Embodiment 1

[0099] Production and measurement methods of defined matrices

[0100] A. Producing at least 20 kg of substrate with the exact proportions of humic substances:

[0101] ·Sand 0-4mm washed, Coop DIY supermarket, 25kg quantity, 3 packs

[0102] · Granules, Humintech GmbH, 25kg, 1 pack

[0103] Granules, based on soft lignite, with a high proportion of weathered lignite, confirmed humic acid complex content of 60%.

[0104] This material represents a very good basis for producing a substrate with the desired concentration of humic substances.

[0105] 1 Concentration 0.5%

[0106]

[0107] 2 Concentration 2%

[0108]

[0109] 3 Concentration 16%

[0110]

[0111] B: Determination of humus, bacteria, fungi, micro-animals

[0112] These assays were obtained substantially according to established methods, in particular as described in "Bodenbiologische Arbeitsmethoden", 2nd revised and expanded edition (second revised and expanded edition), F. Schinner, E. Kan...

Abstract

The invention relates to a method for protecting plants from pests, in particular bacteria, fungi, and viruses, using a pesticide composition with adjustable persistence and degradability, having thefollowing steps: providing a pesticide composition which comprises at least one poly(alkyl)guanidine with a monomer alkyl chain length ranging from C2 to C20 and a degree of polymerization n ranging from 2 to 600, and applying the pesticide composition to plant cultures for a specified time and in sufficient quantities in order to prevent or inhibit an adversive effect of the pests on the plants,wherein the length of the monomer alkyl chain and / or the degree of polymerization are set depending on at least one characterizing parameter of the soil or nutrient medium in which the plants are cultivated such that a specified or desired persistence and degradability of the pesticide composition on the cultures or in the soil or nutrient medium are obtained. In a special embodiment of the methodaccording to the invention, the at least one characterizing parameter of the soil or nutrient medium is determined in a first step, and the parameter is preferably selected from the pH value, the humus content, the humin content, the content of microorganisms, the content of soil fungi, or the content of soil bacteria.

Description

Background technique [0001] Traditionally, a wide range of chemical compounds have been used to protect plants, especially cultivated plants, from various pathogens. [0002] These compounds should on the one hand exhibit the highest possible efficacy against one or more plant pests and on the other hand have the lowest possible toxicity to humans and animals. In many cases, it is difficult to coordinate these requirements. Furthermore, especially in the past few years, due to growing environmental concerns, the allowable limits of pesticide residues in soil have been lowered globally, and further restrictions may be expected. [0003] Conventional insecticides are having difficulty coping with this trend. Farmers will be forced to drastically reduce application rates and / or frequency, thereby accepting reduced efficacy and increased risk of resistance or to move to more degradable plant protection products. However, the latter are not equally effective against all pathogen...
