SU240600A1 - INSECTO-FUNGICIDE COMPOSITION - Google Patents

Description

The invention relates to: compositions for the control of fungi (pathogens of cultivated plants) and insects, which include pyrimidine derivatives as an active ingredient.

An insect fungicidal composition is proposed which contains, as an active ingredient, compounds of the general formula

in which RI and R2 is methyl or Ri is hydrogen, and R2 is ethyl; Rs is methyl; R4 is lower alkyl with 2 carbon atoms;

X is oxygen or sulfur; R is a carbonyl or sulphonyl group linked to a lower alkyl, lower alkoxy or phenyl radical.

The pyrimidine derivatives of this invention are active against a large number of causative agents of plant diseases, especially against Phytophtora infestans on tomatoes, Sphaerotheca fuliginea on cucumbers, Erysiphe graniinis on wheat and barley, Podosphaera leucotricha and Xenturia inequine, on the wheat and barley, and in a pattern, I can go to the template, I can use the template, I can use the template, I can use the template, I can use the template, I, I, I, I, I, I, I, I, I, I, I, I will apply, I can go, I can go, I will apply, I will apply), I will apply to the template, I will help you to get rid of chromosomals, you will be able to use the pyrimidine derivatives of this invention. Piricularia orxzac- on piico, Pythium ultiniuin on peas, Fusarium cuinioruni on ishshsche.

They also possess activity against a number of insect pests: Aphis fabae, Macrosiphum pisi, Tetranychus telarius. Phacdon cochleariae, a and Aetes aegypti.

A valuable feature of the pyrimidine derivatives of the present invention is their systemic effect — the ability to interchange; 1, but to the plant and to affect pathogens of diseases and insect pests.

And the most preferred pyrimidine derivative is one in which RI, R- and R-j-methyl, R-n-butyl. and XR -, - grui na 0-CO-CJI.- ..

Insect-fungicidal cocTaiBbi can be applied to plants and the soil according to isosretemii

or seeds. They are best applied as a dustoz or grappula, in which the active ingredient is mixed with a solid carrier commonly used for this purpose (kaolin, bentonite, diatomaceous earth, talc, psc, etc.). For the table 1. Examples of compounds of the specified formula

Table 1

formulations containing a substance that improves the adhesive properties of the composition in relation to the seeds, for example, mineral oil.

The compositions may take the form of dispersible powders or grains containing, in addition to the active ingredient, another wetting agent.

The formulations may be in the form of liquid preparations, usually in the form of aqueous dispersions or emulsions containing, as well as one or several centimeters, 1Mi, also emulsifiers, stabilizers and other substances.

Wetting agents, dispersants and emulsifiers can be of the cationic, anionic or non-ionic type. Quaternary ammonium derivatives, for example cetyltrimethylammonium bromide, can be mentioned as suitable cationic agents. Suitable for anionic foods are, for example, the salt of aliphatic monoesters; Suitable ionic-type agents can be, for example, ethylene oxide condensation products with fatty alcohols, ka, oleic and cetyl, or alkylphenolamines, like acylphenol, nonylphenol and octylcresol. Other non-ionic substances are partial esters produced from long-chain fatty acids and hexitols, condensation products of these mixtures with fertilizers, for example nitric or phosphoric. In this case, it is advisable to cover them with fertilizer granules.

To produce pyrimidine derivatives in the form of .concentrates with an active ingredient content from 10 to 85%. Most often, such concentrates are produced with a content of 25-60% of the active ingredient. For practical use, they must be diluted with water to a content of 0.001-1.0% of the active substance.

Examples of the preparation of insect fungicidal compositions are given.

Example 1. Shifted (in wt.%): 10 of compound No. 1 (according to Table I); 40 ethylene chloride; 5 calcium dodecyl benzene sulfonate; 10 lubrol L; 35 Aromasol N. Got a homogeneous conscentrate emulsion | I.

Example 2. Composition. ICs in the form of grains, easily dispersed in water, was obtained by rubbing a mixture of the following composition (in%): 50 compounds No. 1, 25 disiesola T and 1.5 lubrol APN5 in the presence of water, followed by addition of sodium acetate. The mixture was dried and passed through a sieve with hole sizes 44-100 broom.

Example 3. The ingredients are ground together in the following ratios (in%): 45 of compound No. 1; 5 dispersol T; 0.5 lissapola NX; 2 cellofas B 600; 47.5 sodium acetate. A powder composition is obtained which is easily dispersed in water.

EXAMPLE 4 By mixing 50% of compound 1, 2% of mineral oil and 48% kaolp, a composition was obtained which is suitable for use as a mordant.

Example 5. Dust was obtained by mixing 5% of compound 1 and 95% talc.

Example 6. The obtained colloidal solution by grinding the components in a ball mill, followed by the formation of an aqueous dispersion. Components are taken (in%): 40 compounds No. 1, 10 dispersal T, 1 lubrol L, 49 water.

Example 7. Compositions were prepared, similar to those specified in examples 1-6, but with the content as active ingredient of compounds No. 2, 3, 4, 5, 6, 7 and 8.

Insect-fungicidal Sastavy. There were experiments to protect plants from fungal diseases and to combat them.

For the first test, the plants were sprayed so that their leaves were wetted with a solution or suspension of a preparation containing 0.05% of the active ingredient and 0.1% of the wetter. After 24 hours, the plants were inoculated with the appropriate causative agent and through

a certain time was visually determined the degree of infection of the plants.

In trials of the control of pathogens, plant leaves were inoculated with the appropriate pathogen and

The test results are presented in ta; 2. (The reductions of the “protection and un” inhibit, respectively, the action of the drug in the case of protective (prophylactic) use and in the fight (destruction) of the already pathogen of the disease).

The effectiveness of the proposed formulations was tested in the fight against these insect pests.

Subject invention
