Description

The present invention provides a stable fungicidal formulation in the form of a dispersible powder, based on N-trifluoromethyl-1,2,2-trichloroethyl / morpholine alone or in admixture with other pesticides. .

N71-O, 100-2,2,2-trichloroethyl / moofdine is an antifungal fungicide (art. No. 193 6591), which is formulated into an emulsion granulate concentrate and a dispersible powder for application purposes.

The pesticide formulation to fmry dLspergo5 ^ e ^ e ^ ^aí, Joint powder using the well known non-ionic and ionic povrchovoaktévnl agents, protective colloids, and inorganic fillers.

It has been shown that the N- (1-formamino) -2,2,2-trichloroethyl / morphdine-modified powder treated with known drugs is unstable during long-term storage. The sewage analyzes increase the gross share of the sieve »Such a preparation is practically unusable after a few weeks of storage with agricultural practice ·

A new stable fungicidal formulation has now been found in the form of a disulfurated powder, based on N- (1-Cyclomethyl-2,2,2-marketolylthyl) fluorine alone or in admixture with other pesticide-containing occlusive active agents, inert foaming agent and a protective whoid. The essence of the invention consists in:. it further comprises orípгtack anhydride RTA acid methyl ester and anhdrid maeinovej and the following turn ^ sentation of components: 2-80% hmoonootných N / _l-l-2 foгmmino 2,2-trihUlórltyl / mocfoli'nu or its. mixed with other pesticides, up to -15% by weight of the glycol or electrolytic occlusal substances, up to 15% by weight of the protective amide,

From 0.5 to 10% by weight of flicic anhydride and maine anhydride, the remainder to 100% by weight of an inert foamer.

As pesticide active substances, kdoidium sulfur, mmnkozeb (zinc lime ethylene glycol micaeate), Cu-ooychhooid, phosmet 10, O-dimetlt-S-phthaimia can be used! dcetltdiitofocfát // ·
