Description

Plant protection product with fungicidal effects

Technical field

The invention relates to a plant protection product having fungicidal activity, in particular against mildew, which is non-toxic and environmentally friendly.

BACKGROUND OF THE INVENTION

Hundreds of fungicidal products are currently used. Most of them are synthetic more or less toxic substances with a more or less negative impact on humans and the environment. For example, metal compounds such as copper and zinc, sulfur, and complex organic compounds dinocap, thiophanate-methyl, ilusiazole and many others.

SUMMARY OF THE INVENTION.

The present invention relates to a plant protection product having fungicidal activity, in particular against Erysiphales, which according to the invention contains from 5 to 70% by weight of active ingredient. % of vegetable oil or a mixture of vegetable oils (e.g. rapeseed, sunflower, soybean, corn, coconut, olive oil, etc.), and 0.5 to 20 wt. . vegetable lecithin (soybean, rapeseed, sunflower, etc.), the remainder up to 100 wt. is water. It may furthermore preferably contain from 0.001 to 0.1 surfactants, based on the amount of active ingredients. The composition may also contain up to 20% by weight, preferably 5 to 17% by weight.

ethyl alcohol, which acts as a stabilizer and preservative. The composition is preferably applied in the form of 0.1 to 5%

umulze. As the wetting agent, VELVETU 2000 with the active ingredient alkyl polysaccharide, Citowett or a sticky soap and dishwashing agents such as JAR can be used.

The composition of the invention is not toxic to humans, warm-blooded animals, most useful insects and soil organisms. It breaks down quickly into harmless components in the ground.

It is used on plants so that the plant is spray-wetted. Powdery mildew has preventive and curative effects, other fungal diseases, such as some fungi, especially preventive. It is used, for example, against fungal diseases of powdery mildew, cucumber, apple, vine, including the very resistant American mildew, and also against cucumber, black, partially scab, and others.

The advantage of the preparation is its non-toxicity. for the abovementioned groups of organisms, rapid degradability, possibility to use the product at any time, for example during the ripening period (the product has zero withdrawal period).

DETAILED DESCRIPTION OF THE INVENTION

EXAMPLE 1 A 0.5% emulsion of a preparation of 55% pot was prepared. rapeseed oil, 2 wt. % soya lecithin, 43 wt. water by dispersion in water and 0.05 wt. VELVET 2000 wetting agents based on the amount of active ingredients Greenhouse cucumber plants infected with cucumber powdery mildew were sprayed until the beginning of the harvest. After 7 days the spraying was repeated. The percentage of infections in the treated plants was 3%, in the control 32%.

Example 2

A 1% emulsion of the formulation was prepared from a mixture of 30 wt. sunflower oil, 5 wt. rape lecithin, 53 wt. water, 12 wt. % ethanol by dispersion in water and added 0.1 wt.%, based on the amount of active ingredients, of the dishwashing detergent JAR. This mixture was sprayed with garden roses in the initial state of infestation with powdery mildew until they were felled. Spraying was repeated twice after 7 days. The percentage of infections in the treated plants was 2%, in the control 40%.

Example 3

A 2.5% emulsion of the formulation was prepared from a 20 wt. % soybean oil, 15 wt. sunflower lecithin, 15 wt. % of Iaikohoiu and up to 100 wt. water. 0.08 wt. (based on the amount of active ingredients) of Cittowet. This emulsion sprayed tree gooseberries of the Golden Fig variety at the beginning of the attack by American powdery mildew. Every 7 days, this spray was repeated 3 times. The percentage of shoot infestations was 5% and the fetuses 2% in the treated plants. For control, 46% for shoots and 28% for fetuses.

Example'4

A 0.3 wt.% Emulsion of the formulation was prepared from a 40 wt. corn oil, 15% rapeseed oil and 7% wt. sunflower lecithin, supplemented to 100 wt. water. Greenhouse tomatoes were sprayed with this emulsion 3 times after 5 days. The percentage of infected leaves was on average 3.7% for treated variants and 19% for controls 20 days after the first treatment.

Industrial applicability

The preparation according to the invention can be used in agricultural practice and in households to protect cultivated plants against fungal diseases, in particular from the group of fallen. The greatest use can be expected in gardeners. and alternatively farming farmers. The product can be successfully applied to both commercial and ornamental plants in the wild, greenhouses and households.
