DE2411900A1 - METHOD OF CONTROL OF UNWANTED PLANTS - Google Patents

Description

Our reference: OZ 30 446 Sws / Wil 6700 Ludwigshafen, 11.3-1974

The present invention relates to a method of control undesirable plants in important agricultural crops, e.g. B. Beta beets, by one or more treatments of the soil before the appearance or until the appearance of the plants and / or one or more treatments of the plants after their appearance on the soil surface.

It is known that 1-phenyl-4-amino ~ 5-chloropyridazon-6 is a has herbicidal effect. However, the effect is extreme, especially under adverse climatic conditions such as persistent Drought, against various important weeds such as AIopecurus spp., Amaranthus spp., Avena spp., Centaurea cycinus, Chenopodium spp., Echinochloa crus-galli, Euphorbia spp., Fumaria spp., Galium aparine, Mercurialis annua, Polygonum spp., Senecio vulgaris, Setaria spp., Viola spp., Anagallis arvensis, Galinsoga parviflora, Stellaria media, Raphanus raphanistrum, Sinapis arvensis, Galeopsis spp., Lamium spp., Veronica spp. and others unsatisfactory.

A method for controlling unwanted plants has been found by adding a compound of the formula:

in which R means chlorine or bromine, applied several times, the applications being carried out in the following time periods:

a. Before sowing and / or after sowing the crop plants until during emergence of the crop plants or

b. after the crop plants have been sown and 1 to 5 days thereafter until the crop plants emerge or

- 2 - OZ 30 ' ¹ TO

c. before sowing and / or after sowing the crop plants until during emergence of the crop plants and after emergence of the crop plants and unwanted plants until after the crop plants have been singulated or

d. before sowing and / or after sowing the crop plants until during emergence of the crop plants and / or after Emergence of the crop plants and unwanted plants and after the isolation of the crop plants or

e. before and after planting the crop plants before emergence of the undesired plants to after emergence of the undesired ones Plants.

This method gives a clear advantage over a single application of the active ingredient.

The advantage lies in the better herbicidal effect against resistant ones that germinate from the depths of the soil or that germinate late unwanted plants, e.g. B. Anagallis arvensis, AIopecurus myosuroides, Amaranthus spp., Avena spp., Centaurea cyanus, Chenopodium spp., Echinochloa crus-galli, Euphorbia spp., Pumaria spp., Galium aparine, Mercurialis annua, Polygonum spp., Senecio vulgaris, Stellaria media, Setaria spp., Vicia spp., Galinsoga parviflora, Viola tricolor, Raphanus raphanistrum, Sinapis arvensis, Galeopsis spp., Lamium spp., Veronica spp. and others, especially in dry climatic conditions on all soils including humus-rich soils.

Another advantage is a better selectivity when the agent is used several times, especially during emergence of crops. This makes it independent of the growth stage the cultivated plants and the undesired plants enables beet cultivation without manual labor.

The active ingredient can be used several times in different weight ratios, for. B. 5 '- 1 to I: 5 * for example 1: 1, 5: 1, 4: 1, 3' 1, 2: 1, 1: 2, 1: J>, 1: k, 1: 5, at Application rates of 0.5 to 5 and more kg of active ingredient per hectare can be used.
