to the monocot weed seedlings.

In the event of a sufficient amount of precipitation, N '- (3t ^ -sichlorophenyl) -F, N-dimethylurea destroys part of the deep-rooted dicotyledons, as well as some types of grass. The cicotyledonous weeds are selectively eradicated by the lf ^t - (3 | 4-Diclilorphenyl) -N-methox-f - ^ - ^ iiethylhernstcff, and an effect on some more sensitive monocots is also exerted.

Long lying seeds in the ground - up to now by hand, with a spade and hoe from the alfalfa, glue clover and horn clover would have to be exterminated, which is due to the great similarity of the foliage of the hatching plant and the weeds appearing only at the time of flowering, in the summer Work period _t could be executed with a sure success.

By using the active ingredient combination according to the invention, this laborious and costly selection is replaced with manual labor, with cheap and safe one Herbal treatment made possible, the effect of which extends over the entire vegetation period.

According to our experimental experience, by combining the three compounds, the discussed selective and synergetic effect is developed "on a significant scale" when the active ingredient content is 30-30%, two-way 60 % rat triochloroacetate, 10-25% "expediently 20 % H ¹ - (3 »4-diochlorophenyl) -! R, F-dimethylurea and 10-25 %, expediently 20 % H ^f - (3,4-diochlorophenyl) -H-methoate-H-methylurea. The amount of herbicide used per hectare, based on the combination of active ingredients, is two cubic meters & Big 12-20 kg, in the form of 400-1000 liters of aqueous spray.

The long duration of action of the with the invention Combination of active ingredients produced herbicidal means enables the perennial Sehmetterlingsblütler-AnpflanzungeL to be sprayed. in the vegetation break, in the period from late autumn to spring, which, according to our experience, causes the Combating the undesired foreign species of clover between the podaceae useful plants used for growing seeds is practical completely succeeds. With spring spraying, the effectiveness of weed control with regard to the clover species mentioned was found to be 60 percent on average.

The active ingredient combination according to the invention can be used in usual formulations of herbicidal preparations on the market

Experimentally we have found that swisohen den different formulations - based on the same active ingredient content - neither in terms of selectivity nor in terms of the synergetic effect - there is a significant l & itersohied.
