Übersetzung für "Schaderreger" in Englisch

The compounds according to the invention are particularly suitable for controlling the following pathogens:

Modern active substances in plant protection products are characterised by their targeted effect on specific harmful organisms.

Similar strategies are being pursued for pests in viticulture.

These were the pests and diseases which can occur at Helleborus under bad conditions.

The compounds according to the invention are particularly suitable for controlling the following pathogens:

The microbial antagonists are moreover chosen with respect to their efficiency as to soil-borne harmful organisms.

Hypoaspis can reduce the pest when applied regularly and as a prophylactic to slow down the population growth.

Harmful organisms repeatedly break through any resistance.

The system then modifies process parameters depending on the harmful organisms detected in the water.

In scientific field trials, action thresholds for selected pests are re-assessed, adjusted and declared valid and binding.

For plants, it means the occurrence and spread of increased harmful organisms from southern regions.

It is desirable to establish plant health and quality standards for each genus and species of fruit plant based on international schemes which may include, inter alia, provisions for pathogen testing.

Literature of this field mentions chemical methods of fighting, which are directed against fungal and bacterial damaging inciters on the potato tubers.

Surprisingly, it was found that mixtures of antimicrobial compounds of the general formula I with a variety of fungicides, particularly with benzimidazole fungicides, allow excellent control of fungal and bacterial inciters alone or in mixed infections and furthermore show an increased effectiveness far above the effect of the single compounds.

In order to successfully combat all injurious inciters, it was found advantageous to use a mixture comprising a benzimidazole fungicide and chloramphenicol (DD-WP Nos. 110,423 and 130,427).

Electron energy and radiation dose are chosen such that microbial harmful organisms are killed without any produce-affecting or phytotoxic effects on the germ of the seed corns.

In particular, prior to their use the grain seeds are subjected to a dressing procedure by which the spreading of such harmful organisms is to be prevented or restricted.

The use of high energy rays (? rays, X-rays) to combat microbial harmful organisms is not possible on seeds because the necessary radiation dose for achieving a fungicidal effect on the seeds is phytotoxic or mutagenic.

Both with regard to the treatment of seeds with active fungicidal substances or agents and the treatment with antagonistic microorganisms and/or their nutrient broths, culture filtrates and antibiotic metabolic products following an irradiation of the seeds with low energy electrons, a surprising synergistic and increased effect was observed with respect to seed- and/or soil-borne harmful organisms without any produce-affecting phytotoxic effects.

Of course, the application which consists of active fungicidal substances or agents or of microbial antagonists and of the above-explained other microbial application forms (or a mixture of fungicides and biological components to combat harmful organisms) can also be made to act on the seeds by immersing the seeds thereinto.

In cases where the sole irradiation of seeds with low energy electrons (to avoid phytotoxic effects) for fighting harmful organisms that penetrate into the embryo of the seed, such as smut and partly also Fusaria, is not successful enough because of a depth action which is too small, great successes can surprisingly enough be achieved through the combined use of electron dressing with an immediately following treatment with active fungicidal substances in accordance with the invention.
