Test report

Barley {iiordeum vulgare). Rye (Seeale eereale). Wheat (Trltlcum aestlvum), sticky herb (Gallum aparlne) and dead nettle that surrounds the stem (Lamlum amplexlcaule) were in a greenhouse at a height of 4 to 20 cm with the active ingredients A and B accordingly Example I of the present application and mixtures thereof, each emulsified or dlsperglerl In Liters of water per hectare. The damage to the plants was rated on a scale from 0 to 100. 100 means no emergence of the plants or complete destruction of at least the above-ground parts. the Test results are shown in the table below.

Claims (1)

Inta: AOL N 43/88
Publication day: 5.1.83 Claim: Herbicide containing a mixture of
a) a compound of the formula dlkoiyle seed weeds, monocot seed weeds or to fight cyperaceae. The mixtures can be pre-emerged and / or be used post-emergence. The new mixtures can be used as herbicides in the form of solutions, emulsions, suspensions, dusts or granules are used. The application forms depend entirely on the intended use; they should in any case have a fine distribution to ensure the effective substances. Medium to high mineral oil fractions are used to produce solutions that can be sprayed directly Boiling point like kerosene or diesel oil, also coal tar oils as well as oils of vegetable or animal origin, in the R a lower alkylresi with up to 4 C-15 also cyclic hydrocarbons, such as tetrahydro atoms means, or their salts and naphthalene, and alkyl-tertiary naphthalenes. b) 9-Hydroxy-fluorene carboxylic acid- (9). Aqueous application forms can be made from emulsions concentrates, pastes or wettable powders (spray powders) can be prepared by adding water. To the Production of emulsions can use the substances as those or dissolved in a solvent, homogenized in water by means of a wetting agent or dispersant. But it can also consist of an active substance, emulsifying or dispersing agent and possibly a solvent Concentrates are produced which are suitable for dilution with water. To finished spray liquors various types of oils can be added. Dusts can be produced by mixing or grinding together the active substances with one fei'.en carrier material can be produced. Granules can be produced by binding the active ingredients to solid carriers. In addition, dispersions that can be sprayed directly with oils can be used getting produced. The mixtures can be mixed with fertilizers, insecticides, Fungicides or other herbicides. example 1 The plants wheat (Trltlcum aestlvum), barley ^A0 (Hordeum vulgar). Sticky herb (Gallum aparlne). Chickweed (Stellaria media) and stalk-encompassing dead nettle (Lamlum amplexlcaule) were treated at a height of 4 to 20 cm with the following individual products and their mixtures, each emulsified or dlsperglert in 500 liters of water per hectare: A 3-isopropyl-2.1.3-benzo-thladlazlnon- (4) -2.2-oxide 0.75, 1.5. 2 and 3 kg / ha of active substance
B 9-Hydroxy-fluorene carboxylic acid- (9). I and 3 kg / ha of active substance
B + A 1.0 + 2.0 kg / ha of active substance The table below shows that the mixture after 8 to 12 days compared to the Elnzel-S5 active ingredients shows a better overall effect with favorable Kullurpflanze compatible. The present invention relates to a herbicide that ^ Contains a mixture of two active ingredients. It is known that substituted fluorene carboxylic acids lind Benzihlothladiazlnone have a herbicidal effect [refresh. However, their herbicidal effects are poor. It has been found that a mixture of
