Zwykle substancje czynna o ogólnym wzorze 1 sitosuje sie w dawkach 0,25—1,0 k^/ha, a substancje czynna o ogólnym wzorze 2 w dawkach 0,1—0,4 kg/ha.Szczególnie korzystne jest stosowanie srodka we¬ dlug wynalazku w uprawach zbóz i kukurydzy, przy czym sobstancje czynna o wzorze 1 podaje sie w dawce 0,5—1,0 kg/ha, a substancje czynna o wzo¬ rze 2 w dawce 0,2—0,4 kg/ha.Aby stwierdzic, czy rnieszanana daje w rezulta¬ cie dzriialamiia sumaryczne czy synerglLczne wychodzi sie zazwyczaj z nastepujacego równania: E=X+Y- XY 65 aoo (wedlug DimpaTa, L.

The agents according to the invention are used in the treatment of visage plants* The dosages of the active substance mixture can also vary within a certain range. They depend on the composition of the mixture of these active substances and on the type of weed infestation. Typically, the active substance of the general formula 1 is applied in doses of 0.25-1.0 kg/ha, and the active substance of the general formula 2 in doses of 0.1-0.4 kg/ha. It is particularly advantageous to use the agent. the invention in cereal and corn crops, where the active substance of formula 1 is administered at a dose of 0.5-1.0 kg/ha, and the active substance of formula 2 at a dose of 0.2-0.4 kg/ha To determine whether a change results in cumulative or synergistic effects, the following equation is usually used: E=X+Y- alone and in centaiin combaoation^ Proc.NEWOC 16:48^53, based on Gowiing, D.P. 1960, Comments on theists otf hembicide mixitiuires, ^eeds 8:379^391), in which they mean: E = degree of herbicidal activity (° (o weed destruction) after application of substance A+B at a dose of p+q kgi/lia,5 X = degree of action (%) when using substance A at a dose of p kg/ha, Y = degree of action (%) ^ when using substance B at a dose of q kg/ha. If the value calculated according to the above equation is higher, syneangizan occurs, and if the experimental value is lower, antagonism occurs. The results in tables 1-5 clearly show that in almost all cases of mixtures of active substances I + II or I + 111, the degree of herbicidal activity (% zindszczemia) is significantly higher than the expected (calculated) values for the pure total plant. The practical benefit of syneirgizim in the scope shown here is extremely high. As you know, the ratings of E.W.R.C. for the rate of herbicidal activity, it is assumed that there is an exponential relationship between the degree of activity (% destruction) and the number of ratings (and the resulting rating) in such a way that in the practical range of 85-^100P/* the destruction is much more , different than in the economically important range of 0-85% destruction (compare the E.W.R.C. rating scales). •» -i ¦)¦ The increase in the degree of action in this upper range is therefore more important than in the lower range. Improving the degree of performance from e.g. 05% to 100% (+5%) equals an improvement of two degrees (rating scale notes), while increasing the degree of performance e.g. from 70% to 80% {+ 110%) corresponds to only one note on the grading scale and has little practical significance (both 70% and 80% destruction are not considered sufficient). As the example given below shows, especially in the range of 85-100% destruction weeds, in all cases a symergetic increase in effect of an economically significant extent is observed. The example also proves that already at doses of 0.25 kg/ha of compound I (Pyridate) and 0.1 kg/ha of compound II ( Ioxynii-octianoiate) the degree of herbicidal activity against all certified weeds is much higher than the total effect of the individual ingredients. The synergistic effect is particularly noticeable in this case, e.g. for the weeds Galeopsds tetoiahit, Lamiuim purpuireuim (purple grass) and Varonica hederitfolia (leafweed) it is +26%, +27% and +29%. In the case of a mixture of 0.26 kg/ha of compound I with 0.2 kg/ha of compound II, of great practical importance is the increase in the degree of herbicidal effect on the Galiiuim aparime (catch's bedstraw) which is difficult to kill, up to 98% destruction, which corresponds to very good knitting according to the E.W.R.C. grading scale. In the case of mixing 0.5 kg/ha of compound I and 0.2 kg/ha of compound II, with the exception of Polygomium convulivuILus (convolvulus knotweed), 100% of all weeds, especially Galojum apairaine, Z 688 6 Compound III (Bromoxynii-ocrtanoate) is very similar to compound II (Ioxynii-octanoaite) in its chemical, lytic and biocidal properties. Accordingly, the nergic effect also occurs in a completely similar way, which is visible from tables 4 and 5. Example. Rectangular plastic boxes (35X138X7 cm) served as experimental units, in which the given - Jan. The following field weeds of common economic importance were used in the tests: Chenppodifum album Gialeopsis tetraihit GaMaum aparine Lamium purpureum Lapsana romimuinis Lithosperrnuni ar- vense Maltiricairia chaimo- milla Papaver rhoeas Polygonum convul- vulus SteWLaria media Veironica ihodealifelia koimosa white lny = clinging bedstraw = poirpuir's milkweed = common lilac = field headland = common chamomile = ;field poppy = morning knotweed = common starwort = speedwell = A B C D E F G H I K povischodowynia (Galiuni 'aparine, e.g. branched with 3-6 spindles and side shoot, Lapsana omimunis at stages 6-8 leaves, Maitricaria ohanaomilia at stage 8-10 (leaves, SteHlairia media already branched, with 4-6 leaves) leaves in a side shoot, Galeopsis tetirahit with 2-3 pairs of leaves developed, etc.), were sprayed with active substances or mixtures of active substances and in the given doses. The amount of spray broth was 500 liters/ha. After 4 weeks of spraying, 45 degrees of herbicidal activity were determined. The residual weed infestation - separated by weed species - was harvested and the weight of freshly cut weeds was determined. Weeds from the remaining 50 untreated comparison boxes were treated in the same way. Residual weed control was compared with weed control in untreated weed plots and the degree of weed killer (% weed destruction) was determined in this way. These values, in the case of mixtures of active substances, were examined using the Lampel equation in order to determine the possible synergistic effect.
