Herbicide preparation, which contains a mixture of two active substances.

The invention relates to a herbicidal composition, which together contains 10-80% by weight of a compound of formula 1 of the formula sheet and a compound of formula 2 of the formula sheet, further comprising 14-80% by weight of at least 5 4 A liquid hydrocarbon with a boiling point of 150-320 ° C, as well as 6-15% by weight of an additive or additives, commonly used in the preparation of agricultural chemical preparations. In formula 2, R 1 represents an ethyl, η-propyl, iso-butyl or cyclohexyl group; R2 is an ethyl, η-propyl, n-10 butyl or isobutyl group; or and R2 together form a hexamethylene group; furthermore, it is an ethyl or n-propyl group, provided that R 1 and R 2 may not simultaneously represent n-propyl when R 1 is ethyl.

The N, N-dialkylthiocarbamic acid-S-alkyl esters have been known in the literature for nearly twenty years (see, e.g., U.S. Pat. Nos. 2,913,327, 3,087,853, 3,175,897, 3,185,720, 3,198,786, and 3,582,314 ). The herbicides commonly referred to as thiocarbamates have been used especially successfully for protection against monocotyledone weeds.

The derivatives developed so far, ie the N, N-diisobutylthiocarbamic acid-S-ethyl ester (Butylate), N, N-di-n-propylthiocarbamic acid-S-ethyl ester (EPTC), N, N-di-n-propylthiocarbamic acid- Sn-propyl ester (Perbulate), N-ethyl-Nn-butylthiocarbamic acid-Sn-propyl ester (Vernolate), 25 N-ethyl-N-cyclohexylthiocarbamic acid-S-ethyl ester (Cycloate) and N, N-hexamethyleenthiocarbamic acid-S-ethyl ester (Colinate) , can be used for various crops; they exhibit different selectivity to the crops and the weeds, while their physicochemical properties which affect their action are considerably different (water solubility, vapor pressure, etc.).

For example, the solubility of Butylate in water is only 12% of that of EPTC (at 20 ° C 45 mg / 1 as opposed to 370 mg / 1), while its vapor pressure is practically half of the latter (at 25 ° C 1.73 Pa as opposed to 8202720 ί ϊ Λ - 2 - up to 4.53 Pa).

The use of the Ν, Ν -disubstituted thio-carbamic acid-S-alkyl esters for the protection of plants is mainly dependent on the weather conditions (temperature and rainfall), because of their different physico-chemical properties, so that their use is limited . Their disadvantage is that they control dicotyledone weed species to a lesser extent and when used in an amount required for effective weed control, from time to time they have a phytotoxic effect on the crops to be protected, exercise. In order to improve the control activity against dicotyledone weeds, it has been proposed to combine the thiocarbamic acid derivative with s-triazine derivatives, while to reduce their phytotoxic activity they have been combined with compounds with a so-called antidotal effect (see eg Hungarian U.S. Patent No. 165,736).

In the course of the research carried out by the applicant, aimed at investigating the herbicidal activity of thiocarbamic acid S-esters, it has been found that all these disadvantages can be considerably reduced or eliminated, respectively, if one uses a combination of the two derivatives in a given ratio, so that one derivative is always the N, N-di-n-propylthio-25 carbamic acid S-ethyl ester (EPTC) of formula 1, while the other is one of the derivatives of a thiocarbamic acid of formula 2, ie Butylate, Perbulate, Vernolate,

Cycloate or Molinate.

Experiments have shown that a herbicidal composition containing a mixture of the two aforementioned derivatives can be used not only depending on the weather, but that such preparation also exhibits synergism in certain proportions with respect to the weed species.

On the basis of these results, the invention relates to a herbicide preparation containing a mixture of two active ingredients. In this preparation, one active substance is always N, N-di-n-propylthiocarbamic acid-S-ethyl-8202720 * * - 3-ester (EPTC) of formula 1, while the other one of the thio-carbamic acid derivatives of formula 2. In formula 2, represents an ethyl, n-propyl, isobutyl or cyclohexyl; R2 is ethyl, n-propyl, n-butyl or isobutyl; or and R2 together form a hexamethylene; R ^ is ethyl or n-propyl? with the proviso that R 1 and R 2 must not simultaneously be n-propyl when it is ethyl.

The herbicide preparations according to the invention contain the two active substances in a combined amount of 10-80 wt.% Of at least Sen liquid hydrocarbon with a boiling point of 150-320 ° C and 6-15 wt.% Of an additive. additive or additives, commonly used in the preparation of agricultural chemical preparations. The weight ratio of the compound of formula 1 to a compound of formula 15 is 9.5: 0.5 to 4: 6.

The use of petroleum or kerosene as a liquid hydrocarbon is beneficial, while surfactants and optionally antidotal compounds are preferably used as additives.

The following examples serve to illustrate the invention without limiting the invention thereto.

EXAMPLE I

In a round bottom equipped with a mixer, 25 different amounts of EPTC and Butylate, as stated in Table A, are weighed in, so that their total amount is 80 parts by weight. Then 14 parts by weight are stirred. kerosene, as well as 6 parts by weight. of a surfactant added. Stirring is continued until the mixture becomes homogeneous. The mixture is then filtered. An emulsifiable concentrate with an active substance content of 80% by weight is obtained.

EXAMPLE VIII

In the course of the experiment, the herbicidal. The action of the emulsifiable concentrates with only one thio-carbamic acid derivative (EPTC and Butylate, respectively) as well as of the emulsifiable concentrates in the form of the mixture of these two compounds has been studied.

The experiments were carried out in 2 plastic containers with a surface of 1.2 dm in the following manner: in each of the pots 400 g of soil was added for the definition see eg Bioldgiai Lexikon, part 3, biz. 301, Akadmiai Kiado, Budapest, weighed 1S1TJ, after which the seeds of the weeds Linum usitatissimus and Sinapsis alba were sown. Then 200 g of soil was placed in each pot on top of the seeds. Then, different dosages of the three different emulsifiable concentrates containing EPTC, Butylate, as well as EPTC and Butylate together were sprayed onto the soil, after which an additional 100 g of the soil was placed in each jar. The weeds were grown by 12 hour exposure periods (under 400 W HgMi / D daylight lamps). The pots were watered daily up to 65% of the maximum water capacity.

During the cultivation, the temperature in the greenhouse was kept on average at 24.3 ° C (maximum 26.8 ° C, minimum 2l, 8 ° C), while the average relative humidity was 57.8%. '

Evaluation of the tests was carried out on the twelfth day after the treatments, cutting the weed portion above the ground and weighing the total green 8202720-8 mass of these parts.

The calculated effect for evaluating the likely effect of the treatments performed with the combination of the two thiocarbamic acid derivatives was determined using the formula developed according to Colby S.R. / Weeds, 15, biz. 20-22 (1967) J: X.. Y.

E = _i-1 100

In the formula, X ^ represents the growth, which is measured with an applied amount of "p" in kg / ha herbicide A, expressed as a percentage of the control, represents the growth, measured with an applied amount of "q" in kg / ha herbicide B, expressed as a percentage of the control, while the probable growth - the added effect - when using the applied amount "p + q" kg / ha of the herbicides 15 A and B, expressed as a percentage of the control (calculated value).

The results of the experiments, the measured and calculated values, are shown in table H, from which it appears that the actual measured weight of the weeds 20 is significantly lower in treatments 2, 3, 4, 5, 6 and 7 than the probably calculated value, so when the two active substances EPTC and Butylate are used together in a ratio of 9.5: 0.5 to 4: 6, a synergistic effect can be observed.

EXAMPLE IX

As in Example VIII, the herbicidal activity of the emulsifiable concentrates with the active ingredient only EPTC or Vernolate and the mixture of these two active ingredients was investigated. The experiments were carried out in plastic pots with a surface of 1.2 dm in the following manner: 400 g of soil were introduced into each of the pots, after which seeds of Echinoclos crus-galli ("barnyard grass") were introduced. sown. The seeds in each pot were then covered with 200 g of soil. Then, by spraying, different doses of the three different emulsifiable concentrates with EPTC, Vernolate as well as a mixture of EPTC and Vernolate were applied to the soil, after which an additional 100 g of soil was introduced into each pot.

15 - The weeds were grown by exposure for 12 hours (under 400 W HgMi / D daylight lamps). Water was added daily up to 65% of the maximum water capacity.

In the course of cultivation, the average temperature of the greenhouse was 24.3 ° C (maximum 26.8 ° C, minimum 2l, 8 ° C), while the average relative humidity was 57.8%.

Evaluation of the experiments was carried out on the twelfth day after the treatments, cutting the portion of the weeds above the ground and weighing the total green mass of these parts.

The calculated effect for evaluating the likely effect of the treatment performed with the combination of the two thiocarbamic acid derivatives was determined using the formula developed according to Colby, as indicated in Example VIII.

The results of the study, the measured and calculated values are shown in Table I, from which it is clear that on the one hand EPTC and Vernolate, used separately, exhibit a weaker herbicidal action, than the herbicide preparation, which both components together contains in an identical dose. On the other hand, the actual weed weight measured is significantly lower in treatments 2, 3. 4, 5, 6 and 7 then the probably calculated value, which means that when the two active ingredients EPTC and Vernolate are used together, a synergistic effect occurs in a ratio of 97/5: 2.5-50: 50.

EXAMPLE X

Using the same methods and conditions as in Example IX, the herbicidal activity of EPTC 15 and Cycloate was tested by using them separately or together in a mixture with the weeds Echinocloa crus-galli.

The conduct and evaluation of the study are identical to that of Example IX, while the results obtained are listed in Table J.
