Description

Technical field

The utility model relates to a composition that improves the action of sulfonylurea-based vegetative herbicides, bacillus turingiensisis insecticides, diflubenzuron and spinosad. It can be used on its own and can also be used to control mites and thyroid lice.

BACKGROUND OF THE INVENTION

In many cases, the effectiveness of plant protection chemicals is enhanced by specially selected enhancers that are added to the working solutions of the pesticide in question.

It is known that the widely used agricultural practice herbicides Titus 25 DF and Tel 75 VP are co-administered with the improvers Sitovet (alkyl aryl polyglycoleter) and ELO (petroleum fraction) [1].

A major drawback of ELO is its poor efficiency and difficulty in the synthesis of the active substance, which has necessitated the cessation of its production in recent years.

Sitovet is a product of BASF [2]. Non-rhythmic import of the preparation makes it difficult to use Titus 25 DF, which is the main herbicide for growing corn.

Enhancers, as excipients, not only increase biological activity, but also reduce pesticide consumption, which in some cases can be as high as 30-40%.

Their use fully meets the current requirements of integrated plant protection.

The Parak preparation, used at a dose of 900-1000 ml / dka, is known to reduce the consumption of Roundup herbicide by 30-35% per decare while maintaining its biological activity [3].

The technical nature of the utility model

The object of the utility model is to provide a composition that improves the action of vegetative herbicides based on sulfonylurea (Titus 25DF and Granstar 75DF) and insecticides based on bacillus turingiensis, diflubenzuron and spinosad. The same can be used alone to help control mites and thyroid lice.

The task of the utility model is solved by a composition that is:

85-92% mineral / petroleum / oil with CAS No 101316-72-7 having the following composition:

• paraffinic hydrocarbons 65.40%;

• naphthenic hydrocarbons 27.77%;

• aromatic hydrocarbons 6.83%;

• 8-15% surfactant with CAS No 9004-96-0 representing:

• oleic acid polyoxyethylene ester CH ₃ (CH ₂ ) ₇ CH = CH (CH ₂ ) ₇ COO (C ^ CH ^ nH, where n = 7

Synonyms:

- polyoxyethylene (7) oleate;

- polyethylene glycol 7 oleate.

The proposed composition is characterized by the following indicators:

• Appearance - oily transparent liquid;

• Content of active substance 85-92%;

• Density at 20 ° C 0.860-0.890 g / cm;

• Flash point in an open crucible not less than 150 ° C;

• Emulsion resistance of 5% emulsion - for 1 hour not more than 2 cm ³ .

The composition is administered by:

• at a working concentration of 0.15-0.2% to the working solution of vegetative herbicides based on sulfonylurea:

• Titus 25 DF (rimsulfuron) 4-6 g / dka;

• Granstar 75 DF (tribenuron-methyl) 12.5 g / dka;

• Addition of the composition at doses of 50 ml / dka to 150 ml / dka to the working solutions of insecticides based on bacillus turingiensis, diflubenzuron and spinosad;

• the composition used alone as a means of combating the wintering stages of fruit mites and thyroid lice at a concentration of 2-3%.

Advantages of the composition:

• improves the adhesiveness of herbicides to the leaf surface of weeds;

• enhances the penetrating ability of

1238 Ul herbicides in plant tissue of weeds;

• improves the herbicidal activity of sulfonylurea-based preparations against economically important cereals and deciduous weeds;

• non-toxic to humans, warm blooded organisms and beneficial fauna.

Examples of implementation of the utility model

The utility model is explained as follows.

Example 1. Composition Efficiency as a Sulfonylurea Based Vegetable Herbicide Enhancer

Under field conditions and moderate humidity (maximum field moisture content of 70-75%), the herbicidal activity of the preparation Titus 25DF was tested, applied together with Composition as a maize enhancer in the development phase of the 4th-8th leaf against:

• Annual rye weeds:

- seed balur (Sorgum halepense) in leaf phase 2 - 4;

- green bush (Setaria viridis) in phase 2 - 4 - 4;

• Annual annual deciduous weeds (Amaranthus retroflexus) in phase 2 - 4 - 4.

Granstar 75DF preparation, co-administered with the Composition, was tested for wheat in the breeding phase against:

• Annual annual deciduous weeds (Amaranthus retroflexus) in phase 2 - 4 - 4.

Size of test plots - 20 t ² , number of repetitions - 4.

Treatment was performed with a back sprayer at a rate of 601 / dka sulfonylurea was counted against the listed weeds prior to treatment in the respective embodiment.

The data in Table 1 show that the composition administered at a dose of 150 ml / dka to Titus 25DF working solution increases the herbicidal activity of the preparation by 15%, respectively, compared to its use alone against annual wheat weed balur. The same trend is observed in the variants with Balur of rhizomes (perennial cereal weeds), where the increase in herbicide activity is 13.7% with Titus 25 DF.

Table 2 lists the results of testing the effect of the composition as a herbicide enhancer against weeds and green bush.

The composition, added at a dose of 150 ml / dka to Titus 25 DF working solution, enhances its herbicidal activity against annual broadleaf weed, reaching 100%. Against the one-year-old deciduous weed, the simple sincere trend is similar. The composition improves Granstar 75 herbicide activity by 14%, respectively.

EXAMPLE 2 The example relates to the use of the composition as a Bacillus Thuringians and diflubenzuron insecticide enhancer.

The efficacy of the formulation as an enhancer of the preparations Dimilin 480CK (active substance diflubenzuron) and Dipel (active substance bacillus turingiensis) was tested.

The experiment was carried out in laboratory conditions on caterpillars of a pine procession: for each variant, 100 caterpillars were counted, distributed in 4 repetitions of 25 pieces each in entomological cells. The treatment was carried out using a hand sprayer.

Efficacy is defined as the percentage of caterpillar mortality after treatment. The results are shown in Table 3.

Example 3. The example relates to testing the composition on its own as a means of combating harmful mites, thyroid lice.

Effectiveness of composition against winter eggs of red fruit moth and winter stages of California thyroid lice.

The experiment was based on isolated branches of apple trees attacked by winter eggs on a red fruit mite. For the reference, the preparation Arborol with the active substance DNOC was used. 1000 winter eggs are pre-listed for each variant.

The branches were treated with a 3% solution of the formulation, stored outdoors for a period of 12 days, then placed in a thermostat at 23 ° C and 90% relative air humidity. The hatching of eggs under these conditions is completed within 8 days. The number of hatched larvae counts the mortality of winter eggs. The results are reflected in Table 4, which shows that the proposed composition exhibits high acaricidal activity, resulting in 98.0% egg mortality.

The effectiveness of treating winter eggs with the composition prevents damage to the red fruit moth during the growing season, saving 5 to 2 to 3 treatments.

Applied as a winter spray for fruit trees against California thyroid aphid, the composition shows an efficiency of 98.6% mortality.
