Description

 one

This invention relates to insect control formulations (pests of cultivated plants) and funtopathogenic fungi.

Insectofungicidal compositions containing phenol phenol as an active substance are known. However, these formulations may not always be used in conjunction with antibiotics and other pesticides.

In order to obtain a composition suitable for introduction separately or together with antibiotics and other tests, it is proposed to take the compound of the general formula as an active substance.

wherein

RI is a hydrogen atom, cyanogroup or COOH and -CORi groups,

Doryda Or lower alkyl and R4 - lower alkyl.

Compounds of this general formula are stable and can protect cultivated crops from pathogenic grlba for a long time. The fungicidal activity of these compounds is their main property. They prevent the disease, and also eradicate it 1pr. And by appearance. They are especially effective against fungal diseases of rice.

These compounds can be used with antibiotics such as Blastocidin S and Kazugamycin, as well as with pesticides such as 0.0-diethyl-8-benzyl phosphorothioate or O-ethyl-S benzylphenyl phosphorothioate, which themselves have a strong therapeutic effect. In this way, a supplementary myrophylactic and therapeutic effect is achieved.

They, in addition, can be used with 0,0-dimethyl-0 - (3-methyl-4-nitrophenyl) -phosphothioate (nitroth Sumition).

Also, compounds can be used in conjunction with copper compounds, organo-mercury compounds and organic sulfur compounds, antibiotics — streptomycin,

chloamphenicol and celocydine. They can be used with insecticides such as BHH, "Parathion," Malathion, EPN, "Dimethoat.

The described compounds can be obtained by treating 3,5-di-t / et-butyl-4-hydroxybenzaldehyde with compounds of the formula

,

In iKOTOpofi, Ri and R2 are as defined above, followed by dehydration and condensation.

As insecticides, these compounds can be used in pure form (without the addition of "omtonents"). However, it is better to use them in the form of formulations, for example, dusts, wetting powders, emulsifiable concentrates and granular preparations.

Compounds containing these compounds are very effective orogyv leaf mites that affect fruit trees, forests and vegetables, as well as against the Chevretes (coccidia) that damage stored grain, bugs and insects such as mosquitoes and flies. They possess insecticidal activity against Sapiclopterd, Hemiptera, Coleoptera.

The proposed formulations do not contain poisonous substances, are less toxic to people and livestock, do not harm the plants being cultivated, and at the same time have fungicidal and insecticidal properties.

In tab. 1 gives examples of compounds corresponding to formula (I).

Table I

The following are examples of the preparation of insecticide composition.

Example 1. 65 parts of compound No. 2, 5 parts of a wetting carrier such as polyoxyethylene alkylphenol and 30 parts of kaolin are thoroughly mixed. A wettable powder is obtained containing 65 | Vo of the active substance. Before using the powder, it is mixed with IBO, and the mixture is used for spraying.

Example 2. 50 parts of compound No. 10, 5 parts of an alkylbenzeneslfonate wettable carrier and 45 parts of diatomaceous earth are thoroughly crushed and transferred. A wettable powder is obtained containing 50% of the main ingredient. Before use for spraying, the powder is diluted with water.

Example 3. 3 parts of compound No. 8 and 97 parts of clay are thoroughly crushed and mixed. Get the dust containing the main ingredient. Dust is used without filler.

Example 4. 2 parts of compound No. 7, 2 parts of 0,0-diethylS-benzyl phosphorothioate and 96 parts of talc are thoroughly crushed and mixed. Dust is obtained, which is used without adding

nanolitel.

Example 5. To obtain dust, finely chop and mix 2 parts of compound No. 3, 0.2 parts of Blastocidin S and 97.8 parts of talc. Dust is applied in the usual way.

Example 6. To obtain dust, finely chop and mix 2 parts of compound no. 6, 2 parts. Sumition and 96 parts of talc. Dust is applied in the usual way. Example 7. 2 parts of Compound No. 4, 2 parts of 3.4 dimethylphenyl-M-methyl carbamate and 96 parts of clay are thoroughly crushed and mixed to produce a dust, which is used in the usual way.

Example 8. 2 parts of compound No. 1, 2 parts. Sumition, 0.2 parts. Blastocidin S, 0.4 parts of iron propylsenate and 95.4 parts of clay are carefully ground and displaced. Dust is obtained which is used in the usual way.

Example 9. 50 parts of compound 1, 5 hours. “Tokusila C-N (registered trade mark of Toku ma Soda K. K company), 40 hours.“ Radiolite L 40 and 5 hours. “Soprol 5029 (trade mark emulsifier produced in the sale of the company "Togo Kagaku K.-K.) carefully

mixed up. A wettable powder is obtained containing 50% of the main ingredient. The powder is diluted with water before use.

Example 10: 65 parts of Compound No. 2, 5 parts of a wettable carrier such as polyoxyethylene alkylphenol ether and 30 parts of kaolin are carefully biased and a 65% wettable powder is obtained. It is mixed with water for spraying.

Example 11. 5 parts of compounds No. 6 and 95 parts of talc are carefully ground and shifted. Receive 5%, - ny dust suitable for use.

Example 12. 4 parts of Compound No. 3, 2 parts of sodium ligninsulfonate and 94 parts of clay with a particle size passing through a 200 mesh sieve. mixed in the specified order. Then a small amount of "water" is added to the mixture and the mass is granulated. After drying, 4% granular prenarath is obtained, which is used in the usual manner.

Example 13. 15 parts of compound No. I, 65 parts of methyl isobutyl ketone and 20 parts of “Soprol 2020 (a registered trademark of an emulsifier manufactured by Togo Kagaku K.K.) is mixed

to obtain hemogenic emulsifiable

concentrate. When applied, it is diluted

water

The solution is thoroughly mixed with a powder consisting of 35 parts of talc with particle sizes passing through a 200 mesh sieve, 40 parts of clay and 20 hours of coal. The acetone is then removed by evaporation. A 5% gus dust is obtained, which is used in the usual way.

In the following examples, the test results of the proposed insectofupicidal compositions are given.

Example 15. Plants of r.is in flower pots with a diameter of 7.6 cm in the phase of three leaves are sprayed with the composition (7 ml of working solution per pot). One day after spraying, the plants are infected with Piricularia Ogougee Sag. The extent of damage to the plants is then determined. The results are shown in Table. 2

table 2

The prophylactic index is a value calculated using the following formula:

None of the compounds tested have a detrimental effect on plants.

Example 16. Test p-preventive action.

Rice seedlings are prepared on deeds of 1 L12 each. When the plants reach the stage of three to four leaves, they are dusted with test dust (3a). After one day, the plants are infected with Piricularia oryzae spores. The number of spots formed is then counted and the prophylactic index is calculated using the equation above.

Testing for therapeutic effect.

Prepare the same seedlings as described above. When the plants reach the three-four-leaf stage, they are infected with Piricularia oryzae spores. After a day, the plants were pollinated with the test subjects in an amount of 3 kg per 10 a. Then (count the number of 1p ten formed and calculate the cure rates using the same formula as the prophylactic scores were calculated.

The test results are shown in Table. 3

the bodies of each of the test dust (3 / cr / 10a), 10 days after the growth of the rice grinder was the most rapid. After 50 days, 50 plants of each case are examined. The results are shown in Table. four.

Example 18. Effectiveness of dusts against rice cicadas.

The density of the tsikadok in the rice field is determined by the method of immersion. Then the cases were dusted with each of the tested dusts (3 kg / a). After a day, take into account the surviving circus.

The results are shown in Table. five.
