They are indeed dusting agents for waterless application Use, but these have the big disadvantage that they do not wind and rain resistant bind. This serious defect could so far have not been remedied by the use of auxiliary substances, nor by the variety of suitable carrier substances, so that with the previously used dusts that which can be achieved with sprays permanent protective effect could not be achieved even by multiplying the quantities used

The objective was to develop a powdery one Plant protection product, which is based on the Humidity and / or the humidity at ocer under the Plant surface permanently adheres to the plant surface. This goal could be achieved through the simultaneous use of solid additives that are even subject to little exposure Tie wet well, and appropriately prepared adhesive can be achieved. Dusts produced in this way still adhere Apply eo strongly to the plant surface so that it is not washed off by rain and even by vigorous mechanical Effects, e.g. by brushing, can hardly be removed.

Among those which bind well to the action of little water The hydraulic binders, especially portland cement and plaster of paris, proved to be suitable for pests This substance is combined with the lanzensktmtz- «irketoff, a Adhesive which, if necessary, was previously treated with a

iAD ORIGINAL

Dae good adhesion dee erfindungsgemiisBen Stüubemittels to V ^r einrebenbltitter is beetülißt of field trials by those indicated in Tables 1 and 2 data. As can be seen, the adhesiveness in rain-free periods (Table 1) reaches the adhesiveness of the flan protection agents used in the form of fuel, in contrast to the conventional substances, which almost do not adhere and trickle off in a few days. In periods of maintenance (Table 2), the adhesion of the ingredients according to the invention is understandably significantly better than the adhesion of the usual fuel agents.
