The invention relates to a weed killer for use in rice fields.

For use in replanted rice fields, pentachlorophenol, diphenyl ether, and the like are because of them excellent herbicidal properties when used in the early stages of growing Plants for combating weeds are generally known. Furthermore, DCPA and SWEP.M, a Mixture of 20% methyl N- (3,4-dichlorophenyl) carbamate and 0.7% ethyl (2-methyl-4-chlorophenoxyacetate) used as a weed killer. However, these are only used when the plants have a certain Have reached growth stage. However, the use of DCPA requires a full derivation of the Water from the rice fields before its application. If the water removal is insufficient, delivers DCPA has only had insufficient success in killing weeds. In this context, however, it is important to point out that it is extremely difficult in practice. Completely remove water from rice fields, like that that in practice DCPA is rarely used. SWEP.M can also be used in those under water Fields are applied, but its herbicidal and phytotoxic properties versus rice plants vary considerably depending on the particular temperature and the soil conditions. In other words, the herbicidal properties of the remedy will be at at lower temperatures, the reverse effect of the agent at high temperatures appears very clearly. On the other hand, in rice fields that are continuously under water, the agent enters the soil and is absorbed by the roots of the rice plants, causing damage the same caused.

When SWEP.M in combination with carbamates or organic insecticides based on phosphorus is used, there is a big problem in practical use because the rice plants be seriously harmed. It is therefore very desirable to have a new herbicide develop that has stable effects in the removal of the weeds that is already to a certain extent Has grown to a degree without being phytotoxic to the rice plants.

The invention is therefore to provide a new weedkiller with the specified Properties that avoids the disadvantages indicated above.

From German Offenlegungsschriften 20 19 491 and 19 43 983 and US Pat. No. 36 71 216 are herbicidal mixtures known for use in rice fields, which a thiocarbamate compound and a contain another herbicide.

The weed killer of the present invention can be used in conjunction with solid carriers, like thinners. Using fillers and the like will. If necessary, the herbicide can be in the form of a moistened powder or be used in the form of grains with the addition of auxiliaries, such as stabilizing, dispersing, suspending agents, sprays, penetrants. Moistening agents and the like according to the invention can in the form of mixtures with agricultural chemicals, such as fungicides, insecticides or other weed killers or fertilizers such as urea, ammonium sulfate. Ammonium phosphate, potassium salts or Bodenbeeinfiussungsmhteln u. The like. Be applied. When the weedkiller according to the invention is in the form of grains, it is it is desirable that these grains contain 1-20% by weight of the composition according to the invention. If the agent is in

Is in the form of a wettable powder, e < Contains 10 - 50% active substance.

The weed-killing effect of the mass according to the invention emerges from the following experimental examples.

Experimental example 1

3.3 kg of soil, which contains a number of weeds that naturally grow in rice fields, are removed in 5000c ( Introduced Wagner container. The soil will be 0.8 g of nitrogen. Phosphoric acid and potash in the form Fertilizers are added, after which the sufficient amount of water is added. The mix works vigorously stirred, whereupon the Wagner containers are exposed to a sprinkling.

On the other hand, rice seedlings are grown in the 3-leaf stage in the greenhouse. Two bundles of rice plants, in front of which each has 2 seedlings, are planted at a depth of 3 cn in each container. Then 200 mg of barnyard grass seeds are sown over the bottom of each container and mixed with the surface of the soil. Then the containers for germinating the seeds are placed in the hothouse? brought. Fifteen days after planting, weeds had grown in the first container, including barnyard grass with an average of _2/2 leaves and a height of 5 to 10 cm. Cypcrus difformis in cinci 3-5 cm high, Monochoria vaginalis 2-5 cm high. Rolala Indica at a height of 2-5 cn and Dopatrium Junccum also at a height of 2-5 cm. A certain amount of NOPA or a granulate of compound 1 or a mixture of both compounds, as indicated in Table 1, was then added to the water in each container. One month after the treatment, the remaining part of the weeds was examined. The results are shown in Table 1. During the experiment, the water depth in each container was kept at 3 cm.

It can be seen from the above results that the ts Weed killers according to the invention have very considerable weed affecting effects own. The weed killers can be easily obtained as shown in the following examples individual can be seen. All parts given in the examples are parts by weight.

example 1

25 parts of NOPA, 25 parts of compound A, 45 parts of bentonite and 5 parts of sodium dodecylbenzenesulfonate are mixed together to obtain 100 parts of a wettable powder.

Example 2

7 parts of NOPA, 7 parts of compound B, 83 parts of talc, 2 parts of polyoxyethylene glycol monolaurylate and 1 part of a naphthalene sulfonai condensate are mixed with one another mixed. The mixture obtained is made in the usual manner using a granulating machine granulated, 100 parts of granules being obtained. ss

Example )

5 parts of NOPA, 7 parts of compound D, 86 parts of talc and 2 parts of polyethylene alkylphenyl ether mixed together. The mixture is made in the usual (10 manner using a granulating machine granulated, 100 parts of granules being obtained.

I! e i s ρ i e I 4

20 parts of NOI'A,! () Parts of compound I-, 4 ^r ) parts of talc and ^r > parts of a naphthalene .S'.il'onate condensate are mixed with one another, 100 1 parts of a wettable powder being obtained .

Example 5

30 parts of NOPA, 30 parts of compound F, 2 parts of sodium lignosulfonate and 38 parts of talc are used mixed together to obtain 100 parts of a wettable powder.

Example 6

6 parts of NOPA, 7 parts of compound G, 40 parts of bentonite, 44 parts of talc, 2 parts of sodium lignosulfonate and 1 part polyoxyethylene sorbitan alkyl ester are mixed together. The mixture is made in the usual manner using a granulating machine granulated, 100 parts of granules being obtained.

Example 7

6 parts of NOPA, 7 parts of compound H, 84 parts of talc, 2 parts of sodium lignosulfonate and 1 part Sodium dodecylbenzenesulfonate are mixed together. The mixture is taken in the usual way Using a granulating machine, granulates 100 parts of granulate.

Example X
