen or alkyl of carbon 1 to 4.

Description

FIELD OF THE INVENTION The present invention relates to a fungioid compound which contains, as an active ingredient, trbutylcidylthiocarbamate of the formula

NCS-Sn - c ₄ N ₉ wherein is alkyl of 1 to 4 carbon atoms and R 8 is a selector atom or alkyl of 1 to 4 carbon atoms.

In the fungicidal protection, several organotin compounds are known.

Also type R compounds.

^x - N - C - S - M, where ti is a metallic element, colt dithiocarbamates are known for a wide range of biooid effects

The present invention relates to a fungicidal composition which is characterized in that it contains, as an active ingredient, a tributyloindithiocarbamate of the general formula (I) _.

R 8 is C ₄ H ₉ wherein R 7 is alkyl of 1 to 4 carbon atoms and R 8 is hydrogen or alkyl of 1 to 4 carbon atoms.

These substances achieve the same or higher fungicidal activity, while the newly synthesized substances, which are the basic constituents of the composition, have saler advantageous properties, do not smell and do not volatilize at normal temperatures from protected objects, do not decompose under light they can be well applied to porous materials such as lignocellulosic materials. They may have found better application especially in fingioid protective wood, furniture, historical monuments of wood, but also as an antifungal additive in plasters, paints and varnishes and in other places where the lastanox commercial product is used.

The fungicidal efficacy of the newly synthesized organotin species is demonstrated in some examples without. and these were exclusively applicable.

Example 1

The poisoned agar platform was obtained by mixing 13.5 ml of 3% malt agar and 1.5 ml of a 0.1% organotin solution. 0.01, respectively. 0.001%. Corsped Corolius versicolore and Conlphora puteana were inoculated onto the prepared agar. An inoculum of 0.5 x 0.5 mm was obtained with a scalpel. Myelium growth was performed at 25 + 2 ° -O and BV = 96% for 3 days. The mycelial growth was then measured and the blocidic effect was evaluated according to the formula:

Known fungicides were evaluated in the same manner.
