As a dried mixture it contains 10 to 90% by weight of lecithin, 10 to 90% by weight of dried cow's milk and 0 to 1% by weight of dried egg yolk. As an emulsion it contains 10 to 50% by weight of lecithin, 10 to 50% by weight of dried cow's milk, 10 to 30% by weight of ethyl alcohol, 0 to 1% by weight of dried egg yolk and the remaining part up to 100% by weight is water.

Description

The invention relates to a plant protection product having fungicidal effects, which is non-toxic and environmentally friendly.

BACKGROUND OF THE INVENTION

A number of fungicidal products are currently used. The vast majority of them are toxic with a negative impact on humans and the environment.

Current fungicides are on a variety of bases, organic and inorganic, and are substances harmful or toxic, often less degradable with the risk of residues in food.

Of natural substances, various extracts of herbs and seaweed are used for this purpose, which usually have a narrow spectrum of efficiency, high cost and a reduction in the source of raw materials.

SUMMARY OF THE INVENTION

The present invention relates to a plant protection product having fungicidal activity, which according to the invention contains as active ingredient lecithin and dried cow's milk (containing active substances such as albumin, casein, lactose, etc.) in a weight ratio of 1: 9 to 9: 1. The composition may be prepared in the form of an emulsion or a dried mixture from which it is prepared prior to application of the emulsion.

The dry blend composition of the invention comprises 10 to 90% by weight of lecithin, 10 to 90% by weight of cow's milk and 0 to 1% of dried egg yolk. In the form of an emulsion, the preparation contains 10 to 50% by weight of lecithin, 10 to 50% by weight of dried cow's milk, 10 to 30% by weight of ethyl alcohol (stabilizer and preservative) 0 to 1% by weight of dried egg yolk.

The preparation is preferably applied in the form of spraying on commercial and ornamental plants in the wild, in greenhouses and in households, diluted with water to a content of 2-7% by weight of active substances. The formulation of the invention can be used anytime (no withdrawal period) and anywhere, including households and near water sources. It has very good effects against fungal diseases of the powdery mildew group, for example on cucumbers, apple trees, vines, including very resistant powdery mildew and other fungal diseases such as cucumber mold; black; partial scab, etc. The preparation is harmless to useful insects and other groups of animals, is not toxic, is ecologically harmless, very quickly biodegradable and leaves residues in food or soil after use.

DETAILED DESCRIPTION OF THE INVENTION

Example 1

An emulsion of a fungicidal preparation concentrate was prepared containing 20% by weight of lecithin, 20% by weight of cow's milk, 18% by weight of ethyl alcohol, 42% by weight.

Drinking water. The concentrate was diluted with drinking water to an active ingredient content of 5% by weight. The greenhouse cucumbers, grapes, roses, gooseberries and currants were sprayed with the diluted product. After 48 hours of treatment, significant improvement was seen and the infection stopped. The preparation works for 6-10 days. With regular use, plants can be kept healthy.

Example 2

From a dry powder mixture of 50% by weight lecithin and 49% by weight dried cow's milk and 1% by weight dried egg yolk, an emulsion with 3% by weight of the active ingredients was prepared with thorough mixing. This spraying was applied to gooseberry and blackcurrant trees attacked by American powdery mildew. The first effects are seen after 48 hours, similar to Example 1. After two additional sprays between 7 and 8 days, the new additions no longer showed signs of attack, unlike the control. The preparation showed statistically demonstrable higher efficacy, 15 than the currently used conventional preparations.

Example 3

An emulsion containing 4% by weight of the active ingredients was formed from a concentrate containing 15% by weight of lecithin, 15% by weight of cow's milk, 15% by weight of ethyl alcohol and 55% by weight of drinking water. As a precaution, the spraying was carried out four times against the cucumber fungus on the outdoor stand of cucumbers and pickles. The life of the treated stand was 21 days longer than that of the untreated control.

Example 4

An emulsion of 3.5% by weight of the active ingredients mixed from a concentrate identical to that of Example 1 was applied to the growth of greenhouse roses suffering from powdery mildew. After three sprays each 7 days, the% area of the leaves infected with live mycelium was number 7. whereas on the untreated control, the leaves were 38% infected.

Industrial applicability

The preparation according to the invention can be used in agriculture, gardeners and the like to protect both useful and ornamental plants against fungal diseases.
