Description

Process for producing herbicide control herbicide composition

The present invention provides 1,2-benzoisodiazorin-3-one-1, 1-dioxide or its sodium salt or the following general formula (I)

1,2-benzoisodiazole-1,1- wherein R is a straight alkyl group having 1 to 8 carbon atoms, N is an undecyl group, an aryl group, propynyl group, and X represents an oxygen atom or a sulfur atom Drying of crop pest control herbicide compositions characterized by mixing a dioxide derivative or rotosulfamoyl benzoic acid aryl ester (hereinafter referred to as the present compound) with 2-methyl-4-chlorophenoxy ethyl butyrate (hereinafter referred to as MCPB) It is about a method.

The present invention is a crop disease by using a compound having a different action on the crops and weeds, that is, a compound mainly having a plant interference control action and MCPB mainly having a weed action against the weeds (작물 草 作用) It aims to make efforts to halve efforts by significantly increasing the control effect and the herbicidal effect, and to increase the economic effect by reducing the usage.

The inventors of the present invention (benzoisodiazole compound) have already been developed and researched on the control of crop diseases, and as a result, it has been found to be effective in the blast disease, and thus the invention regarding the blast control agent.

Subsequently, studies on the expansion of applied pests and sexualization of the method for the present compound revealed that the compound of MCPB, a known compound, was used in combination with the present compound to have a surprising effect on the control of a very new strain It became.

In addition, the test resulted in a marked increase in the effect of more than just a blending effect on rice weeds and rice paddy.

Therefore, this invention provides the manufacturing method of the crop pest control herbicide composition (henceforth this composition) which mixed this compound and MCPB.

Specific examples of the composition are as follows.

[Table 1]

Specific Example of the Composition

The mixing ratio of the present compound and MCPB, which is an active ingredient of the present composition, is preferably 1: 0.1-2 by weight.

In the practice of the present invention, the composition may be used as it is for sleeping or plants, but in most cases a carrier is used.

As the solid carrier, clay, kaolin, talc, bentonite, cray, diatomaceous earth, siliga, calcium carbonate, calcium bicarbonate and the like are used.

As a liquid carrier, what is used as a solvent with respect to this composition, or what can be disperse | distributed or dissolved by an adjuvant is used.

Ketosine, dioxane, acetone, dimethylsulfoxide, animal and vegetable oils and surfactants.

Additives and active ingredients can be varied over a wide range. When used as a solvent, the concentration in the liquid is preferably 10PPM-2000PPM, so in the case of granules or powders, it is preferable to contain the composition in the range of 1% -30%. 10kg is recommended.

Crop disease control herbicide compositions of the present invention can be used in combination with known fungicides, insecticides, herbicides, plant growth regulators or fertilizers.

Next, an Example is described.

Example 1

Compound (1) 7% tray 89%

MCPB 1% Carboxymethyl Cellulose 3%

The above constituent materials are mixed and ground, an appropriate amount of water is added, kneaded, molded, and dried to granulate 5 kg of the three-dimensional composition per grain.

Example 2 Hydration Agent

Compound (8) 10% diatomaceous earth 65%

MCPB 2% Polyoxyethylenealkylaryl ether 2%

Cray 18% Lignin sulfonic acid 3%

The above-mentioned ingredient materials are uniformly mixed and ground and prepared to form a hydrated powder, and then, dispersed at 100-150 l per 10 pellets as a predetermined concentration.

Example 3 Powder

Compound (10) 3% Talc 96.7%

MCPB 0.3%

4 kg per 10 grains of powder is prepared by mixing and grinding the components of diacids.

Toxicity of the present composition prepared as described above was found to be extremely low and safe by oral administration to mice.

In addition, the toxicity of fish was tested as carp, and practically no fish toxicity was recognized and insecticidality was not recognized. Therefore, it can be safely used in rice field packaging.

Next, the crop pest control manufacturing effect test of this composition is demonstrated.

Test Example 1 Water White Blight Control Test

It is a time of infection by cultivating rice seedlings (cultivar, cultivation) in 1/500 apotts, and inoculating rice white germ bacillus, which was pre-cultivated in the geothermal heat of rice which reached the early stage.

The predetermined amount of the granules of this composition prepared by the method of Example 1 the next day was used to be included in the ground surface in a pot.

The irradiation measured the length of the lesion for 50 inoculation leaves of each mouth at intervals of two weeks after the present application of the composition, and calculated the control value when the control value of the untreated device was zero.

Weakness was observed at the same time.

Thus, the test was carried out in three replicates.

The test results are shown in Table 2.

Test Example 2 Blast Control Test

When the rice in the pot is grown with 4,5 sheets of the main leaf, put the rice in the pot at room temperature as it is at room temperature, inject water to the ground, soak the rice and immerse the rice prepared in the method of Example 1 Quantitatively established.

After 10 days, the seedling bacteria spore suspension was spray-inoculated when 6 sheets of leaf were grown, and after 7 days, the number of invention lesions was examined to calculate the control value when the control value of the non-treated group was zero.

All three tests were performed.

The test results are as in Table 2.

[Table 2]

Water White Confession: Plague Control Test

☆ Sankel powder was distributed by manual branching.

☆ Weak-indicates no damage to rice.

In Table 2, it was found that the present composition exhibited excellent control effect against P. vulgaris and P. febrile disease.

[Test Example 3] Paddy weed control test

Paddy soil was placed in a 1/5000 aalpot and freshwater was transplanted. After the tombs were rooted, the pots were planted in Noviye, Hirumushiro and Kayatsusri Kusa.

The hydrating agent of the present composition prepared in the same manner as in Example 2 was diluted with water at a predetermined concentration and treated so that the effective amount per 10 grains was 500 g and 200 g.

Three weeks after the treatment, weed control effects and water damage were examined.

Evaluation of the effect was performed according to the following criteria.

5: 95% or more of the herbicidal rate for the untreated apparatus (irradiation)

4: 80% or more of the herbicidal rate for the non-treatment apparatus

3: 50% or more of the herbicidal rate for the non-treatment apparatus

2: 30% or more of the herbicidal rate for the non-treatment apparatus

1: 10% or more of the herbicidal rate for untreated apparatus

0: 9% or less of the herbicidal rate for the non-treatment apparatus

The test results are shown in Table 3.

[Table 3]

Paddy weed control test

☆ (weak-indicates that no weakness was recognized in rice.)

In Table 3, it is evident that the composition exhibits excellent efficacy in controlling paddy weeds.
